Cocos2d-x 和处理触摸事件[重复]

Question

我在屏幕上有我的精灵，我有一个存储每个精灵的向量。

CCSprite* 可以处理触摸事件吗？还是只是 CCLayer*？

确定触摸了哪个精灵的最佳方法是什么？我是否应该存储精灵所在位置的坐标（在精灵类中），当我得到事件时，通过查看向量并获取每个精灵的当前坐标来查看用户触摸的位置是否是精灵所在的位置？ 更新：我继承了 CCSprite：

class Field : public cocos2d::CCSprite, public cocos2d::CCTargetedTouchDelegate

我实现功能：

    cocos2d::CCRect rect();

    virtual void onEnter();
    virtual void onExit();

    bool containsTouchLocation(cocos2d::CCTouch* touch);
    virtual bool ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);

    virtual void touchDelegateRetain();
    virtual void touchDelegateRelease();

我把CCLOG语句放在每一个里，我不打它们！

当我触摸 CCLayer 时，这个精灵就打开了，尽管我确实点击了实现图层的类中的那些精灵并将这些精灵放在图层上。

更新：我一直在尝试的代码：

Field* Field::createWithLocation(cocos2d::CCPoint p)
{
    Field* f = new Field();
    f->autorelease();
    f->initWithLocation(p);
    return f;
}

void Field::initWithLocation(cocos2d::CCPoint p)
{
    setFieldCenterPoint(p);
    setFieldGraphicName(FIELD::fieldIconFileName);

    setFieldSprite(cocos2d::CCSprite::create(getFieldGraphicName().c_str()));
    getFieldSprite()->setPosition(ccp(getFieldCenterPoint().x, getFieldCenterPoint().y));

    setFieldSize(getFieldSprite()->getContentSize());
}

cocos2d::CCRect Field::rect()
{
    cocos2d::CCSize s = getFieldSprite()->getTexture()->getContentSize();
    return cocos2d::CCRectMake(-s.width / 2, -s.height / 2, s.width, s.height);
}

void Field::onEnter()
{
    CCLOG("In onEnter");
    cocos2d::CCDirector* pDirector = cocos2d::CCDirector::sharedDirector();
    pDirector->getTouchDispatcher()->addTargetedDelegate(this, 0, true);
    //_dir->Instance()->getDirector()->getTouchDispatcher()->addTargetedDelegate(this, 0, true);
    cocos2d::CCSprite::onEnter();
}

void Field::onExit()
{
    CCLOG("In onExit");
    cocos2d::CCDirector* pDirector = cocos2d::CCDirector::sharedDirector();
    pDirector->getTouchDispatcher()->removeDelegate(this);
    //_dir->Instance()->getDirector()->getTouchDispatcher()->removeDelegate(this);
    cocos2d::CCSprite::onExit();
}

bool Field::containsTouchLocation(cocos2d::CCTouch* touch)
{
    return rect().containsPoint(convertTouchToNodeSpaceAR(touch));
}

bool Field::ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
    CCLOG("In ccTouchBegan");

    return true;
}

void Field::ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
    CCLOG("In ccTouchMoved");
}

void Field::ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
     CCLOG("In ccTouchEnded");
}

void Field::touchDelegateRetain()
{
    this->retain();
}

void Field::touchDelegateRelease()
{
    this->release();
}
