怎么用python写飞机大战

以下是一个简单的Python飞机大战游戏的示例代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 480
screen_height = 640
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
background = pygame.image.load("background.png")

# 加载玩家飞机图
player_img = pygame.image.load("player.png")
player_width, player_height = player_img.get_rect().size
player_x = (screen_width - player_width) // 2
player_y = screen_height - player_height - 50

# 加载敌机图
enemy_img = pygame.image.load("enemy.png")
enemy_width, enemy_height = enemy_img.get_rect().size

# 定义敌机列表
enemies = []
for i in range(5):
    enemy_x = random.randint(0, screen_width - enemy_width)
    enemy_y = random.randint(-500, -enemy_height)
    enemies.append([enemy_x, enemy_y])

# 设置玩家飞机移动速度
player_speed = 5

# 设置敌机移动速度
enemy_speed = 3

# 设置游戏帧率
clock = pygame.time.Clock()
fps = 60

# 游戏主循环
running = True
while running:
    # 事件处理
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 玩家飞机移动
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and player_x > 0:
        player_x -= player_speed
    if keys[pygame.K_RIGHT] and player_x < screen_width - player_width:
        player_x += player_speed
    if keys[pygame.K_UP] and player_y > 0:
        player_y -= player_speed
    if keys[pygame.K_DOWN] and player_y < screen_height - player_height:
        player_y += player_speed

    # 敌机移动
    for enemy in enemies:
        enemy[1] += enemy_speed
        if enemy[1] > screen_height:
            enemy[0] = random.randint(0, screen_width - enemy_width)
            enemy[1] = random.randint(-500, -enemy_height)

    # 碰撞检测
    for enemy in enemies:
        if (player_x + player_width > enemy[0] and player_x < enemy[0] + enemy_width
                and player_y + player_height > enemy[1] and player_y < enemy[1] + enemy_height):
            running = False

    # 绘制游戏元素
    screen.blit(background, (0, 0))
    screen.blit(player_img, (player_x, player_y))
    for enemy in enemies:
        screen.blit(enemy_img, (enemy[0], enemy[1]))
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(fps)

# 退出 Pygame
pygame.quit()

运行以上代码，可以看到一个简单的飞机大战游戏。在这个游戏中，玩家飞机可以通过键盘上下左右键进行移动，敌机会从屏幕顶部不断向下移动，玩家飞机与敌机碰撞时游戏结束。
