【Unity3D游戏开发】—— PlayerPrefs类实现本地持久化数据存储

using UnityEngine;
using System.Collections;

public class Scene1 : MonoBehaviour {

    //储存持久化数据显示
    //可以保存3种类型，浮点型，整型，字符串型
    public string Grade;
    public string Age;
    public string Name;

    //图片贴图
    public Texture image;

    void Start()
    {
        //得到存储的数据
        Grade = PlayerPrefs.GetFloat("mGrade", 0.0f).ToString();
        Age = PlayerPrefs.GetInt("mAge", 0).ToString();
        Name = PlayerPrefs.GetString("mName", "");
    }

    void OnGUI()
    {
        //一张图片贴图
        GUI.DrawTexture(new Rect((Screen.width - image.width) / 2, 20, 120, 120), image);
        //输入姓名
        GUILayout.Label("----请输入姓名-----", GUILayout.Height(25));
        Name = GUILayout.TextField(Name, GUILayout.Height(25));
        //输入年龄
        GUILayout.Label("----请输入年龄-----", GUILayout.Height(25));
        Age = GUILayout.TextField(Age, GUILayout.Height(25));
        //输入成绩
        GUILayout.Label("----请输入成绩-----", GUILayout.Height(25));
        Grade = GUILayout.TextField(Grade, GUILayout.Height(25));

        //提交并跳转至下一个场景
        if (GUILayout.Button("提交",GUILayout.Height(25)))
        {
            //储存数据
            PlayerPrefs.SetString("mName", Name);
            PlayerPrefs.SetInt("mAge", int.Parse(Age));
            PlayerPrefs.SetFloat("mGrade", float.Parse(Grade));

            //跳转到场景2
            Application.LoadLevel("scene2");
        }
    }
}

using UnityEngine;
using System.Collections;

public class Scene2 : MonoBehaviour {

    //储存持久化数据显示
    //可以保存3种类型，浮点型，整型，字符串型
    public string Grade;
    public string Age;
    public string Name;

    //图片贴图
    public Texture image;

    void Start()
    {
        //得到存储的数据
        Grade = PlayerPrefs.GetFloat("mGrade", 0.0f).ToString();
        Age = PlayerPrefs.GetInt("mAge", 0).ToString();
        Name = PlayerPrefs.GetString("mName", "");
    }

    void OnGUI()
    {
        //一张图片贴图
        GUI.DrawTexture(new Rect((Screen.width - image.width) / 2, 20, 120, 120), image);

        //显示名字
        GUILayout.Label("姓名： " + Name, GUILayout.Height(25));
        //显示年龄
        GUILayout.Label("年龄： " + Age, GUILayout.Height(25));
        //显示成绩
        GUILayout.Label("成绩： " + Grade, GUILayout.Height(25));


        //清除数据
        if (GUILayout.Button("清除数据", GUILayout.Height(25)))
        {
            PlayerPrefs.DeleteAll();
        }

        if (GUILayout.Button("返回上一页", GUILayout.Height(25)))
        {
            //返回场景1
            Application.LoadLevel("scene1");
        }
    }
}

将上述代码分别绑定在两个场景的摄像机上即可

点击File -> Build Settings.. 添加这两个场景

然后Build and Run就能生成并运行了

 

我们的小例子就完成了。unity的数据存储还算是比较简单的。具体还有什么看不见的坑，以后掉进去了才会知道吧。
