but I’m sure it gets boring after a while. Let’s add some huge floating rocks that will crash the ship upon collision. Bellow the camera code in create(), add the following: 1 this.generateAsteriods(); hitAsteroid, null, this); Define the hitAsteroid() method where we play an explosion sound, destroy the ship and go to game over: 1 hitAsteroid: function(player, asteroid) { 2 //play explosion sound add(800, this.gameOver, this); 10 }, Particles and Game Over When you hit a rock we can make the ship explode using particles. Particles are a game development technique that allows you to work with

Networking Process Memory Flying for years across the galaxy and back, The crew learned to modify their ship and adjust. They changed the thrusters, the force shields, the hyper- stack, To explore the most exotic beginning Of a whole new era for data sharing and messaging. Mail was still slow to go through the ship’s processors, But the electrician bee had a great idea. And so the swarm replaced legacy receivers things in order. The busy engine room was the ideal place To monitor all things happening on the ship, And the bees optimized, process after process, All the things that they could, to improve every trip
