In the
updateLevelEnd()
method, we check for a touch event; if there has been one, we create a
new
World
and
WorldRenderer
instance. We also tell the
World
to use the score achieved so far
and set the game screen to the
GAME_READY
state, which will again wait for a touch event.
private void
updateGameOver() {
List<TouchEvent> touchEvents = game.getInput().getTouchEvents();
int
len = touchEvents.size();
for
(
int
i = 0; i < len; i++) {
TouchEvent event = touchEvents.get(i);
if
(event.type != TouchEvent.
TOUCH
_

)
continue
;
game.setScreen(
new
MainMenuScreen(game));
}
}
In the
updateGameOver()
method, we again just check for a touch event, in which case we simply
transition back to the main menu, as indicated in Figure
9-2
.
Rendering the GameScreen
After all those updates, the game screen will be asked to render itself via a call to
GameScreen.
present()
. Let's have a look at that method in Listing 9-22.
