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：

?

1 2 3 4 5

<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：

?

1 2 3 4 5 6

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();

?

1 2 3 4

<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）

?

1 2 3 4 5 6 7 8 9 10 11 12

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。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

<code>| v2.1 struct names | v3.0 struct names | | ccColor3B         | Color3B | | ccColor4B         | Color4B | | ccColor4F         | Color4F | | ccVertex2F        | Vertex2F | | ccVertex3F        | Vertex3F | | ccTex2F           | Tex2F | | ccPointSprite     | PointSprite | | ccQuad2           | Quad2 | | ccQuad3           | Quad3 | | ccV2F_C4B_T2F     | V2F_C4B_T2F | | ccV2F_C4F_T2F     | V2F_C4F_T2F | | ccV3F_C4B_T2F     | V3F_C4B_T2F | | ccV2F_C4B_T2F_Triangle | V2F_C4B_T2F_Triangle | | ccV2F_C4B_T2F_Quad | V2F_C4B_T2F_Quad | | ccV3F_C4B_T2F_Quad | V3F_C4B_T2F_Quad | | ccV2F_C4F_T2F_Quad | V2F_C4F_T2F_Quad | | ccBlendFunc       | BlendFunc | | ccT2F_Quad        | T2F_Quad | | ccAnimationFrameData | AnimationFrameData | </code>

一些全局的定义：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

// in v2.1 ccColor3B color3B = ccc3(0, 0, 0); ccc3BEqual(color3B, ccc3(1, 1, 1)); ccColor4B color4B = ccc4(0, 0, 0, 0); ccColor4F color4F = ccc4f(0, 0, 0, 0); color4F = ccc4FFromccc3B(color3B); color4F = ccc4FFromccc4B(color4B); ccc4FEqual(color4F, ccc4F(1, 1, 1, 1)); color4B = ccc4BFromccc4F(color4F);   color3B = ccWHITE;   // in v3.0 Color3B color3B = Color3B(0, 0, 0); color3B.equals(Color3B(1, 1, 1)); Color4B color4B = Color4B(0, 0, 0, 0); Color4F color4F = Color4F(0, 0, 0, 0); color4F = Color4F(color3B); color4F = Color4F(color4B); color4F.equals(Color4F(1, 1, 1, 1)); color4B = Color4B(color4F);   color3B = Color3B::WHITE;

继续...
