help with array variable

[Burgaud]

Hi

I am new to AutoIt and this is my problem:

func ScanPick ($color,$timeout,$x)
    Local $aCoord[2]
    $aCoord = PixelSearch(660,180,1260,780, $color, 2)
    Wait(100)
    print(stringformat("%d %d",$aCoord[0], $aCoord[1]))
    if Not @error then
        MouseClick("left", $aCoord[0], $aCoord[1])
        print(StringFormat("Looting Item [%d]",$x+1))
        Wait($timeout)
        return(1)
    else
        return(0);
    endif
endfunc

I could not get it to access $aCoord[0], $aCoord[1]

I keep getting:

Error: Subscript used on non-accessible variable on the Print; what gives?

Same problem with the MouseClick statement, I simply could not access $aCoord[0] with the error indicating "[" as error???

Need help

Burgaud,

It sounds as if the PixelSearch function is not returning an array - I suggest you do some error-checking (with IsArray) before trying to access the array elements.

Welcome to the Forum

I believe this should be correct!

func ScanPick ($color,$timeout,$x)
    Local $aCoord[2]
    $aCoord = PixelSearch(660,180,1260,780, $color, 2)
    Wait(100)
    if IsArray($aCoord) Then
        print(stringformat("%d %d",$aCoord[0], $aCoord[1]))
            MouseClick("left", $aCoord[0], $aCoord[1])
            print(StringFormat("Looting Item [%d]",$x+1))
            Wait($timeout)
            return(1)
    else
        ConsoleWrite(@error & @LF)
        return(0);
    EndIf
endfunc

Got it!

I was relying so much on Not

if Not @error then

But it appears it is not working

Thanks!

PS. Loving AutoIT!

@error works just fine but I suspect you're testing it in the wrong place.

@error is set to 0 upon entering all functions including those you define yourself.
