TargetedAction

//这里的重点是girl应该怎样才能在boy做完action后执行她的动作呢？有以下几种办法  
//1、用延迟的DelayTime来实现，也就是boy运动完后延迟几秒，然后让girl运动  
  
//延迟2.5s，用1s时间跳了3次，跳跃高度100像素，并且向右移动了30像素  
girl->runAction(Sequence::create(DelayTime::create(2.5f),JumpBy::create(1.0f,Point(30,0),100,3),NULL));  
  
  
//2、用回调函数实现，当boy完成后，写一个lambda表达式来实现girl要做的动作（lambda表达式的使用可以参考我上一篇博客）  
  
boy->runAction(Sequence::create(RotateBy::create(1.0f,360),ScaleTo::create(1.0f,1.2f),  
        CallFunc::create([=]()  
        {  
            //用1s时间跳了3次，跳跃高度100像素，并且向右移动了30像素  
            girl->runAction(JumpBy::create(1.0f,Point(30,0),100,3));  
        }),NULL));  
  
          
//3、用现成的接口TargetedAction();  
  
auto jump = JumpBy::create(1.0f,Point(30,0),100,3);//先写一个跳跃的动作  
auto targetAct = TargetedAction::create(girl,jump);//写一个目标动作，将动作执行人girl和要执行的动作jump放入其中  
//将girl的目标动作放入boy的sequence里去  
boy->runAction(Sequence::create(RotateBy::create(1.0f,360),ScaleTo::create(1.0f,1.2f),targetAct,NULL));
