cocos2dx 颜色渐变

 ccColor3B col = m_pSprite->getColor();
 //获取需要变的颜色
 CCFiniteTimeAction * tinto = CCTintTo ::create(3, 255, 255, 0);
 //获取自身颜色
 CCFiniteTimeAction * tinto1 = CCTintTo ::create(3, col.r, col.g, col.b);
 //组成队列
 CCActionInterval* tintActions = CCSequence::create(tinto,tinto1,NULL);
 //放入循环
 CCRepeatForever *item = CCRepeatForever::create(tintActions );
 //渐变颜色自身与实际切换
 m_pSprite->runAction( item);
