Pixel Functions Usage

[Guest rathore]

i've never coded an autoit script for games... but just to know how this all works, i tried the simplest way i cud think of.

AutoItSetOption("PixelCoordMode", 0) ;i've tried commenting this option too
While 1
sleep (10)
$pix=PixelGetColor(317,99) ;running in 640*480
if $pix = 60160 then Send("{ins}") 
WEnd

this does nothing but in NFSUnderground Drag mode presses gear up button when there's a green light for that. but this doesn't work... & i don't know why!... i've taken the values from a screenshot.

my concern here is mainly getting an idea of the working of these scripts... i've no plans to make any complex use of this...

can somebody enlighten me plz?!

try this:

AutoItSetOption("PixelCoordMode", 0);i've tried commenting this option too
While 1
sleep (10)
$pix=PixelGetColor(317,99);running in 640*480
if $pix = 60160 then Send("{ins}")
tooltip($pix,0,0); this will show you what color it sees constantly.
WEnd

Your pixel value might be a bit off due to gamma in the game as well,

thanx for telling this to me, didn't know that it'd matter... now i've changed the script to..

AutoItSetOption("PixelCoordMode", 0)
While 1
sleep (10)
$pix=PixelGetColor(317,99)
if $pix > 40000 AND $pix < 65000 then
   Send("{ins}")
   sleep (750); so that it doesn't change gear twice
endif
WEnd

it works... but not always... rather bout 25% of the times only!.. i even raised the priority of au3 but that didn't help either! what cud b the cause?
