Pixelchecksum problem

[DareDev1l]

Hi. I got problem with pixelchecksum. I want to make a script , in which when the pixel right in the center of the screen changes , to execute a command. Here is my script but it doesn't work :S

HotKeySet("{F2}" , "Sendcode")

While 1
sleep(100)
Wend

Func Sendcode()
Local $Pixel = PixelCheckSum(@DesktopWidth/2 - 1 , @DesktopHeight/2 + 1, @DesktopWidth/2 + 1, @DesktopHeight/2 - 1)

While $Pixel = PixelCheckSum(@DesktopWidth/2 - 1 , @DesktopHeight/2 + 1, @DesktopWidth/2 + 1, @DesktopHeight/2 - 1)
sleep(1)
WEnd

Send("first")

EndFunc

your script do work, didnt you forgot to press F2?

similar (alternative) way

$pixel = PixelGetColor()
Do
    Sleep(10)
Until $pixel <> PixelGetColor()
