python 飞机大战游戏

好的，以下是一个简单的 Python 飞机大战游戏示例代码：

import pygame
import sys
import random

# 初始化pygame
pygame.init()

# 设置屏幕大小和标题
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('飞机大战')

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

# 加载飞机图片和位置
player_img = pygame.image.load('images/player.png').convert_alpha()
player_rect = player_img.get_rect()
player_rect.left = (screen_width - player_rect.width) // 2
player_rect.top = screen_height - player_rect.height - 50

# 加载敌机图片和位置
enemy_img = pygame.image.load('images/enemy.png').convert_alpha()
enemy_rect = enemy_img.get_rect()
enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
enemy_rect.top = -enemy_rect.height
enemy_speed = 1

# 加载子弹图片和位置
bullet_img = pygame.image.load('images/bullet.png').convert_alpha()
bullet_rect = bullet_img.get_rect()
bullet_speed = 5
bullet_list = []

# 加载字体
font = pygame.font.Font(None, 36)

# 设置计分和生命值
score = 0
life = 3

# 游戏主循环
while True:
    # 处理游戏退出事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # 处理键盘事件
    key_pressed = pygame.key.get_pressed()
    if key_pressed[pygame.K_LEFT]:
        player_rect.left -= 5
    elif key_pressed[pygame.K_RIGHT]:
        player_rect.left += 5
    elif key_pressed[pygame.K_SPACE]:
        bullet_list.append([player_rect.left + player_rect.width // 2 - bullet_rect.width // 2, player_rect.top - bullet_rect.height])

    # 移动敌机和子弹
    enemy_rect.top += enemy_speed
    for b in bullet_list:
        b[1] -= bullet_speed

    # 检测敌机和子弹是否碰撞
    for b in bullet_list:
        if enemy_rect.colliderect(pygame.Rect(b[0], b[1], bullet_rect.width, bullet_rect.height)):
            bullet_list.remove(b)
            enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
            enemy_rect.top = -enemy_rect.height
            enemy_speed += 0.1
            score += 10

    # 检测敌机是否碰撞到玩家
    if enemy_rect.colliderect(player_rect):
        life -= 1
        enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
        enemy_rect.top = -enemy_rect.height
        enemy_speed = 1

    # 绘制背景、玩家、敌机、子弹、分数和生命值
    screen.blit(bg_img, (0, 0))
    screen.blit(player_img, player_rect)
    screen.blit(enemy_img, enemy_rect)
    for b in bullet_list:
        screen.blit(bullet_img, (b[0], b[1]))
    score_text = font.render('Score: ' + str(score), True, (255, 255, 255))
    life_text = font.render('Life: ' + str(life), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
    screen.blit(life_text, (screen_width - life_text.get_width() - 10, 10))

    # 更新屏幕
    pygame.display.update()

    # 检测生命值是否为0，如果是则结束游戏
    if life == 0:
        gameover_text = font.render('Game Over', True, (255, 0, 0))
        screen.blit(gameover_text, ((screen_width - gameover_text.get_width()) // 2, (screen_height - gameover_text.get_height()) // 2))
        pygame.display.update()
        pygame.time.delay(3000)
        pygame.quit()
        sys.exit()

在运行之前，需要先准备好游戏所需的图片资源，并将其放在与代码同级的 images 文件夹中。此外，还需要安装 Pygame 库。
