    resolved [RESOLVED] My array gets reset

    This is probably a very newbie question
    Here is my script. Why does groupArray gets reset each time the function addTest is called?
    I want it not to reset.

    Code:
    var groupArray:Array = new Array([],[]);
    stage.addEventListener(MouseEvent.MOUSE_DOWN, addTest);
    function addTest(event:MouseEvent) {
    	groupSelected = 0;
    	groupArray[groupSelected].push("item");
    	groupArray[groupSelected].push("item2");
    	trace("New lenght: "+groupArray[groupSelected].length); // returns 2 each time addTest is called
    }
    returns 2 each time addTest is called


    Similar I could have:
    Code:
    var testVariable:Boolean = false;
    stage.addEventListener(MouseEvent.MOUSE_DOWN, addTest);
    function addTest(event:MouseEvent) {
    	trace (testVariable); // returns false each time function is called
    	testVariable = true
    }
    returns false each time function is called

    But if I say:
    Code:
    var testVariable:Boolean;
    stage.addEventListener(MouseEvent.MOUSE_DOWN, addTest);
    function addTest(event:MouseEvent) {
    	trace (testVariable); // returns false first time, but then returns true
    	testVariable = true;
    }
    returns false first time, then true.


    How do I declare an multidimensional array that does not get reset? Sorry for long explanation.

    Put a trace statement outside your function. It looks like your frame script is being run multiple times.

    Yes it is an frame script.
    Copied the trace outside the function, now it works. What a strange behavior!
    Is this another reason why one should "never" use framescripts, but classes instead?

    That's... Not what I said. I wanted you to put another trace, outside the function, to see if it got executed more than once. If it did, then your frame script was being executed more than once, and it would reset your variables each time.

    resolved

    I restarted flash, and now it seems to give a more reliable response.
