用python写一个雷霆战机

好的，以下是一个简单的雷霆战机游戏示例，使用Pygame库编写。

import pygame
import random

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 初始化 Pygame
pygame.init()

# 设置屏幕大小
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

# 设置游戏标题
pygame.display.set_caption("雷霆战机")

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

# 定义玩家飞机类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("player.png").convert()
        self.image.set_colorkey(BLACK)
        self.rect = self.image.get_rect()
        self.rect.x = 350
        self.rect.y = 500

    def update(self):
        # 获取键盘事件
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            self.rect.x -= 5
        elif keys[pygame.K_RIGHT]:
            self.rect.x += 5
        elif keys[pygame.K_UP]:
            self.rect.y -= 5
        elif keys[pygame.K_DOWN]:
            self.rect.y += 5

        # 确保玩家飞机在屏幕范围内
        if self.rect.x < 0:
            self.rect.x = 0
        elif self.rect.x > SCREEN_WIDTH - self.rect.width:
            self.rect.x = SCREEN_WIDTH - self.rect.width
        elif self.rect.y < 0:
            self.rect.y = 0
        elif self.rect.y > SCREEN_HEIGHT - self.rect.height:
            self.rect.y = SCREEN_HEIGHT - self.rect.height

# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("enemy.png").convert()
        self.image.set_colorkey(BLACK)
        self.rect = self.image.get_rect()
        self.rect.x = random.randrange(SCREEN_WIDTH - self.rect.width)
        self.rect.y = random.randrange(-100, -40)
        self.speedy = random.randrange(1, 8)
        self.speedx = random.randrange(-3, 3)

    def update(self):
        self.rect.y += self.speedy
        self.rect.x += self.speedx

        # 敌机超过屏幕底端时重新生成
        if self.rect.top > SCREEN_HEIGHT + 10 or self.rect.left < -25 or self.rect.right > SCREEN_WIDTH + 20:
            self.rect.x = random.randrange(SCREEN_WIDTH - self.rect.width)
            self.rect.y = random.randrange(-100, -40)
            self.speedy = random.randrange(1, 8)

# 创建所有精灵组
all_sprites = pygame.sprite.Group()
enemies = pygame.sprite.Group()
bullets = pygame.sprite.Group()

# 创建玩家飞机
player = Player()
all_sprites.add(player)

# 创建敌机
for i in range(10):
    enemy = Enemy()
    all_sprites.add(enemy)
    enemies.add(enemy)

# 设置游戏循环
done = False
clock = pygame.time.Clock()
score = 0

while not done:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                # 创建子弹
                bullet = pygame.sprite.Sprite()
                bullet.image = pygame.Surface([4, 10])
                bullet.image.fill(RED)
                bullet.rect = bullet.image.get_rect()
                bullet.rect.x = player.rect.x + player.rect.width / 2
                bullet.rect.y = player.rect.y - 10
                bullets.add(bullet)
                all_sprites.add(bullet)

    # 更新所有精灵
    all_sprites.update()

    # 检测子弹是否击中敌机
    hits = pygame.sprite.groupcollide(enemies, bullets, True, True)
    for hit in hits:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
        score += 1

    # 检测敌机是否撞到玩家飞机
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        done = True

    # 绘制背景和所有精灵
    screen.blit(background_image, [0, 0])
    all_sprites.draw(screen)

    # 绘制得分
    font = pygame.font.Font(None, 36)
    text = font.render("Score: " + str(score), True, WHITE)
    screen.blit(text, [10, 10])

    # 更新屏幕
    pygame.display.flip()

    # 控制游戏速度
    clock.tick(60)

# 退出 Pygame
pygame.quit()

该游戏使用箭头键控制玩家飞机移动，空格键发射子弹，玩家需要躲避敌机并尽可能地击落敌机，得分越高越好。
