Getting started with the GTK Radiant source code

Hi, I thought it would be a nice boost of my projects if I
simply modifier the GTK radiant for my needs instead of
developing my own editor (did this for some time), I worked
with the q3 radiant source a few years ago


Now back to topic, I am a bit lost with the source since I
can't find any documentations

There are quite a few libraries you use, like the scenelib
....


I tried to figure out some basic mechanisms such as saving
files, from my understanding you have a visitor which is
used to traverse the scenegraph in order to find the
appropriate node and dump them to a txt stream.

The whole map output/input is placed into a plugin

My basic aims are
-  add another input/output plugin for a customized
fileformat
-  I realized the when creating simple patches the afore
created brush is not remove as I am used to in q3radiant,
that also one thing I want to change
- make the focus of the cam windows drag&drop as its
with the orthogonal views, no second right mouse click to
get out of free cam more

-  add a mechanism to place decals into the walls that are
rendered as an additional texture layer



Are there some informations or is the a wiki or something
where I could find some information about the whole frame of
the source code ?


thx in advance

Unfortunatly there isn't any documentation. This has always
been the major
drawback or weak point of gtkradiant.
There is some documentation in the header files of the most
important libs,
but thats not much. The darkmod people created a wiki which
explains
some of the modules of gtkr, however, since darkradiant is a
fork and
the devs from darkmod start to replace significant parts or
gtkr
some infos in the wiki do not apply to gtkradiant anymore.
Most informative should be this
http://www.thirdfilms.com/darkwiki/ind
ex.php?title=DarkRadiant_scene_graph
and this page
http://www.thirdfilms.com/darkwiki/i
ndex.php?title=DarkRadiant_shader_system
the other pages seem to be too darkradiant specific to be of
use.

> -  add another input/output plugin for a customized

Is that really what you want?
I guess you just need output in a custom format. I use gtkr
for
a project of mine and I wrote a little plugin that cruises
through the
scenegraph and dumps everything in a custom format.
This final export is done when I want to export the map into
my game.
During normal mapping I just use the Doom3 mapformat.
The reason I'm doing it this way is that a plugin is _much_
easier to write
for GtkR then a new mapformat.

My personal expierence is, that the fastest way to get
familiar with gtkr,
is to debug it. Place a breakpoint in a sourcepart in which
you are interested
and analyse the callstack which took you there.

Hi, thx for the information

The reason I want to implement a new map format is primarily
because I need to, some additions I want to make require me
to either change the existing q3 map format, so I could as
well just grab the q3 .map format plugin and adjust it to my
needs and maybe get it to work as the standard map format.

I ll also need an enhancement of the current shader
definitions, so there s really a lot of work to do

Hi, I am implementing my own map format for my engine at the
moment.
One thing I notices or might have missed is how do you get
the u,v scaling of the shaders for patches?

I have searched the code a little and you don t seem save
any scaling values is that correct?

I agree with you, hosting a third party forum is not an
option, I am all for an official forum, we could post
tutorials and introductions there, you will have a nice
overview of the structure.

P.S.: can t we move the export & import Tokens functions
out into the modules? otherwise the modules don t make much
sense at all
