NullReferenceException for RPG.Core.Health.Die()

If an anemy is dead I get a NullRefernceException when the game starts or I switch to a level with dead characters in it.

I’ve tried saving and loading manually with the “s” and “l” buttons and it works great. But if I load the game or a scene I get “Loading from…” followed by the following error.

RPG.Core.Health.Die () (at Assets/Scripts/Core/Health.cs:44)
RPG.Core.Health.RestoreState (System.Object state) (at Assets/Scripts/Core/Health.cs:58)
RPG.Saving.SaveableEntity.RestoreState (System.Object state) (at Assets/Scripts/Saving/SaveableEntity.cs:37)
RPG.Saving.SavingSystem.RestoreState (System.Collections.Generic.Dictionary`2[TKey,TValue] state) (at Assets/Scripts/Saving/SavingSystem.cs:68)
RPG.Saving.SavingSystem.Load (System.String saveFile) (at Assets/Scripts/Saving/SavingSystem.cs:24)
RPG.Saving.SavingWrapper.Load () (at Assets/Scripts/Saving/SavingWrapper.cs:30)
RPG.SceneManagement.Portal+d__9.MoveNext () (at Assets/Scripts/SceneManagement/Portal.cs:53)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)

And I was just about to paste my code into this section when I realized that I had the following in my Health-class

public void Start()
            animator = GetComponent<Animator>();

So changed to Awake instead to make sure the animator is connected before loading happens.

public void Awake()
            animator = GetComponent<Animator>();

I thought I’d post this anyway If anyone else has a similar problem


Yes, once we get into the SavingSystem, it’s important to cache references in Awake(0 whenever possible.
