Have you tried looking at your running project using a debugger? Tools like De MonsterDebugger really help work out where the issues lie.

public function addBtns():void
{
	max = tempArray.length;
	var parentLayer:ViewportLayer;
	var vpl:ViewportLayer;
	// create an empty parent viewport layer and add it to the container
	parentLayer = new ViewportLayer(viewport,null);
	viewport.containerSprite.addLayer(parentLayer);
	// adding individual 2d oobjects with different x and y etc
	for (var i:int = 0; i < max; i++)
	{
		box = new menuHolder();
		// create text box (movieclip);
		// create do2d that encapsulates the movieclip
		menu = new DisplayObject2D(box as DisplayObject,parentLayer,0,null,5 * 1.25,0);
		// create layer and add to scene
		menu.useOwnContainer = true;
		//vpl = parentLayer.getChildLayer(menu,true);

		menu.x = tempArray[i].x;
		menu.y = tempArray[i].y;
		menu.z = tempArray[i].z;
		// drop down stuff
		var bodyDrop:DropDown = new DropDown(this[listArray + i],tempArray[i].title,true,this[listArray + i].length * 30);
		bodyDrop.addEventListener(DropDown.ITEM_SELECTED, newSelect);

		box.addChild(bodyDrop);
		box.name = "box" + i;
		menu.name = "menu" + i;
		menuArray.push(menu);
		scene.addChild(menu);
		//menu.alpha = 1;

		trace(menuArray[i]);
	}
	trace("starting menu",menu.scene);
}

// button to remove
public function removeHorseBtns():void
{
	for (var i:int = 0; i < max; i++)
	{
		menu = menuArray[i];
		// remove from scene
		if (menu.scene)
		{
			menu.scene.removeChild(menu);
			// dispose
			menu = null;
		}

	}
	//this will be added to
	menuArray=[];
}

here’s how the removing of objects is done in Tweetpond:

// remove from array
shape = shapeArray.pop();

// remove from scene
if (shape.scene) shape.scene.removeChild(shape);

// dispose
shape = null;

Hope this helps.

Thanks again, this class is very handy.

var parentLayer:ViewportLayer;
var vpl:ViewportLayer;

parentLayer = new ViewportLayer(viewport, null);
viewport.containerSprite.addLayer(parentLayer);
// create text box (movieclip)
var box = new MenuCrossBtn();
var menu = new DisplayObject2D(box as DisplayObject, parentLayer, 0, null, 5*1.25, 0);
// create layer and add to scene
menu.useOwnContainer = true;
vpl = parentLayer.getChildLayer(menu, true);
menu.z=200;
menu.addEventListener(InteractiveScene3DEvent.OBJECT_CLICK, click1);
menu.name=”myBtn”;
scene.addChild(menu);

good question, I’ve tried mouse events in the past but they didn’t seem to work properly. If I remember correctly the click events were received fine, however the event target wasn’t always correct, so in the current version of Tweetpond clicking on objects is not enabled. I believe this is unrelated to the DisplayObject2D implementation.

I’ve posted some sample code below on setting up the events, perhaps someone else can have a look and work out why this doesn’t always work correctly when there are lots of objects in the scene?

Cheers, Jussi

public class MyView extends BasicView {
  // constant for our interactive setting
  public static const INTERACTIVE = true;

  public function MyView() {
    // interactive viewport allows clicking on objects
    super(stage.stageWidth, stage.stageHeight, true, INTERACTIVE, CameraType.TARGET);

    var obj:DisplayObject3D = createShape();

    // name displayobject
    obj.name = "my_sphere_001";

    // add event listeners
    obj.addEventListener(InteractiveScene3DEvent.OBJECT_CLICK, objClicked);

    ...
  }

  private function createShape():DisplayObject3D {
    var material:MaterialObject3D = new FlatShadeMaterial(LIGHT, COLOUR, AMBIENT_COLOUR);
    var materialsList:MaterialsList = new MaterialsList();

    material.interactive = INTERACTIVE;
    materialsList.addMaterial(material, "all");

    return new Sphere(material, SIZE);
  }

  private function objClicked(myEvent:InteractiveScene3DEvent):void {
    trace ("Clicked on " + myEvent.target.name);
  }
}

Thanks
