Question

I’ve got the following code and i would like to add an delay of 200 ms after each trace statement

for (var x_pos:uint = 0; x_pos <= 12; x_pos++){ 
    for (var y_pos:uint = 0; y_pos <=12; y_pos++){
        trace("hello world " +"("x_pos+","+y_pos+")");
        //CODE FOR DELAY OF 200ms    
    }
}

The real situation is a bit more complex but kind of the same:

//For each Row 
for (var x_pos:uint = 0; x_pos <= tile_amount-1; x_pos++){
    //For each column 
    for (var y_pos:uint = 0; y_pos <= tile_amount-1; y_pos++){
        //New tile;
        var newtile:Tile = new Tile;

        //Set position
        newtile.x = ((40*y_pos)-(40*x_pos));
        newtile.y = ((20*y_pos)+(20*x_pos));

        //Add to stage 
        addChild(newtile);
    }
}

Anyone any suggestions ?

You can’t stop the execution of code in the middle of a statement like that, your best bet is to use a timer:

package 
{
    import flash.events.TimerEvent;

    public class Foo
    {

        private var x_pos:uint = 0;
        private var y_pos:uint = 0;
        private var timer:Timer;

        public function Foo()
        {
            timer = new Timer(200, 0);
            timer.addEventListener(TimerEvent.TIMER, handleTick);
            timer.start();
        }


        public function handleTick(e:TimerEvent):void {

            trace("hello world " +"("x_pos+","+y_pos+")");
            y_pos++;
            if(y_pos > 12){
                x_pos++;
                y_pos = 0;
            }

            if(x_pos > 12) timer.stop();
        }

    }
}
