How do I have differents layers syze in my game?

Hello,

I'am making a mobile game. I have different layers, one for the game itself and other for the HUD.

I want to keep the green part for the game itself and the rest for buttons and stuff. So i want to avoid that the object go on a buttons or stuff like this.

I use behavior like wrap. Is there a way?

Create a border with collision, like a sprite with solid behaviour. It really depends on what your game is about.
