最好用的数据存储Easy Save2讲解

转载：http://www.manew.com/thread-100109-1-1.html

 

今天抽时间学习了“Easy Save2”插件，版本v2.6.3  我个人觉得这个插件是做数据存取最好的插件~~可以取代PlayerPrefs。

它不仅可以直接存取PlayerPrefs支持的int、float、string、bool

还包括下图中所有类型

如果不指定位置，数据会存储在Application.persistentDataPath里

你也可以指定它的存储位置 类似下面这样

ES2.Save(data, "C:/Users/User/myFile.txt");    // 这里myFile.txt只存储data ES2.Save(transform.position, "C:/Users/User/myFile.txt?tag=myPosition");   // 在myFile.txt文件里插入key:myPosition对应value:transform.position transform.position = ES2.Load<Vector3>("C:/Users/User/myFile.txt?tag=myPosition");  //从myFile.txt文件里读取key:myPosition的value

也可以存储到web

public IEnumerator UploadMesh(Mesh mesh, string tag) {     // Create a URL and add parameters to the end of it.     string myURL = "http://www.server.com/ES2.php";     myURL += "?webfilename=myFile.txt&webusername=user&webpassword=pass";       // Create our ES2Web object.     ES2Web web = new ES2Web(myURL + "&tag=" + tag);       // Start uploading our data and wait for it to finish.     yield return StartCoroutine(web.Upload(mesh));       if (web.isError)     {         // Enter your own code to handle errors here.         Debug.LogError(web.errorCode + ":" + web.error);     } }   public IEnumerator DownloadMesh(string tag) {     // Create a URL and add parameters to the end of it.     string myURL = "http://www.server.com/ES2.php";     myURL += "?webfilename=myFile.txt&webusername=user&webpassword=pass";       // Create our ES2Web object.     ES2Web web = new ES2Web(myURL + "&tag=" + tag);       // Start downloading our data and wait for it to finish.     yield return StartCoroutine(web.Download());       if (web.isError)     {         // Enter your own code to handle errors here.         Debug.LogError(web.errorCode + ":" + web.error);     }     else     {         // We could save our data to a local file and load from that.         web.SaveToFile("myFile.txt");           // Or we could just load directly from the ES2Web object.         this.GetComponent<MeshFilter>().mesh = web.Load<Mesh>(tag);     } }

而且在存储和读取基本都是一条命令搞定，很方便。当然数据都是经过加密存储的

需要注意的是在存储Texture时，需要把图片类型改成“Advanced”，并勾选“Read/Write Enabled”

下面给大家分享下我测试的几个类型
