弹球游戏代码

以下是一个简单的Python弹球游戏的代码示例，仅供参考：

import pygame
from pygame.locals import *
import random

# 初始化Pygame
pygame.init()

# 定义游戏窗口大小
WINDOW_WIDTH = 640
WINDOW_HEIGHT = 480

# 定义弹珠和挡板的大小和颜色
BALL_RADIUS = 10
BALL_COLOR = (255, 255, 255)
PADDLE_WIDTH = 80
PADDLE_HEIGHT = 10
PADDLE_COLOR = (255, 255, 255)

# 定义砖块的大小和颜色
BRICK_WIDTH = 60
BRICK_HEIGHT = 20
BRICK_COLOR = (255, 255, 255)

# 定义游戏背景颜色
BG_COLOR = (0, 0, 0)

# 设置游戏窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('弹珠小游戏')

# 定义全局变量
score = 0
lives = 3

# 定义弹珠和挡板的初始位置和速度
ball_x = WINDOW_WIDTH // 2
ball_y = WINDOW_HEIGHT // 2
ball_dx = 5
ball_dy = 5
paddle_x = (WINDOW_WIDTH - PADDLE_WIDTH) // 2
paddle_y = WINDOW_HEIGHT - PADDLE_HEIGHT

# 定义砖块的位置和数量
brick_rows = 5
brick_cols = 8
bricks = []
for row in range(brick_rows):
    brick_row = []
    for col in range(brick_cols):
        brick_row.append(1)
    bricks.append(brick_row)

# 定义字体
font = pygame.font.SysFont('Arial', 16)

# 定义游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEMOTION:
            paddle_x = event.pos[0]

    # 绘制游戏界面
    window.fill(BG_COLOR)
    pygame.draw.circle(window, BALL_COLOR, (ball_x, ball_y), BALL_RADIUS)
    pygame.draw.rect(window, PADDLE_COLOR, (paddle_x, paddle_y, PADDLE_WIDTH, PADDLE_HEIGHT))
    for row in range(brick_rows):
        for col in range(brick_cols):
            if bricks[row][col] == 1:
                brick_x = col * BRICK_WIDTH
                brick_y = row * BRICK_HEIGHT
                pygame.draw.rect(window, BRICK_COLOR, (brick_x, brick_y, BRICK_WIDTH, BRICK_HEIGHT))

    # 更新弹珠位置
    ball_x += ball_dx
    ball_y += ball_dy

    # 碰撞检测
    if ball_x <= BALL_RADIUS or ball_x >= WINDOW_WIDTH - BALL_RADIUS:
        ball_dx = -ball_dx
    if ball_y <= BALL_RADIUS:
        ball_dy = -ball_dy
    elif ball_y >= WINDOW_HEIGHT - BALL_RADIUS - PADDLE_HEIGHT:
        if ball_x >= paddle_x and ball_x <= paddle_x + PADDLE_WIDTH:
            ball_dy = -ball_dy
            score += 10
        else:
            lives -= 1
            if lives == 0:
                pygame.quit()
                sys.exit()
            ball_x = WINDOW_WIDTH // 2
            ball_y = WINDOW_HEIGHT // 2
            ball_dx = random.choice([-5, 5])
            ball_dy = 5

    # 砖块碰撞检测
    row = ball_y // BRICK_HEIGHT
    col = ball_x // BRICK_WIDTH
    if row < brick_rows and col < brick_cols and bricks[row][col] == 1:
        bricks[row][col] = 0
        ball_dy = -ball_dy
        score += 50

    # 显示得分和生命值
    score_text = font.render('得分：' + str(score), True, (255, 255, 255))
    lives_text = font.render('生命：' + str(lives), True, (255, 255, 255))
    window.blit(score_text, (10, 10))
    window.blit(lives_text, (WINDOW_WIDTH - lives_text.get_width() - 10, 10))

    # 更新窗口
    pygame.display.update()

    # 控制游戏帧率
    pygame.time.Clock().tick(60)

以上是一个简单的Python弹球游戏的代码示例，仅供参考。实际开发中，还需进一步完善和优化代码。
