[Gtkradiant] Gtkradiant Digest, Vol 50, Issue 2

Fri Oct 24 08:43:12 CDT 2008

Hi All,

Could anyone please let me know if gtk radiant supports editing for Quake4 under linux ?? and if it does so, can you please point me to a tutorial/guide about how to di it ??

I would like to set this up for our animation students, so they can build their own levels, import animations from Maya etc, but we run on Fedora.

Thank you for your replies..

Did you know Quake1/2/3/Unreal/etc have 7.1bit fixed point lightmaps?  (I.E. their range is 0-2 mapped to 0-255 byte values)

Not much in the way of HDR, but it's something.

Regarding collision detection, you might be interested in model_brush.c in the DarkPlaces source code (glquake-derived engine that powers the standalone game Nexuiz and several other projects, besides
playing Quake1).
http://svn.icculus.org/twilight/trunk/darkplaces/model_brush.c?view=markup - do a search for TraceBox and you will find the Q1BSP/HLBSP and Q3BSP implementations of collision detection.

http://svn.icculus.org/twilight/trunk/darkplaces/collision.c?view=markup - this file contains all my brush collision code.  (otherwise known as qhull, or "convex solid")

You can find more information about the engine at http://icculus.org/twilight/darkplaces/

Looks like you tried to load gfx.wad which contains only qpic images (hud imagery), you need the quake1.wad from the Q1Pack instead (which contains picmip images - mipmapped textures for maps).

Well that clearly needs to be fixed.

I don't know GTK+ at all, but if you wish to contribute a patch feel free :)

Thanks, I'll have a detailed look. I already knew about your engine..
i didn't know it supports so many bsp formats though :)

Where can I find this quake1.wad? I searched here:
https://zerowing.idsoftware.com/svn/radiant.gamepacks/Q1Pack/trunk/
but it is not there... Perhaps I can generate the wad from the bsp
files... but that would be pointless if the file already exists
somewhere.

I'd like to make this patch, but I don't know the procedure... I guess
I have to checkout the latest revision, and fix the code, but then
what do I do?

The problem arised because GTK+ is probably no longer using the
'page-size' property of GtkAdjustment (not sure tho), and now it's
issuing a warning for each Adjustment it finds with a non-zero page
size. I guess GtkRadiant will just have to comply :P

Ok, I fixed it, now how do I generate the patch?

Ok, I figured it out. Ran 'svn patch > gtkadjustment.patch'.

Hope attachments work.
