不想再重写一遍了。简短点。这节课要实现和学习的内容有：（假设想看具体内容的请戳上面的连接，看下视频的教程更好）
1.人物的运动状态控制——跳起。受伤，死亡推断。和怪物的打斗逻辑
2.碰撞检測（我们这个游戏因为是横版且人物仅仅可以在左右走。因此变化的坐标仅仅有X，所以检測起来也是非常easy的。
）
很多其它关于碰撞检測的东西见：http://shahdza.blog.51cto.com/2410787/1548097
3.关卡的失败和胜利推断以及相关的场景的分析和实现
4.暂停功能场景的分析和实现
关于跳起的动作这里简单的解释一下。
由于要模拟人物跳起后的一个近抛物线的运动轨迹，因此我们这里让Y轴的速度不断变化，而X轴不变，这个原理学过高中物理应该都明确。
这个函数就是：
float velocity = 0.0f; // 跳起速度 float getVelocity(); // 获取跳跃的速度
逻辑的东西解释起来比較复杂，先把代码贴出来吧。

关于暂停场景的实现例如以下，由于暂停要实现一个动态的开关效果，并且背景是游戏暂停的场景。所以做了一个截图，传递给这个场景，代码实现例如以下：
/*!
* \file PauseLayer.h
*
* \author SuooL
* \date 六月 2015
*
* 暂停界面
*/
#ifndef __PauseLayer__H__
#define __PauseLayer__H__
#include "cocos2d.h"
#include "extensions/cocos-ext.h"
USING_NS_CC;
using namespace cocos2d::extension;
class PauseLayer : public Layer {
public:
static Scene* createScene(RenderTexture* rt);
virtual bool init();
CREATE_FUNC(PauseLayer);
Sprite* spriteOn;
Sprite* spriteDown;
void musicSet(Ref* pSender);
private:
};
#endif

代码的凝视已经很具体了。
