Cocos2dx 3.0 交流篇

创建项目: For(MAC)

Runtime Requirements

Android 2.3 or newer
iOS 5.0 or newer
OS X 10.7 or newer
Windows 7 or newer
Linux Ubuntu 12.04 (or newer)
cocos2d-x v3.0rc(or newer)

Software
Requirements

Xcode 4.6 (for iOS or Mac)
gcc 4.7 for Linux or Android. For Android ndk-r9 or newer is required.
Visual Studio 2012 (for Windows)
Python 2.7.5

Create
A New Project

$ cd cocos2d-x

$ ./setup.py

$ source ~/.bash_profile # may be ~/.bash_login or ~/.profile, depends on your environemnt

$ cocos new MyGame -p com.MyCompany.MyGame -l cpp -d ~/MyCompany

MyGame: name of your project
-p com.MyCompany.MyGame: package name for android
-l cpp: programming language used for the project, valid
value is cppand lua
-d ~/MyCompany: directory to hold your project

Folder structure of the generated project is as following:

(Note: The directory may be different when the project type is lua.)

Build
And Run New Project

$ cocos run -s ~/MyCompany/MyGame -p ios

-s: directory of the new project. This could be an absolute
path or a relative path.
-p: which platform to run on. Options are ios,android,win32,mac and linux.

(Note: You are a tmux user, you should add reattach-to-user-namespace before
the command cocos. For more information, please refer to this
link for more information.)

You can run cocos run --help for more detail information.

体验变化:

1、以CC开头的类从此去掉CC。如：

<code>|

 v2.

1



| v3.

0

|

 CCSprite   | Sprite   |

|

 CCNode     | Node     |

|

 CCDirector | Director |

|

 etc...                |</code>

举个样例，创建一个精灵的方式：

v2.0

CCSprite*

 sp = CCSprite::create();

v3.0

auto

 sp = Sprite::create();

2、clone() 替代 copy(), 这个我用的不多。所以也就不多交代了；

3、Director的单例换成getInstance() 和 destroyInstance();

<code>|

 v2.

1



| v3.

0

|

 CCDirector->sharedDirector()  | Director->getInstance()     |

|

 CCDirector->endDirector()     | Director->destroyInstance() |

|

 etc...                                                      |</code>

|

4、新的触摸机制，先贴一段代码给大家看看，可能是下一篇或者下下篇我会具体讲下新的触摸机制的。（嘻嘻。搞得我好像非常牛逼哄哄的样子）

auto

 sprite = Sprite::create(

"file.png");

...

auto

 listener = EventListenerTouchOneByOne::create();

listener->setSwallowTouch(true);

listener->onTouchBegan    

 = [](Touch* touch, Event* event) { do_some_thing();

return



true

; 

 };

listener->onTouchMoved    

 = [](Touch* touch, Event* event) { do_some_thing();  };

listener->onTouchEnded    

 = [](Touch* touch, Event* event) { do_some_thing();  };

listener->onTouchCancelled

 = [](Touch* touch, Event* event) { do_some_thing();  };

//

 The priority of the touch listener is based on the draw order of sprite

EventDispatcher::getInstance()->addEventListenerWithSceneGraphPriority(listener,

 sprite);

//

 Or the priority of the touch listener is a fixed value

EventDispatcher::getInstance()->addEventListenerWithFixedPriority(listener,

100

);

//

 100 is a fixed value

5、另一些杂七杂八的东西，本人理解的不透。也就不发出来献丑了。最后将CCType.h 里的一些变动贴出来，让我们愉快的结束这篇博文。

一些全局的定义：

//

ccColor3B

 color3B = ccc3(

0

0);

ccc3BEqual(color3B,

 ccc3(

1

1));

ccColor4B

 color4B = ccc4(

0

0);

ccColor4F

 color4F = ccc4f(

color4F

color4F

 = ccc4FFromccc4B(color4B);

ccc4FEqual(color4F,

 ccc4F(

1

1));

color4B

 = ccc4BFromccc4F(color4F);

color3B

 = ccWHITE;

//

 in v3.0

Color3B

 color3B = Color3B(

0

0);

color3B.equals(Color3B(1

1

1));

Color4B

 color4B = Color4B(

0

0);

Color4F

 color4F = Color4F(

0

0);

color4F

 = Color4F(color3B);

color4F

 = Color4F(color4B);

color4F.equals(Color4F(1

1

1));

color4B

 = Color4B(color4F);

color3B

 = Color3B::WHITE;
