Time for action – handling touches

Time to bring the player to our party:

1. Time to implement our onTouchBegan method. We'll begin by handling the two game states, intro and game over:

   bool GameLayer::onTouchBegan (Touch * touch, Event * event){
   
     //if game not running, we are seeing either intro or  //gameover
     if (!_running) {
       //if intro, hide intro message
       if (_introMessage->isVisible()) {
         _introMessage->setVisible(false);
   
         //if game over, hide game over message 
       } else if (_gameOverMessage->isVisible()) {
         SimpleAudioEngine::getInstance()->stopAllEffects();
         _gameOverMessage->setVisible(false);
         
       }
       
       this->resetGame();
       return true;
     }

2. Here we check to see if the game is not running. If not, we check to see if any of our messages are visible. If _introMessage is visible, we hide it. If _gameOverMessage is visible, we stop all current sound effects and hide the message as well. Then we call a method called resetGame...
