inputManager.addMapping(InputMapping.StrafeLeft.name(),
new KeyTrigger(KeyInput.KEY_A), new
KeyTrigger(KeyInput.KEY_LEFT));
inputManager.addMapping(InputMapping.StrafeRight.name(),
new KeyTrigger(KeyInput.KEY_D), new
KeyTrigger(KeyInput.KEY_RIGHT));
inputManager.addMapping(InputMapping.MoveForward.name(),
new KeyTrigger(KeyInput.KEY_W), new
KeyTrigger(KeyInput.KEY_UP));
inputManager.addMapping(InputMapping.MoveBackward.name(),
new KeyTrigger(KeyInput.KEY_S), new
KeyTrigger(KeyInput.KEY_DOWN));
}
Note
It's okay to assign several keys to the same mapping. For example, this recipe as-
signs both the arrow keys and the classical WASD pattern to the movement keys.
5. Finally, in the same method, we tell InputManager to listen to the commands,
or it won't actually fire on any of the inputs:
for (InputMapping i : InputMapping.values()) {
inputManager.addListener(this, i.name());
}
6. Now, once AppState is attached, it runs the initialize method (in a
thread-safe way). Here, we get the reference to the application's InputMan-
ager object and run the addMappings method we just created, as follows:
public void initialize(AppStateManager stateManager,
Application app) {
super.initialize(stateManager, app);
this.inputManager = app.getInputManager();
