/*QUAKED infodecal (1 0 0) (-8 -8 -8) (8 8 8)
|
|
Projects a decals.wad texture onto the nearest surface.
|
|
It'll automatically figure out the surface based on distance.
|
|
The texture will be aligned along the surface texture normals.
|
|
|
|
-------- KEYS --------
|
|
"targetname" : Name
|
|
"texture" : Name of the texture inside decals.wad it projects onto a surface.
|
|
|
|
-------- NOTES --------
|
|
This entity currently only works on BSP version 30 levels.
|
|
|
|
If a targetname is supplied, it will have to be triggered by an entity in order
|
|
to appear. Afterwards it cannot be triggered again.
|
|
|
|
It will pick the nearest wall (currently checking a distance of 128 units,
|
|
which is probably overkill). No angle has to be supplied.
|
|
|
|
-------- TRIVIA --------
|
|
This entity was introduced in Half-Life (1998).
