Trouble With Multi-color PixelSearch

4 posts in this topic

Hello all,

I've run in to a problem that I'm sure I'm overlooking a simple solution to.

I'm trying to PixelSearch for a couple of colors and if either of them is found execute a bit of code and I've got this part working no problem.

Local $colors[2] = [ 0xB0BDCC, 0x899BCD ]

For $i = 0 to 1
    $b = PixelSearch(161, 298, 324, 321, $colors[$i], 20, 1)
    If IsArray($b) Then
        _Func1
    EndIf
Next

However, the trouble I run in to is that I need to execute another bit of code if neither of the two colors is found.

Local $colors[2] = [ 0xB0BDCC, 0x899BCD ]

For $i = 0 to 1
    $b = PixelSearch(161, 298, 324, 321, $colors[$i], 20, 1)
    If IsArray($b) Then
        _Func1()
    Else
        _Func2()
    EndIf
Next

The problem being that if the first color in my array isn't found it immediately executes _Func2() rather than searching for the second color first.

I understand that as my code is written it's actually doing what I'm telling it to do, but I'm a bit unsure on how to fix my code to have it perform as I intend.

Thanks in advance for any help provided.

inter,

I would do it like this: :)

Local $colors[2] = [ 0xB0BDCC, 0x899BCD ]

; Clear flag
Local $fFlag = 0

; Run double search
For $i = 0 To 1
    $b = PixelSearch(161, 298, 324, 321, $colors[$i], 20, 1)
    ; If found then set flag
    If IsArray($b) Then $fFlag += 1
Next

; Now check flag
If $fFlag Then
    ; Flag was set at least once
    _Func1()
Else
    ; Flag was not set
    _Func2()
EndIf

There are many other ways, but I quite like flags! :)

Another way is this :

Local $colors[2] = [ 0xB0BDCC, 0x899BCD ]

#include "fastfind.au3"

FFAddColor($colors)

$b = FFNearestPixel(161, 298, 324, 321, 0, 0, -1)
If IsArray($b) Then
      _Func1()
Else
      _Func2()
EndIf

Thank you both for your suggestions.

Melba, I'm not sure how I get lucky to have you respond to my threads first, but you've always been able to get exactly what I need. Many thanks!
