comparing lists of colors

[neverlevel]

So i am reading a line of colors and saving them to a file i need to be able to tell which pixel locations have changed colors.

Code: Select all

sx = 900
sy = 727

Loop, 
{
pixelgetcolor, Canplay, %sx%,%sy%
sx-=1
Fileappend, %canplay%, search.txt
if sx < 200
break
}
msgbox, done

I need to know which X locations have changed . the color around usable objects pulses and is semi transparent so i cant just search for a specific color. there could be up to 20 matches im hoping to be able to catch the color change
