Hi. I'm trying to make an RPG mod using UT2003. Does anyone know how to save player information to the server so that players can be persistent? Thanks
Saving data to the server

Two Factor Authentication is now available on BeyondUnreal Forums. To configure it, visit your Profile and look for the "Two Step Verification" option on the left side. We can send codes via email (may be slower) or you can set up any TOTP Authenticator app on your phone (Authy, Google Authenticator, etc) to deliver codes. It is highly recommended that you configure this to keep your account safe.
Save their data in an .ini file, or use the SavePackage-related functions in GameInfo.
Or you could subclass TcpLink and code an interface to a database server such as MySQL.

one important note, when you are required to save a lot of info (e.g. a lot of users who's records have to be saved for a long time) you are better of saving the data off-site and request them from the off-site server when required to.
The only solution for that is to use a TcpLink subclass.

I think that would be the most efficient aproach anyway,
since you only need one Server with MySQL to store the Data.

a little side note, don't try to connect to the database directly, it'll be hell and a bad choice.
it's best to write an application that will connect to the database, you just connect to that application from your UT2003 server using your own protocol.

I just got mySQL up and running and I've built a DLL to talk to the server, but I have no idea how to integrate this into UT. I was guessing that I would just declare my exported functions as native in the .uc file, but do I need to have an engine license to do this? Thanks again
Yes... unless you can convince Epic to just give you access to the C++ headers. They have said they might do it in special cases (though I don't know whether they're still following this policy and whether your venture qualifies as such a "special case").JohnnyFantastic said:
Keep in mind that with a DLL you're restricting use of your mod to Windows clients and servers. That's a pretty harsh restriction.
You could solve that problem on several levels: Create an UnrealScript solution for communicating with the MySQL server; or set up a Perl or PHP script on a web server that acts as a layer between the game server and the MySQL server, and have the game server talk to that Perl or PHP script via HTTP.
You could try talking to the guys of the "King of the Server" mod. They have a stats system with a mySQL database working in UT2003 already.
OK, I've gotten rid of my dll altogether. Now I have a conduit program that talks with UT and the mySQL server (I've extended TcpLink as suggested) and everything is working fine. Thanks for all the help!
