Summary
Function: float llGetAlpha( integer face );50 | Function ID |
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 returns the sum of alpha of all the faces on the prim. The return is in the range [0, 1] times the number of sides requested.
Caveats
- If face indicates a face that does not exist the return is 0.0
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>
Useful Snippets
<lsl>float AveragePrimAlpha() {//Since this is so simple you may just want to inline it instead of including the function.
return (llGetAlpha(ALL_SIDES) / llGetNumberOfSides());
}</lsl>
