Quake2 Engine - Code Format

yes, it seems that way (http://www.gamedev.net/community/forums/topic.asp?topic_id=108327).

That thread discusses doom3 and unreal.

yup, q2 is written completely in C with some ASM

check it out, its on the idsoftware ftp

Why does it matter what Quake 2 uses? Most people will tell you that the coding style of JC is rubbish anyway... I don''t know, I''ve never looked myself.

If I had my way, I''d have all of you shot!

Is the Quake2 engine written in C as described in ''The C Programming Language'' by Kernighan and Ritchie or are there elements of C++ mixed in there?

---

What do you mean by ''elements of C++''?

And yet he seems to be getting stuff done... and driving a Ferrari.

As for the 'elements of C++', there are none, it's straight C, so pure and clean you could baptize your children with it.

yeah, but it also notes that doom3 is one of the first of JC''s projects that has any C++ code in it. that means that q2 does use C only. well, according to that thread, anyway.

I was a little unsure about how msvc determined whether code was C or C++ and I thought they might be mixed together. Now I realize the file extension .c or .cpp designates what 'format' the code is in.

And now that I realize it's straight C, I can keep the Kernighan and Ritchie book handy as I go through the code. Are there any other reference books I should look at for C? There are so many for C++ but the K+R is the only popular one I've found for C.

I''m almost certain that file with a .c extension will be compiled as C++ files in VC. I''m still wondering what you consider these ''elements of C++'' that might be included in C code. Quake II was indeed written completely in C. It also somewhat emulated object-oriented design through the use of structs, but there is still no inheritance or polymorphism. This is because JC, until recently, believed that the overhead was unacceptable proportional to the gains.

Nah, a .c file is compiled as straight C. I think there''s a compiler switch to force it one or the other as well, but I can''t remember what it is.

Well you could always try addign a cout << "" statment to your C sourcefile, and compiling it in MSVC.

Dean''s right. My bad. The way it tells the difference is via the "__cplusplus" define, and I''m assuming it''s also the reason for "extern "C"" or whatever that is...
