cocos2d-x v2 升级到 v3

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__,__target__, ##__VA_ARGS__)
#define CC_CALLBACK_1(__selector__,__target__, ...) std::bind(&__selector__,__target__, std::placeholders::_1, ##__VA_ARGS__)
#define CC_CALLBACK_2(__selector__,__target__, ...) std::bind(&__selector__,__target__, std::placeholders::_1, std::placeholders::_2, ##__VA_ARGS__)
#define CC_CALLBACK_3(__selector__,__target__, ...) std::bind(&__selector__,__target__, std::placeholders::_1, std::placeholders::_2, 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, s_pPathB2, CC_CALLBACK_1(ActionsDemo::backCallback, this));

v3调用方法2

MenuItemImage *item1 = MenuItemImage::create(s_pPathB1, s_pPathB2, [=](Ref* sender){
    //code here
}););
