node. It is called "node metadata"; See "`NodeMetaRef`".
Metadata contains two things:
+
* A key-value store
* An inventory
Some of the values in the key-value store are handled specially:
+
* `formspec`: Defines a right-click inventory menu. See "Formspec".
* `infotext`: Text shown on the screen when the node is pointed at
* `set_properties(object property table)`
* `get_properties()`: returns object property table
* `is_player()`: returns true for players, false otherwise
+* `get_nametag_attributes()`
+ * returns a table with the attributes of the nametag of an object
+ * {
+ color = {a=0..255, r=0..255, g=0..255, b=0..255},
+ text = "",
+ }
+* `set_nametag_attributes(attributes)`
+ * sets the attributes of the nametag of an object
+ * `attributes`:
+ {
+ color = ColorSpec,
+ text = "My Nametag",
+ }
##### LuaEntitySAO-only (no-op for other objects)
* `setvelocity({x=num, y=num, z=num})`
* in first person view
* in third person view (max. values `{x=-10/10,y=-10,15,z=-5/5}`)
* `get_eye_offset()`: returns offset_first and offset_third
-* `get_nametag_attributes()`
- * returns a table with the attributes of the nametag of the player
- * {
- color = {a=0..255, r=0..255, g=0..255, b=0..255},
- }
-* `set_nametag_attributes(attributes)`
- * sets the attributes of the nametag of the player
- * `attributes`:
- {
- color = ColorSpec,
- }
### `InvRef`
An `InvRef` is a reference to an inventory.
Inside of `on_generated()` callbacks, it is possible to retrieve the same VoxelManip object used by the
core's Map Generator (commonly abbreviated Mapgen). Most of the rules previously described still apply
but with a few differences:
+
* The Mapgen VoxelManip object is retrieved using: `minetest.get_mapgen_object("voxelmanip")`
* This VoxelManip object already has the region of map just generated loaded into it; it's not necessary
to call `VoxelManip:read_from_map()` before using a Mapgen VoxelManip.
* `update_map()`: Update map after writing chunk back to map.
* To be used only by `VoxelManip` objects created by the mod itself;
not a `VoxelManip` that was retrieved from `minetest.get_mapgen_object`
-* `set_lighting(light, p1, p2)`: Set the lighting within the `VoxelManip` to a uniform value
+* `set_lighting(light, [p1, p2])`: Set the lighting within the `VoxelManip` to a uniform value
* `light` is a table, `{day=<0...15>, night=<0...15>}`
* To be used only by a `VoxelManip` object from `minetest.get_mapgen_object`
* (`p1`, `p2`) is the area in which lighting is set;
* expects lighting data in the same format that `get_light_data()` returns
* `get_param2_data()`: Gets the raw `param2` data read into the `VoxelManip` object
* `set_param2_data(param2_data)`: Sets the `param2` contents of each node in the `VoxelManip`
-* `calc_lighting(p1, p2)`: Calculate lighting within the `VoxelManip`
+* `calc_lighting([p1, p2], [propagate_shadow])`: Calculate lighting within the `VoxelManip`
* To be used only by a `VoxelManip` object from `minetest.get_mapgen_object`
* (`p1`, `p2`) is the area in which lighting is set; defaults to the whole area
- if left out
+ if left out or nil
+ * `propagate_shadow` is an optional boolean deciding whether shadows in a generated
+ mapchunk above are propagated down into the mapchunk; defaults to `true` if left out
* `update_liquids()`: Update liquid flow
* `was_modified()`: Returns `true` or `false` if the data in the voxel manipulator
had been modified since the last read from map, due to a call to
stepheight = 0,
automatic_face_movement_dir = 0.0,
-- ^ automatically set yaw to movement direction; offset in degrees; false to disable
+ automatic_face_movement_max_rotation_per_sec = -1,
+ -- ^ limit automatic rotation to this value in degrees per second. values < 0 no limit
backface_culling = true, -- false to disable backface_culling for model
+ nametag = "", -- by default empty, for players their name is shown if empty
+ nametag_color = <color>, -- sets color of nametag as ColorSpec
}
