Implementing pause and resuming the game

Now, we implement the pause and resume buttons in HelloWorldScene:

We will add the gamePaused() and gameResumed() functions in the HelloWorldScene class. For this, create two functions in the HelloWorldScene.h:

    void gamePaused();
    void gameResumed();

Next, we define these functions in the HelloWorldScene.cpp file:

void HelloWorld::gamePaused()
{
    this->unscheduleUpdate();
    this->unschedule(schedule_selector(HelloWorld::spawnEnemy));

    if(gameplayLayer->getEnemiesArray()->count() >0)
    {
        for(int i=0; i< gameplayLayer->getEnemiesArray()->count(); i++)
        {
            Enemy* en = (Enemy*) gameplayLayer->getEnemiesArray()->objectAtIndex(i);
            en->pauseSchedulerAndActions();
        }
    }
}

Once the game is paused, we unschedule the update and ...
