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）

【Cocos游戏实战】功夫小子第七课之游戏主功能场景逻辑功能和暂停功能场景的分析和实现

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： 

/*!

 *
 * \author SuooL
 * \date 六月 2015
 *
 * 暂停界面

#ifndef __PauseLayer__H__
#define __PauseLayer__H__

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。
