Using this in GamePlayLoop() Constructor:
GamePlayLoop(this)
Open up your .createStartGameLoop() method structure, using the + expand icon on
the left side of NetBeans, as shown in Figure 12-9 . Add the Java this keyword in the
parameter area, so that you are again passing the InvinciBagel object reference, this

private void createStartGameLoop() {
gamePlayLoop = new GamePlayLoop( this );
gamePlayLoop.start();
}
