SaveSystem load doesn't load, only resets scene

[gblekkenhorst]

I've set up the save system following the "Dialogue System for Unity 2.x Save System" Youtube tutorial, so I have Save System, Json Data Serializer, Player Prefs Saved Game Data Storer and Dialogue System Saver on the Dialouge Manager. I have a pause menu with Save and Load buttons, which are calling SaveSystem.SaveToSlot(0); and SaveSystem.LoadFromSlot(0); respectively.

Saving seems to work because PlayerPrefs updates to the right DS variables when I check after saving. But LoadFromSlot just resets the scene and all the variables are set to initial states.

Here's the console message on load:

Code: Select all

Save System: Loading scene GossipMode
UnityEngine.Debug:Log (object)

UnityEngine.SetupCoroutine:InvokeMoveNext (System.Collections.IEnumerator,intptr)

I don't know if it's important, but Player Prefs Saved Game Data Storer Saved Games is empty while in the video it showed a save file. Using 22.2.49 in Unity 2022.3.13.

Hi Gillian,

Did you assign a unique key to the Dialogue System Saver? (I usually use "ds", but anything's fine as long as it's unique from other savers.)

Try ticking the Save System's Debug checkbox and PlayerPrefs Saved Game Data Storer's Debug checkbox. This will log the saved game data to the Console.

When you do this and save and load, do you see the variables in the compact JSON output?

Are there any errors or warnings in the Console?

I figured it out! By making sure I was testing everything I could think of before replying to you. I had a Dialogue Trigger that was set to trigger On Start, which called a convo that set all the starting variables, so it overwrote everything each time. Is there a built in way in DS to differentiate a "new game" start from a "loaded game" start? Especially from code?

Hi,

If you absolutely need to differentiate between a new game or reloaded game when a scene starts, please see: Save System: Init scene when not loading a save game

Otherwise, it might be simpler to initialize the variables when the player clicks a UI Button (or similar) to start a new game, rather than relying on a Dialogue System Trigger set to OnStart in the gameplay scene.
