Auto save with prefabs + playmaker, NullReferenceException

[ieatcolors]

Hello,

I am using Playmaker and EasySave3 to save my scene. I use a C# script to instantiate my prefabs into the scene. These prefabs have been marked for autosave, I have a ES3 Manager in the scene, auto saved is turned to on. The prefabs consist of a script, an FSM and some child gameobjects for visuals. I have also updated Easy Save earlier today. I am running Unity 2021.1.13f1.

I set up UI buttons to trigger Playmaker actions ES3 Auto Save Save and ES3 Auto Save Load. The Save action seems to work (no errors) but the Load action throws the following error:

Code: Select all

As another test, I have created an array of gameobjects (those same prefabs I instantiated) and tried to load and save these arrays. No issues using playmaker action Save All to save the array of gameobjects. Using Playmaker action Load All led to this error:

Code: Select all

Any ideas? Thanks for all of your help!

Hi there,

There's potentially an issue which will be resolved in our upcoming update which could cause this. If you private message me your invoice number I'll send it over.

All the best,
Joel

Thanks for the quick response. Just private messaged.

Hi Joel,

Thanks for sending that over. I have been trying to mess with it to see if this was something I was doing wrong from my end. I am still getting the same error.

Some other notes about my setup for the scene:

• My prefabs are not in the scene and have both the ES3 Prefab Script and ES3 Auto Save Script; they are instantiated at runtime

• I notice that the prefab count is on the ES3 Reference manager is incorrect and shows zero after stopping the game; it looses references

• Clicking Refresh button on reference manager also causes the prefab count to go to zero

• I have tried re-adding the references by right clicking prefab>>Easy Save 3>>Add References to manager, in which it then appears in the reference manager and the prefab count displays properly

• I've tried stopping and starting the scene and also using ES3 Auto save and load playmaker actions manually, neither work and show same error

I have also imported the example file (https://moodkie.com/forum/viewtopic.php?f=18&t=1468) into the same project and this works fine. See attached for images of my scene.

Hi there,

Is there a reference to the prefab you're instantiating in the scene prior to runtime, or do you load this dynamically using something like Resources?

Also is 'Add all prefabs to manager' enabled in Tools > Easy Save 3 > Settings? This is enabled by default.

All the best,
Joel

Hello, I am new to C#, so I am not sure what you mean by dynamically loading. Right now to create my prefabs at run time, I use playmaker send message to run the below instantiate script. I send another playmaker FSM to assign the scriptable object in the C# code. The script takes a prefab that is attached to a scriptable object. The prefab is instantiated at the mouse position for a grid building system.

My 'Add all prefabs to manager' was not enabled, so I just did that. The reference manager now shows the number of prefabs, but I do still get the same error.


Instantiated:

Code: Select all

    public static PlacedObject Create(Vector3 worldPosition, Vector2Int origin, FurnitureScriptableObject.Dir dir, FurnitureScriptableObject placedFurnitureSO)
    {
        Transform placedFurnitureTransform = Instantiate(placedFurnitureSO.prefab,
            worldPosition,
            Quaternion.Euler(0, placedFurnitureSO.GetRotationAngle(dir), 0)
            );

        PlacedObject placedObject = placedFurnitureTransform.GetComponent<PlacedObject>();
        placedObject.Setup(placedFurnitureSO, origin, dir);

        return placedObject;

    }

Hi there,

Please could you replicate this in a new, empty project containing only PlayMaker and Easy Save and a simple scene, and private message it to me with instructions.

All the best,
Joel

Hi Joel,

Thanks for following up. I created a new clean project per your request, and found that it was working! After some digging around, I found that the main difference between the new project and the old project was that the old project has an ES3type I made long ago but wasn't using. Deleting this and reimporting easy save 3 fixed the issue! Thanks for your help!
