[mod] visible wielded items [wieldview]
|
||||
=======================================
|
||||
|
||||
Depends on: 3d_armor
|
||||
|
||||
Makes hand wielded items visible to other players.
|
||||
|
||||
default settings: [minetest.conf]
|
||||
|
||||
# Set number of seconds between visible wielded item updates.
|
||||
wieldview_update_time = 2
|
||||
|
||||
# Show nodes as tiles, disabled by default
|
||||
wieldview_node_tiles = false
|
||||

||||

||||
Info for modders

################
|
||||
|
||||
Wield image transformation: To apply a simple transformation to the item in
|
||||
hand, add the group “wieldview_transform” to the item definition. The group
|
||||
rating equals one of the numbers used for the [transform texture modifier
|
||||
of the Lua API.
|
||||
|
||||
Disabling the feature in-game: If you want to hide the wielded item
|
||||
you can add an INT metadata to the player called "show_wielded_item" and set
|
||||
it to 2 (any other value will show the wielded item again).
