java实现雷霆战机小游戏

实现一个简单的雷霆战机小游戏（类似于经典的射击游戏）是一个很好的编程练习项目。这个游戏的目标是控制一架飞机躲避障碍物并击落敌机。以下是用Java实现一个基本的雷霆战机小游戏的步骤和详细讲解。

1. 游戏设计

首先，我们需要设计游戏的基本元素：

玩家飞机（Player Plane）：玩家控制的飞机，可以用箭头键移动。
敌机（Enemy Plane）：从屏幕顶部向下移动的敌机，玩家需要击落它们。
子弹（Bullet）：玩家飞机发射的子弹，用于击落敌机。
背景（Background）：游戏的背景图像。

2. 实现步骤

以下是实现雷霆战机小游戏的详细步骤：

2.1 创建游戏窗口

首先，创建一个Java窗口来显示游戏内容。

import javax.swing.JFrame;public class ThunderJetGame extends JFrame {public ThunderJetGame() {initUI();}private void initUI() {add(new GameBoard());setSize(800, 600);setTitle("Thunder Jet Game");setDefaultCloseOperation(EXIT_ON_CLOSE);setLocationRelativeTo(null);}public static void main(String[] args) {javax.swing.SwingUtilities.invokeLater(() -> {ThunderJetGame ex = new ThunderJetGame();ex.setVisible(true);});}
}

2.2 创建游戏面板

接下来，创建一个游戏面板来绘制游戏元素并处理游戏逻辑。

import javax.swing.JPanel;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.util.ArrayList;
import java.util.List;
import javax.swing.Timer;public class GameBoard extends JPanel implements ActionListener {private Timer timer;private List<EnemyPlane> enemyPlanes;private PlayerPlane playerPlane;private List<Bullet> bullets;public GameBoard() {initGame();}private void initGame() {enemyPlanes = new ArrayList<>();bullets = new ArrayList<>();playerPlane = new PlayerPlane(400, 500);addKeyListener(new TAdapter());setFocusable(true);setBackground(Color.BLACK);timer = new Timer(30, this);timer.start();}@Overridepublic void actionPerformed(ActionEvent e) {updateGame();repaint();}private void updateGame() {playerPlane.move();for (Bullet bullet : bullets) {bullet.move();}bullets.removeIf(Bullet::isOutOfScreen);for (EnemyPlane enemyPlane : enemyPlanes) {enemyPlane.move();}enemyPlanes.removeIf(EnemyPlane::isOutOfScreen);checkCollisions();spawnEnemyPlanes();}@Overridepublic void paintComponent(Graphics g) {super.paintComponent(g);playerPlane.draw(g);for (Bullet bullet : bullets) {bullet.draw(g);}for (EnemyPlane enemyPlane : enemyPlanes) {enemyPlane.draw(g);}}private void spawnEnemyPlanes() {// 生成敌机的逻辑}private void checkCollisions() {// 检查碰撞的逻辑}private class TAdapter extends KeyAdapter {@Overridepublic void keyReleased(KeyEvent e) {playerPlane.keyReleased(e);}@Overridepublic void keyPressed(KeyEvent e) {playerPlane.keyPressed(e);}}
}

2.3 创建游戏元素类

接下来，创建玩家飞机、敌机和子弹的类。

import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.KeyEvent;public class PlayerPlane {private int x, y;private int speed;public PlayerPlane(int x, int y) {this.x = x;this.y = y;this.speed = 5;}public void draw(Graphics g) {g.setColor(Color.BLUE);g.fillRect(x, y, 50, 20);}public void move() {// 移动逻辑}public void keyReleased(KeyEvent e) {// 键盘释放逻辑}public void keyPressed(KeyEvent e) {// 键盘按下逻辑}
}class EnemyPlane {private int x, y;private int speed;public EnemyPlane(int x, int y) {this.x = x;this.y = y;this.speed = 2;}public void draw(Graphics g) {g.setColor(Color.RED);g.fillRect(x, y, 50, 20);}public void move() {y += speed;}public boolean isOutOfScreen() {return y > 600;}
}class Bullet {private int x, y;private int speed;public Bullet(int x, int y) {this.x = x;this.y = y;this.speed = 10;}public void draw(Graphics g) {g.setColor(Color.YELLOW);g.fillRect(x, y, 5, 10);}public void move() {y -= speed;}public boolean isOutOfScreen() {return y < 0;}
}

2.4 实现游戏逻辑

在GameBoard类中实现生成敌机、检查碰撞和处理玩家输入的逻辑。

private void spawnEnemyPlanes() {// 简单的敌机生成逻辑if (enemyPlanes.size() < 5) {int x = (int) (Math.random() * 800);enemyPlanes.add(new EnemyPlane(x, 0));}
}private void checkCollisions() {// 简单的碰撞检测逻辑for (Bullet bullet : bullets) {for (EnemyPlane enemyPlane : enemyPlanes) {if (bullet.getBounds().intersects(enemyPlane.getBounds())) {bullets.remove(bullet);enemyPlanes.remove(enemyPlane);break;}}}
}private class TAdapter extends KeyAdapter {@Overridepublic void keyReleased(KeyEvent e) {playerPlane.keyReleased(e);}@Overridepublic void keyPressed(KeyEvent e) {playerPlane.keyPressed(e);if (e.getKeyCode() == KeyEvent.VK_SPACE) {bullets.add(new Bullet(playerPlane.getX() + 22, playerPlane.getY()));}}
}
