Building a Simple Airplane Shooting Game with Pygame (Python)

Remember the classic WeChat "Airplane Battle" game? This article shows how to recreate a similar 2D shooter using Python's Pygame library, providing a complete, though simple, version of the game.

1. Environment Installation

Prepare Python 3, PyCharm, and install the Pygame module.

pip install -i https://pypi.douban.com/simple/ pygame<br/>

2. Player Plane

def main():<br/>    global is_hit<br/>    global nums<br/>    screen = pygame.display.set_mode((480, 852), 0, 32)<br/>    background = pygame.image.load("./feiji/background.png")<br/>    # 创建飞机<br/>    hero = HeroPlane(screen)<br/>    enermy_plane = EnermyPlane(screen)<br/>    while True:<br/>        global hero_nums<br/>        global enermy_nums<br/>        # 显示背景<br/>        screen.blit(background, (0, 0))<br/>        # 显示我方飞机<br/>        hero.display()<br/>        # 测试是否被子弹击中<br/>        hero.test(enermy_plane.bullets)<br/>        if hero.is_hit:<br/>            hero_nums += 1<br/>        if hero_nums == 10:<br/>            hero.image = pygame.image.load("./feiji/hero_blowup_n1.png")<br/>        elif hero_nums == 20:<br/>            hero.image = pygame.image.load("./feiji/hero_blowup_n2.png")<br/>        elif hero_nums == 30:<br/>            hero.image = pygame.image.load("./feiji/hero_blowup_n3.png")<br/>        elif hero_nums == 40:<br/>            hero.image = pygame.image.load("./feiji/hero_blowup_n4.png")<br/>        elif hero_nums > 50:<br/>            break<br/>

3. Enemy Plane

# 显示敌飞机<br/>enermy_plane.display()<br/>enermy_plane.test(hero.bullets)<br/>if enermy_plane.is_hit:<br/>    enermy_nums += 1<br/>if enermy_nums == 10:<br/>    enermy_plane.image = pygame.image.load("./feiji/enemy0_down1.png")<br/>elif enermy_nums == 20:<br/>    enermy_plane.image = pygame.image.load("./feiji/enemy0_down2.png")<br/>elif enermy_nums == 30:<br/>    enermy_plane.image = pygame.image.load("./feiji/enemy0_down3.png")<br/>elif enermy_nums == 40:<br/>    enermy_plane.image = pygame.image.load("./feiji/enemy0_down4.png")<br/>elif enermy_nums > 50:<br/>    enermy_plane = EnermyPlane(screen)<br/>    enermy_nums = 0<br/>else:<br/>    enermy_plane.move()<br/>    enermy_plane.fire()<br/># 控制飞机左右<br/>key_control(hero)<br/># 刷新屏幕<br/>pygame.display.update()<br/># 程序休眠0.01秒<br/>time.sleep(0.01)<br/>

4. Keyboard Control

def key_control(hero):<br/>    for event in pygame.event.get():<br/>        if event.type == QUIT:<br/>            print("exit")<br/>            exit()<br/>        elif event.type == KEYDOWN:<br/>            if event.key == K_a or event.key == K_LEFT:<br/>                hero.move_left()<br/>                print("left")<br/>            elif event.key == K_d or event.key == K_RIGHT:<br/>                hero.move_right()<br/>                print("right")<br/>            elif event.key == K_SPACE:<br/>                hero.fire()<br/>                print("space")<br/>

5. Bullet Collision Detection

class BasePlane(object):<br/>    def __init__(self, screen, x, y, image):<br/>        self.x = x<br/>        self.y = y<br/>        self.screen = screen<br/>        self.image = pygame.image.load(image)<br/>        self.is_hit = False  # 此标志用来表示飞机是否被击中了<br/>        self.bullets = []<br/><br/>    def test(self, bullets):<br/>        for bullet in bullets:<br/>            if self.x < bullet.x < self.x + self.image.get_width() and \
                self.y < bullet.y < self.y + self.image.get_height():<br/>                self.is_hit = True<br/>        # 检测子弹碰撞<br/>        for item in self.bullets:<br/>            for bullet in bullets:<br/>                if item.x < bullet.x < item.x + item.image.get_width() and \
                    item.y < bullet.y < item.y + item.image.get_height():<br/>                    item.is_hit = True<br/>                    bullet.is_hit = True<br/>

6. Visual Results

Conclusion

The simple version runs infinitely without power‑ups or varied aircraft, but it demonstrates the core mechanics of a 2D shooter; further enhancements can be added later.
