+---------------------------
+## Information
+---------------------------
+This is a small utility mod which adds some new animations to the default animations found in player_api animations, the new animations are:
+
+	|Animation| Start | End | FPS |
+	|---------|-------|-----|-----|
+	|Swim     |  246  | 279 |  30 |
+	|Swim Atk |  285  | 318 |  30 |
+	|Fly      |  325  | 334 |  30 |
+	|Fly Atk  |  340  | 349 |  30 |
+	|Fall     |  355  | 364 |  30 |
+	|Fall Atk |  365  | 374 |  30 |
+	|Duck Std |  380  | 380 |  30 |
+	|Duck     |  381  | 399 |  30 |
+	|Climb    |  410  | 429 |  30 |
+	
+ 	
+		
+I have done my best to trigger the animations in the correct circumstances when viewing the player model in 3rd person. 
+
+I have only tested this against minetest versions 5.0 to 5.6
+
+Mod now works with just player_api, 3d_armor is an optional depends.
+
+Works with simple_skins - https://forum.minetest.net/viewtopic.php?f=11&t=9100
+
+Works with skinsdb - https://forum.minetest.net/viewtopic.php?t=17899
+
+Works with clothing 2 - https://forum.minetest.net/viewtopic.php?p=395157
+
+When using skinsdb capes must be supplied by clothing 2.

+
+---------------------------
+## Mod explanations and interactions   
+---------------------------
+**player_api**
+fly,swim,crouch,climb animations work, enabling capes will do nothing as you cant wear them
+
+Below here assumed you stil have player_api enabled/installed:
+
+**simple skins**
+fly,swim,crouch,climb animations work, enabling capes will do nothing as you cant wear them
+
+**3d_armor**
+You have the option to have capes on or off upto you, capes are considered armor
+
+**3d_armor and simple_skins**
+You have the option to have capes on or off upto you, capes are considered armor
+
+**skinsdb**
+Fly,swim,crouch,climb animations work, enabling capes will do nothing as you cant wear them
+
+**3d_armor and skinsdb**
+Fly,swim,crouch,climb animations work you can enable capes but they wont be visible on your character but will still provide any bonuses
+
+**3d_armor, skinsdb and clothing 2**
+Fly,swim,crouch,climb animations work, visual cape provided by clothing_2 however can also enable capes but they wont be visible and it's a bit strange wearing two capes. So recommened left disabled.
+
+
+---------------------------
+## Animation rules/triggers    
+---------------------------
+Swimming - You must be in at least 2 nodes depth of liquid/flowing liquid and moving otherwise your character will simply wade through the liquid or float (stand). If you sink close to the bottom while submerged in the liquid your character will automatically stand on the bottom. 
+
+Swim through - Hold shift down while swimming, you will sink but will also now be able to swim through 1x1 tunnels.
+
+Flying - Character/player must have fly_privs you must have at least 2 nodes of airlike nodes between you and the ground otherwise your character will simply/stand or walk ready to land. You also need some type of movement horizontally to trigger the animation otherwise your character will simply stand in the air to emulate hovering.
+
+Falling - Character/player must have 4 nodes of airlike nodes between them and the ground. Easiest to trigger if fly_privs have been removed but you can fall with fly_privs. Max falling speed is set by terminal velocity, however holding shift down will let you exceed terminal velocity.
+
+Crouching - Press shift while standing in the open and then walk forward.
+
+Crouching under - Simply walk through a gap 1.5 nodes tall. Player/character must be facing the space and walking forwards.
+
+
+---------------------------
+## Turn off Animation or Crouch Rule    
+---------------------------
+From MT Main Menu go to "Settings" then "All Settings" then "Mods" then "3d_armor_flyswim"
+
+**capes_add_to_3darmor** - Default is enabled - Makes capes an armor item avaliable via 3d_armor (1 test cape included)
+
+**example_cape** - Default is enabled - The example cape "Someones Cape" is avaliable which grants fly_privs when worn and a 100% speed increase
+
+**fly_anim** - Default is enabled - Will show the flying animation
+
+**fall_anim** - Default is enabled - Will show the falling animation
+
+**fall_tv** - Default is 100 - This is terminal velocity, 100 represents approximatly 100kp/h however player/character speed will oscilate around this speed. Without this limit when falling characters simply accelerate endlessly (until they hit chunk load edge). 
+
+**swim_anim** - Default is enabled - Will show swim animation
+
+**swim_sneak** - Default is enabled - Will allow character/player to swim through a hole 1x1 in size when underwater. 
+
+**climb_anim** - Default is enabled - Will show climb animation
+
+**crouch_anim** - Default is enabled - Will show crouch/duck animation
+
+**crouch_sneak** - Default is enabled - Will allow character/player to walk through a gap 1.5 nodes high when on land.
+
+---------------------------
+## Why are Capes Included?     
+---------------------------
+I found it best to keep capes included in this mod with the option to enable or disable. This is because capes needs the new b3d player model so they
+are displayed as part of armor instead of part of the player. However as I didn't want to force anyone into using capes as armor items I created a second
+optional player model which keeps capes with the player textures.
+
+The above would create a circular dependancy if capes was it's own mod. Capes would  have a dependency on Fly/Swim but Fly/Swim needs to know if Capes mod 
+is present so as to load the correct b3d player model.
+
+Given the above I have kept capes inside this mod with an option to enable/disable it under Settings>>All Settings>>Mods>>3d_armor_flyswim by default capes are set to Enabled/true
+
+Capes provide minimal additional armor, about half as much as wooden boots by default. 
+
+--------------------------------------------
+## What nodes are set as Flyable/Swimmable?       
+--------------------------------------------
+Any node which has the drawtype set as "airlike", "liquid" and "flowingliquid" will automatically be flyable or swimmable.
+
+Big thanks to Gundul for pointing out a better way to do this.
+
+--------------------------------------------
+## Headanimation is incorporated      
+--------------------------------------------
+I have incorporated "headanim" mod content by LoneWolfHT as it was easier to include and then customise for this mod than try to interface
+with "headanim". Full credit to LoneWolfHT for the functionality. I did modify the functionality a little so visually when in 3rd person view 
+Sams head will:
+
+~ Regular animations when looking down Sams chin now rests on his chest (about a 60 degree angle).  
+~ Regular animations when looking up Sam only bends head back to the same 60 degrees.   
+~ Swimming and flying you can look down full 90 degrees, straight ahead 0 degrees, however head motion is restricted to 30 degrees back.  
+
+Make sure you disable "headanim" if you have it installed, although I found no serious issues with both enabled the mods
+could fight one another for control of head position.

-# Character Animations (`character_anim`)
-
-Animates the character. Resembles [`playeranim`](https://github.com/minetest-mods/playeranim) and [`headanim`](https://github.com/LoneWolfHT/headanim).
-
-## About
-
-Depends on [`modlib`](https://github.com/appgurueu/modlib). Code written by Lars Mueller aka LMD or appguru(eu) and licensed under the MIT license.

-## Features
-
-* Animates head, right arm & body
-* Support for arbitrary player models, as long as `Head`, `Arm_Right` & `Body` bones exist
-  * If any of these bones do not exist, it will still try to animate the remaining bones
-* Advantages over `playeranim`:
-  * Extracts exact animations and bone positions from b3d models at runtime (no complex installation)
-  * Also animates attached players (with restrictions on angles)
-* Advantages over `headanim`:
-  * Provides compatibility back until Minetest 0.4.x (as opposed to `headanim` supporting only 5.3+)
-  * Head angles are clamped, head can tilt sideways
-  * Animates right arm & body as well

-
-### `models`
-
-Other models, same format as `default` model
-<!--modlib:conf-->
-
-## API
-
-Minetest's `player:set_bone_position` is overridden so that it still works as expected.
-
-### `character_anim.set_bone_override(player, bonename, position, rotation)`
-
-The signature resembles that of `set_bone_position`. `bonename` must be a string. The following additional features are provided:
-
-* Using it like `set_bone_position` by setting `rotation` and `position` to non-`nil` values and using `""` to set the root bone
-* *Setting only the bone position* by setting `rotation` to `nil` - bone rotation will then be model-animation-determined
-* *Setting only the bone rotation* by setting `position` to `nil` - bone position will then be model-animation-determined
-* *Clearing the override* by setting both `rotation` and `position` to `nil` ("unset_bone_position")

+# Cozy Lights
+
+Improves the way light sources(torches etc) behave and allows to create huge lights, literal projectors with just a mouse click, light map will be computed for you.
+
+Early alpha, but at least NotSoWow, Sumi, MisterE, Agura and Sharp have expressed curiosity, that already makes six of us, good enough for release. Feedback, suggestions, bug reports are very welcome. At this dev stage Cozy Lights can be good for builders in creative mode, singleplayer survival is somewhat ok, multiplayer is not yet recommended, unless it's 2-5 players or just schematics with cozy lights and no functionality.
+
+**Light sources illuminate bigger area with default settings:**
+
+![cozy nodecore](https://raw.githubusercontent.com/SingleDigitIQ/media/main/cozy_nodecore.gif)
+
+Voxel light maps are a complete game changer - it is almost like going from 2d to 3d in terms of depth. You now have 14 shades for every visible building block, and it does not have to register 14 versions of every building block. Cobble only challenge has got a whole lot easier, something fun to look at with the least fun texture is possible now with just this mod :> Disabling smooth lighting might can make for an interesting aesthetic in some cases.
+
+You can also build these lights just like you do with any structures, in other words, place invisible blocks of light of all possible engine light levels block-by-block. Tools are coming soon to make this process more user-friendly, right now you will need to make them visible and interactable in debug mode.
+
+It is eventually supposed to become accurate enough so that if you learn how to draw, you will have an easier time understanding how depth and shadows work and what can be done with them.
+
+**Cozy wielded light:**
+
+![cozy wielded light](https://raw.githubusercontent.com/SingleDigitIQ/media/main/wielded_cozy_light_compressed.gif)
+
+**WARNING:**
+
+**1. after removing Cozy Lights from your world you will be left with spheres of unknown nodes. Easiest could be to reenable the mod and call ```/clearlights``` in all locations Cozy Lights are active.**
+
+**2. if you have override_engine_lights enabled, then in case you ever remove Cozy Lights mod from your world, you will be left with broken lights. To fix it, you will need to use the mod fixmap or anything that updates/fixes engine lights. override_engine_lights is disabled by default, so it should be safe.**
+
+## Known issues
+
+1. worldedit:placeholder nodes can prevent light map from generating correctly and this currenly happens without notice or options provided. Current workaround is to define a worldedit region and run ```//replace worldedit:placeholder air``` before adding lights to the scene. This issue also involves cozy wielded light, wordedit placeholders can appear anywhere if the mod is active. There can be other invisible nodes from some mods and games which would interfere with light map.
+
+2. You will have to disable K Ambient Light to use Cozy Lights, together, they are not recommended for now.
+
+3. Light emitting liquids always straight up ignored, light emitting airlikes too
+
+4. When there are too many light sources in a generated area, it gets ignored. If you run /rebuildlights in such area, it will attempt to do so, but probably would need too much time
+
+5. If you are moving too fast(creative or falling from above) and its first time you visit many areas, generation will not look like it's immediate
+
+6. Some lights are still being missed in generated mapblocks
+
+*For what it does it's quite fast, it is supposed to somehow get even faster. I have recently discovered that my CPU is 10(!) years old and it's actually usable on my PC. Would appreciate if somebody with a beast PC would try this mod out and post a couple of benchmarks, and also if some phone poster will try to do the same*
+
+## Light Brush
+
+![creating a massive light with a click](https://raw.githubusercontent.com/SingleDigitIQ/media/main/light_brush_early_alpha_optimized.gif)
+
+*Click or hold left mouse button* to draw light with given settings. Light Brush' reach is 100 nodes, so you can have perspective. Note: with radiuses over 30 nodes as of now mouse hold won't have an effect.
+
+*On right click* settings menu opens up. The menu has hopefully useful tooltips for each setting. You can set radius, brightness, strength and draw mode. There are 6 draw modes so far: default, erase, override, lighten, darken and blend.
+
+![light brush settings](https://raw.githubusercontent.com/SingleDigitIQ/media/main/concise_light_brush_settings_smol.jpg)
+
+## Chat Commands
+
+```/cozysettings``` opens a global settings menu for cozy lights, here you can adjust node light sources like torches, meselamps, fireflies, etc to make it work better with potato or make light reach mad far and stuff. Some settings which you can find in Minetest game settings for the mod are still not present here(like override_engine_lights which makes everything nicer). These changes persist after exiting and re-entering the world again.
+
+![Global Cozy Lights Settings](https://raw.githubusercontent.com/SingleDigitIQ/media/main/cozysettings_or_zs_smol.jpg)
+
+Currently max radius is 120 for commands below, if your value is invalid it will adjust to closest valid or throw an error. Some potatoes might experience issues with big radiuses. Eventually max radius will be much bigger.
+
+```/clearlights <number>``` removes invisible light nodes in area with specified radius. Helpful to remove lights created with light brush. Example usage: ```/clearlights 120```
+
+```/rebuildlights <number>``` rebuilds light map in an area with specified radius. Useful in case you changed the settings or accidentally broke some lights by other commands or by mining in debug. This can be slow if there are lots of light sources in the area with far reaching light. Example usage: ```/rebuildlights 40```
+
+```/fixedges <number>``` fixes obstacles' opposite edges for light map in an area with specified radius. Default algorithm sacrifices accuracy for speed, because of that the lights can still go through diagonal walls if they are only one node thick, and as of now they can sometimes light up an edge(1 block from a corner) of the opposite side of an obstacle. With this command you are supposed to be able to fix it, but currently it's weird, broken. You can use it but the result wont necessarily look good.
+
+```/cozydebugon <number>``` makes all cozy light nodes visible and interactable in an area with a specified radius. With it you can also basically build lights just as you would with any other structures before the tools for that are available.
+
+```/cozydebugoff <number>``` makes all cozy light nodes invisible and non-interactable again in an area with a specified radius.
+
+```/optimizeformobile <number>``` removes all cozy light nodes which do not touch a surface of some visible node, like cobble for example. It is maybe useful, because default algo spreads light in a sphere and lights up the air above the ground too, which might be a bit challenging for potato and mobile to render reliably, they might experience FPS drops. Good if you are building a schematic for a multiplayer server. This option might slightly decrease the quality of light map, example: you have a light node with strength of 7 above the ground, and that ground is visible because of that, but after using this option that light node will be removed, so that part of the ground might be left in complete darkness. Basically might make some places darker.
+
+```/spawnlight <brightness float> <reach_factor float> <dim_factor float>``` spawn a light at your position which does not use user friendly light brush algo, but ambient light algo. "float" means it can be with some arbitrary amount of decimals, or simple integer
+
+```/daynightratio <ratio float>``` change Minetest engine day_night_ratio for the player who used the command. ```0``` is the darkest night possible, you can observe how dark it can be on the screenshots, was useful in testing, probably will help with building too. ```1``` is the brightest possible day. Some gradations in between are maybe under appreciated and seem pretty moody, I guess that would depend on a texture pack.
+
+```/cozyadjust <size number> <adjust_by number> <keep_map number>``` change brightness of all cozy light nodes by adjust_by value in the area of size. Adjust_by can be negative. Keep_map is 1 by default and can be omitted, when it's 1 and adjust_by will result in a value out of bounds of 1-14(engine light levels) even for one node in the area, the command will revert(have no effect at all), so that light map will be preserved. If you are ok with breaking light map, type 0 for keep_map.
+
+
+Shortcuts for all commands follow a convention to easier memorize them:
+
+```zcl``` - clearlights
+
+```zrl``` - rebuildlights
+
+```zfe``` - fixedges
+
+```zdon``` - cozydebugon
+
+```zdoff``` - cozydebugoff
+
+```zofm``` - optimizeformobile
+
+```zsl``` - spawnlight
+
+```zs``` - cozysettings
+
+```zdnr``` - daynightratio
+
+```za``` - cozyadjust
+
+## Supported mods and games
+
+Most of the most popular ones on paper, but its early alpha, so it can still be broken. It's not just popular ones, actually no idea how many it supports, some of them are not even on ContentDB.
+
+For definitely supported games, check the section of supported games on ContentDB, or mod.conf, if the game is in a list then support is full for what the mod can currently do, current *known* exceptions are:
+
+**Nodecore** - partial support, light map does not update for dynamic light sources(the ones that change brightness over time)
+
+**Age of Mending** - partial support, too many light sources in caves sometimes, and so far Cozy Lights cant process that without completely freezing everything for some time
+
+**Piranesi** - does not seem to work at all, probably something schematic related
+
+**Shadow Forest** - it works as intended, but there is only campfire to make cozy, wont feel like an upgrade
+
+If a mod or a game you like is not supported or there are some problems not listed here, tell me immediately. You can just drop a list of games/mods you have issues with in review. Eventually cozy lights' support will attempt to balance the overall feel and look of the game/mod with meticulous consideration, but we are not at that stage yet.
+
+## For Developers
+
+There are like I think 5 algo versions of drawing lights or I refactored that, because I never heard of DRY, never happened. All algos sacrifice accuracy for speed and miss some nodes for huge spheres.
+
+*Plans for API:*
+
+- You will be able to override cozylights' global step, disable it and call it from your global step
+
+- You will be able to override any default settings
+
+- Register unique settings for specific nodes
+
+## Todo
+
+- is it possible to have trees grow within the radius of a light block like torches
+
+- add undo
+
+- figure out what to do about lights going through diagonal, one node thick walls. also still somehow manage to keep algo cheap
+
+- Optimize memory usage, use several voxel manipulators for biggest lights, will be slower but much more stable, also increase max radius to even more mentally challenged value
+
+- see what can be done with race condition of wielded light and node light
+
+- save brush settings in item metadata and change icon somehow to resemble the settings
+
+- add /disableongen
+
+- all queues should be saved in case of server shutdown, so they can be resumed
+
+- add /ignore certain block
+
+- algo for many adjacent lights
+
+- see what can be done about snow and slabs not passing the light through
+
+- make dropped items emit cozy light if they have light_source above 0, just like in original wielded light mod
+
+- make sure bigger lights wont go unnoticed in on_generated and schematic placement. apparnetly on generated can support lights up to 80 if max area radius is 120
+
+- stress test it with heavily modded worlds, possible problem: luajit ram limit for default luajit on linux?
+
+- illuminate transparent liquids too if possible without making it look weird, except dont make floodable light sources work underwater just like in original wielded light
+
+- fix nodecore dynamic light source not updating the brightness/radius
+
+- add privileges so schematics can be used on multiplayer server
+
+- parse minetest forum for optional_depends
+
+- add inventory images for lights and debug lights, make them only available in creative
+
+- make darkness nodes, wielded darkness, Darkness Brush
+
+- add static natural scene(stop the time, fix the sun/moon in one position, update the area accordingly)
+
+- raytracing
+
+- allow people to run cpu and memory-friendly minimal schematic support version, for multiplayer servers for example
+
+- if certain treshold of light source commonality in an area is reached, those light sources should be ignored
+
+- would it be possible without too much work to programatically determine global commonality of a node from mapgen?
+
+- add optional more pleasant day/night cycle
+
+- add optional sky textures
+
+- add multiplayer/mobile settings(very little light nodes, very simple light map), and mid settings(more or less okayish), max is default
+
+- move to base "unsafe" methods for tables? seems like luajit optimizes it all away and it's useless to bother?
+
+- try spread work over several loops and try vector.add
+
+- maybe three types of darkness nodes, ones that are completely overridable with cozylights, and ones that arent(make a darker light shade), and ones that completely ignore cozylights
+
+- lights auto rebuild on first load after settings change?
+
+- make a table for existing decoration nodes
+
+- make sure spheres of big sizes dont miss too many blocks
+
+- give light sources metadata, so when nearby light sources are destroyed you can find and rebuild easily, also give metadata to light brush epicenter for the same reason
+
+- maintain files in which you record light source positions, which can be quickly grabbed to rebuild lights if there is a removal
+
+- add cone light blocks, so those lights can be built on top of each other to make static lights from old games
+
+- add light grabber tool, Light Excavation Tool 9000 TURBO V3, so that the light wont be selectable without it
+
+- add Consumer Grade Reality Bending Device to create preset nodes with chosen qualities
+
+- add global step override api, ability to implement cozylights global step into a game/other mod global step more efficiently, maybe add generic global step call like mainloop or mainstep, see what other games do with it, choose or create convention for this i guess
+
+- add handle_async where it makes sense
+
+- ci for optional_depends auto update according to content db mods/games updates and releases
+
+### Some expensive notes stackoverflow will never tell about LuaJIT to you or to future me. Summing up my discord rambling because COVID made me forget some of Lua I tried before, so I am writing it down for now.
+
+TLDR: LuaJIT is certainly impressive in some parts, however I would rather refrain from using it for absolutely anything that implies even a bit of performance, and unless there is no way to avoid it, deprecate Lua as a terrible inconvenience and never look back. It's too slow, and when you try to squeeze anything out of it, it loses most of its appeal/narrative, it even loses purpose. If still too many words, remember just this about Lua: never try to optimize Lua too much, it's never worth it, and, just let Lua iterate.
+
+1. While being smol, it still fails to outperform another state of the art JIT - JS V8. And thats given that JS V8 is big tech kind state of the art, which means there is certainly at the very least a significant room for improvement. Advantage of Lua in comparison to V8: less RAM consuption for small programs, so it's reasonable to run a bit of LuaJIT on weak hardware, like phones, watches, some smart-whatever, robots. In that case it's not the worst choice.
+
+2. Readability syntax is a meme, I am here to code, not to shitpost, I prefer completely different state of mind from that, something very different, like curly braces and what not.
+
+3. Lua bytecode, same way as Python, keeps function and variable names uncompressed. You could argue but hey that means we can at least restore the original file almost one-to-one from bytecode? Who needs that really, when RAM efficiency is 25%(!) better after using a minifier, and if you use minifier, you abandon debugging and readability(just like in Python, which is a meme language too, and it's typical very readable one letter long variable names). This is how as codebase grows, Lua loses it's only advantage over V8. Hence technically peak Lua is a joke.
+
+3. Peak performance Lua cant be, without a lot of effort, transpiled and rewritten into peak performance compiled language, since it's behavior and optimization techniques are drastically different and by that I mean next level drastically different. Therefore it's not as good for prototyping as JS V8, unless you denounce the very idea of optimizing Lua as heresy.
+
+4. LuaJIT does so much behind your back, so that performance becomes exhaustingly unpredictable. Stuff that works in nearly any other language does not work here, and you will often have to rely on profiler no matter how good you are with Lua, rather than act according to assumptions based on fundamentals. You could even say that what you have to do when Lua performance is concerned, is literal trial and error. You then find a sweet spot and never touch that part of the code again, because it's impossible to reason with/reliably reproduce/improve upon.
+
+5. While you could cope that CPU just does not have enough cache and all, clearly, LuaJIT is best at optimizing *simple* loops. Branches, hash look ups, math? Try your best to decrease the amount for all of those in a loop. It appears that Lua would rather iterate uselessly over and over again the same entries, than have a branch to cut amount of iterations/operations in general. Optimization tip is basically this: try to break down a complicated loop into several simpler loops. LuaJIT is ridiculously fast with simple loops.
+
+6. It appears that most popular object positioned most efficiently in memory. I am not entirely certain how exactly does that happen, because I didn't study LuaJIT source much since it's underwhelming performance in anything remotely complicated leaves me feeling powerless, so it's not fun. A hack could be a loop that interacts with an object on startup, if you call/interact with the object enough times it will be slightly faster. It is noticeable in massively expensive loops.
+
+7. If you know you are guaranteeed to have an object consume more RAM during runtime, you may want to preallocate if the codebase is complex enough. Well, at least this behavior can be fully expected based on fundamentals.
+
+8. Refrain from having too many hash look-ups, it's not slow by itself, but apparently it clogs cache fast, so sometimes adding just one hash look-up can result in a massive drop in performance. Surprisingly, refrain from having too much of one of the most simplest parts of LuaJIT - math, best is to pull numbers out of Lua' ass, like in Cozy Lights. Luckily predictably this time, branches are the worst in a loop, however this time they are bad even if they cut a massive amount of operations. So you have to balance here, peak performance Lua demands abandoning DRY completely, but that also means you have to consume more RAM. Ideal Lua loop is when it does nothing at all, just iterates. Just let Lua iterate.
+
+9. You can obviously somewhat control cache with local variables, but there is a catch, it only gives somewhat coherent performance results if the loop is very simple.
+
+10. Apparently because of memory allocation being complex in LuaJIT, it can crash during trying to allocate too much in one go as if it's in the earliest dev stage and not ready for prod. JS V8 maybe leaks, but at least does not crash just like that.
+
+11. To make any good use of ffi types, you have to be aware of the fact that amount of types in function context will affect it's performance. More types = slower. So same as V8, it might optimize smaller functions better, but not necessarily, it depends: if it's one lua type number and there is a lot of work to do for that type, then you better off having a big one surely. Ffi is not a simple plug-and-play for previously optimized pure Lua algo, you may need to restructure your code to ensure more types dont clog the cache. And with Minetest API it may end up being useless.
+
+12. Offloading work to C has it's caveats. If you are doing it through ffi and need to manipulate a lot of data, like vm_data in Cozy Lights example, while your algorithm itself will be faster, if like with Minetest example, the api expects lua table and only that, you will have to interpret C results, run a loop to make a lua table, and that part is so extremely slow, you might end up with slower code overall. In less complicated cases it's useful.

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:

+Emote - a player emote API
+##########################
+
+This mod aims to provide an API for player model animations such
+as sitting, waving, lying down, as well as some providing chat
+commands for the player to use these "emotes".
+
+## API
+
+The emote API consists of several functions that allow mods to
+manipulate the emote state of each player.
+
+`bool emote.start(player, emotestring)`
+
+Start the named emote for the named player. Returns false if
+the emote is unknown or the emote could not be started. Returns
+true otherwise.
+
+`emote.stop(player)`
+
+Stops any emote for the named player.
+
+`emote.list()`
+
+Lists known emotestring values.
+
+`emote.attach_to_node(player, pos, locked)`
+
+Attach the player to the node at pos. The attachment will be made using the
+parameters provided in the `emote` table in the nodedef:
+```
+nodedef.emote = {
+	emotestring = "sit",
+	eye_offset = {x = 0, y = 0, z = 0},
+	player_offset = {x = 0, y = 1/2, z = 0},
+	look_horizontal_offset = 0,
+}
+```
+
+if `locked` is `true`, then the player is fixed to the node and can only
+move until he presses `jump`. While sitting the player can look around but
+his character does not turn.
+
+The player offset vector will be rotated to account for the node facedir.
+
+## Commands
+
+The emotes are all usable by players using chat commands:
+/lay, /sleep, /sit, /point, /freeze, etc.
+
+## TODO
+
+The API currently only allows unattached emotes (ones where the
+player can just move and cancel the emote). The API needs to
+provide an additional function to allow attached emotes with
+rotation and offset so that players can easily sit on chairs,
+lie on beds or emote-interact with machines (e.g. point emote
+when interacting with a node).
+
+## Can I sit on stair blocks with this?
+
+The patch file `sit-on-stairs.patch` in this project is an example
+patch for minetest_game that will allow a player to right-click stair
+nodes and sit on them as if they were seats.
