3.x vector的用法

#include<vector>

//struct

struct GOLD_STRUCT

{

    Sprite  * goldspSprite;

    int goldValue;

};

//声明一个GOLD_STRUCT的vector

CC_SYNTHESIZE(std::vector<GOLD_STRUCT>, goldVector, GoldVector);

//将对象放入到vector容器中

void HelloWorld::initdaoju()

{

    std::vector<GOLD_STRUCT>goldVector;

    _spriteBatchNode = SpriteBatchNode::create("close.png");

    m_GameMap->addChild(_spriteBatchNode);

    TMXObjectGroup *group = m_GameMap->objectGroupNamed("gold");

    auto m_Golds = group->getObjects();

    for (int i = 0; i < m_Golds.size(); i++)

    {

        auto& obj = m_Golds.at(i);

        ValueMap& dict = obj.asValueMap();

        //std::string name = dict["name"].asString();

        float x = dict["x"].asFloat();

        float y = dict["y"].asFloat();

        float width = dict["width"].asFloat();

        float height = dict["height"].asFloat();

        Rect box = Rect(x, y, width, height);

       _sprite = Sprite::create("close.png");

        _spriteBatchNode->addChild(_sprite, tag);

        _sprite->setPosition(ccp(x, y));

        GOLD_STRUCT _gs;

        _gs.goldspSprite = _sprite;

        //根据配置文件或者plist文件来加载不同的金币数目

        _gs.goldValue = 100;

        goldVector.push_back(_gs);

    }

    m_Player->setGoldVector(goldVector);

}

//遍历vector中的元素

for (unsigned int i = 0; i < goldVector.size(); i++)

    {

        GOLD_STRUCT  gs = goldVector[i];

        mSprite->boundingBox();

        gs.goldspSprite->boundingBox();

        if (mSprite->boundingBox().intersectsRect(gs.goldspSprite->boundingBox()))

        {

            gs.goldspSprite->removeFromParentAndCleanup(true);

            goldVector.erase(goldVector.begin());

            CCLOG("1111");

        }

    }
