Unity之读取配置表去加载物体

 每次加载物体都要去获得物体路径，然后在去加载，这样很不方便而且会出错。下面我把物体的名称和物体对应的路径读取到配置表里面，直接通过物体的名称去获得路径去加载物体。

一 配置表的制作

  *  Des:将资源的名称和路径对应
  ******************/
using UnityEngine;
using System.Collections;
using UnityEditor;
using System.IO;
using System.Collections.Generic;

public class CreateResInit : MonoBehaviour {

	    [MenuItem("CW/CreateResInit")]
        public static void CreateInit()
        {
            Dictionary<string, string> dic = new Dictionary<string, string>();

            string resPath = Application.dataPath + "/Resources/";
            string initPath = resPath + "Res.txt";

            if (File.Exists(initPath))
            {
                File.Delete(initPath);
            }

            CreateResInfo(resPath, ref dic);

            List<string> list = new List<string>();

            foreach (KeyValuePair<string,string > keyvalue in dic)
            {
                list.Add(keyvalue.Key + "=" + keyvalue.Value);
            }

            File.WriteAllLines(resPath + "/res.txt", list.ToArray());
            Debug.Log("生成完毕 ");
            AssetDatabase.Refresh();
        }


        public static void CreateResInfo(string path,ref Dictionary<string,string> dic)
        {
            DirectoryInfo dir = new DirectoryInfo(path);
            if(!dir.Exists)
            {
                Debug.Log("path:"+ path+"is not exit");
                return;
            }

            FileInfo[] files = dir.GetFiles();

            for (int i = 0; i < files.Length; i++)
            {
                FileInfo fileInfo = files[i];

                if(!(fileInfo.Name.IndexOf(".meta",0)>0))
                 {
                     string tmpPathDir = fileInfo.FullName.Replace("\", "/")
                        .Replace((Application.dataPath + "/Resources/"), "");
				    string  pathDir=  tmpPathDir.Split('.')[0];
					
                     string fileName = Path.GetFileNameWithoutExtension(fileInfo.Name);
					 
					
                     Debug.Log("fileName=" + fileName);
                    if(!dic.ContainsKey(fileInfo.Name))
                    {
                        dic.Add(fileName, pathDir);
                    }
                    else
                    {
                         Debug.LogError ("存在相同的资源名称 名称为：" + fileInfo.Name + "/path1=" + dic[fileInfo.Name] + "/ path2 =" + pathDir);
                    }
                 }
            }

            DirectoryInfo[] dirs = dir.GetDirectories();
            if(dirs.Length>0)
            {
                for (int i = 0; i < dirs.Length; i++)
                {
                    string tmpPath = Path.Combine(path,dirs[i].Name);
                    CreateResInfo(tmpPath, ref dic);
                }
            }
        }
}

  

 

2 测试根据物体名称去加载游戏物体

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Text;

public class TestLoad : MonoBehaviour {

	private Dictionary<string ,string> _resInitDic=new Dictionary<string, string>();

     void Start()
     {
         ReadResInit();
         foreach(KeyValuePair<string,string> kv in _resInitDic)
         {
             Debug.Log(kv.Key+"=="+kv.Value);
         }
         
     }

     void Update()
     {
         if(Input.GetKeyDown(KeyCode.W))
         {
            Instantiate(Resources.Load(_resInitDic["Cube"]));
         }
     }
    private void ReadResInit()
    {
        TextAsset txt=Resources.Load("res") as TextAsset;
   
        byte[] array = Encoding.ASCII.GetBytes(txt.text);  
        MemoryStream memoryStream=new MemoryStream(array);
        StreamReader  streamReader=new StreamReader(memoryStream);
        string line= streamReader.ReadLine();
       
        while(!string.IsNullOrEmpty(line))
        { Debug.Log(line);
            string[] arrys=line.Split('=');
            _resInitDic.Add(arrys[0],arrys[1]);
         
            line= streamReader.ReadLine();
        }

        
    }

}
