• 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)

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
• @H_502_72@std::threadfor threading
• @H_502_72@overridecontext keyword,for overriden methods

st std::function

• @H_502_72@CallFunccan be created with an@H_502_72@std::function<void()>
• CallFuncNcan be created with an@H_502_72@std::function<void(Node*)>
• @H_502_72@CallFuncNDand@H_502_72@CallFuncOwere removed since it can be created with simulated with@H_502_72@CallFuncNand@H_502_72@CallFunc. See ActionsTest.cpp for more examples
• MenuItemsupports@H_502_72@std::function<void(Node*)>as callbacks

The old values can still be used,but are not deprecated.

Removed Objective-C patterns

clone() instead of copy()

@H_502_72@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@H_502_72@getInstance()and@H_502_72@destroyInstance()(if applicable) to get and destroy the instance.

Examples:

v2.1 methods are still available,but they were tagged as deprecated.

Getters now use the@H_502_72@getprefix.

node->boundingBox() node->getBoundingBox() sprite->nodeToParentTransform() sprite->getNodeToParentTransform() And getters were also tagged as@H_502_72@constin their declaration. Example:

2virtual float getScale();
3
45float getScale() const;

POD types

Methods that were receiving POD types as arguments (eg:@H_502_72@TexParams,@H_502_72@Point,250)">Size,etc.) are being passed as@H_502_72@constreference.

void setTexParameters(ccTexParams* texParams); void setTexParameters(const ccTexParams& texParams);

Misc API Changes

@H_502_72@ ccTypes.h

Removeccprefix for structure names in ccTypes.h,move global functions into static member functions,and move global constants into const static member variables.

Global functions changed example
