Singleton script

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

public class Sc03Singletion : MonoBehaviour
{

    // The singleton pattern 
    static Sc03Singletion instance;

    public static Sc03Singletion Instance()
    {

        if (instance==null)
        {
            instance = new Sc03Singletion();
        }

        return instance;
    }


    public void AnimBegin(GameObject obj,Animator ani,string state)
    {
        ani = obj.GetComponent<Animator>();

        if (ani.speed==0)
        {
            ani.speed = 1;
        }
        ani.SetBool(state,true);

    }

    public void AnimEnd(GameObject obj, Animator ani, string state)
    {

Door switch script ：

         }
         Ani_Door.SetBool(state, true);*/


        // The singleton pattern 

        Sc03Singletion.Instance().AnimBegin(this.gameObject,Ani_Door,state);

    }

    public void CloseDoor()

    }
}

Light control script ：

    }

    public void LightOff()
    {
        Sc03Singletion.Instance().AnimEnd(this.gameObject, Ani_Light, state);
    }
}
