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！

言归正传，我们来看游戏代码
代码直接复制粘贴就能运行（素材包放在项目src目录下）
二、推箱子四大类

Sound类

import java.io.File;
import java.io.IOException;
public class Sound {
String path = new String("E:/kkkkk/推箱子/src/img/");
String file = new String("nor.mid");
Sequence seq;
Sequencer midi;
boolean sign;
//加载音乐
public void loadSound(){
try {
seq = MidiSystem.getSequence(new File(path+file));
midi = MidiSystem.getSequencer();
midi.open();
midi.setSequence(seq);
midi.start();
midi.setLoopCount(Sequencer.LOOP_CONTINUOUSLY);
} catch (InvalidMidiDataException | IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MidiUnavailableException e) {
// TODO Auto-generated catch block
e.printStackTrace();

midi.close();

}
}
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）；
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）
