Does anyone know whether Doom 3 will be written in C or C++?

[Tim Rennie]

According to this interview, yes. I vaguely remember some statements about the renderer still being C, but I can't seem to find a source.

EDIT: Er... by 'yes' I mean 'C++'. me st00pid.

Ah, thanks!

Of course, I dought the source will go public immediatly

Or for ages. The Quake3 engine is still being licensed even now.

Is this to say that quake III was created in C? Or...wait...i seem to recall vaguely that it was made on something else. Can someone refresh my RAM please?

[Tim Rennie]

The Quake3 game side stuff was definitely C. Afaik, the engine was C too, but I obviously can't confirm this :]

Doom III is the first id Software game written in C++. AFAIK, everything that came before was either ANSI C or assembly code. To further prove this, here's a screenshot of Jim Dose's desktop, early in Doom III's development. As you can see, he's using MS Visual C++.

Thanks FlatHead. I was looking for the shot but couldn't find it.

Just that wouldn't prove much, as id has been using MSVC++ for quite a while now. MSVC++ works just fine for compiling C code.

However, what's shown in the screenshot is indeed C++.

I just googled '"doom 3" desktop dose' and it was on top of the list.

whoa, how can you write an entire game in assembly code?

That should've been "and", not "or". id Software's previous engines were written in C and ASM, ASM only being used for really speed-critical stuff such as inner rendering loops.

But it is possible to write games in assembly code. Go back a few console generations and you'll find that's how video games were made.
