Summary

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

Examples

<lsl> float cloakSpeed = .1;

default {

   touch_start(integer total_number)
   {
       integer x;
       float xf;
       for (x=9; x>0; x--)
       {
           xf = x * .1;
           llSleep(cloakSpeed);
           llSetAlpha(xf,ALL_SIDES);      
       }
       state cloaked;
   }

}

state cloaked {

   touch_start(integer total_number)
   {
       integer x;
       float xf;
       for (x=1; x<11; x++)
       {
           xf = x * .1;
           llSleep(cloakSpeed);
           llSetAlpha(xf,ALL_SIDES);  
       }
       state default;
   }

}

</lsl>
