You need to pass somehow a reference to an instance of Enemy object. — SnowGroomer, Jun 25 '21 at 18:00

The problem lies in this line of code

 if(Enemy.points == 3){

You attempt to access the points variable directly from a class and not from an object. You need to get a reference of the enemy game object.

If you don't want to assign them at runtime then take a look at the modified door script

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

public class door : MonoBehaviour
{

   public Enemy myEnemy; //assign this in the inspector
    
    void Update(){
        if(myEnemy.points == 3){
            print("yeee");
        }
    }
}
