不想再重写一遍了。简短点，这节课要实现和学习的内容有：（如果想看详细内容的请戳上面的连接，看下视频的教程更好）

技术分享

1.人物的运动状态控制——跳起，受伤，死亡判断，和怪物的打斗逻辑

2.碰撞检测（我们这个游戏由于是横版且人物只能够在左右走，因此变化的坐标只有X，所以检测起来也是很容易的。）

更多关于碰撞检测的东西见：http://shahdza.blog.51cto.com/2410787/1548097

3.关卡的失败和胜利判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。

因为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白。

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较复杂，先把代码贴出来吧。

关于暂停场景的实现如下，因为暂停要实现一个动态的开关效果，而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，代码实现如下：

/*!
 * \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;

	virtual bool init();
	CREATE_FUNC(PauseLayer);

	Sprite* spriteOn;
	Sprite* spriteDown;

	void musicSet(Ref* pSender);

private:

#endif

代码的注释已经非常详细了。如果您有不明白的地方可以留言或者邮箱我：1020935219@qq.com

整个工程的源码已经开源，地址是：https://github.com/SuooL/KungfuBoy

下一课将会说明下打包APK和项目打包过程及打包后会出现的一些问题及其解决的方法。
