如何使用c++在cocos2d-x ios游戏中让精灵像青蛙一样跳跃

Question

我正在尝试将精灵制作为青蛙，它将从屏幕顶部出现并在 y 轴 =0 处向下移动到底部。它作为普通 CCMoveTo 工作正常，但我希望在跳跃后青蛙应该休息 1 秒钟，然后再跳。移动有某种延迟。谁能告诉我这个。我也附上我的代码。 我的青蛙动画是从 fly1.png 到 fly5.png。我只想在每次移动后有一个延迟，或者我们可以说我只想在每次延迟 1 秒后调用 CCMove，直到青蛙到达 y 轴 = 0 任何帮助将不胜感激。谢谢

        Firstly, you have to create a frogJump() function. Then,in frogJump() function add the following code:

        void HelloWorld::frogJump()

        {

        CCJumpTo* jumpTo = CCJumpTo::create(1,ccp(x/6,y/8),y/1.2f,1);

        z->runAction(jumpTo);

        }

        Then, in the init() function add the following line:


       this->scheduleOnce(SEL_SCHEDULE(&HelloWorld::frogJump),0);
  this->schedule(SEL_SCHEDULE(&HelloWorld::frogJump),2);
