用python写一个飞机大战小游戏代码

好的，以下是一个简单的飞机大战小游戏代码，仅供参考：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口大小
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("飞机大战")

# 加载背景图片
background = pygame.image.load("images/background.png")

# 加载飞机图片
player_plane = pygame.image.load("images/player.png")
player_plane_rect = player_plane.get_rect()
player_plane_rect.midbottom = (screen_width // 2, screen_height - 20)

# 加载子弹图片
bullet = pygame.image.load("images/bullet.png")
bullet_rect = bullet.get_rect()

# 加载敌机图片
enemy_plane = pygame.image.load("images/enemy.png")
enemy_planes = []

# 初始化得分
score = 0

# 设置游戏时钟
clock = pygame.time.Clock()

# 定义函数：创建敌机
def create_enemy():
    enemy_plane_rect = enemy_plane.get_rect()
    enemy_plane_rect.left = random.randint(0, screen_width - enemy_plane_rect.width)
    enemy_plane_rect.top = -enemy_plane_rect.height
    enemy_planes.append(enemy_plane_rect)

# 定义函数：移动敌机
def move_enemy():
    for enemy_plane_rect in enemy_planes:
        enemy_plane_rect.top += 5
        if enemy_plane_rect.top > screen_height:
            enemy_planes.remove(enemy_plane_rect)

# 定义函数：检测子弹碰撞敌机
def check_bullet_hit_enemy():
    global score
    for enemy_plane_rect in enemy_planes:
        if bullet_rect.colliderect(enemy_plane_rect):
            enemy_planes.remove(enemy_plane_rect)
            score += 10

# 定义函数：检测飞机碰撞敌机
def check_plane_hit_enemy():
    for enemy_plane_rect in enemy_planes:
        if player_plane_rect.colliderect(enemy_plane_rect):
            return True
    return False

# 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_SPACE:
                bullet_rect.midbottom = player_plane_rect.midtop
                bullet_shot = True

    # 移动飞机
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player_plane_rect.move_ip(-5, 0)
    elif keys[pygame.K_RIGHT]:
        player_plane_rect.move_ip(5, 0)
    if player_plane_rect.left < 0:
        player_plane_rect.left = 0
    elif player_plane_rect.right > screen_width:
        player_plane_rect.right = screen_width

    # 移动子弹
    if bullet_rect.bottom > 0:
        bullet_rect.move_ip(0, -10)
    else:
        bullet_shot = False

    # 检测子弹碰撞敌机
    if bullet_shot:
        check_bullet_hit_enemy()

    # 创建敌机
    if random.randint(1, 50) == 1:
        create_enemy()

    # 移动敌机
    move_enemy()

    # 检测飞机碰撞敌机
    if check_plane_hit_enemy():
        running = False

    # 绘制游戏
    screen.blit(background, (0, 0))
    screen.blit(player_plane, player_plane_rect)
    if bullet_shot:
        screen.blit(bullet, bullet_rect)
    for enemy_plane_rect in enemy_planes:
        screen.blit(enemy_plane, enemy_plane_rect)
    score_font = pygame.font.Font(None, 36)
    score_text = score_font.render("得分：" + str(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
    pygame.display.update()

    # 设置游戏帧率
    clock.tick(60)

# 结束游戏
pygame.quit()

需要注意的是，此代码仅为一个简单的示例，游戏玩法和细节需要根据需求自行修改和完善。
