Layers

Unity Engine

Hi,

I’m having some problems with layers in my game objects. I have a game object called SkyCylinder and it have a child game object called Mesh. I’m trying to change the layer on the Mesh object from script but only the SkyCylinder object get altered.

How can I access a child game object? Currently I’m doing like this:

MeshRenderer renderer = m_GameObject.GetComponentInChildren(typeof(MeshRenderer)) as MeshRenderer;
if (renderer != null)
{
   jb_Debug.Info("renderer.gameObject.name=" + renderer.gameObject.name);
   renderer.gameObject.layer = m_Layer;
}

The output is saying that the game object name is “Mesh” but when I change the layer only the parent game object is changed.

Thanks!

That’s because, in effect, that is exactly what you’re doing. m_GameObject and renderer.gameObject are one and the same!

MeshRenderer renderer = m_GameObject.renderer;
GameObject gameObject = renderer.gameObject;
if (gameObject == m_GameObject)
{
   Debug.Log("Aha!");
}

You can’t change the layer property on the renderer itself, since the renderer doesn’t have that property (the GameObject does).

What were you trying to accomplish?

When I load an fbx into a game object I get a hierarchy like this:

SkyCylinder (GameObject and root object)

Mesh (GameObject I think)

Renderer (Component)
Other (Components)

I want to change the layer on the “Mesh” object. And I think I got it to work but I’m not sure until I test on another computer. Sometimes the meta data stored locally on my computer makes things work.
