Back Button Stack

openupm

Easily manage a stack of objects that respond to the ESC button / Android Back button in Unity, so that only the top object handles the event.

Check out the Popup Stack sample scene for some usage example.

Features

  • Only the last object in the stack will be called when the ESC/Back button is pressed.
  • Inherit ABackButtonHandler to have scripts that handle the ESC/Back button be inserted/removed from the singleton stack automatically in their OnEnable / OnDisable methods.
  • Supports pure C# classes as well, just implement the IBackButtonHandler interface and call AddToBackButtonStack and RemoveFromBackButtonStack to add / remove it from the singleton stack.
  • Custom inspector for debugging which objects are currently in the stack, just select the BackButtonStack object in the DontDestroyOnLoad scene while in Play Mode.
