Question

Answer 1

+1 A:

Your e.target should work, though you don't (as far as I can see) need the [_"white"] after e.target for your _white buttons. The reason the e.targets aren't working is because you're just adding event listeners to the stage, and not the individual buttons.

I see two choices (perhaps there are others): manually go through writing event listeners for each button, or put all the buttons that will use the overEffect function into one Array, and all the buttons using the outEffect function into another Array.

Then create two for loops, and go through those Arrays adding the event listeners to each child of the array. Your e.target code should work at that point.

Let me know if you have any trouble with that, hope it helps.

I agree with this, but really, I recommend just adding event listeners to each button. There are only 10 buttons, so it's really unnecessary to make it any more complicated. Do it very much like your first code block Meko, buttonname.addEventListener etc...

Yeah I agree, it's probably overkill to use Arrays for this number of objects. Becomes more concise if you're using a lot more than 10 though.

Hi,

Here is a quick example that may help you:

function createButton():MovieClip{
    var button:MovieClip=new MovieClip();
    var stateA:Shape=new Shape();
    var g:Graphics = stateA.graphics;
    g.beginFill(0xFF0000);
    g.drawRect(0, 0, 10, 10);
    g.endFill();
    button["stateA"] = stateA;
    button.addChild(stateA);
    var stateB:Shape=new Shape();
    g = stateB.graphics;
    g.beginFill(0x00FF00);
    g.drawRect(0, 0, 10, 10);
    g.endFill();
    button["stateB"] = stateB;
    button.addChild(stateB);
    stateB.visible=false;
    return button;
}
var nbButtons:int=10;
var buttons:Array=[];
var selectButton:MovieClip;
for (var i : int = 0;i < nbButtons; i++) {
    var button:MovieClip=createButton();
    addChild(button);
    button.y=10;
    button.x=i*12+10;
    addChild(button);
    buttons.push(button);
    setUpButton(button);
}
function setUpButton(button:MovieClip):void {
    button.buttonMode=true;
    button.addEventListener(MouseEvent.ROLL_OVER, buttonRollOver);
    button.addEventListener(MouseEvent.ROLL_OUT, buttonRollOut);
    button.addEventListener(MouseEvent.CLICK, buttonClick);
}
function buttonClick(e:Event):void{
    switchButtonStateToNotSelected();
    switchButtonStateToSelected(e.currentTarget as MovieClip);
}
function switchButtonStateToSelected(button:MovieClip):void{
    button.buttonMode=true;
    button.removeEventListener(MouseEvent.ROLL_OVER, buttonRollOver);
    button.removeEventListener(MouseEvent.ROLL_OUT, buttonRollOut);
    button.removeEventListener(MouseEvent.CLICK, buttonClick);
    button["stateA"]["visible"]=false;
    button["stateB"]["visible"]=true;
    selectButton=button;
}
function switchButtonStateToNotSelected():void{
    if(selectButton) {
        setUpButton(selectButton);
        selectButton["stateA"]["visible"]=true;
        selectButton["stateB"]["visible"]=false;
        selectButton=null;
    }
}
function buttonRollOver(e:Event):void{
    e.currentTarget["stateA"]["visible"]=false;
    e.currentTarget["stateB"]["visible"]=true;
}
function buttonRollOut(e:Event):void{
    e.currentTarget["stateA"]["visible"]=true;
    e.currentTarget["stateB"]["visible"]=false;
}
