AutoIT non-array variable?

[Kidney]

Error i get when running my code:

"Line 854 (File "C:\Users\Jon\Documents\PixelClick.exe"):

Error: Subscript use with non-Array Variable."

Func BuyTwo()
MouseClick("left", 435, 18, 1, 0)
Sleep(100)
$Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0)
MouseClick( "Left", $Buy[0]+5, $Buy[1]+5, 1, 0)
Sleep(100)
MouseClick("left", 695, 18, 1, 0)
Sleep(100)
$Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0)
MouseClick( "Left", $Buy[0]+5, $Buy[1]+5, 1, 0)
EndFunc

In your case $Buy is no array. Check for errors after each PixelSearch.

In your case $Buy is no array. Check for errors after each PixelSearch.

well the thing is, it works half the time and the other half it doesnt. if it doesnt find a pixel with the specific color, will it give me that error??

Yes, it sets @error and doesn't return an array, when no pixel is found.

I suggest you read the help file. All info can be found there.

alright i got it working. just added a couple of error proofing steps that probably make it look a little sloppy but it gets the job done.

final code:

Func BuyTwo()
    $Buy = 0
    MouseClick("left", 435, 18, 1, 0) ;Tab 1
    Sleep(100)
    $Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0, 2) ;Look for the buy button
    Sleep(100)
    While $Buy = 0 ;Re-search for the buy button if not found the first time
        $Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0, 2)
        Sleep(100)
    WEnd
    MouseClick( "Left", $Buy[0]+5, $Buy[1]+5, 1, 0) ;Click the buy button
    $Buy = 0
    Sleep(100)
    MouseClick("left", 695, 18, 1, 0) ;Tab 2
    Sleep(100)
    $Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0, 2) ;Look for the buy button
    Sleep(100)
    While $Buy = 0 ;Re-search for the buy button if not found the first time
        $Buy = PixelSearch( 1410, 450, 1540, 495, 0xF0F0F0, 2)
        Sleep(100)
    WEnd
    MouseClick( "Left", $Buy[0]+5, $Buy[1]+5, 1, 0) ;Click the buy  button
    Sleep(100)
    MouseClick("left", 200, 18, 1, 0) ;Home Tab
    MouseMove(875, 850, 0) ;Move closer to "I have them all"
EndFunc
