How can I specify ENTER_FRAME so that the object enters on every 4th frame?

Question

So the ENTER_FRAME property will add an object to the stage on every frame the game runs. If the game is 24 fps, 24 objects created per second. How can I limit that so it will generate an object every 4 frames?

Answer 1

you can have a counter that increments every frame

var f:int = 0;
addEventListener(Event.ENTER_FRAME,onEnterFrame);
function onEnterFrame(e:Event):void{
    if (f%4 == 0){
        // do something
    }
    f++;
}

you can set f=0; inside the if statement if you like
