init object
var plane2:Mesh = new Mesh(new PlaneGeometry(300,300,1,1,false),redMaterial);
plane2.extra = "plane2";
plane2.mouseEnabled = true;
plane2.addEventListener(MouseEvent3D.MOUSE_DOWN,doubleHandler);
scene.addChild(plane2);
var plane3:Mesh = new Mesh(new PlaneGeometry(200,200,1,1,false),greenMaterial);
plane3.extra = "plane3";
plane3.mouseEnabled = true;
plane3.addEventListener(MouseEvent3D.MOUSE_DOWN,doubleHandler);
plane2.addChild(plane3);
var plane4:Mesh = new Mesh(new PlaneGeometry(100,100,1,1,false),yellowMaterial);
plane4.extra = "plane4";
plane4.mouseEnabled = true;
plane4.addEventListener(MouseEvent3D.MOUSE_DOWN,doubleHandler);
plane3.addChild(plane4);
doubleHandler code:
public function doubleHandler(event:MouseEvent3D):void{
trace(Mesh(event.target).extra);
trace(Mesh(event.currentTarget).extra);
trace("--------------------------------");
event.stopPropagation();
}
output:
plane4
plane4
--------------------------------
plane3
plane3
--------------------------------
plane2
plane2
--------------------------------

This sounds like a bug. I’ll file it myself and fix it ASAP, probably later today.
Cheers!

Dear Richard,I think the child plane should on top of the parent plane both same z value.in another word, we can see both child plane and parent plane if child is smaller than parent.
but now, the child plane is hiden by parent plane both same z value.
Am I right? Thank you very much.

I’m not sure what you mean. The hierarchy of objects should (typically) not influence what objects appear in front of others. It’s entirely up to their relative Z position in screen space, and the GPU does the sorting per pixel.
The exception is when you use alpha transparency and the objects thus have to be sorted on the CPU. In those cases, objects in the exact same screen-space Z position can be sorted differently depending on the order in which they were added to their parent (as a result of the sorting algorithm.)

There is a picture
ok,I see…. I have to type some code to change every plane’s z value,it’s that right?

Yes, in a 3D engine the idea is that you position things in 3D space. Objects are not sorted in relation to the order that they were added to the scene, and the hierarchy generally has no influence on how they are depth sorted on the screen.
