Android IOS ##StreamingAssets路径##XML操纵

我们在读写例如XML和TXT文件的时候，在电脑上和手机上路径不一致，造成了很多麻烦，其实有个简单的方法，在项目工程中新建一个StreamingAssets文件夹，把你的XML和TXT文件放到这里。

注：其实每个平台的路径都可以是Application.streamingAssetsPath+"/Achievement.xml"。但是android平台必须要用WWW加载，其他的平台貌似也可以的

移动平台操控读取XML！

 using UnityEngine;
 using System.Xml;
 using System.Collections;
 using System.IO;
 public class XmlLoad
 {
     /// <summary>
     /// XML 文档实例化
     /// </summary>
     private XmlDocument xmlDoc=new XmlDocument();
     private string data = "";
     private TextAsset asset;
     public int zombiesHp = 0;
     public float zombiesSpeed = 0f;
     /// <summary>
     /// 加载
     /// </summary>
     public void ShowData(string jsName)
     {
         asset = (TextAsset)Resources.Load("test", typeof(TextAsset));
         data = asset.text;
         xmlDoc.LoadXml(data);
         XmlElement root = xmlDoc.DocumentElement; // 得到根节点
         foreach (XmlNode node in root.ChildNodes)
         {
             XmlElement xe = (XmlElement)node;
             if (node.Name == jsName)
             {
                 zombiesHp =int.Parse(xe.GetAttribute("hp"));
                 zombiesSpeed = int.Parse(xe.GetAttribute("speed"));
             }
         }
     }
 }
