u, v

u

v

The pixel offsets of sprite and A7.07 model textures in horizontal and vertical direction. They affect the matTexture texture transformation matrix. By changing these offsets in real time, effects like streaming water can be achieved.

Range:

unlimited (default: 0)

Type:

var

Remarks:

The texture offsets of model or terrain skins can also be changed through the fx_uvspeed action in the MtlFX template script.
On sky domes the u v parameters give the speed of the cloud layers in pixels per tick.

Example:

action water_current // assign to a water sprite
{
	while (1) {
		my.v = 5*total_ticks;
		wait (1);
	}
}
