What goes wrong ?

[Markus1971]

I am near to brain collaps....

Ok, here is what i try :

I have a Pixelsearch on a little part of the screen. This Pixels can be red or green.
As long as i detect red or green pixels in this area everything is OK.

But when nither red or green is found i want to execute a function.

This is what i tryed :
 

expandcollapse popup

Global $iTellme = 1

While 1
    reader()
    Alert()
    $nMsg = GUIGetMsg()

    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd




Func reader()
    $ColVarread = GUICtrlRead($ColVar)
    $iSearchpoint = GUICtrlRead($Eper)
    $aEcoord = PixelSearch(465, $iSearchpoint, 468, $iSearchpoint + 1, 0xFF2020, 200)
        If IsArray($aEcoord) = True Then
        GUICtrlSetBkColor($List1, 0xFF2020)
        GUICtrlSetData($List1, "")
        GUICtrlSetData($List1, "Red")
        ConsoleWrite("Red found" & @CRLF)
        $iTellme = 0

        Else
    $aEcoord = PixelSearch(465, $iSearchpoint, 468, $iSearchpoint + 1, 0x20FF20, 200)
        If IsArray($aEcoord) = True Then
        GUICtrlSetBkColor($List1, 0x20FF20)
        GUICtrlSetData($List1, "")
        GUICtrlSetData($List1, "Green")
        ConsoleWrite("Green found" & @CRLF)
        $iTellme = 0

    EndIf

 EndIf
EndFunc


Func Alert()
    If $iTellme = 1 Then
    GUICtrlSetData($List1, "")
    GUICtrlSetData($List1, "ALARM")
    Send ("A")
    Sleep(1500)
    EndIf
    

EndFunc

So far my thoughts....
The $iTellme is set global to 1.
As long as i find red or green pixels in the area everything is fine and $iTellme will be set to 0 and the function Alert will do nothing.
But if no red or green pixels are found, $iTellme will stay 1 and  the Function Alert will do its job...

But o have no idea why all this is not working at all. Sometimes Alert is executed no matter what or, when i try something else, it is not executed at all....
Where is my error ?

You set the Global variable $iTellme to 0 whenever one is found but never set it to 1 again.    so what about you do that before your color tests?

Hi Jos, that was my attemp #102.....
I set the Var to 1 again right at the end of the Alarm-Func .... and then i had the weired problem that the routine got stuck at the reader function and the prog stopped working...

believe me... i tryed so many variants like Chase, Select etc....
Maybe my next try will be to do a function for every single Pixelsearch, set Vars and at the end look up the Vars and execute functions according.
