PositionTexture:Void texture:Int32, u_offset:Float32, v_offset:Float32

Parameter	Mode	Type	Default	Description
texture	In	Int32	required	The texture to move.
u_offset	In	Float32	required
v_offset	In	Float32	required

Description

Moves the texture coordinates by an absolute offset. The image appears to slide across the surface, which is how scrolling water or conveyor belts are done. The offset is a fraction of the texture: 1 moves it by one full repeat, which looks the same as 0. Every entity that uses the texture changes at once.
