用pygame做一个战争游戏

好的，下面是一个简单的战争游戏的代码示例，使用了Pygame库：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置游戏屏幕大小和标题
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("战争游戏")

# 设置游戏时钟
clock = pygame.time.Clock()

# 加载游戏资源
background_image = pygame.image.load("background.png")
player_image = pygame.image.load("player.png")
enemy_image = pygame.image.load("enemy.png")
bullet_image = pygame.image.load("bullet.png")

# 定义游戏对象类
class GameObject:
    def __init__(self, x, y, image):
        self.x = x
        self.y = y
        self.image = image
        self.width = image.get_width()
        self.height = image.get_height()
    
    def draw(self, screen):
        screen.blit(self.image, (self.x, self.y))
    
    def collide(self, other):
        return (self.x < other.x + other.width and
                self.x + self.width > other.x and
                self.y < other.y + other.height and
                self.y + self.height > other.y)

# 定义玩家类
class Player(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = 5
        self.bullets = []
    
    def shoot(self):
        bullet = Bullet(self.x + self.width/2 - bullet_image.get_width()/2, self.y, bullet_image)
        self.bullets.append(bullet)
    
    def update(self):
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            self.x -= self.speed
        elif keys[pygame.K_RIGHT]:
            self.x += self.speed
        if keys[pygame.K_SPACE]:
            self.shoot()
        for bullet in self.bullets:
            bullet.update()
            if bullet.y < -bullet.height:
                self.bullets.remove(bullet)
    
    def collide(self, other):
        for bullet in self.bullets:
            if bullet.collide(other):
                self.bullets.remove(bullet)
                return True
        return super().collide(other)

# 定义敌人类
class Enemy(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = 3
    
    def update(self):
        self.y += self.speed

# 定义子弹类
class Bullet(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = 10
    
    def update(self):
        self.y -= self.speed
    
    def collide(self, other):
        return super().collide(other)

# 创建游戏对象
player = Player(screen_width/2 - player_image.get_width()/2, screen_height - player_image.get_height() - 20, player_image)
enemies = []
bullets = []
for i in range(10):
    enemy = Enemy(random.randint(0, screen_width - enemy_image.get_width()), -random.randint(0, screen_height), enemy_image)
    enemies.append(enemy)

# 游戏循环
running = True
while running:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    # 更新游戏对象
    player.update()
    for enemy in enemies:
        enemy.update()
        if enemy.y > screen_height:
            enemies.remove(enemy)
    for bullet in player.bullets:
        for enemy in enemies:
            if bullet.collide(enemy):
                enemies.remove(enemy)
        if bullet.y < -bullet.height:
            player.bullets.remove(bullet)
    
    # 检测碰撞
    for enemy in enemies:
        if player.collide(enemy):
            running = False
    
    # 绘制游戏界面
    screen.blit(background_image, (0, 0))
    player.draw(screen)
    for enemy in enemies:
        enemy.draw(screen)
    for bullet in player.bullets:
        bullet.draw(screen)
    pygame.display.update()
    
    # 控制游戏帧率
    clock.tick(60)

# 退出游戏
pygame.quit()

请注意，这只是一个简单的战争游戏示例，您可以根据自己的需求和想法进行修改和扩展。同时，您还需要自己准备游戏资源，如背景、玩家、敌人和子弹的图片等。
