c++ - Cocos2d-x 添加标签到扩展 CCNode 在插入到 CCDictionary 时消失

Question

我尝试设置标签并且成功了，但是当我将 CCnode 插入到 CCDictionary 时并尝试获取 CCNode 并检查标签，它是 0。

int tagNum = 242;   
    //Gem is class Gem :public CCNode , public CCTargetedTouchDelegate 
    Gem *thisGem = new Gem();
    thisGem->retain();
    thisGem->setTag(tagNum);
    thisGem->initWithGame(this,zorder);
    int t1 = thisGem->getTag();
    // t1 = 242
    //set in container
    std::string gemID = thisGem->getGemId();
    gemsDictionary->setObject(thisGem,gemID); //gemsDictionary init in the contracture 
    Gem *nextGemTest = (Gem *)gemsDictionary->objectForKey(gemID); 
    int t2 = nextGemTest->getTag();
    // t2 is 0 ???

Answer 1

你可以尝试使用std::map<std::string, Gem *>而不是 CCDictionary
