This error is from the Door script I’m trying to get working on
so here’s the code also I’m new at Unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Door_script : MonoBehaviour
{
    GameObject player;
private Animator _Animator; // Use this for initialization
void Start ()
{
_Animator = GetComponent <Animator >(); //put Animator in angle brackets
}


void OnCollisionEnter(Collision col, ref bool character_nerby)
    {
        if(col.gameObject == player)
        {
            _Animator.SetBool("character_nerby", true);
            }

    }
    void OnCollisionExit(Collision col, ref bool character_nerby)
    {
        if(col.gameObject == player)
        {
            _Animator.SetBool("character_nerby", false);
        }
    }
}

Go look at the documentation for this function. It’s not one you can willy-nilly add arguments to, as the warning implies. The reason is that Unity is calling this function, not you. If you want your own custom function, then you need to name it something different.
