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

[C#]  纯文本查看 复制代码

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( "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

[C#]  纯文本查看 复制代码

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().mesh = web.Load(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

[C#]  纯文本查看 复制代码

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


public class SaveTest : MonoBehaviour {

    public Image image;

    public void Save()
    {
        ES2.Save(123, "IntData" );

        ES2.Save(1.23f, "FloatData" );

        ES2.Save( true , "BoolData" );

        ES2.Save( "abc" , "StringData" );

        ES2.Save( new Vector3(10, 20, 30), "Vector3Data" );

        // 存储transform
        GameObject go = new GameObject();
        go.transform.localPosition = new Vector3(10, 20, 30);
        go.transform.localScale = new Vector3(3, 3, 3);
        ES2.Save(go.transform, "TransformData" );

        // 存储数组
        int [] intArray = new int [3] { 3, 2, 1 };
        ES2.Save(intArray, "IntArrayData" );

        // 存储集合
        List< string > stringList = new List< string >();
        stringList.Add( "stringlist1" );
        stringList.Add( "stringlist2" );
        stringList.Add( "stringlist3" );
        ES2.Save(stringList, "StringListData" );

        // 存储字典
        Dictionary< int , string > stringDict = new Dictionary< int , string >();
        stringDict.Add(1, "a" );
        stringDict.Add(2, "b" );
        ES2.Save(stringDict, "StringDictData" );

        // 存储栈
        Stack< string > stringStack = new Stack< string >();
        stringStack.Push( "aaa" );
        stringStack.Push( "bbb" );
        ES2.Save(stringStack, "StringStackData" );

        ES2.SaveImage(image.sprite.texture, "MyImage.png" );
    }

    public void Load()
    {
        int loadInt = ES2.Load< int >( "IntData" );
        Debug.Log( "读取的int：" + loadInt);

        float loadFloat = ES2.Load< float >( "FloatData" );
        Debug.Log( "读取的float：" + loadFloat);

        bool loadBool = ES2.Load< bool >( "BoolData" );
        Debug.Log( "读取的bool：" + loadBool);

        string loadString = ES2.Load< string >( "StringData" );
        Debug.Log( "读取的string：" + loadString);

        Vector3 loadVector3 = ES2.Load( "Vector3Data" );
        Debug.Log( "读取的vector3：" + loadVector3);

        Transform loadTransform = ES2.Load( "TransformData" );
        Debug.Log( "读取的transform： 坐标" + loadTransform.localPosition + " 缩放" + loadTransform.localScale);

        // 读取数组格式存储
        int [] loadIntArray = ES2.LoadArray< int >( "IntArrayData" );
        foreach ( int i in loadIntArray)
        {
            Debug.Log( "读取的数组：" + i);
        }

        // 读取集合格式存储
        List< string > loadStringList = ES2.LoadList< string >( "StringListData" );
        foreach ( string s in loadStringList)
        {
            Debug.Log( "读取的集合数据：" + s);
        }

        // 读取字典格式存储
        Dictionary< int , string > loadStringDict = ES2.LoadDictionary< int , string >( "StringDictData" );
        foreach (var item in loadStringDict)
        {
            Debug.Log( "读取的字典数据： key" + item.Key + " value" + item.Value);
        }

        Stack< string > loadStringStack = ES2.LoadStack< string >( "StringStackData" );
        foreach ( string ss in loadStringStack)
        {
            Debug.Log( "读取的栈内数据：" + ss);
        }

        Texture2D tex = ES2.LoadImage( "MyImage.png" );
        Sprite temp = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(0, 0));
        image.sprite = temp;

        // 判断是否有该存储key
        Debug.Log(ES2.Exists( "IntData" ));

        // 删除存储key
        ES2.Delete( "IntData" );
    }


}
