Java实现推箱子小游戏

一、整体框架

二、游戏效果图

三、推箱子四大类

1. GameFrame类

2. Map类

3. MapFactory类

4. Sound类

四、游戏分析

1.游戏操作

2.数组解读

五、单独窗体播放音乐（wav格式）

1.GameFrame类

2. 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）

三、推箱子四大类

package 推箱子;
import javax.sound.midi.*;
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();
    }   
    sign = true;
  } 
  void mystop(){
    midi.stop();
    midi.close();
    sign=false;
  }
  boolean isplay(){
    return sign;
  }
  void setMusic(String e){
    file=e;
  }
}

四、游戏分析

1.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。

2.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、单独窗体播放音乐（wav格式）

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）
