Javascript Flash round 2

FIguring out the Javascript/Flash integration kit has lead to a much simpler solution. Looks like Macromedia has slipped in another nugget of usefulness in the Flash 8 release which, I might add, has penetrated the market remarkably fast. It’s called External Interface. I gotta thank Bobby for finding this one.

So forget the last post if you’re a progressive designer like myself, marching to the Flash 8 bugle. Using the same example as before replace your Actionscript with the following.

import flash.external.ExternalInterface;

ExternalInterface.addCallback("moveBall", this, moveBall);

function moveBall (p_x:Number, p_y:Number):Void {
    ball_mc._x = p_x;
    ball_mc._y = p_y;
}

And then replace your javascript with the following.

function move_ball () {
    x = document.moveball.x.value;
    y = document.moveball.y.value;

    if (navigator.appName.indexOf("Microsoft") != -1) {
      window['ball'].moveBall(x, y);
    } else {
      document['ball'].moveBall(x, y);
    }
}

Thats it! Just make sure you name your flash file “ball” and you’ve set allowScriptAccess to all or sameDomain. Get rid of all the extraneous files from before too, you don’t need them! View example.
