Question

I have 4 movieclips in an array

var tiles:Array = new Array("tile1","tile2","tile3","tile4");

Inside each one there is code to vanish when it's clicked with the mouse on the second frame.

this.visible = false;

From the main timeline is the control for the mouse click for each of the tiles (only the first one is displayed).

tile1.addEventListener(MouseEvent.CLICK, fl_);

function fl_(event:MouseEvent):void
{
    tile1.gotoAndStop(2);
}

How can I make it so when all the tiles in the array become invisible, flash to take action (such as to go to frame 5)?

Thank you!

I've looked at your .fla. Here are two ways to do what you'd like:

On Your Main Timeline: (replace the current main timeline frame 1 code with the following)

stop(); 

//loop through every child of the `cont` container, and add the same click listener
var i:int = cont.numChildren
while(i--){
    var tile:MovieClip = cont.getChildAt(i) as MovieClip;
    if(tile){
       tile.addEventListener(MouseEvent.CLICK, tileClick, false,0,true);
    }
}

function tileClick(e:MouseEvent):void {
    //this gets a reference to one that was clicked
    var tile:MovieClip = e.currentTarget as MovieClip;

    tile.gotoAndStop(2);

    //loop through the tile array to see if any are still visible
    var i:int = cont.numChildren
    while(i--){
        tile = cont.getChildAt(i) as MovieClip;
        if(tile && tile.currentFrame == 1) return;
    }

    //if we got this far, all the tiles are hidden, lets go to frame 5.
    gotoAndStop(5);
}

---

If the above is intimidating and you would prefer to keep it like it was before, then this is all you'd have to do: (again, this code will replace your current main timeline frame 1 code)

stop();

cont.tile1.addEventListener(MouseEvent.CLICK, tileClick);
cont.tile2.addEventListener(MouseEvent.CLICK, tileClick);
cont.tile3.addEventListener(MouseEvent.CLICK, tileClick);
cont.tile4.addEventListener(MouseEvent.CLICK, tileClick);

function tileClick(e:MouseEvent):void {
    MovieClip(e.currentTarget).gotoAndStop(2);
    if(cont.tile1.currentFrame == 1) return;
    if(cont.tile2.currentFrame == 1) return;
    if(cont.tile3.currentFrame == 1) return;
    if(cont.tile4.currentFrame == 1) return;

    //if we got this far, all the tiles are hidden, lets go to frame 5.
    gotoAndStop(5);
}
