Core concepts & FAQ

What is a "Save Slot"

A slot is a specific instance of someone's save game. This typically includes info like health, room, coordinates, and other info you want to store about someone's play-through.

What is "Common"

Common is info shared between all save files. This often includes stuff like config, accessibility, and other settings you want to store separate from each slot.

How are my save files stored?

All data on your end is written as a GDScript file. This allows you to include variables, constants, functions, and more when building out your saves. When being written to disk, this data is converted into a JSON file and encrypted. This way there is no avenue for malicious code to be included in your save file, unlike the commonly used "Resource" method of saving. When a save file is loaded, this encrypted JSON is read and converted back into the original format so you can easily read from it like any other variable.

So, what about performance?

This is not as performant as manually writing out JSON saves or writing an entire resource to disk, but it is still very fast! The small reduction in performance is well worth it, considering you get smaller files, improved security, and a lot of convenience on your end as the developer.
