pygame小游戏代码

以下是一个用Pygame编写的简单的打砖块游戏的代码示例：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置游戏界面大小
screen_width = 640
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("打砖块游戏")

# 定义颜色变量
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
blue = (0, 0, 255)

# 定义小球变量
ball_size = 10
ball_speed = [5, 5]
ball_pos = [screen_width // 2, screen_height // 2]

# 定义挡板变量
paddle_width = 75
paddle_height = 15
paddle_speed = 0
paddle_pos = [(screen_width - paddle_width) // 2, screen_height - paddle_height - 10]

# 定义砖块变量
brick_width = 60
brick_height = 15
brick_gap = 5
brick_colors = [red, blue]
brick_rows = 5
brick_cols = 8
bricks = []

# 创建砖块
for row in range(brick_rows):
    row_bricks = []
    for col in range(brick_cols):
        brick_x = col * (brick_width + brick_gap)
        brick_y = row * (brick_height + brick_gap)
        brick_color = brick_colors[row // (brick_rows // 2)]
        row_bricks.append(pygame.Rect(brick_x, brick_y, brick_width, brick_height))
    bricks.append(row_bricks)

# 定义游戏结束标志
game_over = False

# 游戏循环
while not game_over:
    # 处理游戏事件
    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:
                paddle_speed = -5
            elif event.key == pygame.K_RIGHT:
                paddle_speed = 5
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                paddle_speed = 0

    # 移动挡板
    paddle_pos[0] += paddle_speed
    if paddle_pos[0] < 0:
        paddle_pos[0] = 0
    elif paddle_pos[0] > screen_width - paddle_width:
        paddle_pos[0] = screen_width - paddle_width

    # 移动小球
    ball_pos[0] += ball_speed[0]
    ball_pos[1] += ball_speed[1]
    if ball_pos[0] < ball_size or ball_pos[0] > screen_width - ball_size:
        ball_speed[0] = -ball_speed[0]
    if ball_pos[1] < ball_size:
        ball_speed[1] = -ball_speed[1]
    elif ball_pos[1] > screen_height - ball_size:
        game_over = True

    # 检测小球是否碰到挡板
    if ball_pos[1] > screen_height - ball_size - paddle_height and \
            paddle_pos[0] <= ball_pos[0] <= paddle_pos[0] + paddle_width:
        ball_speed[1] = -ball_speed[1]

    # 检测小球是否碰到砖块
    for row in range(brick_rows):
        for col in range(brick_cols):
            brick_rect = bricks[row][col]
            if ball_pos[1] - ball_size < brick_rect.bottom and \
                    ball_pos[1] + ball_size > brick_rect.top and \
                    ball_pos[0] + ball_size > brick_rect.left and \
                    ball_pos[0] - ball_size < brick_rect.right:
                ball_speed[1] = -ball_speed[1]
                bricks[row][col] = None

    # 绘制游戏界面
    screen.fill(black)
    pygame.draw.circle(screen, white, ball_pos, ball_size)
    pygame.draw.rect(screen, white, (paddle_pos[0], paddle_pos[1], paddle_width, paddle_height))
    for row in range(brick_rows):
        for col in range(brick_cols):
            if bricks[row][col]:
                pygame.draw.rect(screen, brick_colors[row // (brick_rows // 2)], bricks[row][col])
    pygame.display.update()

# 退出Pygame
pygame.quit()

运行代码后，可以控制挡板左右移动并击打小球，尝试打掉所有砖块即可获胜。
