本文实例讲述了java编写的简单移动方块小游戏代码。分享给大家供大家参考，具体如下：

运行效果截图如下：

第一次用java编写图形化的界面，还是有些青涩。。以后继续努力！！具体代码如下：

//Little Box Game by AlexYui

//Game.java By 1093710210@ HIT

import javax.swing.*;

import java.awt.event.*;

import java.awt.geom.*;

import java.awt.*;

import java.util.*;

public class Game{

public static void main(String[] agrs){

MyFrame gameframe = new MyFrame();

gameframe.setTitle("Java Box Game By AlexYui");

gameframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

gameframe.setVisible(true);

}

}

//框架

class MyFrame extends JFrame {

private int flag = 0;

protected double x[] = {0,0,270,0,270};

protected double y[] = {0,0,0,270,270};

protected int winner[]={0,0,0,0,0};

public static final int DEFAULT_WIDTH = 317;

public static final int DEFAULT_HEIGHT = 339;

public MyFrame(){

MyPanel a = new MyPanel();

addKeyListener(new MyKeyListener());

this.add(a);

setSize(DEFAULT_WIDTH,DEFAULT_HEIGHT);

}

class MyPanel extends JPanel{

public MyPanel(){}

public void paint(Graphics g){

super.paint(g);

Graphics2D g2 = (Graphics2D)g;

Rectangle2D rect1 = new Rectangle2D.Double(x[1],y[1],30f,30f);

Rectangle2D rect2 = new Rectangle2D.Double(x[2],y[2],30f,30f);

Rectangle2D rect3 = new Rectangle2D.Double(x[3],y[3],30f,30f);

Rectangle2D rect4 = new Rectangle2D.Double(x[4],y[4],30f,30f);

//画中间的四个方框

g2.setPaint(Color.RED);

g2.drawRect(120,120 ,30,30);

g2.drawRect(120,150 ,30,30);

g2.drawRect(150,120 ,30,30);

g2.drawRect(150,150 ,30,30);

//填充四个角上的方块

g2.setPaint(Color.BLUE);

if(winner[1] == 0)g2.fill(rect1);

if(winner[2] == 0)g2.fill(rect2);

if(winner[3] == 0)g2.fill(rect3);

if(winner[4] == 0)g2.fill(rect4);

g2.setPaint(Color.RED);

//将已经选择的方块涂成红色

if(flag == 1) g2.fill(rect1);

if(flag == 2) g2.fill(rect2);

if(flag == 3) g2.fill(rect3);

if(flag == 4) g2.fill(rect4);

g2.setPaint(Color.BLUE);

if(winner[1] == 1)g2.fill(rect1);

if(winner[2] == 1)g2.fill(rect2);

if(winner[3] == 1)g2.fill(rect3);

if(winner[4] == 1)g2.fill(rect4);

g2.setPaint(Color.RED);

if(winner[1] == 1 && winner[2] == 1 && winner[3] == 1 && winner[4] == 1)

g2.drawString("Succes! You Won!",100,75);

//保持边框的颜色

g2.drawRect(120,120 ,30,30);

g2.drawRect(120,150 ,30,30);

g2.drawRect(150,120 ,30,30);

g2.drawRect(150,150 ,30,30);

repaint();

}

}

class MyKeyListener implements KeyListener{

//overide

public void keyPressed(KeyEvent event){

int keyCode = event.getKeyCode();

if(keyCode == KeyEvent.VK_1){flag = 1;}

if(keyCode == KeyEvent.VK_2){flag = 2;}

if(keyCode == KeyEvent.VK_3){flag = 3;}

if(keyCode == KeyEvent.VK_4){flag = 4;}

if(keyCode == KeyEvent.VK_UP){move(0,-30,flag);win();}

if(keyCode == KeyEvent.VK_DOWN){move(0,30,flag);win();}

if(keyCode == KeyEvent.VK_LEFT){move(-30,0,flag);win();}

if(keyCode == KeyEvent.VK_RIGHT){move(30,0,flag);win();}

}

public void keyReleased(KeyEvent event){}

public void keyTyped(KeyEvent event){}

}

//用于判别基本规则，移动方块

void move(int mx,int my,int mflag){

int i;

boolean teller = false;

x[mflag] +=mx;

y[mflag] +=my;

if(! ((x[flag] >= 0 && x[flag]<=270)&&(y[flag] >= 0 && y[flag]<=270))){

x[mflag] -=mx;

y[mflag] -=my;

}

for(i = 1;i<5;i++){

if(mflag != i)

if(x[mflag] == x[i] && y[mflag] == y[i])

teller = true;

}

if(teller == true){

x[mflag] -= mx;

y[mflag] -= my;

}

}

//用于判别已经进入符合条件区域的方块

void win(){

int j1,j2;

for(j1=1;j1<5;j1++)

if((x[j1]<=150&&x[j1]>=120)&&(y[j1]<=150&&y[j1]>=120))

winner[j1]=1;

for(j2=1;j2<5;j2++)

if(!((x[j2]<=150&&x[j2]>=120)&&(y[j2]<=150&&y[j2]>=120)))

winner[j2]=0;

}

}

希望本文所述对大家Java程序设计有所帮助。
