Ridiculous airbus hosting a gmod ttt convention.
Getting Started
Working with hl2, gmod, steam, and windows.
Environment Requirements
compile bsp:
- Windows
- Steam
- Garrysmod
- Counter Strike: Source
- git-bash
- gnu make (winmake)
- python3
create texture:
- gimp or other
- vtfedit
- vim or texteditor
create a static model:
- blender
- blender source tools (smd export)
Build Environment Setup Notes
- the project checkout was authored in a prefix with no spaces
- a python virtual environment is used to provide the pyvmf library to the
build toolchain. this library is based entirely on the stdlib with no
external dependencies
.. code::
# from project root (ttt_terrorcon/)
python3 -m venv env
./env/scripts/python -m pip install -e .
- the normal make target recommended is 'all'
.. code::
make all
- useful make targets
.. code::
# build the bsp in fast mode and skip all hl2.exe compilation steps,
# run the game on the map as if it were a stand-alone gmod addon
# this is helpful for testing changes to the vmf file
make -B
# simmilar as above with full hdr lightin (and build cube maps)
make -B ttt_terrorcon_v2_hdr_final.{cubehdr,game-mount}
- building nav appears to always remake, probably this is a cyclic-issue where
generating the .nav file alters the .bsp file and therefore invalidates the
.nav file in gnu make
- is building the nav fails, a crude 15-min itmeout is used to determine the
failure, more sophisticated ipc is desired
Engine Setup Notes
- css needs to be mounted in garrysmod/cfg/mount.cfg
- use the hammer bin in the normal non-beta gmod install Garrysmod/bin/hammer.exe
- configure hammer, add the ttt cfg garrysmod/gamemodes/terrortown.fgd
- gimp created jpeg's are incompatible with gmpublish, be sure to open and save
with mspaint to make them compatible
Modeling Setup Notes
- use the decimate modifier + triangulate modifier as the last step of all ref
(visual) models, hl2.exe does not handle polygons correctly, all pologons
must be triangualted.
- be sure to convex-hull each seperate mesh object that composites a phys
(collision) model and then triangulate.
- it can be helpful to name the blender materials to match the hl2.exe material
name (this is mandatory) and then load the materials vtfedit import format
(normally tga) as the blender materials albedo/base color's image texture.
this helps preview uv maps (or edit them with texture paint) in blender.
Settle Physics Notes
- vfm documents must be located in garrysmod/mapsrc (not mapsssrc)
- bsp documents must have the same basename as the vmf and be located in
- hammer (garrysmod/bin/hammer.exe) must be open with the vmf document before
map_edit console command is used.
the make task '%52.setphys' will automatically setup and settle the physics,
but saving the map with hammer is left as a manual step, a n interactive rm
prompt is left in the make file so that after the map is saved, the operator
can confirm the removal of the working file by entering 'y' and '<enter>', the
remainder of the build will resume normally.
Custom Tools
The following tools were created to work around limitations of hl2, gmod,
steam, and windows.
.. list-table::
:header-rows: 1
- - relpath
- description
- - contrib/
- a collection of non-essential programs which aid developers
- - contrib/blender-render-model
- automate the blender process: blend -> SMD -> MDL
- - contrib/bspzip-all
- automate the bsppack process
- - contrib/bspzip-lint
- report issues with the bzppack database
- - contrib/epoll-then
- poll a file, when the document matches a reference, run a command
- - contrib/gen-bspzip-addlist
- generate a bspzip-addlist file from a vmf file
- - contrib/gma-install-bspzip-addlist
- convert standard bsp zip to gma content where content is illigal in
- - contrib/gmad-tar
- create a gma file and matching tar file, gma format isn't portable
- - contrib/j2
- format a string using jinja2 (named replacement), fancier than
- - contrib/mount
- garrysmod/cfg/mount.cfg cli interface
- - contrib/
- generate vmf fragments
- - contrib/
- generate vmf fragments
- - contrib/
- generate vmf fragments
- - contrib/shlex
- translate a windows-managled argv into a heuristically
reconstructed argv and escape correctly for windows
- - contrib/supervise-v
- supervise vbins, report issues, and fail if the input-output file
remains unchanged
- - contrib/vmt-lint
- report issues with a vmf database
- - contrib/winpgrep
- poor-mans pgrep for windows, note under high load, "tasklist" is
prohibitivy slow

modeling notes
[obsolete] before a reference 1m vmf cube and reference 1m blender/qc cube were
compared, this value was used. Presently the scale value "52.49" is
one blender unit == 1 meter:
# *.qc
$scale = 19.680119
when trying to solve complex logic programs in hammer, lay out your problem in 2d with nodes like a spreadsheet, I find this helpful.
