Accessing persistent data without running the game

Hello,
Is it possible to access persistent data without running the game?
For instance, I want to save/load states while in Editor without playing the session.
Code: Select all
saveObject.dialogueSystemSave = PixelCrushers.DialogueSystem.PersistentDataManager.GetSaveData();
Code: Select all
PixelCrushers.DialogueSystem.PersistentDataManager.ApplySaveData( saveData.dialogueSystemSave );
Also, where can I manually set/see the persistent data?
Thank you

Hi,
Are you using the Dialogue System's
save system? If so, then it depends on which saved game data storer you're using. Here's an example of using PlayerPrefsSavedGameDataStorer and JsonDataSerializer:
Code: Select all
var storer = FindObjectOfType<PlayerPrefsSavedGameDataStorer>();
var playerPrefsKey = storer.GetPlayerPrefsKey(slotNumber);
var rawData = PlayerPrefs.GetString(playerPrefsKey);
var savedGameData = JsonUtility.FromJson<SavedGameData>(rawData);
Debug.Log("Game was saved in scene: " + savedGameData.sceneName);
var rawPositionData = savedGameData.GetData("PlayerPosition");
var positionData = JsonUtility.FromJson<PositionSaver.PositionData>(rawPositionData);
Debug.Log("Player position: " + positionData.position);
If you're not using the save system, and if you're only using PersistentDataManager.GetSaveData(), then this function only returns a string. It's up to you to do something with the string. The string is Lua code, so you can print it out to see what it contains. Or you can create a Lua object at runtime and run it through that.

Hello,
Yes, I am not using Save System. The part I am asking is...
If I call this function in Editor (while not playing)
Code: Select all
PixelCrushers.DialogueSystem.PersistentDataManager.GetSaveData();
It throws an error.

If I run the code while playing it does not.
I just want to call these 2 functions without playing the session.
Code: Select all
PixelCrushers.DialogueSystem.PersistentDataManager.GetSaveData();
Code: Select all
PixelCrushers.DialogueSystem.PersistentDataManager.ApplySaveData( saveData.dialogueSystemSave );

Hi,
If the game isn't running, then there is no save data to get. So PersistentDataManager.GetSaveData() won't work.
What do you want to accomplish?

I want to go into save state A from B sometimes just for debug purposes.
Like switching datasets in Scriptable Objects

What if you use PersistentDataManager.GetSaveData() during play to record a state. Then save this string somewhere, such as in EditorPrefs or PlayerPrefs.
Add another script that can retrieve this string and apply it using PersistentDataManager.ApplySaveData() during play.

Maybe I should do that.
Besides that, if I want to set some value manually- where do I want to go?

Here are ways to set a Lua value manually:
- Use the "Run" field at the bottom of the Dialogue Editor's Watches panel.
- Add a Lua Console to your scene. Press ~+L to open it during play. Then enter Lua code. To view a value, use "return". Example:
Code: Select all
Variable["x"] = 42
return Variable["x"]
- In a C# script, use DialogueLua.SetVariable:

Oh thank you,
and is there any UI as well?
like seeing the list of data in one place? and edit them there? (while not running the game)

The save data is Lua code. You can look at it in a text editor. It will look similar to:
Code: Select all
Variable = { Alert = "", x = 42 }; Actor["Player"] = { Name = "Player", IsPlayer = true } ...
