using System.Collections.Generic;
using UnityEngine;

namespace RPG.Resources
{
    public class Experience : MonoBehaviour,ISaveable
    {
        [SerializeField] float experiencePoints = 0;

      
        public void GainExperience(float experience)// 获得经验
        {
            experiencePoints += experience;
        }

        public float GetPoint()//返回经验的点数 -用于UI显示
        {
            return experiencePoints;
        }


        public object CaptureState()
        {
            return experiencePoints;
        }

        public void RestoreState(object state)
        {
            experiencePoints = (float)state;
        }
    }
}
