NS2 Steamid to "real" Steamid

devicenull

NS2 outputs SteamID's in a weird format, it doesn't use the standard STEAM_0:x:y format, nor does it use the uint64 version of (which can be trivially converted back). What it does seem to give us is the m_unAccountId segment of the id. Happily, this can be <a href="http://hg.opensteamworks.org/open-steamworks/src/3761c6ead02e/Open%20Steamworks/CSteamID.h#cl-373" target="_blank">trivially converted</a> back to a normal steamid.

<!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->            steamid = int(ns2steamid)
            if steamid % 2 == 0:
                steamid = "STEAM_0:0:%i" % (steamid/2)
            else:
                steamid = "STEAM_0:1:%i" % (steamid/2)<!--c2--></div><!--ec2-->

Thanks for that, I had wondered what output it was giving me.

Is there a reason that NS2 ouputs in this format?

I'd guess they just figured it was unique enough, and didn't bother using either of the conversion options the CSteamID class provides. It's pretty weird though.

Edit: Oops, I had the logic backwards, fixed now.

It returns an integer (a double actually, as all numbers are floating points in Lua) that contains the digested form of the classic SteamID format, which can be computed like so: STEAM_0:n:x -> 2x+n. So if we have STEAM_0:1:12345678, the SteamID-number returned by the 'GetUserId'-method will be 2*12345678+1 = 24691357.<!--QuoteEnd--></div><!--QuoteEEnd-->
Slow-poke.

Huh, if that's the case then you really can't convert back to a normal steamid. That would suck.

The 'n' (the auth-server ID) in STEAM_0:n:x is either 0 or 1, so you can deduce it by looking at whether the digested-id is even (n = 0) or odd (n = 1).

So basically I need a PhD to convert a Steam ID? I don't get it. Is there any easier way for dumb people like me?

if anyone wants a pretty program/gui interface that allows you to convert 1 id at a time I can provide the link to it on my dropbox. it only does steam to ns2 thought.

Use this to convert steam ID to ns2 steam id : ideone.com/k0OLF

The ns2 wiki provide this information too : wiki.unknownworlds.com/ns2/Dedicated_Server#SteamID_Format

I threw this together last week. Maybe someone else finds it useful.
