SetAlpha

llSetAlpha

Summary

Function: llSetAlpha( float alpha, integer face );

51	Function ID
0.0	Forced Delay
10.0	Energy

Sets the alpha on face

• float	alpha	–	from 0.0 (clear) to 1.0 (solid) (0.0 <= alpha <= 1.0)
• integer	face	–	face number or ALL_SIDES

If face is ALL_SIDES then the function works on all sides.

Caveats

• The function silently fails if its face value indicates a face that does not exist.
