How to change the scene in Unity after all enemies have been killed?

Question

I have a script that counts how many enemies are left and changes the scene when there are no more enemies. However, it doesn't work, and I can't find the error. I have a really similar script (it's almost the same to be honest) that works perfectly, but I can't figure out how to make this script work.

Here's the code:

public class enemyCountt : MonoBehaviour {

    public static int enemiessCount = 5;

    void Start() {}

    void Update(){
        print("Enemy count is " + enemiessCount ); 

        if(enemiessCount <= 0)
        {
            SceneManager.LoadScene ("bonus");
        }
    }
}

and this is attached to the bullet script:

if (collision.gameObject.tag == "Enemy") {
    enemyCountt.enemiessCount --; 
}

Answer 1

You are using 2 different scripts, so just enemyCountt.enemiessCount --; wont work. if both scripts are on the same gameobject, then you can use gameObject.enemyCountt.enemiessCount --;

if these arent in the same gameobject, then you can make a reference from the other gameobject with the other script

     public GameObject OtherObject;

     void Update(){
     if (collision.gameObject.tag == "Enemy") {
         OtherObject.enemyCountt.enemiessCount --; 
     }

then you have in the object, where you added the script, a free field, where you can drag & drop your GameObject with the script "enemyCountt" and then it should work, but I'm not quite sure
