This seems like it’s a bug in Away3D 4.x, but I’m posting here to get some sort of confirmation before I submit it to github. I am trying to add mouseOver and mouseOut events to a sprite3d object using a PickingColliderType.AS3_BEST_HIT, or really any collider type besides the default bounding box one, and I get null object exception errors when the event triggers.
_spriteMaterial = new ColorMaterial(0xe01f1f);
_spriteSquare = new Sprite3D(_spriteMaterial, 20, 5);
_spriteSquare.pickingCollider = PickingColliderType.AS3_BEST_HIT;
_spriteSquare.showBounds = true;
_spriteSquare.mouseEnabled = true;
_spriteSquare.addEventListener(MouseEvent3D.MOUSE_OVER, spriteSquare_mouseOver);
_spriteSquare.addEventListener(MouseEvent3D.MOUSE_OUT, spriteSquare_mouseOut);
private function spriteSquare_mouseOver(e:MouseEvent3D):void
{
trace("spriteSquare_mouseOver");
}
private function spriteSquare_mouseOut(e:MouseEvent3D):void
{
trace("spriteSquare_mouseOut");
}
When I trigger the mouseOver event I get a null object exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Am I doing something wrong with my implementation, or is this really a bug?
