auto size = Director::sharedDirector()->getVisibleSize();
auto pursuer1 = Sprite::create(“CloseSelected.png”);
pursuer1->setPosition(0, size.height/2-40);
this->addChild(pursuer1);
auto move = RepeatForever::create(Sequence::create(MoveTo::create(10, ccp(size.width, size.height/2-40)), MoveTo::create(10.0, ccp(0, size.height / 2-40)), NULL));
pursuer1->runAction(move);
auto pursuer2 = Sprite::create(“CloseNormal.png”);
pursuer2->setPosition(size.width, size.height/2-40);
this->addChild(pursuer2);
pursuer2->runAction(Follow::create(pursuer1));
精灵2跟随精灵1，为什么启动后精灵2在屏幕中间的偏下而不是pursuer2->setPosition(size.width, size.height/2-40);设定的位置；
希望有大神指点下疑惑，Follow用法
