Java 小游戏代码

Java作为一门广受欢迎的编程语言，不仅在企业级应用开发中得到了广泛应用，也在游戏开发领域逐渐崭露头角。针对那些对Java编程有一定了解，想要尝试开发自己的小游戏的初学者，本文为大家提供了一份Java小游戏代码大全，其中包含了多个不同类型的小游戏，如扫雷、贪食蛇等。

下面给出一个贪食蛇的代码示例：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Point;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.LinkedList;
import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Snake extends JPanel implements KeyListener {
  private static final long serialVersionUID = -6209907017780465069L;
  private int width = 40;
  private int height = 30;
  private int size = 10;
  private LinkedList
  snake = new LinkedList 
  
   ();
  
 
  private Point food = null;
  private Random random = new Random();
  private int direction = KeyEvent.VK_RIGHT;
  public Snake() {
    JFrame frame = new JFrame("Snake");
    frame.setSize(width * size + 6, height * size + 28);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().add(this);
    frame.addKeyListener(this);
    frame.setResizable(false);
    initSnake();
    initFood();
    frame.setVisible(true);
  }
  public void initSnake() {
    snake.clear();
    snake.add(new Point(5, 0));
    snake.add(new Point(4, 0));
    snake.add(new Point(3, 0));
    snake.add(new Point(2, 0));
  }
  public void initFood() {
    food = new Point(random.nextInt(width), random.nextInt(height));
  }
  public void move() {
    Point head = snake.getFirst();
    Point next = new Point(head.x, head.y);
    switch (direction) {
    case KeyEvent.VK_UP:
      next.y--;
      break;
    case KeyEvent.VK_DOWN:
      next.y++;
      break;
    case KeyEvent.VK_LEFT:
      next.x--;
      break;
    case KeyEvent.VK_RIGHT:
      next.x++;
      break;
    }
    if (next.x < 0 || next.x >= width || next.y < 0 || next.y >= height || snake.contains(next)) {
      initSnake();
      return;
    }
    snake.addFirst(next);
    if (next.equals(food)) {
      initFood();
    } else {
      snake.removeLast();
    }
  }
  @Override
  public void paint(Graphics g) {
    g.setColor(Color.BLACK);
    g.fillRect(0, 0, width * size, height * size);
    g.setColor(Color.WHITE);
    for (Point point : snake) {
      g.fillRect(point.x * size, point.y * size, size, size);
    }
    g.setColor(Color.RED);
    g.fillRect(food.x * size, food.y * size, size, size);
  }
  public static void main(String[] args) {
    new Snake().run();
  }
  public void run() {
    while (true) {
      try {
        Thread.sleep(100);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }
      move();
      repaint();
    }
  }
  @Override
  public void keyPressed(KeyEvent e) {
    int key = e.getKeyCode();
    if ((key == KeyEvent.VK_UP || key == KeyEvent.VK_DOWN || key == KeyEvent.VK_LEFT
        || key == KeyEvent.VK_RIGHT) && Math.abs(key - direction) != 2)
      direction = key;
    
  }
  @Override
  public void keyReleased(KeyEvent e)
  
  @Override
  public void keyTyped(KeyEvent e)
  
}

此处为贪食蛇的核心代码实现部分，具体效果请见运行结果。
