Class InputComponent

java.lang.Object
com.csse3200.game.components.Component
com.csse3200.game.input.InputComponent
All Implemented Interfaces:
com.badlogic.gdx.input.GestureDetector.GestureListener, com.badlogic.gdx.InputProcessor, com.badlogic.gdx.utils.Json.Serializable
Direct Known Subclasses:
InputDecorator, KeyboardPlayerInputComponent, KeyboardTerminalInputComponent, KeyboardTractorInputComponent, TouchPlayerInputComponent, TouchTerminalInputComponent, TouchTractorInputComponent
public abstract class InputComponent extends Component implements com.badlogic.gdx.InputProcessor, com.badlogic.gdx.input.GestureDetector.GestureListener
An InputComponent that supports keyboard and touch input and touch gestures. By default an InputComponent does not handle any input events.

Subclasses of InputComponent should override relevant methods to handle input. Ensure the priority is set in the subclass' constructor.
