用unity写一个迷宫代码出来

好的，以下是一个简单的 Unity 迷宫生成器代码（基于深度优先搜索）：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MazeGenerator : MonoBehaviour
{
    public int width, height;
    public GameObject wallPrefab;
    public float wallLength = 1;

    private bool[,] visited;
    private List<GameObject> walls = new List<GameObject>();

    void Start()
    {
        visited = new bool[width, height];

        GenerateMaze(0, 0);

        // 删除外墙
        DestroyWall(0, height/2);
        DestroyWall(width/2, 0);
        DestroyWall(width-1, height/2);
        DestroyWall(width/2, height-1);
    }

    void GenerateMaze(int x, int y)
    {
        visited[x, y] = true;

        // 随机排序方向 
        List<int> directions = new List<int>() {0, 1, 2, 3};
        Shuffle(directions);

        foreach (int direction in directions)
        {
            int nx = x, ny = y;
            if (direction == 0) nx += 1;
            else if (direction == 1) nx -= 1;
            else if (direction == 2) ny += 1;
            else if (direction == 3) ny -= 1;

            // 如果新的位置在范围内且未访问，拆掉两格之间的墙，递归生成
            if (nx >= 0 && nx < width && ny >= 0 && ny < height && !visited[nx, ny])
            {
                GameObject wall = Instantiate(wallPrefab, transform);

                if (direction == 0) // right
                {
                    wall.transform.position = new Vector3(x*wallLength + wallLength/2, 0, y*wallLength);
                    wall.transform.localScale = new Vector3(wallLength, wallLength*2, 1);
                }
                else if (direction == 1) // left
                {
                    wall.transform.position = new Vector3(x*wallLength - wallLength/2, 0, y*wallLength);
                    wall.transform.localScale = new Vector3(wallLength, wallLength*2, 1);
                }
                else if (direction == 2) // up
                {
                    wall.transform.position = new Vector3(x*wallLength, 0, y*wallLength + wallLength/2);
                    wall.transform.localScale = new Vector3(1, wallLength*2, wallLength);
                }
                else if (direction == 3) // down
                {
                    wall.transform.position = new Vector3(x*wallLength, 0, y*wallLength - wallLength/2);
                    wall.transform.localScale = new Vector3(1, wallLength*2, wallLength);
                }

                walls.Add(wall);

                GenerateMaze(nx, ny);
            }
        }
    }

    void DestroyWall(int x, int y)
    {
        walls.Remove(walls.Find(wall => 
            wall.transform.position == new Vector3(x*wallLength, 0, y*wallLength)));
        Destroy(walls[walls.Count-1]);
    }

    static void Shuffle<T>(List<T> list) 
    {
        for (int i = list.Count - 1; i > 0; i--)
        {
            int j = Random.Range(0, i+1);
            T temp = list[i];
            list[i] = list[j];
            list[j] = temp;
        }
    }
}

在 Unity 中使用此代码创建一个空 GameObject，并为其添加 MazeGenerator 脚本，调整其参数以更改迷宫大小和墙体长度。生成的迷宫将自动删除四个外侧墙，并生成 Unity GameObjects 表示每一堵墙。
