用Python语言写一款游戏

很高兴参与这个任务！以下是一个简单的Python游戏示例，名为“飞行射击游戏”：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 640
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 加载背景图像
background_image = pygame.image.load("background.jpg").convert()

# 加载玩家图像
player_image = pygame.image.load("player.png").convert()
player_image.set_colorkey((255, 255, 255))

# 加载敌人图像
enemy_image = pygame.image.load("enemy.png").convert()
enemy_image.set_colorkey((255, 255, 255))

# 加载子弹图像
bullet_image = pygame.image.load("bullet.png").convert()
bullet_image.set_colorkey((255, 255, 255))

# 定义玩家类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = player_image
        self.rect = self.image.get_rect()
        self.rect.x = screen_width // 2
        self.rect.y = screen_height - self.rect.height
        self.speed_x = 0
    
    def update(self):
        self.rect.x += self.speed_x
        if self.rect.x < 0:
            self.rect.x = 0
        if self.rect.x > screen_width - self.rect.width:
            self.rect.x = screen_width - self.rect.width

# 定义敌人类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = enemy_image
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - self.rect.width)
        self.rect.y = -self.rect.height
        self.speed_y = random.randint(1, 3)
    
    def update(self):
        self.rect.y += self.speed_y
        if self.rect.y > screen_height:
            self.kill()

# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = bullet_image
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.speed_y = -5
    
    def update(self):
        self.rect.y += self.speed_y
        if self.rect.y < -self.rect.height:
            self.kill()

# 创建玩家对象
player = Player()
all_sprites = pygame.sprite.Group()
all_sprites.add(player)

# 创建敌人组
enemies = pygame.sprite.Group()

# 创建子弹组
bullets = pygame.sprite.Group()

# 设置游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player.speed_x = -5
            elif event.key == pygame.K_RIGHT:
                player.speed_x = 5
            elif event.key == pygame.K_SPACE:
                bullet = Bullet(player.rect.centerx, player.rect.top)
                all_sprites.add(bullet)
                bullets.add(bullet)
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT and player.speed_x < 0:
                player.speed_x = 0
            elif event.key == pygame.K_RIGHT and player.speed_x > 0:
                player.speed_x = 0
    
    # 更新游戏状态
    all_sprites.update()
    
    # 检测碰撞
    hits = pygame.sprite.groupcollide(enemies, bullets, True, True)
    for hit in hits:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        running = False
    
    # 生成敌人
    if random.randint(1, 60) == 1:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    # 绘制游戏界面
    screen.blit(background_image, (0, 0))
    all_sprites.draw(screen)
    pygame.display.flip()

# 退出Pygame
pygame.quit()

这个游戏的规则非常简单：玩家控制一个飞机，在屏幕上移动并发射子弹，消灭从顶部飞来的敌人。如果有敌人飞到底部，游戏结束。通过不断消灭敌人，玩家可以得到更高的分数。这个游戏还有很多可以改进的地方，比如增加多种敌人、子弹和道具，加入声音和音效等等
