LlGetAlpha

Function: float llGetAlpha( integer face );

Returns a float that is the alpha of face.
• integer face – face number or ALL_SIDES

If face is ALL_SIDES then the function returns the sum of alpha of all the faces on the prim.
The return is in the range [0, 1]

Caveats
• If face indicates a face that does not exist the return is 0.0

Examples

//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;
       }
   }

} </source>

Useful Snippets

float AveragePrimAlpha() {//Since this is so simple you may just want to inline it instead of including the function.

   return (llGetAlpha(ALL_SIDES) / llGetNumberOfSides());

} </source>
