maybe they mean solid open source netcode? Call of Duty famously used Quake 3 net code for a while. That engine was a great core to build from since Carmack made such solid stuff.

But then again, they're probably just a bot.

AFAIK (remember) Call of Duty was built on a modified Quake 3 engine long before it went open source

[newsclues]

IW Engine is based on the RtCW version of the id Tech 3 (Quake 3) engine they licensed.

What does Call of Duty use now?

[bananaboy]

Custom code still derived from q3

[shdh]

Its likely that every component of the engine has now been swapped out and almost no Q3 derived code exists.

Yeah I know, I work for Sledgehammer Games on cod. It's not that it's been swapped out, it's been rewritten and rewritten many times over the years. What I meant to imply (but didn't succeed in saying) was that for systems that were in q3a, if you knew the q3a code, then you would feel a sense of familiarity with those parts of the cod code.

I occasionally do some random spelunking for fun and while there's practically no code left, there are still a few small remnants like the odd comment or function signature (or partial signature) that are still there, and some that even date back to Quake 1!

That's really cool, thanks for sharing that information!
