java使用GUI实现贪吃蛇游戏

java使用GUI实现贪吃蛇游戏

本文实例为大家分享了java使用GUI实现贪吃蛇游戏的具体代码，供大家参考，具体内容如下

整个代码分为三部分

1.游戏开始界面2.data基本图片的添加3.面板，将小蛇画到面板上

这是游戏完整界面

1. 游戏开始界面

public class StartGame {

public static void main(String[] args) {

JFrame frame = new JFrame();

frame.setBounds(10,10,900,720);

frame.setResizable(false);

frame.add(new GamePanel());

frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

frame.setVisible(true);

}

}

2.data数据

public class Data {

private static URL headerURL=Data.class.getResource("statics/header.png");

public static ImageIcon header=new ImageIcon(headerURL);

private static URL upURL=Data.class.getResource("statics/up.png");

private static URL downURL=Data.class.getResource("statics/down.png");

private static URL leftURL=Data.class.getResource("statics/left.png");

private static URL rightURL=Data.class.getResource("statics/right.png");

public static ImageIcon up=new ImageIcon(upURL);

public static ImageIcon down=new ImageIcon(downURL);

public static ImageIcon left=new ImageIcon(leftURL);

public static ImageIcon right=new ImageIcon(rightURL);

private static URL bodyURL=Data.class.getResource("statics/body.png");

public static ImageIcon body=new ImageIcon(bodyURL);

private static URL foodURL=Data.class.getResource("statics/food.png");

public static ImageIcon food=new ImageIcon(foodURL);

}

3.面板绘制

public class GamePanel extends JPanel implements KeyListener, ActionListener {

int length;

int [] snakeX=new int[600];

int [] snakeY=new int[500];

String fx;

int foodx;

int foody;

Random random=new Random();

int score;

boolean isStart=false;

boolean isFail=false;

Timer timer=new Timer(75,thttp://his);

public GamePanel() {

init();

this.setFocusable(true);

this.addKeyListener(this);

timer.start();

}

public void init(){

length=3;

snakeX[0]=100;snakeY[0]=100;

snakeX[1]=75;snakeY[1]=100;

snakeX[2]=50;snakeY[2]=100;

fx ="R";

foodx=25+25*random.nextInt(34);

foody=75+25*random.nextInt(24);

score=0;

}

@Override

protected void paintComponent(Graphics g) {

super.paintComponent(g);

this.setBackground(Color.WHITE);

Data.header.paintIcon(this,g,25,11);

g.fillRect(25,75,850,600);

g.setColor(Color.white);

g.setFont(new Font("微软雅黑",Font.BOLD,18));

g.drawString("长度"+length,750,30);

g.drawString("分数"+score,750,50);

Data.food.paintIcon(this,g,foodx,foody);

if(fx.equals("R")){

Data.right.paintIcon(this,g,snakeX[0],snakeY[0]);

}else if(fx.equals("L")){

Data.left.paintIcon(this,g,snakeX[0],snakeY[0]);

}else if(fx.equals("U")){

Data.up.paintIcon(this,g,snakeX[0],snakeY[0]);

}else if(fx.equals("D")){

Data.down.paintIcon(this,g,snakeX[0],snakeY[0]);

}

//Data.right.paintIcon(this,g,snakeX[0],snakeY[0]);

for (int i = 1; i < length; i++) {

Data.body.paintIcon(this,g,snakeX[i],snakeY[i]);

}

if(isStart==false){

g.setColor(Color.white);

g.setFont(new Font("宋体",Font.BOLD,40));

IJtfbF g.drawString("想玩就嗯空格",300,300);

}

if(isFail){

g.setColor(Color.red);

g.setFont(new Font("微软雅黑",Font.BOLD,40));

g.drawString("人生不能重来，请走好每一步",150,350);

}

}

@Override

public void keyPressed(KeyEvent e) {

int keyCode = e.getKeyCode();

if(keyCode == KeyEvent.VK_SPACE){

if(isFail){

isFail=false;

init();

}else{

isStart=!isStart;

}

repaint();

}

if(keyCode==KeyEvent.VK_UP){

fx="U";

}else if(keyCode==KeyEvent.VK_DOWN){

fx="D";

}else if(keyCode==KeyEvent.VK_LEFT){

fx="L";

}else if(keyCode==KeyEvent.VK_RIGHT){

fx="R";

}

}

@Override

public void actionPerformed(ActionEvent e) {

if(isStart&&isFail==false){

if(foodx==snakeX[0]&&foody==snakeY[0]){

length++;

score+=10;

foodx=25+25*random.nextInt(34);

foody=75+25*random.nextInt(24);

}

for (int i = length-1; i >0 ; i--) {

snakeX[i]=snakeX[i-1];

snakeY[i]=snakeY[i-1];

}

if(fx.equals("R")){

snakeX[0] =snakeX[0]+25;

if(snakeX[0]>850){ snakeX[0]=25; }

}else if(fx.equals("L")){

snakeX[0] =snakeX[0]-25;

if(snakeX[0]<25){ snakeX[0]=850; }

}else if(fx.equals("U")){

snakeY[0]=snakeY[0]-25;

if(snakeY[0]<75){snakeY[0]=650;}

}else if(fx.equals("D")){

snakeY[0]=snakeY[0]+25;

if(snakeY[0]>650){snakeY[0]=75;}

}

for (int i = 1; i < length; i++) {

if(snakeY[0]==snakeY[i]&&snakeX[0]==snakeX[i]){

isFail=true;

}

}

repaint();

}

timer.start();

}

@Override

public void keyTyped(KeyEvent e) {

}

@Override

public void keyReleased(KeyEvent e) {

}

}
