Libgdx - Check if a key is being held down?

问题:

I'm using the java libgdx game library and im curious if I can tell if a key is being HELD, not pressed and let go.

I need to know this because I'm going to play a shorter mp3 file if it is just pressed and a longer one if it is held.

Yes, you can easily check they either via Gdx.input.isKeyPressed(Input.Keys.XXX) or by implementing an InputProcessor.

public class MyInputProcessor implements InputProcessor {      public boolean keyPressed;      @Override     public boolean keyDown(int keycode) {         if (keycode == Input.Keys.XXX) {             keyPressed = true;         }          return false;     }      @Override     public boolean keyUp(int keycode) {         if (keycode == Input.Keys.XXX) {             keyPressed = false;         }          return false;     } } 

And using it like this:

MyInputProcessor processor = new MyInputProcessor(); Gdx.input.setInputProcessor(processor);  ...  if (processor.keyPressed) {     // do some stuff } 

You can read more about that here.
