IntToRGBA(Number, &Red, &Green, &Blue, &Alpha); by kyoshiro aka kyosaur

What is this?

This define is the inverse to THIS. It takes a color and returns its RGBA values. Its probably not as useful as the RGBAToInt function, but i decided to make it anyways for shits and giggles. Once again i made multiple versions and ran speed tests, the results are at the bottom.


Note: This can not be used inside of an if statement. I have no idea why someone would want to put it in one, i just thought i would say so for the n00bs.


Code (for those who dont care about the tests):

pawn Код:

#define IntToRGBA(%0,%1,%2,%3,%4) \
(%1) = ((%0) >>> 24); (%2) = (((%0) >>> 16) & 0xFF); (%3) = (((%0) >>> 8) & 0xFF); (%4) = ((%0) & 0xFF)

Speed results (10,000,000 loops)

Unfortunately i couldnt think of a way to break it down any further. If anyone can think of an improvement or another method, im all ears.
