用python使用pygame写弹珠的小游戏

当然可以！以下是一个简单的弹珠游戏实现代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

WIDTH = 480
HEIGHT = 600
FPS = 60

# 设置屏幕大小
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("弹珠小游戏")

# 设置时钟对象，控制游戏帧率
clock = pygame.time.Clock()

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

# 定义球、挡板的属性
BALL_RADIUS = 10
BALL_COLOR = RED
BALL_SPEED = 5

PAD_WIDTH = 80
PAD_HEIGHT = 10
PAD_COLOR = GREEN
PAD_SPEED = 5

# 创建球、挡板对象
ball_pos = [WIDTH/2, HEIGHT/2]
ball_vel = [random.randint(-BALL_SPEED, BALL_SPEED), random.randint(-BALL_SPEED, BALL_SPEED)]

pad_pos = [WIDTH/2 - PAD_WIDTH/2, HEIGHT - PAD_HEIGHT - 10]
pad_vel = [0, 0]

# 定义绘制球的函数
def draw_ball(ball_pos):
    pygame.draw.circle(screen, BALL_COLOR, ball_pos, BALL_RADIUS)

# 定义绘制挡板的函数
def draw_pad(pad_pos):
    pygame.draw.rect(screen, PAD_COLOR, (pad_pos[0], pad_pos[1], PAD_WIDTH, PAD_HEIGHT))

# 游戏循环
running = True
while running:
    # 控制游戏帧率
    clock.tick(FPS)
    
    # 处理事件队列
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                pad_vel[0] = -PAD_SPEED
            elif event.key == pygame.K_RIGHT:
                pad_vel[0] = PAD_SPEED
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT and pad_vel[0] == -PAD_SPEED:
                pad_vel[0] = 0
            elif event.key == pygame.K_RIGHT and pad_vel[0] == PAD_SPEED:
                pad_vel[0] = 0
                
    # 更新球的位置
    ball_pos[0] += ball_vel[0]
    ball_pos[1] += ball_vel[1]
    
    # 碰到边界反弹
    if ball_pos[0] < BALL_RADIUS or ball_pos[0] > WIDTH - BALL_RADIUS:
        ball_vel[0] = -ball_vel[0]
    if ball_pos[1] < BALL_RADIUS:
        ball_vel[1] = -ball_vel[1]
    if ball_pos[1] > HEIGHT - BALL_RADIUS:
        running = False
    
    # 更新挡板的位置
    pad_pos[0] += pad_vel[0]
    
    # 碰到边界停止
    if pad_pos[0] < 0:
        pad_pos[0] = 0
    if pad_pos[0] > WIDTH - PAD_WIDTH:
        pad_pos[0] = WIDTH - PAD_WIDTH
        
    # 碰到挡板反弹
    if ball_pos[1] > HEIGHT - BALL_RADIUS - PAD_HEIGHT and ball_pos[0] >= pad_pos[0] and ball_pos[0] <= pad_pos[0] + PAD_WIDTH:
        ball_vel[1] = -ball_vel[1]
        
    # 清屏
    screen.fill(BLACK)
    
    # 绘制球、挡板
    draw_ball(ball_pos)
    draw_pad(pad_pos)
    
    # 更新屏幕
    pygame.display.update()

# 退出 Pygame
pygame.quit()

运行代码后，你就可以玩到一个简单的弹珠小游戏啦！
