unity StreamingAssets路径

  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。

using UnityEngine; using System.Collections; using System.Xml; using System.Xml.Serialization; using System.IO; using System.Text;  public class Reward   {    public int taskNo;      public Task[] task = new Task[15];   public Attribute attribute;    public Reward () {}    public struct Task   {   [XmlAttribute("taskReward")]   public string taskReward{ get; set;}   public Id id1;   public Id id2;      public Id id3;   }   public struct Id   {  [XmlAttribute("flag")]   public bool flag{ get; set;}   [XmlAttribute("name")]   public string name{ get; set;}  [XmlText()]  public string description{get;set;}   }  }public class AchievementManager: MonoBehaviour {    Reward reward ;    FileInfo fileInfo;   string _data;    void Start ()    {         reward = new Reward();  LoadXML();   }    void LoadXML()    {   if(Application.platform == RuntimePlatform.IPhonePlayer)  { fileInfo = new FileInfo(Application.dataPath + "/Raw/" + "Achievement.xml");   StreamReader r = fileInfo.OpenText();          _data = r.ReadToEnd();          r.Close();   }  else if(Application.platform == RuntimePlatform.Android)  { fileInfo = new FileInfo(Application.streamingAssetsPath+"/Achievement.xml");     StartCoroutine("LoadWWW");  }  else  { fileInfo = new FileInfo(Application.dataPath + "/StreamingAssets/"+ "Achievement.xml");  StreamReader r = fileInfo.OpenText();          _data = r.ReadToEnd();          r.Close();       }    if(_data.ToString() != "")       {          reward = (Reward)DeserializeObject(_data);                    }    }   void OnGUI()   {   GUI.Label(new Rect(0,0,Screen.width,Screen.height),"data:"+_data);    if(Input.GetKey(KeyCode.Space)){Application.Quit(); }   }IEnumerator LoadWWW(){WWW www = new WWW(Application.streamingAssetsPath+"/Achievement.xml");yield return www;_data =www.text;}   public void Save()   {           _data = SerializeObject(reward);  StreamWriter writer;       fileInfo.Delete();      writer = fileInfo.CreateText();       writer.Write(_data);      writer.Close();    }   string UTF8ByteArrayToString(byte[] characters)    {            UTF8Encoding encoding = new UTF8Encoding();       string constructedString = encoding.GetString(characters);       return (constructedString);    }     byte[] StringToUTF8ByteArray(string pXmlString)    {       UTF8Encoding encoding = new UTF8Encoding();       byte[] byteArray = encoding.GetBytes(pXmlString);       return byteArray;    }     // Here we serialize our Reward object of reward    string SerializeObject(object pObject)    {  string XmlizedString = null;       MemoryStream memoryStream = new MemoryStream();       XmlSerializer xs = new XmlSerializer(typeof(Reward));       XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);       xs.Serialize(xmlTextWriter, pObject);       memoryStream = (MemoryStream)xmlTextWriter.BaseStream;       XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());       return XmlizedString;    }     // Here we deserialize it back into its original form    object DeserializeObject(string pXmlizedString)    {       XmlSerializer xs = new XmlSerializer(typeof(Reward));       MemoryStream memoryStream = new MemoryStream(StringToUTF8ByteArray(pXmlizedString));       XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);       return xs.Deserialize(memoryStream);    } }

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，自己试试哈，呵呵~~~
