MoveTo：把某一CCSprite移动到某个位置MoveBy:把某一CCSprite移动一段距离,它有一个方法reverse，它让对象按原路径返回

void MyActionMoveToLayer::initLayer() {    /*    *@MoveTo,移动到某个Point    */    CCSize size = CCDirector::sharedDirector()->getWinSize();    CCSprite *spriteMoveTo = CCSprite::create("snow.png");    spriteMoveTo->setPosition(ccp(size.width / 2.0f, size.height / 2.0f));    this->addChild(spriteMoveTo, 1);    CCActionInterval *forward = CCMoveTo::create(4, ccp(300, 300));    spriteMoveTo->runAction(forward);    /*    *MoveBy,移动一段距离    */    CCSprite *spriteMoveBy = CCSprite::create("snow.png");    spriteMoveBy->setPosition(ccp(size.width / 4.0f, size.height / 4.0f));    this->addChild(spriteMoveBy, 1);    CCActionInterval *forwardBy = CCMoveBy::create(2, ccp(200, 300));    CCActionInterval *backBy = forwardBy->reverse();    CCAction *action = CCRepeat::create(dynamic_cast<CCFiniteTimeAction *>(CCSequence::create(forwardBy, backBy, NULL)), 4);    spriteMoveBy->runAction(action);}
