Cocos2d-x3.0新機能-沈海Cocos 2 d-x 3.0チュートリアル1

3.0時代は間もなく到来して、ついにObjective-cの影を抜け出して、C++に復帰して、そして強大なC++11の新しい特性を支持して、小さいニュース:2014年10との開発者大会は正式版を出すことができて、しかし私は開発チームがやはり2.2を基礎に審査することを提案して、3.0が完備してから更に新しいバージョンを待って、しかし先に研究することができますか.
Cocos2d-x3.0環境要件の実行:

Android 2.3 or newer

iOS 5.0 or newer
OS X 10.7 or newer
Windows (which version?)
Linux Ubuntu 12.04 (or newer)
コンパイル環境の要件:
Xcode 4.6 (for iOS or Mac)
gcc 4.7 for Linux or Android. For Android ndk-r8e or newer is required.

Visual Studio 2012(for Windows)(XPシステムで開発中の子供靴、交換済み)

重要な更新内容:

Replace Objective-C patters with C++ (C++11) patterns and best practices

Improve Labels

Improve renderer

ここでC++11の新しい特性:
A subset of C++11 features are being used in cocos2d-x:

std::function , including lambda objects for callbacks

strongly typed enums, for most of the cocos2d-x enums and constants

std::thread  for threading

override  context keyword, for overriden methods

st  std::function CallFunc  can be created with an  std::function<void()> CallFuncN  can be created with an  std::function<void(Node*)>

CallFuncND  and  CallFuncO  were removed since it can be created with simulated with  CallFuncN  and  CallFunc . See ActionsTest.cpp for more examples

MenuItem  supports  std::function<void(Node*)>  as callbacks
強力な列挙タイプの更新:
Examples:
v2.1
v3.0 kCCTexture2DPixelFormat_RGBA8888 Texture2D::PixelFormat::RGBA8888 kCCDirectorProjectionCustom Director::Projection::CUSTOM ccGREEN Color3B::GREEN CCPointZero Point::ZERO CCSizeZero Size::ZERO
The old values can still be used, but are not deprecated.
override
虚関数がoverride関健字で修飾されると,サブクラス実装時にoverrideタグがある.
Removed Objective-C patternsはすべてのObject-cモードを除去し、CCを削除する前に中退して純粋なC++関数を使用する
クラスの使用の変更:
2 dx-3.0両方ともusing coco 2 d namespaceを使用しない
     clone() instead of copy() clone()  returns an autoreleased version of the copy. copy()  is no longer supported. If you use it, it will compile, but the code will crash.
Example:

1// v2.1
2CCMoveBy *action = (CCMoveBy*) move->copy();
3action->autorelease();
4
5// v3.0
6// No need to do autorelease, no need to do casting.
7auto action = move->clone();

     
     Singletons use getInstance() and destroyInstance()
All singletons use  getInstance()  and  destroyInstance()  (if applicable) to get and destroy the instance.
Examples:
v2.1
v3.0 CCDirector->sharedDirector() Director->getInstance() CCDirector->endDirector() Director->destroyInstance()
etc...
v2.1 methods are still available, but they were tagged as deprecated.
     getters
Getters now use the  get  prefix.
Examples:
v2.1
v3.0 node->boundingBox() node->getBoundingBox() sprite->nodeToParentTransform() sprite->getNodeToParentTransform()
etc...
And getters were also tagged as  const  in their declaration. Example:

1// v2.1
2virtual float getScale();
3
4// v3.0
5virtual float getScale() const;

v2.1 methods are still available, but they were tagged as deprecated.
     POD types
Methods that were receiving POD types as arguments (eg:  TexParams ,  Point ,  Size , etc.) are being passed as  const reference.
Example:

1// v2.1
2void setTexParameters(ccTexParams* texParams);
3
4// v3.0
5void setTexParameters(const ccTexParams& texParams);

   Misc API Changes   ccTypes.h
Remove cc prefix for structure names in ccTypes.h, move global functions into static member functions, and move global constants into const static member variables.
