Problem with saving ScriptableObject.

[Drandy007]

I'm trying to create a save system using EasySave3. I've got it to save when the variable (ScriptableObject data type) is set in the Inspector but, I need to create an instance of the scriptableobject at runtime, so can't be set in Inspector. It keeps coming up with

ArgumentNullException: Value cannot be null.

See attached image for code used. Is there a way to get it to work?

EDIT: I wasn't able to add all the snapshots that I took of the code so, here is some of the code I use.

Code: Select all

[SerializeField, ReadOnly]
private BaseState _currentState;
[SerializeField]
private IdleState _idleState;
[SerializeField]
private InteractState _interactState;

private void Start()
{
        #region FSM
        _idleState = ScriptableObject.CreateInstance<IdleState>();
        _interactState = ScriptableObject.CreateInstance<InteractState>();
        TransitionToState(_interactState);
	#endregion
}

Hi there,

Please could you provide me with information on the ScriptableObject you’re saving.

All the best,
Joel

Hi there,

Unfortunately I’m not able to replicate this from what you’ve sent.

First I would recommend you deleting any existing save data to see if this resolves the issue (Tools > Easy Save 3 > Clear PersistentDataPath).

If this doesn’t resolve the issue, please could you replicate it in a new, minimal project with a simple scene and private message it to me with instructions so I can see what is happening.

All the best,
Joel
