Playing with Away3D

by Harry

I have just spent a couple of hours last night getting to grips with Away3D. I just created a little demo that creates a few spheres and then adds an ENTER_FRAME event listener and responds to mouse movement.

You can download the whole thing here: http://harry-northover-code-store.googlecode.com/files/Away3DBasics.zip

Here is a screene:

And here’s the code:

				sphere.invertFaces();
				sphere.x = Math.random() * 1000;
				sphere.y = Math.random() * 1000;
				sphere.z = Math.random() * 600;
				sphere.rotationX = Math.random() * 360;
				sphere.rotationY = Math.random() * 360;
				view.scene.addChild(sphere);
			}
 
			// Add Event listeners.
			this.addEventListener(Event.ENTER_FRAME, onRun);
 
			// Render the scene...
			cam.hover();
			view.render();
 
		}
 
		// This is the code for the ENTER_FRAME event.
		private function onRun(evt:Event):void {
			cam.rotationX = Math.random() * 360;
			cam.rotationY = Math.random() * 360;
			cam.rotationZ = Math.random() * 360;
			cam.pan(Math.random() * 360);
			Tweener.addTween(cam, { zoom: (stage.mouseY / stage.stageHeight) * 4 + 0.5, time:0.1, transition:"easeInOutExpo" } );
			cam.hover();
			view.render();
		}
	}
}

There you go! I will be doing a lot more stuff with Away3D so keep an eye out!
