You can always manipulate this, though. As programmers, you must work with the flexibility of the language.


Run a check for a players buddies, and have it save in a DB or a txt file or however you want to set it up. Since isbuddy only reads online buddies, you can have the place that you're storing a certain players buddies change when a buddy that is not already on the list triggers whatever it is that you're using to check for buddies. Eventually, a persons buddy list would have been saved anew wherever you wanted it stored, unless of course they never logged on the server at the same time as the person, in which case it shouldn't really matter since they're not active around the same time, so they shouldn't be counted in the data anyways.

It really depends on what you would want it for.
