八月份cocos2d-x官网发布了v3.0版本,这次更新的内容特别多,包括2dx的架构以及使用
总得来说,给开发者带来了很大的便利:
运行环境需求:
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) 编译环境需求: 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)
重要更新内容: Replace Objective-C patters with C++ (C++11) patterns and best practices Improve Labels Improve renderer 其中C++ 11 新特性:
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 anstd::function<voID()>
CallFuncNcan be created with anstd::function<voID(Node*)>
CallFuncND
andCallFuncO
were removed since it can be created with simulated withCallFuncN
andCallFunc
. See ActionsTest.cpp for more examples MenuItemsupportsstd::function<voID(Node*)>
as callbacks 强大枚举类型更新: 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 当虚函数被overrIDe关健字修饰时,子类实现时有overrIDe标记
Removed Objective-C patterns 移除了所有Object-c模式,删除了CC前辍使用纯C++函数
对于类的使用改变: 2dx-3.0 两也不用使用using coco2d namespace 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// v2.12CCMoveBy *action = (CCMoveBy*) move->copy();3action->autorelease();45// v3.06// No need to do autorelease,no need to do casting.7auto action = move->clone();Singletons use getInstance() and destroyInstance()
All singletons usegetInstance()
anddestroyInstance()
(if applicable) to get and destroy the instance.
Examples:
Director->getInstance() | |
CCDirector->endDirector() | Director->destroyInstance() |
etc... |
v2.1 methods are still available,but they were tagged as deprecated.
getters
Getters Now use theget
prefix.
node->boundingBox()
const
in their declaration. Example: 2virtual float getScale();345float getScale() const;
POD types
Methods that were receiving POD types as arguments (eg:TexParams
,Point
,250)">Size,etc.) are being passed asconst
reference.
voID setTexParameters(ccTexParams* texParams);voID setTexParameters(const ccTexParams& texParams);
Misc API Changes 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.

创建新项目: v3.0不再需要创建Xcode模版,使用create-multi-platform-projects.py来创建一个跨平台的项目,使用方法 1,cd 到2dx根目录,MAC平台使用./create-multi-platform-projects.py 然后提示: -bash: ./create-multi-platform-projects.py: /usr/bin/evn: bad interpreter: No such file or directory 没关系,我们打开.py文件,发现其实引用的是tools/project_creator/create_project.py 这文件 2,我们再cd 到project_creator文件中,使用 ./create_project.py -p <PROJECT_name> -k <PACKAGE_name> -l <cpp|lua|JavaScript> 3,这样我们就可以在2dx的projects文件夹中找到创建好的项目 关于项目的选择: 图示: 红包点选就可以选择对应运行平台 总结
