NullReferenceException: Object reference not set to an instance of an object Plane.OnCollisionEnter2D (UnityEngine.Collision2D collision) (at Assets/Scripts/Plane.cs:37)

My Error Messages:

The referenced script on this Behaviour is missing!

The referenced script on this Behaviour (Game Object 'GameController') is missing!

My Control Script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

Is anim and GameOverText set? also use lazy ins$$anonymous$$d for your instance in combination with GetComponent<GameControl>():

 private GameControl _instance;
 public GameControl instance 
 { get {
 if (_instance != null) return _instance;
 _instance = this;
 return _instance;
 }
 }

No need for the awake method
