用python代码做一个打球球小游戏

好的，以下是用 Python 语言实现的打球球小游戏示例代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

# 创建游戏窗口
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("打球球小游戏")

# 设置游戏帧率
clock = pygame.time.Clock()

# 球的大小和速度
BALL_RADIUS = 20
BALL_SPEED = 5

# 球的初始位置和速度
ball_x = random.randint(BALL_RADIUS, WINDOW_WIDTH - BALL_RADIUS)
ball_y = random.randint(BALL_RADIUS, WINDOW_HEIGHT - BALL_RADIUS)
ball_speed_x = BALL_SPEED
ball_speed_y = BALL_SPEED

# 玩家的位置和大小
player_width = 100
player_height = 20
player_x = (WINDOW_WIDTH - player_width) // 2
player_y = WINDOW_HEIGHT - player_height

# 游戏分数
score = 0

# 游戏结束标志
game_over = False

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

# 游戏循环
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player_x -= 10
            elif event.key == pygame.K_RIGHT:
                player_x += 10

    # 移动球
    ball_x += ball_speed_x
    ball_y += ball_speed_y

    # 球碰到左右边界反弹
    if ball_x - BALL_RADIUS < 0 or ball_x + BALL_RADIUS > WINDOW_WIDTH:
        ball_speed_x = -ball_speed_x

    # 球碰到顶部反弹
    if ball_y - BALL_RADIUS < 0:
        ball_speed_y = -ball_speed_y

    # 球碰到玩家反弹
    if ball_y + BALL_RADIUS >= player_y and \
            ball_x >= player_x and \
            ball_x <= player_x + player_width:
        ball_speed_y = -ball_speed_y
        score += 10

    # 球落下游戏结束
    if ball_y + BALL_RADIUS > WINDOW_HEIGHT:
        game_over = True

    # 绘制游戏界面
    screen.fill((255, 255, 255))
    pygame.draw.circle(screen, (255, 0, 0), (ball_x, ball_y), BALL_RADIUS)
    pygame.draw.rect(screen, (0, 0, 255), (player_x, player_y, player_width, player_height))
    score_text = font.render("Score: " + str(score), True, (0, 0, 0))
    screen.blit(score_text, (10, 10))
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(60)

# 游戏结束，退出 Pygame
pygame.quit()

你可以将这段代码保存到一个 Python 文件中并运行，就可以玩到这个打球球小游戏了。
