Summary

Function: float llGetAlpha( integer face );
0.0 Forced Delay
10.0 Energy

Returns a float that is the alpha of face.

• integer face face number or ALL_SIDES

If face is ALL_SIDES then the function works on all sides. The return is in the range [0, 1]

Caveats

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

Examples

<lsl>//Tells the owner the alpha on all sides default {

   state_entry()
   {
       integer i = 0;
       integer max = llGetNumberOfSides();
       while(i < max)
       {
           llSay(0,"Face "+(string)i+" alpha is " + (string)llGetAlpha(i));
           ++i;
       }
   }
}</lsl>
