cocos2d-x v2 升级到 v3

概述常用类名改变 删除了CC前缀 CCAction CCAction -> Action CCPoint -> Point CCAnimation -> Animation CCSprite -> Sprite CCLabel -> Label CCMenu -> Menu CCObject -> Ref CCNode -> Node CCScene -> Scene CCLayer -> Layer 常用类名改变

删除了CC前缀
CCAction

CCAction -> Action
CCPoint -> Point
CCAnimation -> Animation
CCSprite -> Sprite
cclabel -> Label
Ccmenu -> Menu
CCObject -> Ref
CCNode -> Node
CCScene -> Scene
cclayer -> Layer
CCSpriteBatchNoe -> SpriteBatchNode
CCTMXTiledMap -> TMXTiledMap
CCDictionary -> ValueMap
CCArray -> ValueVector
CCString -> Value

CCString 改变

之前:

CCString* str = CCString::createWithFormat("%s.png","picture");

之后:

std::string str = StringUtils::format("%s.png","picture");

CCDictionary 改变

之前:

CCDictionary* dict = CCDictionary::createWithContentsOffile("name.pList");CCArray* arr = (CCArray*) dict->objectForKey("Levels");

之后:

std::string path = fileUtils::getInstance()->fullPathForfilename("name.pList");ValueMap dict = fileUtils::getInstance()->getValueMapFromfile(path);ValueVector arrLevels = dict.at("Levels").asValueVector();

CCArray 改变

改为标准的vector容器

CCArray* arr; -> ValueVector arr;
arr->addobject(sprite); -> arr.pushBack(sprite);
arr->removeObject(sprite); -> arr.eraSEObject(sprite);
arr->removeObjectAtIndex(i); -> arr.erase(i);
arr->objectAtIndex(i); -> arr.at(i);
arr->count(); -> arr.size();

触摸函数改变

cctouchBegan -> ontouchBegan
cctouchmoved -> ontouchmoved
cctouchended -> ontouchended

MenuItem 菜单 变化

ccMacros.h中宏定义

// new callbacks based on C++11#define CC_CALLBACK_0(__selector__,__target__,...) std::bind(&__selector__,##__VA_ARGS__)#define CC_CALLBACK_1(__selector__,std::placeholders::_1,##__VA_ARGS__)#define CC_CALLBACK_2(__selector__,std::placeholders::_2,##__VA_ARGS__)#define CC_CALLBACK_3(__selector__,std::placeholders::_3,##__VA_ARGS__)

v2调用方法

cmenuItemImage *item1 = CcmenuItemImage::create(s_pPathB1,s_pPathB2,this,menu_selector(ActionsDemo::backCallback));

v3调用方法1

MenuItemImage *item1 = MenuItemImage::create(s_pPathB1,CC_CALLBACK_1(ActionsDemo::backCallback,this));

v3调用方法2

MenuItemImage *item1 = MenuItemImage::create(s_pPathB1,[=](Ref* sender){ //code here }););

UserDefault::sharedUserDefault -> UserDefault::getInstance
UserDefault::purgeSharedUserDefault -> UserDefault::destroyInstance
Application::sharedApplication -> Application::getInstance
kBlendFuncdisable -> BlendFunc::BLEND_FUNC_disABLE

CCTime 改变

cc_timeval -> timeval
CCTime::gettimeofdayCocos2d -> gettimeofday
CCTime::timesubCocos2d -> getTimeDiffenceMS
事例:

static inline float getTimeDifferenceMS(timeval& start,timeval& end){ return ((((end.tv_sec - start.tv_sec)*1000.0f + end.tv_usec) - start.tv_usec) / 1000.0f);}

OpenGL 变化

一般做游戏不太涉及得到

CCGLProgram -> GLProgram
kCCUniformPMatrix_s -> GLProgram::UNIFORM_name_P_MATRIX
kCCUniformMVMatrix_s -> GLProgram::UNIFORM_name_MV_MATRIX
kCCUniformMVPMatrix_s -> GLProgram::UNIFORM_name_MVP_MATRIX
kCCUniformTime_s -> GLProgram::UNIFORM_name_TIME
kCCUniformSinTime_s -> GLProgram::UNIFORM_name_SIN_TIME
kCCUniformCosTime_s -> GLProgram::UNIFORM_name_COS_TIME
