Controls for android

Im trying to make a platformer for android and im just using basic arrow keys on the screen for the controls. however i just found out how to make the camera follow the player and i dont know how to make the arrows stay on the same spot on the screen rather than where they were placed as a sprite.

Alright ive figured out how to use the layers, is there any way i can copy a layer and use it a different scene?

You could create an external layout and place all objects on a new layer. (I guess you are trying to create a user interface)
Then you can use the “create objects from external layout” action to add them to any scene. You can do the same with external events to link the corresponding logic into every scene where you instantiated the objects from the external layout.
