用Python写射击小游戏的代码

好的，我可以为您提供一个简单的 Python 射击小游戏的代码。请注意，这只是一个基础的示例，您可以根据自己的需要进行修改和改进。

import pygame
import random

pygame.init()

# 设置游戏窗口的大小
screen_width = 800
screen_height = 600

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)

# 创建游戏窗口
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('射击小游戏')

# 加载图片
player_img = pygame.image.load('player.png').convert()
player_img.set_colorkey(white)
enemy_img = pygame.image.load('enemy.png').convert()
enemy_img.set_colorkey(white)

# 设置游戏时钟
clock = pygame.time.Clock()

# 定义玩家，敌人和子弹类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.transform.scale(player_img, (50, 50))
        self.rect = self.image.get_rect()
        self.rect.x = screen_width // 2
        self.rect.y = screen_height - 100
        self.speed_x = 0
        self.speed_y = 0
    
    def update(self):
        self.rect.x += self.speed_x
        self.rect.y += self.speed_y
        if self.rect.left < 0:

        if self.rect.top > screen_height + 10 or self.rect.left < -25 or self.rect.right > screen_width + 20:

            self.rect.y = random.randrange(-100, -40)

        if self.rect.bottom < 0:
            self.kill()

# 创建游戏角色和精灵组

    # 绘制游戏界面
    screen.fill(white)
    all_sprites.draw(screen)
    pygame.display.flip()

# 关闭游戏窗口
pygame.quit()
