### Java实现推箱子小游戏 ###

*  一、整体框架
 *  二、游戏效果图
 *  二、推箱子四大类
 *  GameFrame类
 *   *  Map类
     *   *  MapFactory类
         *   *  Sound类
 *  四、游戏分析
 *   *  游戏操作
     *  数组解读
 *  五、wav格式音乐代码
 *   *  GameFrame类
     *  Sound类

文章比较长，请耐心看完。

# 一、整体框架 #

该程序由四个类组成，GameFrame类（程序主体）、Map类（地图基础设置）、MapFactory类（地图构图）、Sound类（添加音乐），下面是程序结构图。

*注意音乐格式要转MIDI序列（直接改文件后缀名不可行，如果想更换背景音乐，建议下载widi进行格式转换）*

# 二、游戏效果图 #

游戏画面没有设置的很炫酷，因为绿色比较护眼。  
正在看这篇博客的你，让眼睛休息一下吧！

# 四、游戏分析 #

## 游戏操作 ##

键盘上下左右键控制人物的移动，按A回到上一关，按D直接进入下一关。

## 数组解读 ##

很多人对这个庞大的数组很好奇，其实呢，它们非常简单，下面我来解读一下。  
0（墙外的空余区域）；1（墙）；2（箱子）；3（箱子位于目标点上）；  
4（目标点）；5（人物向下）；9（空地）；  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80ODcwMTUyMQ_size_16_color_FFFFFF_t_70_pic_center 3]

# 五、wav格式音乐代码 #

由于mid格式比较少见，一般的软件无法实现该格式的转换，所以我们使用javax.sound实现简单的音频播放（只支持AU，RA，WAV格式），相比而言比较大众化。可以自己挑选喜欢的音乐作为背景音乐。  
更新后代码如下（只修改GameFrame类和Sound类）
