python游戏生成随机小球

在Python中，我们可以利用`random`模块以及`pygame`库来创建一个简单的随机移动的小球游戏。首先，你需要安装`pygame`，如果还没安装，可以使用`pip install pygame`命令。

以下是一个基础的示例，展示如何生成一个随机位置并随机移动的小球：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置窗口大小
window_size = (800, 600)
screen = pygame.display.set_mode(window_size)

# 小球属性
ball_radius = 20
ball_color = (255, 0, 0)  # 红色

# 随机生成初始位置
ball_pos = [random.randint(0, window_size[0] - ball_radius),
            random.randint(0, window_size[1] - ball_radius)]

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

    # 移动小球
    ball_pos[0] += random.uniform(-5, 5)  # 随机速度在-5到5之间
    ball_pos[1] += random.uniform(-5, 5)

    # 如果小球超出屏幕边界，让它反弹回来
    if ball_pos[0] < ball_radius or ball_pos[0] > window_size[0] - ball_radius:
        ball_pos[0] = ball_radius if ball_pos[0] < ball_radius else window_size[0] - ball_radius
    if ball_pos[1] < ball_radius or ball_pos[1] > window_size[1] - ball_radius:
        ball_pos[1] = ball_radius if ball_pos[1] < ball_radius else window_size[1] - ball_radius

    # 绘制小球
    pygame.draw.circle(screen, ball_color, ball_pos, ball_radius)

    # 更新屏幕
    pygame.display.update()

# 退出pygame
pygame.quit()
