一些零碎的代码，便于以后查找

1.添加动画

 1 //添加动画帧
 2 CCAnimation* animation = CCAnimation::create();
 3 for(int i = 1; i< 6;i++)
 4 {
 5   char imgsName[100] = {0};
 6   sprinft(imgsName,”img_%d.png”,i);
 7   animation->addSpriteFrameWithFileName(imgsName);
 8 }
 9 animation->setDelayPerUnit(1.0f);
10 animation->setRestoreOriginalFrame(true);
11 animation->setLoop(-1);
12 //使用动画帧创建动画
13 CCAnimate* animate = CCAnimate::create(animation);
14 this->runAction(animate);

2.替换CCSprite的纹理

setTexture(CCTexture2D)

3.Touch事件处理

bool SoundSprite::ccTouchBegan(cocos2d::CCTouch *touch, cocos2d::CCEvent *event)
{
    CCPoint touchPoint = convertToNodeSpace(touch->getLocation());
    CCRect rect = CCRect(getPositionX() - getContentSize().width * getAnchorPoint().x,
                         getPositionY() - getContentSize().height * getAnchorPoint().y,
                         getContentSize().width, getContentSize().height);
    rect.origin = CCPointZero;
    bool isTouchedIn = rect.containsPoint(touchPoint);
    if (isTouchedIn) {
        CCLog("SoundSprite::ccTouchBegan");
        m_PlaySound = !m_PlaySound;
        this->initWithFile(m_PlaySound?I_FARM_SOUND_ON:I_FARM_SOUND_OFF);
        return true;
    }
    return false;
}
