I have some data that I gather in a custom Saver. On the pause screen UI, there's a Save Game button that calls this custom Saver. After I gather the necessary data, I call

Code: Select all

PersistentDataManager.ApplySaveData(gameData)

This, however, throws a Lua code error:

Code: Select all

Does my JSON include bad characters? I've been writing C# code for almost a decade now, but I have no experience with Lua, so I'm not sure where I'm going wrong here. Is my whole implementation bad?

Hi,

Saver components use the Save System. You don't need to call PersistentDataManager. Call these methods instead:

Code: Select all

PixelCrushers.SaveSystem.SaveToSlot(#);
...
PixelCrushers.SaveSystem.LoadFromSlot(#);

API Reference: SaveSystem

This is the flowchart that's at the bottom of the Save System manual page:

PersistentDataManager sits between "Dialogue System data" and "Dialogue System Saver". Dialogue System Saver uses PersistentDataManager to save and record the Dialogue System's internal data (variables, quest states, etc.).

Your own savers ("Other savers..." in the flowchart) don't need to worry about PersistentDataManager.

If you have any questions about this, just let me know.
