基于Java的游戏“贪吃蛇的设计和实现
以下是使用Java和Eclipse IDE制作贪吃蛇游戏的步骤:
1.创建一个新的Java项目并命名为SnakeGame。
2.创建一个新的包并命名为snakegame。
3.在snakegame包中创建一个新的类并命名为Snake。
4.在Snake类中添加以下代码:
```java
package snakegame;
public class Snake {
// Add code here
}
```
5.在Snake类中添加以下属性:
```java
private int x;
private int y;private int size;
private int direction;
```
6.在Snake类中添加以下方法:
```java
public void move() {
// Add code here
}
public void grow() {
// Add code here
}
public boolean checkCollision() {
// Add code here
return false;
}
```
7.在Snake类中添加以下构造函数:
```java
public Snake(int x, int y, int size, int direction) {
this.x = x;
this.y = y;
this.size = size;
this.direction = direction;
}
```
8.在Snake类中添加以下getter和setter方法:
```java
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
public int getSize() {
return size;
}
public void setSize(int size) {
this.size = size;
}
public int getDirection() {
return direction;
}
public void setDirection(int direction) {
this.direction = direction;
}
```
9.在snakegame包中创建一个新的类并命名为Game。
10.在Game类中添加以下代码:
```java
package snakegame;
import javax.swing.JFrame;
public class Game extends JFrame {
// Add code here
}
```
11.在Game类中添加以下属性:
```java
private Snake snake;
private boolean running;
```
12.在Game类中添加以下方法:
```java
public void start() {
// Add code here
}
public void stop() {
// Add code here
}
public void run() {
// Add code here
}
public void update() {
// Add code here
}
public void paint(Graphics g) {
// Add code here
}
```
13.在Game类中添加以下构造函数:
```java
public Game() {
snake = new Snake(0, 0, 10, Snake.RIGHT);
running = true;
}
```
14.在Game类中添加以下getter和setter方法:
```java
public Snake getSnake() {
return snake;
}
public void setSnake(Snake snake) {
this.snake = snake;
}
public boolean isRunning() {
return running;
}
public void setRunning(boolean running) {
this.running = running;
}
```
15.在Game类中添加以下main方法:
```java
public static void main(String[] args) {
Game game = new Game();
game.setSize(500, 500);
game.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
game.setVisible(true);
game.start();
}
```
16.在Game类中添加以下键盘监听器:
```java
private class Keyboard extends KeyAdapter {
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();
if (key == KeyEvent.VK_LEFT) {
snake.setDirection(Snake.LEFT);
} else if (key == KeyEvent.VK_RIGHT) {
snake.setDirection(Snake.RIGHT);
} else if (key == KeyEvent.VK_UP) {
snake.setDirection(Snake.UP);
} else if (key == KeyEvent.VK_DOWN) {
snake.setDirection(Snake.DOWN);
}
}
}
```
17.在Game类的构造函数中添加以下代码:
```java
addKeyListener(new Keyboard());
setFocusable(true);
```
18.在Game类的paint方法中添加以下代码:
```java
super.paint(g);
Graphics2D g2d = (Graphics2D) g;
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2d.setColor(Color.BLACK);
g2d.fillRect(0, 0, getWidth(), getHeight());
g2d.setColor(Color.WHITE);
g2d.drawString("Score: " + snake.getSize(), 10, 20);
g2d.setColor(Color.GREEN);
g2d.fillRect(snake.getX(), snake.getY(), snake.getSize(), snake.getSize());
```
19.在Game类的update方法中添加以下代码:
```java
snake.move();
if (snake.checkCollision()) {
running = false;
}
```
20.在Game类的run方法中添加以下代码:
```java
while (running) {
update();
repaint();
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
```
21.在Game类的start方法中添加以下代码:
```java
Thread thread = new Thread(this);
thread.start();
```
22.在Game类的stop方法中添加以下代码:
```java
running = false;
```
23.运行程序并开始玩贪吃蛇游戏。
