[1.9] Adding Data to Players

[Notunknown]

I am creating a Thaumcraft-style documentation book for my mod, where players research entries before being granted access. However, I am not certain on how to proceed. Obviously I need to store the data on the server and download it to the client when required. Should I be using capabilities, or something else entirely?

[Notunknown]

Capabilities are exactly the right choice.

 

Will I need to take any additional actions to sync client and server data, or do capabilities automatically do that?

[Notunknown]

You will need to do that yourself.

 

Yeah, I just remembered about the docs. One thing: Is my capability supposed to extend something? That was not made all that clear.
