*cough* BULLSHIT *cough*
You fucking text book deficient. Do you EVER TRY any of the fucking
bullshit you pull out of yer ass?
Here's a live example using YOUR fuckwitted version:
http://www.backwater-productions.net/_test_platform/Sprite_Test/index.php
....huh. So, not only does your method not work AT ALL...unless a
plain black screen was what you were aiming for, but it took FOUR
HUNDRED AND SEVENTY SEVEN SECONDS to produce it.
Now here's MY method:
http://www.backwater-productions.net/RMXP_CSG/index.php
....huh. Now, granted, I do need to fix it with the zero reds so as
not to produce an image like this:
http://www.backwater-productions.net/_images/_Usenet/Failed_Color.png
However, my version not only does more than produce a PLAIN BLACK
SCREEN, but amazingly enough, it only takes NINETEEN SECONDS to
render.
DUM DUM DUM DUM DUM...you sure are a fuckwitted lil retard, aren'tcha
Jeckyl?
Here's those numbers again (for the benefit of the slower children):
My way ~ 19 seconds
Your way ~ 477 seconds
That basically means that your way isn't 700 times slower, it's TWO
THOUSAND FIVE FUCKING HUNDRED TIMES SLOWER...you dribbling retard.
And once again, all you've done is RUN THE FUCK AT THE MOUTH...where
as I've put up LIVE EXAMPLES of the two methods and anyone who wants
to confirm your stupidity can simply look at the source code to
confirm it.
