Button/Key

Button or key input. This is not the button component.

Versions before 4.0 all handled key input with the InputSystemController script on individual components. Which is optional now.

Input is handled with two different scripts.

1. Button Input Processor

Controls the behavior of the UI on the scene. Dictates if they should individually handle by the components themselves or by the button input processor.

2. Button Input System

Attached to UI elements that can/should be controlled. If individual controls are selected, this controls the button input as well, otherwise, it is called by the button input processor when required and this calls the proper methods for the UI element like list.
