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

(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：

4

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。
