A regular hierarchy chart may look like this:
A scene (implemented with the CCScene object) is more or less an independent piece of the app workflow. Some people may call them ¡°screens¡± or ¡°stages¡±. Your app can have many scenes, but only one of them is active at a given time.
+A scene (implemented with the CCScene object) is more or less an independent piece of the app workflow. Some people may call them "screens" or "stages". Your app can have many scenes, but only one of them is active at a given time.
A cocos2d CCScene is composed of one or more layers (implemented with the CCLayer object), all of them piled up. Layers give the scene an appearance and behavior; the normal use case is to just make instances of Scene with the layers that you want.
There is also a family of CCScene classes called transitions (implemented with the CCTransitionScene object) which allow you to make transitions between two scenes (fade out/in, slide from a side, etc).
Since scenes are subclasses of CCNode, they can be transformed manually or by using actions. See Actions for more detail about actions.
The CCDirector is the component which takes care of going back and forth between scenes.
-The CCDirector is a shared (singleton) object. It knows which scene is currently active, and it handles a stack of scenes to allow things like ¡°scene calls¡± (pausing a Scene and putting it on hold while another enters, and then returning to the original). The CCDirector is the one who will actually change the CCScene, after a CCLayer has asked for push, replacement or end of the current scene.

A CCLayer has a size of the whole drawable area, and knows how to draw itself. It can be semi transparent (having holes and/or partial transparency in some/all places), allowing to see other layers behind it. Layers are the ones defining appearance and behavior, so most of your programming time will be spent coding CCLayer subclasses that do what you need.
The source code of these tutorials is here: https://github.com/lihex/Cocos2dxSimpleGame. You can follow the articles to finish the game by yourself step by step, or download the finally source, simply build and run it.

+Firstly, it's necessary to track the enemies and the bullets.
In the game, we add a tag for these two kinds of sprites to identify them. tag = 1 stands for a enemy, and tag = 2 means a bullet. Because there is already a member named m_nTag of CCNode, and the methods setTag() and getTag() also exist, CCSprite has inherited them, which we could utilize.
Add the two member variabls below to HelloWorld in HelloWorldScene.h, these two member variables are used to store the existing enemies and bullets.

How to play music and sund effect
In this chapter, we would add background music to the game and play sound effect when the hero fires bullets.
-Because there¡¯s so few codes to add that we could say a little more about audio engine here. Cocos2d-x has wrapped SimpleAudioEngine to cross platforms. In our game, we are able to play music and sound effect using only one line of codes. It is so convenient. Of course, audio formats supported in different platform are different, about this issue, you could refer to Audio_formats_supported_by_CocosDenshion_on_different_platforms.

+Now let's get right to the issues.
First, copy the sound files background-music-aac.wav and pew-pew-lei.wav to the Resource directory. We use wav here because wav is supported in all platforms and these two files have been included in the Cocos2dSimpleGame project, you could download them from the bottom of this page.
Then include SimpleaudioEngine.h in HelloWorldScene.cpp.
