用pygame写一个很小众的游戏

以下是一个小众的pygame游戏示例：

游戏名称：躲避弹球

游戏规则：玩家需要控制一个小球躲避弹球，直到获得一定数量的分数或者被弹球命中。

游戏操作：玩家可以使用键盘上的左右箭头键来控制小球的移动。

游戏界面：游戏界面包括一个黑色背景和一个白色小球，弹球从上方不断下落，玩家需要躲避弹球并尽可能多地接触到白色小球，以获得分数。

游戏实现：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 500
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("躲避弹球")

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 定义字体
font = pygame.font.Font(None, 36)

# 初始化游戏数据
score = 0
game_over = False

# 定义球的大小和速度
ball_radius = 10
ball_speed = 5

# 定义弹球的初始位置和速度
ball_x = random.randint(ball_radius, screen_width - ball_radius)
ball_y = 0
ball_dx = random.randint(-ball_speed, ball_speed)
ball_dy = ball_speed

# 定义小球的初始位置和速度
player_x = screen_width // 2
player_y = screen_height - 50
player_dx = ball_speed

# 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

    # 更新游戏数据
    ball_x += ball_dx
    ball_y += ball_dy
    if ball_x < ball_radius or ball_x > screen_width - ball_radius:
        ball_dx = -ball_dx
    if ball_y < ball_radius:
        ball_dy = ball_speed
    elif ball_y > player_y - ball_radius and ball_x > player_x - ball_radius and ball_x < player_x + ball_radius:
        ball_dy = -ball_dy
        score += 1
    elif ball_y > screen_height - ball_radius:
        game_over = True

    player_x += player_dx
    if player_x < ball_radius or player_x > screen_width - ball_radius:
        player_dx = -player_dx

    # 绘制游戏界面
    screen.fill(BLACK)
    pygame.draw.circle(screen, WHITE, (player_x, player_y), ball_radius)
    pygame.draw.circle(screen, RED, (ball_x, ball_y), ball_radius)
    score_text = font.render("Score: {}".format(score), True, WHITE)
    screen.blit(score_text, (10, 10))

    # 更新屏幕
    pygame.display.update()

# 显示游戏结束信息
game_over_text = font.render("Game Over", True, WHITE)
screen.blit(game_over_text, (screen_width // 2 - 80, screen_height // 2 - 20))
pygame.display.update()

# 等待用户关闭游戏窗口
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
