public void touchDown(float x,
                      float y)

touchReleased

public void touchReleased(float x,
                          float y)

touchMove

public void touchMove(float x,
                      float y)

animationEnter

public abstract void animationEnter(float factor)

animationExit

public abstract void animationExit(float factor)
