贪吃蛇完整代码----GUI

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,this);

    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));
            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

        int keyCode = e.getKeyCode();
        if(keyCode == KeyEvent.VK_SPACE){

            }

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

    @Override
    public void keyTyped(KeyEvent e) {

    }
    @Override

    }


}

小蛇的各个部位参数如下

• 头部尺寸

• 身体尺寸
  

• 食物尺寸
