Hello, this is my first time posting in forum yet I was trying to make a game with autoit and this is my code.

How can I understand what button just hitted ? I saw checkers post by someone in forum but I couldnt understand it.

(15) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
Case $idMsg = $button[$i][$j]
Case $idMsg = ^ ERROR

What do you think the values of $i and $j are at that point?

$i = 0 to 7 and $j = 0 to 7

Don't think so as you can see in a Tidied version:

#include <GUIConstantsEx.au3>
AutoItSetOption("MustDeclareVars", 0)
Global $idMsg, $button[8][8], $i, $j
Local $gui = GUICreate("Board Game", 700, 700)
GUISetState(@SW_SHOW)
GUISetOnEvent($GUI_EVENT_CLOSE, "Exitt")
For $i = 0 To 7
    For $j = 0 To 7
        $button[$i][$j] = GUICtrlCreateButton("", 448 - 56 * $i, 448 - 56 * $j, 56, 56)
    Next
Next
While 1
    $idMsg = GUIGetMsg()
    Select
        Case $idMsg = $button[$i][$j]
            GUICtrlSetState($msg, 128)
        Case $idMsg = $GUI_EVENT_CLOSE
            Exit 0
    EndSelect
    Sleep(10)
WEnd

So my guess is they are both set to 8.....

This posted script has other errors too.

how can i solve it like I don't want to put 64 diffrent cases there how can I use something like this ?

You will have to do the same 2 for..next loops in the while loop.

[Dan_555]

Simply loop through the array in this way:

$idMsg = GUIGetMsg()

For $i = 0 To 7
    For $j = 0 To 7
        if $idMsg=$button[$i][$j] then 
            ConsoleWrite("button pressed" & @crlf)
            ExitLoop 2
        EndIf
    Next
Next
