I have a logic problem I cannot figure out

[computergroove 32]

I have 4 vnc windows next to each other. If one of the screens goes black (remote device goes into standby) I want to right click it if the screen is totally black for 10 seconds to wake it up. When I start it with the 4th vnc window blacked out the tooltip displays 0,0,0,0 to 0,0,0,1 and stays there. The vnc screens are 320 pixels wide and are lined up next to each other. Any help?

You did not explain your problem with script.

[Blinky 7]

your script should work, maybe the pixels you search are  blackish

any way here is a more compresed version, I tested it with a black picture and it works

Global $Number = 4
Global $timer[$Number]

For $i=0 to $Number-1
    $timer[$i] = 0
Next

While 1
     BlackScreen()
     Sleep(200)
WEnd

Func BlackScreen($x1=21,$x2=28,$x3=254,$x4=258)
    For $i = 0 To $Number -1
        If PixelGetColor($x1+320*$i,72)=0 Then
            If PixelGetColor($x2+320*$i,72)=0 Then
                If PixelGetColor($x3+320*$i,426)=0 Then
                    If PixelGetColor($x4+320*$i,434)=0 Then
                        If $timer[$i]=0 Then $timer[$i]=TimerInit()
                    EndIf
                EndIf
            EndIf
        Else
            $timer[$i] = 0
        EndIf
        If $timer[$i]<>0 and TimerDiff($timer[$i]) >= 10000 Then
            MouseClick("Right",21+320*$i,72)
            $timer[$i] = 0
        EndIf
    Next
EndFunc
