pso = persistable scriptable object

He's used this as the filetype but it really does not matter what you type in there.

{0} and {1} refer to the 2nd and 3rd parameters passed in.

Thank you very much. This helps so much.

Thank you Bro ;)

But we can't save references to other objects. This can work for simple types like ints, Lists etc. But It will break when you assign references to other Scriptable Objects or Prefabs. As Unity will only serialize their Instance IDs which is inconsistent between different sessions.
