errors
NullReferenceException: Object reference not set to an instance of an object
GameSession.AddToScore (System.Int32 pointsToAdd) (at Assets/Scripts/GameSession.cs:53)
BeerPickup.OnTriggerEnter2D (UnityEngine.Collider2D other) (at Assets/Scripts/BeerPickup.cs:14)
Brain hurts, lol
Worked fine util I added the score script now pickups don’t work again and I get null ref errors. So confused. I see what the errors are saying and where I made the mistakes but, I still don’t understand what I did wrong.
