Summary

Function: llSetAlpha( float alpha, integer face );
51 Function ID
0.0 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.

            xf = x * .1;
            llSleep(cloakSpeed);

Notes

In practical terms, "alpha" means "transparency" or "visibility".

To be clear, llSetAlpha will only affect the prim that the script it is in. It will not affect any linked prims. To set the alpha state for those, use llSetLinkAlpha
