How to make a loop which will end when a certain color appears on an area of the screen?

4 posts in this topic

Hello. It's the first time that I post here and I got a question (was searching for something similiar on the forums but couldn't find it). The exact thing which I need is a "do" loop which will be executed until a certain color appears on a certain area of the screen. I was thinking on something like:

Do
       ...
Until PixelSearch (...)

, but it always ends up being an endless loop. Sorry if that was a stupid question, I'm kinda new to AutoIt, but I know the basics. Please keep the answers as simple as possible, thanks in advance.

Edit: ye I also got endless loop after I quit the script for a moment. must be a new♠ bug. worked fine next time I run it tho.

While   1

    Sleep(500)

    $var = PixelGetColor( 10 , 100 ) ; position x & y axis on the screen
    $var = Hex($var, 6)

    ConsoleWrite($var & @CRLF)

    If $var = 'FFFFFF' then ExitLoop

WEnd

Edit2:

there is a UDF,I dont remember who made it cuz he did not include that information, but its great if u want to choose a color: I think its called FLEXY

#Include <Misc.au3>

Your code causes undefined behaviour. Read the help on PixelSearch, it doesn't actually say what it returns if the pixel is not found. Any time that a function sets @error, the result should be treated as undefined, you must check @error before using the return value of PixelSearch. So you can't use PixelSearch as a logical function to use in a condition such as a loop terminator.

This should do as a quick fix...

Do
       ...
       PixelSearch (...)
Until Not( @error )

but I'd prefer to write a wrapper, maybe call it _PixelFound() or something like that, that does PixelSearch and returns True if the pixel is found.
