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）

2. Map类
package 推箱子; public class Map { int manX = 0; int manY = 0; byte map[][]; int grade; public Map(int manX,int manY,byte[][] map){ this.manX = manX; this.manY = manY; int row = map.length; int column = map[0].length; byte temp[][] = new byte[row][column]; for(int i=0;i<row;i++){ for(int j=0;j<column;j++){ temp[i][j] = map[i][j]; } } this.map = temp;//避免直接引用 } public Map(int manX,int manY,byte[][] map,int grade){ this(manX,manY,map); this.grade = grade; } //人物X坐标 public int getManX(){ return manX; } //人物Y坐标 public int getManY(){ return manY; } //地图数组 public byte[][] getMap(){ return map; } //关卡 public int getGrade(){ return grade; } }
3. MapFactory类
package 推箱子; public class MapFactory {//地图数据类 static byte map[][][] = { { {0,0,1,1,1,0,0,0}, {0,0,1,4,1,0,0,0}, {0,0,1,9,1,1,1,1}, {1,1,1,2,9,2,4,1}, {1,4,9,2,5,1,1,1}, {1,1,1,1,2,1,0,0}, {0,0,0,1,4,1,0,0}, {0,0,0,1,1,1,0,0} }, { {1,1,1,1,1,0,0,0,0}, {1,9,9,5,1,0,0,0,0}, {1,9,2,2,1,0,1,1,1}, {1,9,2,9,1,0,1,4,1}, {1,1,1,9,1,1,1,4,1}, {0,1,1,9,9,9,9,4,1}, {0,1,9,9,9,1,9,9,1}, {0,1,9,9,9,1,1,1,1}, {0,1,1,1,1,1,0,0,0} }, { {1,1,1,1,1,0,0,0,0}, {1,9,9,9,1,1,0,0,0}, {1,9,2,9,9,1,0,0,0}, {1,1,9,2,9,1,1,1,1}, {0,1,1,1,5,4,9,9,1}, {0,0,1,9,9,4,1,9,1}, {0,0,1,9,9,9,9,9,1}, {0,0,1,1,1,1,1,1,1} }, { {0,0,1,1,1,1}, {0,1,1,9,9,1}, {1,1,9,2,9,1}, {1,4,2,9,5,1}, {1,2,4,9,1,1}, {1,4,9,1,1,0}, {1,1,1,1,0,0} }, { {1,1,1,1,1,1}, {1,9,5,9,9,1}, {1,9,2,9,9,1}, {1,2,9,1,1,1}, {1,4,9,4,1,0}, {1,1,1,1,1,0} }, { {0,0,0,1,1,1,1,0,0}, {0,0,1,1,9,9,1,1,0}, {1,1,1,9,5,2,4,1,1}, {1,9,9,9,9,2,4,9,1}, {1,9,9,9,1,2,4,9,1}, {1,1,1,1,1,9,1,9,1}, {0,0,0,0,1,9,9,9,1}, {0,0,0,0,1,1,1,1,1} }, { {0,0,0,0,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0},//19行 {0,0,0,0,1,9,9,9,1,0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,1,2,9,9,1,0,0,0,0,0,0,0,0,0,0}, {0,0,1,1,1,9,9,2,1,1,0,0,0,0,0,0,0,0,0}, {0,0,1,9,9,2,9,2,9,1,0,0,0,0,0,0,0,0,0}, {1,1,1,9,1,9,1,1,9,1,0,0,0,1,1,1,1,1,1}, {1,9,9,9,1,9,1,1,9,1,1,1,1,1,9,9,4,4,1}, {1,9,2,9,9,2,9,9,9,9,9,9,9,9,9,9,4,4,1}, {1,1,1,1,1,9,1,1,1,9,1,5,1,1,9,9,4,4,1}, {0,0,0,0,1,9,9,9,9,9,1,1,1,1,1,1,1,1,1}, {0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0} }, { {1,1,1,1,1,1,1,1,1,1,1,1,0,0},//14行 {1,4,4,9,9,1,9,9,9,9,9,1,1,1}, {1,4,4,9,9,1,9,2,9,9,2,9,9,1}, {1,4,4,9,9,1,2,1,1,1,1,9,9,1}, {1,4,4,9,9,9,9,5,9,1,1,9,9,1}, {1,4,4,9,9,1,9,1,9,9,2,9,1,1}, {1,1,1,1,1,1,9,1,1,2,9,2,9,1}, {0,0,1,9,2,9,9,2,9,2,9,2,9,1}, {0,0,1,9,9,9,9,1,9,9,9,9,9,1}, {0,0,1,1,1,1,1,1,1,1,1,1,1,1} }, { {0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,0},//17行 {0,0,0,0,0,0,0,0,1,9,9,9,9,9,5,1,0}, {0,0,0,0,0,0,0,0,1,9,2,1,2,9,1,1,0}, {0,0,0,0,0,0,0,0,1,9,2,9,9,2,1,0,0}, {0,0,0,0,0,0,0,0,1,1,2,9,2,9,1,0,0}, {1,1,1,1,1,1,1,1,1,9,2,9,1,9,1,1,1}, {1,4,4,4,4,9,9,1,1,9,2,9,9,2,9,9,1}, {1,1,4,4,4,9,9,9,9,2,9,9,2,9,9,9,1}, {1,4,4,4,4,9,9,1,1,1,1,1,1,1,1,1,1}, {1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0} }, { {0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0},//19行 {0,0,0,0,0,1,1,1,1,0,1,9,9,1,0,0,0,0,0}, {0,0,0,1,1,1,9,5,1,1,1,2,9,1,0,0,0,0,0}, {0,0,1,1,9,9,9,9,9,9,2,9,9,1,0,0,0,0,0}, {0,1,1,9,9,2,9,2,2,1,1,9,1,1,0,0,0,0,0}, {0,1,9,9,1,2,1,1,9,9,9,9,9,1,0,0,0,0,0}, {0,1,9,1,9,2,9,2,2,9,1,9,1,1,1,0,0,0,0}, {0,1,9,9,9,2,9,1,9,9,1,9,2,9,1,1,1,1,1}, {1,1,1,1,9,9,9,9,1,9,9,2,2,9,1,9,9,9,1}, {1,1,1,1,9,1,1,9,2,9,9,9,9,9,9,9,9,9,1}, {1,4,9,9,9,9,1,1,1,9,9,1,1,1,1,1,1,1,1}, {1,4,4,9,4,4,1,0,1,1,1,1,0,0,0,0,0,0,0}, {1,4,4,4,1,4,1,0,0,0,0,0,0,0,0,0,0,0,0}, {1,4,4,4,4,4,1,0,0,0,0,0,0,0,0,0,0,0,0}, {1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0} } }; static int count = map.length; public static byte[][] getMap(int grade){ byte[][] temp; if(grade>=0&&grade<count) { temp = map[grade]; }else { temp = map[0]; } int row = temp.length; int column = temp[0].length; byte[][] result = new byte[row][column];//备份关卡版本 for(int i=0;i<row;i++){ for(int j=0;j<column;j++){ result[i][j] = temp[i][j]; } } return result; } public static int getCount(){ return count; } }
4. Sound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）
1.GameFrame类
