PickedMesh

[Adem]

I put some mesh into my imported 3D scene, i tried to register a pick function on the mesh but it's not working.

newScene.onPointerDown = function (evt, pr) { 
var width = newScene.getEngine().getRenderWidth(); 
var height = newScene.getEngine().getRenderHeight(); 
var pickInfo = newScene.pick(width / 2, height / 2);
 if (pickInfo.hit) {
pickInfo.pickedMesh.dispose(); 
} 
};

I have two ideas what might be wrong:

1)

You code always picks the center of the scene, is that intended?
I mean, you do not reference the pointer position.

2)

Also is your mesh pickable?
mesh.isPickable = true;
If it's not it gets ignored.

 

Here is a playground that uses your pick code, that picks the sphere and disposes it.

But there is something weird going on here, because disposing the sphere in the click event also removes the ground from the scene.
This seems to me like a bug. Maybe @Deltakosh can have a look, at this.
If you replace the dispose with anything else, for example "pickInfo.pickedMesh.visibility -= 0.1" only the sphere is affected. So the picking works, but dispose called from a pointer event does something strange.

One more question about meshes picking.

I can get one mesh (top one) under cursor using the method: var pickResult = scene.pick............

But how can I get a list of meshes under a cursor position? I mean all meshes under a cursor position.

I found the solution: scene.multiPick
