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

  • 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

new game

Folder structure of the generated project is as following:

folder structure

(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。
