Passing parameters between layers of a scene

Hi,
I’m trying to get two layers of a scene to communicate and have one layer pass a “position” variable to another layer.

The whole concept of layers is very new to me, so I’m also wondering when and how you should use a layer, and whether I should at all be trying to pass variables between them.

Thanks in advance for your help

Well, show us your classes. I mean if you are creating both layers in the same class then just pass it.
