使用Python语言实现自动随机生成一个迷宫，并能用键盘控制小球完成走迷宫游戏

好的，下面是实现自动随机生成一个迷宫，并能用键盘控制小球完成走迷宫游戏的Python代码。这里我们同样使用pygame和随机数模块random。

import pygame
import random

# 定义迷宫的大小和单元格的大小
MAZE_WIDTH = 20
MAZE_HEIGHT = 15
CELL_SIZE = 30

# 定义迷宫的二维数组
maze = [[0 for y in range(MAZE_HEIGHT)] for x in range(MAZE_WIDTH)]

# 定义迷宫的起点和终点
start_pos = (0, 0)
end_pos = (MAZE_WIDTH - 1, MAZE_HEIGHT - 1)

# 随机生成迷宫
def generate_maze():
    # 初始化迷宫的基本结构
    for x in range(MAZE_WIDTH):
        for y in range(MAZE_HEIGHT):
            if x == 0 or x == MAZE_WIDTH - 1 or y == 0 or y == MAZE_HEIGHT - 1:
                maze[x][y] = 0
            else:
                maze[x][y] = 1

    # 随机打通迷宫的墙壁
    for x in range(1, MAZE_WIDTH - 1):
        for y in range(1, MAZE_HEIGHT - 1):
            if random.randint(0, 2) == 0:
                maze[x][y] = 0

    # 设置起点和终点
    maze[start_pos[0]][start_pos[1]] = 1
    maze[end_pos[0]][end_pos[1]] = 1

# 绘制迷宫
def draw_maze(screen):
    for x in range(MAZE_WIDTH):
        for y in range(MAZE_HEIGHT):
            color = (255, 255, 255)
            if maze[x][y] == 0:
                color = (0, 0, 0)
            pygame.draw.rect(screen, color, (x * CELL_SIZE, y * CELL_SIZE, CELL_SIZE, CELL_SIZE))

# 绘制小球
def draw_ball(screen, pos):
    x, y = pos
    pygame.draw.circle(screen, (255, 0, 0), (x * CELL_SIZE + CELL_SIZE // 2, y * CELL_SIZE + CELL_SIZE // 2), CELL_SIZE // 2)

# 判断小球是否能够移动
def can_move(pos, direction):
    x, y = pos
    if direction == pygame.K_UP:
        if y > 0 and maze[x][y - 1] == 1:
            return True
    elif direction == pygame.K_DOWN:
        if y < MAZE_HEIGHT - 1 and maze[x][y + 1] == 1:
            return True
    elif direction == pygame.K_LEFT:
        if x > 0 and maze[x - 1][y] == 1:
            return True
    elif direction == pygame.K_RIGHT:
        if x < MAZE_WIDTH - 1 and maze[x + 1][y] == 1:
            return True
    return False

# 判断小球是否到达终点
def is_end(pos):
    return pos == end_pos

# 主函数
def main():
    pygame.init()
    screen = pygame.display.set_mode((MAZE_WIDTH * CELL_SIZE, MAZE_HEIGHT * CELL_SIZE))
    pygame.display.set_caption("Maze Game")

    generate_maze()
    ball_pos = start_pos

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                return
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_UP and can_move(ball_pos, pygame.K_UP):
                    ball_pos = (ball_pos[0], ball_pos[1] - 1)
                elif event.key == pygame.K_DOWN and can_move(ball_pos, pygame.K_DOWN):
                    ball_pos = (ball_pos[0], ball_pos[1] + 1)
                elif event.key == pygame.K_LEFT and can_move(ball_pos, pygame.K_LEFT):
                    ball_pos = (ball_pos[0] - 1, ball_pos[1])
                elif event.key == pygame.K_RIGHT and can_move(ball_pos, pygame.K_RIGHT):
                    ball_pos = (ball_pos[0] + 1, ball_pos[1])

        screen.fill((255, 255, 255))
        draw_maze(screen)
        draw_ball(screen, ball_pos)
        pygame.display.flip()

        if is_end(ball_pos):
            font = pygame.font.Font(None, 36)
            text = font.render("You Win!", True, (0, 255, 0))
            text_rect = text.get_rect(centerx=screen.get_width() // 2, centery=screen.get_height() // 2)
            screen.blit(text, text_rect)
            pygame.display.flip()
            pygame.time.delay(2000)
            generate_maze()
            ball_pos = start_pos

# 启动主函数
if __name__ == "__main__":
    main()

运行代码后，你可以使用方向键来控制小球移动，完成走迷宫的游戏。希望对你有帮助！
