《cocos2dx手机游戏开发》 源码基于cocos2d-x v2.2 下载

1.效果图(动态gif和代码在底部):

《cocos2d-x手机游戏开发:跨iOS、Android和沃Phone平台》讲了一个"魔塔"游戏，它是我看的第一本关于cocos2d-x的书，“魔塔”我小时候有玩过，没有想到若干年后能看到实现方式。但是比较遗憾的是这本书使用的cocos2d-x类库比较老，是cocos2d-0.99.5-x-0.8.5。我花了一点时间把整个代码升级到cocos2d-x v2.2。想要下载的童鞋直接拉到最底部进行下载。下面是部分新老API的变化。这种大量抛弃老API的方式还是第一次见到，不过我想这是移动开发的必然吧，新老API都存在，会影响类库文件大小，效率等。

2.部分cocos2d-x代码升级示例

2.1创建一个指针基本都用create，或者函数名带有create

//old 
GameLayer *gamelayer = GameLayer::node();
//new
GameLayer *gamelayer = GameLayer::create();

//old
LAYER_NODE_FUNC(GameLayer);
//new
CREATE_FUNC(GameLayer);

//old
CCLayerColor* fadeLayer = CCLayerColor::layerWithColor(ccc4(0, 0, 0, 0));
//new
CCLayerColor* fadeLayer = CCLayerColor::create(ccc4(0, 0, 0, 0));

//old
CCAction* action = CCSequence::actions(
		CCFadeIn::actionWithDuration(0.5f),
		CCCallFunc::actionWithTarget(this, callfunc_selector(GameScene::resetGameLayer)),
		NULL);
//new
CCAction* action = CCSequence::create(
		CCFadeIn::create(0.5f),
		CCCallFunc::create(this, callfunc_selector(GameScene::resetGameLayer)),
		NULL);		
		
//old
heroSprite = CCSprite::spriteWithSpriteFrame(defaultFrame)
//new
heroSprite = CCSprite::createWithSpriteFrame(defaultFrame);

//old
CCAnimation* animation = new CCAnimation();
animation->initWithFrames(animFrames, 0.1f);
//new
CCAnimation* animation = CCAnimation::createWithSpriteFrames(animFrames, 0.1f);

//old
return cocos2d::CCAnimate::actionWithAnimation(anim);
//new
return cocos2d::CCAnimate::create(anim);

//old
npcSprite = CCSprite::spriteWithFile(imagePath->m_sString.c_str(), rect);
//new
npcSprite = CCSprite::create(imagePath->m_sString.c_str(), rect);

//old
frame0 = CCSpriteFrame::frameWithTexture(heroTexture, cocos2d::CCRectMake(32*0, 32*direction, 32, 32));
//new
frame0 = CCSpriteFrame::createWithTexture(heroTexture, cocos2d::CCRectMake(32*0, 32*direction, 32, 32));

//old
CCMenuItemImage::itemFromNormalImage
CCMenu* pMenu = CCMenu::menuWithItems(pCloseItem, NULL);
CCMenuItem *down = CCMenuItemFont::itemFromString("down", this, menu_selector(ControlLayer::menuCallBackMove));
//new
CCMenuItemImage *pCloseItem = CCMenuItemImage::create
CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);
CCMenuItem *down = CCMenuItemFont::create("down", this, menu_selector(ControlLayer::menuCallBackMove));

//old
map = CCTMXTiledMap::tiledMapWithTMXFile("0.tmx");
//new
map = CCTMXTiledMap::create("0.tmx");

2.2 取消了CCMutableArray，借用CCArray来代替。遍历方式也变了

CCMutableArray使用有点像stl 中的vector，需要定义一个类型，CCArray全是CCObject,需要用什么类型都要转换。遍历数组方式也变了，之前的像stl中的iterator，升级后使用CCARRAY_FOREACH宏。

//old
enemyArray = new CCMutableArray<Enemy*>();
CCMutableArray<Enemy*>::CCMutableArrayIterator  iter;
for (iter = enemyArray->begin(); iter != enemyArray->end(); ++iter) {
	enemy = *iter;
}
//new
enemyArray = new CCArray();
CCObject *arrayItem;
CCARRAY_FOREACH(enemyArray,arrayItem){
	enemy = (Enemy *)arrayItem;
}

2.3CCMutableDictionary换成CCDictionary

这个也变化较大，感觉cocos2d-x慢慢去掉了C++的stl风格。

//old
teleportDict = new CCMutableDictionary<int, Teleport*>();
//获取对象层内的所有对象
CCMutableArray<CCStringToStringDictionary*> * objects = group->getObjects();
CCStringToStringDictionary* dict;
	CCMutableArray<CCStringToStringDictionary*>::CCMutableArrayIterator it;
	//遍历所有对象
	for( it = objects->begin(); it != objects->end(); it++) 
	{
		dict = (*it);
		int x = dict->objectForKey(key)->toInt();
		CCString *type = dict->objectForKey(key);
	}
	
//new
teleportDict = CCDictionary::create();
teleportDict->retain();	
//获取对象层内的所有对象
	CCArray *objects = group->getObjects();
CCObject* objectItem = NULL;
	//遍历所有对象
	CCARRAY_FOREACH(objects,objectItem)
	{
		CCDictionary *dict = (CCDictionary*)objectItem;
		int x = ((CCString*)dict->objectForKey(key))->floatValue();
		CCString *type =(CCString*) dict->objectForKey(key);
    }	

2.4cocos2d::ccTime统一用float进行代替。

//old
void Hero::updateOpenDoorAnimation(ccTime dt)
//new
void Hero::updateOpenDoorAnimation(float dt)	

2.5一些get、set函数发生改变，比如setIsVisible变成setVisible等；

//old
fightSprite->setIsVisible(false);
//new
fightSprite->setVisible(false);
