==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'''

|<source lang="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;
}
}
}
</source>
|}
 
'''Useful Snippets''' 
{|border="1" cellpadding="5" cellspacing="0"
|<source lang="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());
}
</source>
