glBSP

[chippo]

In another threadYou need to build gl nodes for the IWAD you are using. Simply download GLBSP (http://glbsp.sourceforge.net/), then drag and drop the IWAD onto the executable (Im assuming it will behave the same way in Linux). This will build the gl-nodes and allow you to play it with Legacy 2.

Since glBSP is needed to run the opengl version of legacy, and you do need to compile it, maybe it should be mentioned in docs/compiling.html.

I know this is the wrong forum, but does anyone know why it is that legacy-1 doesn't need gl nodes to run the WADs with opengl rendering?

So I downloaded the software (and noticed that the bastards advertise several doom ports, but not us :-( ), compiled painlessly and installed. I then ran it like so:
glbsp -warn Doom1.wad -o bsp-Doom1.wad
in my DOOMWADDIR, and the output looked promising:
Saving WAD as bsp-Doom1.wad
Total serious warnings: 0
Total minor warnings: 2
All levels were built successfully.

The two warnings:
Warning: Sector #7 is unclosed near (-220.0,-1920.0)
Warning: Subsector #376 near (-324.0,-1920.0) is not closed (1 gaps, 1 segs)
were both on E1M3, so I figured that they shouldn't be a problem if I only want to play the first level.

So then I ran the game with:
./Legacy -opengl -iwad bsp-Doom1.wad
and the menus were fine, but as the game should have started I got a black screen. TAB wouldn't produce any (visible) map, and firing didn't produce any sound. Musta crashed, and maybe even crashed X!!! Nope, hitting escape brings us the menus and OPTIONS seems to work and QUIT works, but READ THIS! just gives a blank screen.

OK, maybe something wrong with my id shareware Doom1.wad (though it seems to be fine in legacy-2 with software rendering and legacy-1 with opengl). Lemme try my Heretic1.wad (also id shareware).

The glbsp params and output was similar, but this time there were 14 similar warnings but all in the last level. So I similarly try to run it, and immediately I get my prompt back (i.e. no seg fault). Stderr.txt contains:

Then I try glbsp on my freedoom WAD, and the result was similar to one of the above (can't remember which, though, and I don't have that WAD anymore).

Then I assumed that maybe I was using the wrong parameters to glbsp, and ran 'glbsp -help'. I couldn't really understand much there. I read the man page (slight understanding) and the USAGE.txt, but I still can't really figure out what parameters I should use.

So while thinking about producing a bug report, I realised that I can't actually clearly state which exact version of which WAD I'm using (for other people in this forum to compare with). Then I remembered that smite-meister had once said: "I assume you're using freedoom-0.5". I wasn't, so I went and downloaded the file freedoom-iwad-0.5.zip.

I glbsp'ed as usual, and brought up legacy-2. It works! Viva, viva, viva! I now have legacy-2 working in fullscreen and opengl.

But my question is - is there anything (like different params to glbsp) that I can do to correctly create the gl nodes for the id shareware WADs?

TIA,

Strange, I was able to run Doom2, Heretic and Hexen in Legacy2 just by drag and dropping the Iwads onto the 2 node builders. I didn't need any extra variables..Then I decided, screw this I'm making a batch file. :)

I haven't tried the shareware version though..

I haven't tried the shareware version though..

Hmm. Wonder if that might be it... No success; no computer shop in Cape Town sells any doom software. :-(

Aha! Success. A friend has the original floppy discs of Doom1 and Doom2 and will sell them to me for R20 (about 3 USD).

Nope. Shareware wasn't to problem. Time to follow the ancient Jedi advice: "Use the source, Luke!".

Ha! There it is. In util/w_wad.cpp in the function InitMultipleFiles(), is the enlightement I was needing. So I run the following command:
glbsp -q Doom.wad -o Doom.gwa

Then I init legacy-2 with:
./Legacy -opengl -iwad Doom.wad
and away we go. After a bit more glbsp'ing I can now play the following in opengl on legacy-2:
- Doom1 commercial
- Doom2 commercial
- Heretic shareware
- Freedoom 0.5

I have trouble with my Hexen shareware. After starting the game I get the splash screen, but when I hit escape, I get returned to the command prompt. Stderr.txt contains:
open /dev/sequencer: No such file or directory
Fatal signal: Segmentation Fault (SDL Parachute Deployed)
(BTW, I've seen this /dev/sequencer error before on games that do work, so it's obviously not fatal.)

Hexen isn't supported by Legacy.

[smite-meister]

I know this is the wrong forum, but does anyone know why it is that legacy-1 doesn't need gl nodes to run the WADs with opengl rendering?

It has an entirely different OpenGL renderer.
glbsp does most of the work required for rendering a Doom map in OpenGL, and does it well, so we decided to make GL nodes a requirement.
As you noticed, the usual way of adding the GL nodes to an IWAD is to generate an additional file, originalfilename.gwa, which has only the nodes in it (so that the IWAD itself remains untouched).


So I downloaded the software (and noticed that the bastards advertise several doom ports, but not us :-( )

Quiet, Andrew might be listening :)

Hexen isn't supported by Legacy.

Oh yes it is. Almost fully. We're speaking about Legacy 2, remember?

[Planky]

Oops. .

[g6672D]

Has anyone got the latest version for testing? I'm getting mighty excited again. ;)

Of what? glBSP can be downloaded here:
http://glbsp.sourceforge.net/

[Aliotroph?]

I think he meant Legacy.

[g6672D]

LOL! LEGACY! LEGACY! Win32 version!

Only one poor bastard works on glBSP :)

I'll gladly add Legacy to the list. You could have sent me an email instead of moaning here.

[chippo]

Only one poor bastard works on glBSP :)

Only one person!? Wow! And it supports 6 different compilers across 4 operating systems. And (at least on linux) it compiles with -Wall, and not a single warning!

I'm terribly terribly sorry! I wasn't moaning; it was supposed to be a joke. I've had the exact problem before, in online forums (ae?) where I think I'm being funny, but nobody else sees it that way.

I can't speak for anyone else (on this forum), but I always imagined that we'd get all the advertising we wanted via the features that we put in. I didn't mind at all that glBSP's website didn't mention us. I also wouldn't mind if it did.

Anyways, sorry again. I'll try harder to keep my posts to technical stuff and try even harder to avoid humour, 'cos obviously I'm not good at it.

Cheers,

Well until Legacy2 came along the older Legacy versions would use the Zennode node builder, mainly for gl nodes. But yeah now days, Legacy2 needs glBSP.
Anyways chippo I thought it was funny :D

And yeah, we need a win32 compiled update ! plz*confused*

[Aliotroph?]

Yeah, it was kinda funny.

Aww shucks :).

My comment about having a moan was truly tongue-in-cheek, no need to apologise, definitely no offence taken!
