Need help to wait for a pixel color to change Topic is solved

[marc873a]

Hi.
I tried to wrote a code to check for one pixel has the right color:

Code: Select all

Pxc1 = 0

Numpad1::
Loop {
PixelGetColor, Pxc1, 906, 284
if (%Pxc1% = 0xB0FEFF)
{
Msgbox, Pixel is now at the right color
Break
}
}
return

It doesn't work.
Plz explain if you do something sophisticated as I am kinda new to AHK.
Thanks

No % symbols around Pxc1 in the if statement. Also, if 0xB0FEFF is in RGB format (as opposed to BGR), then you need to specify the RGB option in the PixelGetColor command. Or you could specify the color as 0xFFFEB0.

Code: Select all

Numpad1::
Pxc1 = 0

Loop {
	PixelGetColor, Pxc1, 906, 284, RGB

	;if Pxc1% = 0xB0FEFF
    	if Pxc1 = 0xFF0000
		{
		Msgbox, 4096, , Pixel is now at the right color
		Break
		}
}
return

This works. I have used pure red (FF0000) because I think it's a good way to test the script. Your colour is commented out here.
That's how I found out I have to put 'RGB' in the PixelGetColor code. Because if it was BGR (default) my FF0000 would be pure blue.

I also suggest to look at your coordinates for the pixel, because default it's in the Active Window. Use Window Spy or the command MouseGetPos to find your exact x and y.

I don't know why (also a beginner) the MsgBox in your code was only very shortly visible and it dissapeared to the background.
MsgBox option 4096 is to keep it on top.
