数据操作之PlayerPerfs

这个PlayerPerfs类是Unity3D自带的小型化的数据存储的类，对于小数据完全适合

using UnityEngine;  
using System.Colliections;  
  
public class PlayerPerfsExample:MonoBehaviour{  
  
  
    void Example()  
    {  
        //设置键值和值  
        PlayerPerfs.SetInt("keyInt",10);  
        PlayerPerfs.SetFloat("keyFloat",10.2f);  
        PlayerPerfs.SetString("keyString","lmzqm");  
  
        //获取键值如果不存在该键值就返回默认值0  
        PlayerPerfs.GetInt("keyInt",0);  
        PlayerPerfs.GetFloat("keyFloat",0);  
        PlayerPerfs.GetString("keyString","0");  
  
        PlayerPerfs.DeleteAll();//删除所有键值  
        PlayerPerfs.DeleteKey("keyInt");//删除某个键值  
          
        bool exist = PlayerPerfs.HasKey("keyInt");//判断是否存在键值  
    }  
}
