Question

Okay so I have two import pieces of code involved in this. This first tiny bit is what creates an object called OBJECT_arrow. It is located in the main function of my main class:

new OBJECT_arrow().CREATE(this,200,200);

It isn’t really all that important. Now this next bit is the OBJECT_arrow class. What it does is loads an external png image and draws it.

package
{
    import flash.net.URLRequest;
    import flash.display.*;
    import flash.system.*;
    import flash.events.*;
    import Math;
    public class OBJECT_arrow extends Sprite
    {
        public var X:Number = 0;    public var Y:Number = 0;
        public var DEPTH:int = 0 ;
        public var CONTAINER:Sprite = new Sprite();
        public var imageLoader:Loader = new Loader();
        public var image:URLRequest = new URLRequest ('ARROW.png');
        public function CREATE(CONTAINER:Sprite,X:Number,Y:Number):void
        {
            this.X = X;     imageLoader.x = this.X;
            this.Y = Y;     imageLoader.y = this.Y;
            this.CONTAINER = CONTAINER;
            CONTAINER.stage.addEventListener(Event.ENTER_FRAME,STEP);
            imageLoader.load(image);
            DRAW();
        }

        public function STEP(event:Event):void
        {
            DRAW();
        }

        public function DRAW():void 
        {
            addChild (imageLoader);
            (CONTAINER as MAIN).DRAW_LIST[(CONTAINER as MAIN).DRAW_LIST.length] = this;
            (CONTAINER as MAIN).DRAW_LIST[(CONTAINER as MAIN).DRAW_LIST.length] = DEPTH;
        }
    }
}

Now I know the mathematics behind rotation and know to rotate before I translate and everything but I simply don’t know how to apply the transformation to an external image in as3.

Answer 1

When you load an image with Loader it is stored as an object of type DisplayObject.

If you want it to be rotated, just set the rotation property.
