使用Python的pygame库实现迷宫游戏

关于Python中pygame游戏模块的安装使用可见 https://blog.csdn.net/cnds123/article/details/119514520

先给出效果图：

这个游戏每次运行能自动随机生成迷宫布局。

在这个游戏中，玩家将使用键盘箭头键来移动，并且目标是从迷宫的左上角移动到右下角。

源码如下：

import pygame
import random
import time  # 导入time模块用于移动延迟# 迷宫生成算法中使用的方向常量
UP = (0, -1)
DOWN = (0, 1)
LEFT = (-1, 0)
RIGHT = (1, 0)# 初始化pygame
pygame.init()# 设置迷宫的行数和列数
ROWS, COLS = 10, 10 #你可以根据需要调整迷宫的大小
# 设置每个单元格的大小
SIZE = 40
# 创建游戏窗口
WIN = pygame.display.set_mode((COLS * SIZE+2, ROWS * SIZE+2))
pygame.display.set_caption("迷宫游戏")# 设置颜色常量
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)
RED = (255, 0, 0)# 定义单元格类

def generate_maze(rows, cols):# 创建单元格网格grid = [[Cell(row, col) for col in range(cols)] for row in range(rows)]# 随机选择一个单元格作为当前单元格current_cell = grid[random.randint(0, rows - 1)][random.randint(0, cols - 1)]current_cell.visited = True# 使用栈来跟踪单元格路径stack = [current_cell]while stack:# 获取当前单元格的未访问邻居neighbors = []for direction in [UP, DOWN, LEFT, RIGHT]:next_row = current_cell.row + direction[1]next_col = current_cell.col + direction[0]if (0 <= next_row < rows and0 <= next_col < cols andnot grid[next_row][next_col].visited):neighbors.append(grid[next_row][next_col])if neighbors:# 随机选择一个未访问的邻居next_cell = random.choice(neighbors)next_cell.visited = True# 移除墙壁current_cell.remove_walls(next_cell)# 将当前单元格压入栈stack.append(current_cell)# 将选择的邻居设置为当前单元格current_cell = next_cellelse:# 如果没有未访问的邻居，则回溯current_cell = stack.pop()return grid# 游戏循环

这段代码首先定义了一个Cell类，用于表示迷宫中的单个单元格。迷宫生成算法使用了深度优先搜索算法来生成迷宫。每个单元格知道自己的位置以及哪些墙是存在的。generate_maze函数创建了一个单元格网格，并从一个随机单元格开始，追踪它的路径直到所有单元格都被访问过。最后，main函数包含了游戏的主循环，它不断地绘制迷宫并处理退出事件。

player_pos变量来跟踪玩家的位置，并在游戏循环中检查键盘输入来移动玩家。墙壁检查确保玩家不能穿过墙壁。游戏结束条件是当玩家到达迷宫的右下角结束位置时，会打印一条消息并退出游戏。

你可以根据需要调整迷宫的大小。
