C-Script: vec_for_uv

vec_for_uv (VECTOR, ENTITY, var number);
vec_to_uv (VECTOR, ENTITY, var number);

Modifies the skin texture position of a certain model vertex. vec_for_uv sets VECTOR to the texture uv coordinates of the given vertex number; vec_to_uv sets the texture to new uv coordinates given by VECTOR.

Parameters:

VECTOR*	uv skin coordinates in x and y. The z component is ignored.
ENTITY*	entity pointer
number	number of the mesh vertex in the MED status line

Modifies:

VECTOR* - set to a uv skin coordinate by vec_for_mesh.

Speed:

Medium

Remarks:

These functions don't support map entities, sprites, or chunked terrain, and are replaced by ent_getvertex/ent_setvertex that should be used for new projects.
Modifying a mesh of a certain entity affects all entities that use the same mesh.
Modifying skin texture coordinates of a certain entity affects all entities that use the same mesh.
Skin coordinates are not automatically saved by game_save(). If this is desired, store the mesh coordinates in an array.

Example:

function shiftskin(ent,num) // displace the skin position of a vertex
{
	vec_for_uv(temp,ent,num);
 	temp.x += 1; // move the skin coordinate by 1 pixel horizontally
 	vec_to_uv(temp,ent,num);
}
