In this chapter, we have reviewed different animation techniques and learned when to use a certain type of animation taking into account its pros and cons.

While learning about animations, we have added a nice old-school bird fall animation, so it no longer just disappears from the screen.

In the second part of the chapter, we met particle systems, which are really cool and can add some very nice effects to your game. We created one from the ground up, used the predefined particle system provided by Cocos2D, and took a short look at some tools that allow you to create particle systems in almost no time.

Just as with animations, we had a chance to add a particle system to our game and added a feather explosion when the arrow hits the bird. This way all of our objects have corresponding reactions on different game events and our Cocohunt game scene is currently very close to a simple but complete level.

In the chapters ahead, we will add sound and a user interface and it will look even...
