### Python 快速编程入门 第2版 黑马程序员 飞机大战 完整代码 #### 游戏结构概述 游戏由多个模块组成，主要包括 `game.py`、`game_items.py`、`game_hub.py` 和 `game_music.py` 文件。这些文件共同协作实现了完整的飞机大战游戏逻辑。 #### 主要模块解析 ##### game.py 类定义 此文件负责初始化游戏窗口并控制整个游戏流程： ```python import pygame from game_items import * from random import * SCREEN_RECT = pygame.Rect(0, 0, 480, 700) class GameSprite(pygame.sprite.Sprite): def __init__(self, image_name, speed=1): super().__init__() self.image = pygame.image.load(image_name) self.rect = self.image.get_rect() self.speed = speed def update(self): self.rect.y += self.speed ``` ##### game_items.py 组件实现 该文件包含了游戏中各类角色的具体属性和行为方法： ```python class Background(GameSprite): def __init__(self,is_alt=False): super().__init__("./images/background.png") if is_alt: self.rect.y = -self.rect.height def update(self): super().update() if self.rect.y >= SCREEN_RECT.height: self.rect.y = -self.rect.height class Enemy(GameSprite): def __init__(self): super().__init__("./images/enemy1.png") self.speed = randint(1, 3) self.rect.bottom = 0 max_x = SCREEN_RECT.width - self.rect.width self.rect.x = randint(0, max_x) class Hero(GameSprite): def __init__(self): super().__init__("./images/me1.png", 0) self.rect.centerx = SCREEN_RECT.centerx self.rect.bottom = SCREEN_RECT.bottom - 120 self.bullets = pygame.sprite.Group() def fire(self): bullet = Bullet() bullet.rect.bottom = self.rect.y - 20 bullet.rect.centerx = self.rect.centerx self.bullets.add(bullet) class Bullet(GameSprite): def __init__(self): super().__init__("./images/bullet1.png", -2) def update(self): super().update() if self.rect.bottom < 0: self.kill() ``` ##### game_hub.py 控制中心 用于处理事件监听以及碰撞检测等功能： ```python def check_collide(hero, enemies_group, bullets_group): # 敌机撞毁英雄 enemy_list = pygame.sprite.spritecollide(hero, enemies_group, True) if len(enemy_list) > 0: hero.kill() return False else: return True def main(): screen = pygame.display.set_mode((480, 700)) clock = pygame.time.Clock() bg1 = Background() bg2 = Background(True) back_group = pygame.sprite.Group(bg1, bg2) enemy_group = pygame.sprite.Group() hero = Hero() hero_group = pygame.sprite.Group(hero) ENEMY_EVENT = pygame.USEREVENT pygame.time.set_timer(ENEMY_EVENT, 1000) while True: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() exit() elif event.type == ENEMY_EVENT: enemy = Enemy() enemy_group.add(enemy) keys_pressed = pygame.key.get_pressed() if keys_pressed[pygame.K_RIGHT]: hero.speed = 5 elif keys_pressed[pygame.K_LEFT]: hero.speed = -5 else: hero.speed = 0 hero.update() back_group.update() back_group.draw(screen) enemy_group.update() enemy_group.draw(screen) hero_group.update() hero_group.draw(screen) hero.bullets.update() hero.bullets.draw(screen) collide_result = check_collide(hero, enemy_group, hero.bullets) if not collide_result: break pygame.display.flip() clock.tick(60) if __name__ == '__main__': main() ``` ##### game_music.py 声音效果配置 这部分涉及背景音乐加载与播放功能，在实际项目中通常会单独封装成一个类来管理音频资源[^4]。
