用python射击小游戏的代码

以下是一个简单的用 Python 编写的射击小游戏的代码示例：

import pygame
import random

# 初始化 Pygame 库
pygame.init()

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

# 设置游戏标题
pygame.display.set_caption('射击小游戏')

# 加载游戏背景音乐
pygame.mixer.music.load('background_music.mp3')
pygame.mixer.music.play(-1)

# 加载游戏背景图像
background_image = pygame.image.load('background_image.jpg').convert()

# 加载玩家飞船图像和初始位置
player_image = pygame.image.load('player_ship.png').convert_alpha()
player_rect = player_image.get_rect()
player_rect.centerx = width // 2
player_rect.bottom = height - 10

# 加载子弹图像和速度
bullet_image = pygame.image.load('bullet.png').convert_alpha()
bullet_speed = 5

# 加载敌人飞船图像和初始位置
enemy_image = pygame.image.load('enemy_ship.png').convert_alpha()
enemy_rect = enemy_image.get_rect()
enemy_rect.centerx = random.randint(0, width)
enemy_rect.top = -enemy_rect.height
enemy_speed = 3

# 加载爆炸图像和音效
explosion_image = pygame.image.load('explosion.png').convert_alpha()
explosion_sound = pygame.mixer.Sound('explosion_sound.wav')

# 设置游戏时钟
clock = pygame.time.Clock()

# 初始化游戏结束标志
game_over = False

# 游戏循环
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                # 发射子弹
                bullet_rect = bullet_image.get_rect()
                bullet_rect.centerx = player_rect.centerx
                bullet_rect.bottom = player_rect.top
                bullets.append(bullet_rect)
    
    # 移动玩家飞船
    keys_pressed = pygame.key.get_pressed()
    if keys_pressed[pygame.K_LEFT]:
        player_rect.centerx -= 5
    elif keys_pressed[pygame.K_RIGHT]:
        player_rect.centerx += 5
    
    # 移动子弹
    for bullet_rect in bullets:
        bullet_rect.top -= bullet_speed
        if bullet_rect.top < 0:
            bullets.remove(bullet_rect)
    
    # 移动敌人飞船
    enemy_rect.top += enemy_speed
    if enemy_rect.top > height:
        enemy_rect.centerx = random.randint(0, width)
        enemy_rect.top = -enemy_rect.height
    
    # 检测碰撞
    for bullet_rect in bullets:
        if bullet_rect.colliderect(enemy_rect):
            bullets.remove(bullet_rect)
            enemy_rect.centerx = random.randint(0, width)
            enemy_rect.top = -enemy_rect.height
            explosion_sound.play()
            screen.blit(explosion_image, enemy_rect)
            pygame.display.update()
    
    if player_rect.colliderect(enemy_rect):
        game_over = True
    
    # 绘制游戏界面
    screen.blit(background_image, (0, 0))
    screen.blit(player_image, player_rect)
    screen.blit(enemy_image, enemy_rect)
    for bullet_rect in bullets:
        screen.blit(bullet_image, bullet_rect)
    pygame.display.update()
    
    # 控制帧率
    clock.tick(60)

# 退出游戏
pygame.quit()
