Hi, I've been trying to figure out what the problem is. but since I'm new to both unity and coding, I really have no idea.... I have an error message as "NullReferenceException: Object reference not set to an instance of an object DestroyByContact.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Scripts/DestroyByContacts.cs41). I have explosion animations and sounds but they just don't disappear when colliding each other. help please!
