There is some interesting code in this release:

  void FuckingWellSetTheDocumentNameAndDontBloodyIgnoreMeYouCunt(LPCSTR psDocName)
  {
          if (gpLastOpenedModViewDoc)
          { // make absolutely fucking sure this bastard does as it's told... //
                  gpLastOpenedModViewDoc->SetPathName(psDocName,false);
                  gpLastOpenedModViewDoc->SetTitle   (psDocName);
          }
  }

My heart goes out to whatever programmer had to meet that deadline. There are a lot more gems in the source tree if you just run:

  egrep -R -i "fuck" *

Preferring sourceforge over github seems like an unusual choice, I didn't realise anyone still used it. It's a git repo too, I wonder why they did that?

I really don't understand the notion that SourceForge is dead and no one uses it anymore.

  http://sourceforge.net/projects/vlc
  http://sourceforge.net/projects/sevenzip/
  http://sourceforge.net/projects/emule/
  http://sourceforge.net/projects/filezilla/
  http://sourceforge.net/projects/npppluginmgr/
  http://sourceforge.net/projects/mingw/
  http://sourceforge.net/projects/azureus/
  http://sourceforge.net/projects/fceultra/ (Shameless plug)

Just to name a few. As a project admin of fceultra I cannot say that I'm 100% pleased with the UI of the bugtracker and the sf does have its quirks, but sourceforge has had a much better track record than github in respect to uptime. My question to you is "Why not?"

easytiger12y ago

yea but how old are those projects? I recognise some of those from the 90s

If you were starting new today you wouldnt choose it. It is a clusterfuck. How the owners can't see the writing on the wall and change is beyond me.

For all I know maybe they are

philbo12y ago

Tbh, I was speaking from a position of ignorance. The last time I used sourceforge properly must have been circa 2006/7 and it was an abomination then - clearly that is not the case now.

It definitely felt cleaner from a UI perspective today (albeit not github-clean) and the sluggish document load times that I remember were also not in evidence.

The open-source ecosystem is definitely richer for every hosting solution that exists, sf included, so if my comment seemed sneery I apologise. It just surprised me at the time is all.

Argorak12y ago

I reckon they just wanted to publish a tarball and Github is really bad at handling those.

ritonlajoie12y ago

Well, I don't think they'll accept any pull request, I think hosting these files on sourceforge won't make any difference.

Jedi Knight 2 and 3? No.

The two games are:

Dark Forces 3: Jedi Knight 2: Jedi Outcast

Dark Forces 4: Jedi Knight 3: Jedi Outcast 2: Jedi Academy

Get it right, people.

prg31812y ago

Even with your reasoning "Jedi Knight 2" and "Jedi Knight 3" were the games that were open sourced (Outcast and Academy). I would love to see Dark Forces II: Jedi Knight get open sourced by LucasArts however :)

I know this is terribly pedantic, but seeing the name of the blog like that in the HN title rubs me the wrong way.

larrydavid12y ago

It's not pedantic at all, I thought the same.

I have no idea why it's necessary at all. In fact why not get rid of the blog spam altogether and link straight to the code. Yes, I realise RPS isn't exactly a small site and has quite the following (which seems to extend to HN as well, apparently), but their article adds nothing of real value apart from a quote that was pulled from another article on Kotaku.

tomrod12y ago

How would someone go about compiling this? (More looking for resource/tutorial, running Ubuntu).

philbo12y ago

Judging from the `.dsw` file at the base of the code directory, it looks like you need to build it in MS Visual Studio.

TobbenTM12y ago

There is also the matter of missing assets.

Searching 1897 files for "goto " ... 603 matches across 121 files

cocks gun, blows brains out

(Yes I know the evil goto supposedly has its time and place, blah blah blah)

kabdib12y ago

Use of "structured gotos" for error handling is perfectly reasonable. Internal returns are far, far worse sources of error (mostly resource leaks, in my experience). Having functions with single exit points and avoiding contortions that involve extra control variables is better than the mindless avoidance of 'goto'.

Goto is just fine if it is used responsibly.

Jare12y ago

If you are going to write functions like this [1], gotos are not your worst problem. :)

I'm equally repulsed by huge, highly nested functions. However, I'd have to say that the game play provided by this function was one of my favorite parts of Jedi Outcast.

qznc12y ago

What exactly is wrong about that?

The nesting is too deep imho, but apart from that it looks ok. This looks more like a design problem, because there are lots of special cases, but the code style is ok.

I was also surprised to see these huge functions with multiple nested layers. Is it common for game development? Or it was just a quick hack on top of Quake engine?

Skimming through the academy source, some are fine, some are not.

For example, codemp/game/g_saga.c uses goto just fine. Three "goto failure" jump to the end of the function to handle the error case differently than a normal return. Not a very good example for proper goto use, but ok.

In contrast, codemp/cgame/cg_players.c should be refactored. It seems to be model loading code. If the loading fails, some gotos jump to the start of the function and using a flag variable a default model "kyle" is used instead of the arguments. If the default model is broken, this becomes an infinite loop. My style suggestion:

  if (loadModel(foo)) return;
  if (loadModel(default)) return;
  assert (false && "fallback/default model broken");

erikj12y ago

What's the most popular "proper" use of goto in the code? The implementations of finite state machines?

jhawthorn12y ago

I would guess error handing (freeing memory, closing fd's). A goto lets you avoid deeply nested if statements.
