Unity读取CSV文件生成迷宫

Unity读取CSV文件生成迷宫

Unity利用C#的文件流读入文件生成迷宫
1.首先我们编写一个CSV文件，储存我们的迷宫数据
打开Sublime Text编写一个迷宫的文件，保存为UTF_8格式，不然Unity无法找到此文件。

2.打开Unity，在Assets下创建Resource文件夹

3.将我们保存好的文件复制到Resources文件夹下

4.编写生成迷宫的脚本Map.cs

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

public class Map : MonoBehaviour {


	void Start () {
        BuildMap();
	}
	
	void Update () {
		
	}

    void BuildMap()
    {
        TextAsset textAsset = (TextAsset)Resources.Load("Map");
        string[] map_row_string = textAsset.text.Trim().Split('\n');
        int map_row_max_cells = 0;
        List<List<string>> map_Collections = new List<List<string>>();
        for(int i=0;i<map_row_string.Length;i++)   //读取每一行的数据
        {
            List<string> map_row = new List<string>(map_row_string[i].Split(','));
            if (map_row_max_cells < map_row.Count)
            {
                map_row_max_cells = map_row.Count;
            }
            map_Collections.Add(map_row);
        }
        //生成一个刚好放Cube的Plane
        GameObject map_Plane = GameObject.CreatePrimitive(PrimitiveType.Plane);
        map_Plane.transform.position = new Vector3(0, 0, 0);
        //求其原始大小
        float map_Plane_original_x_size = map_Plane.GetComponent<MeshFilter>().mesh.bounds.size.x;
        float map_Plane_original_z_size = map_Plane.GetComponent<MeshFilter>().mesh.bounds.size.z;
        //缩放这个Map到所需大小，刚好和二维表匹配
        float map_Plane_x = map_row_max_cells / map_Plane_original_x_size;
        float map_Plane_z = map_Collections.Count / map_Plane_original_z_size;
        map_Plane.transform.localScale = new Vector3(map_Plane_x, 1, map_Plane_z);

        //在Plane上放Cube
        for(int i = 0; i < map_Collections.Count; i++)
        {
            for(int j = 0; j < map_Collections[i].Count; j++)
            {
                int cube_num = int.Parse(map_Collections[i][j]);
                for(int k = 0; k < cube_num; k++)
                {
                    GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
                    cube.transform.position = new Vector3(-(map_row_max_cells / 2) + i, (float)0.5 + k, -(map_Collections.Count / 2) + j);
                }
            }
        }
    }
}

5.在Unity场景中新建一个空物体GameObject，用来挂载脚本

6.运行游戏得到我们想要的迷宫效果
