Open-source head-tracking

Wednesday, October 31st, 2012

So unless you are living under a rock, you have probably heard about the new VR-google craze soon to hit every hard-core gamers cave (e.g. Occulus Rift). We talked about the FOSS engine getting Occulus support before, and now that id software promised to release the Doom3 BFG Edition source code too, it looks like VR in FOSS games will become quite common soon.

However, hidden in the (flight-)sim genre another quite nice system has been developed, using only a (sufficient frames per second) webcam:

The video is shot with FlightGear, everyones favorite open-source flight-sim. More details how to get it running with FlightGear can be found here, the system itself is not FlightGear specific though.

The source-code can be found here to be adapted to to your game (any 3D game that doesn’t require too fast head-movement is basically suitable). The face-tracking is based on OpenCV, which will take some juice from your idling quad-core CPUs ;)

Less resource demanding are infrared LED tracker version, which do not need to follow a face and also work rather nicely in a dark room. For those, some propitiatory solutions have been available for some time, but you can also find Linux compatible open-source code for such a system here (instructions for FlightGear here).

Personally I was always to lazy to build myself a proper 3 dot LED cap, so I think the face tracking solutions are more convenient. If you are into non-FOSS games on the Windows platform, I can thus also recommend the partial open-source FaceTrackNoIR software, which supports quite a few really nice flight-sims, racing games and even FPS.

Force: Leashed – GPL First-Person Gravity Not-Like-Portal

Monday, October 29th, 2012

Force: Leashed is a free first person gravity fiddler. To advance, you need to guide rockets to their targets using spherical potential fields. And no, it’s not like Portal. That much.

Force: Leashed was started as one of the 2012 7DFPS prototypes. It is based on GPL-licensed Darkplaces which for example also powers Xonotic.

Force: Leashed is available for free download for Linux, Mac OS X and Windows from its website.

The art asset license status is unknown. Watch this tweet for further information.

Scavenger: Atmospheric Open Source 2D Space Exploration

Friday, October 26th, 2012
Image: Scavenger in-game credits

Scavenger is a simple space exploration game set in a large debris field, created by Fiona Burrows in December 2009.

It is polished, very atmospheric and expresses a subtle sense of humor inside item/object names.

Scavenger was voted 2nd place in the “overall” category at Ludum Dare 16 (48 hour dev jam). It recently was released in a github repository under MIT license (both code and art!).

The code is written in Python and runs on Linux, Mac OS X and Windows.

On her blog, Fiona writes about her development process:

  1. Pick a simple idea and roll with it.
  2. Never leave an unfinished feature.
  3. If anything can be polished then do it – If an animation can be added to something then do it, if a small particle effect can be added here then do it.
  4. Don’t stress over running out of time. When it doubt, pretend this was the plan all along.

Aleona’s Tales (Stratagus game)

Monday, October 15th, 2012
Small retro-style quick news today, so that you don’t hear the crickets here on FreeGamer:

There is a new game available for the FOSS classic engine Stratagus (read up on the history of it here). It is called Aleona’s Tales:

Looks very familiar, right? Yes Grandpa!

You can download it here (only windows builds) and discuss with its creator on the Stratagus forums. Graphics are sadly a mix of various Free and non-Free licenses… but at least you get it for freeeee…

Major Unvanquished update (Alpha 8)

Monday, October 8th, 2012

UPDATE: Here is a nice video of the (Note: Alpha) gameplay:

Yesterday (following their monthly release cycle) a new alpha from Unvanqished was released. For those with bad short term memory: Unvanquished is trying to revitalize the RTS/FPS hybrid Tremulous.

New Unvanquished human player and weapon model

Besides the changes already mentioned previously, they have also replaced some more weapon models and now also have a really nice new webpage!

Still lots of things to do… but big thumbs up for the progress so far!

git clone https://github.com/Bertram25/ValyriaTear.git
cd ValyriaTear/
cmake .

./src/valyriatear

Valyria Tear is easy to compile with CMake and features about 30 to 60 minutes of gameplay so far.

Twine: interactive stories builder

Monday, September 24th, 2012

Twine is a tool for creating non-linear stories that can be played in HTML. Here are some examples. It’s available under GPL and runs on Linux, Mac OS X and Windows.

There’s also a tutorial available by a game designer I follow.

Beginning this Thursday, there will be a one-week-long Virtual Game Jam in a community of gamers that are feminist, queer, disabled, people of color, transgender, poor, gay, lesbian, and others who belong to marginalized groups, as well as allies. They have an IRC channel.

I will give this tool a try at the next Berlin 8-hour Jam.

Torque 3D engine liberated

Friday, September 21st, 2012

The people behind the always very indi friendly and well renowned commercial Torque 3D engine announced a fews weeks ago that they will release the quite fully featured engine and tool-box under the very liberal and FOSS MIT license.


Well, and today they made an release announcement and opened up their repositories!

Some of you might remember the engine from the good old days of Tribes 2, but as you can see it has advanced quite a bit since then. Sadly it also lost its Linux and MacOS ports along the way, which is something the creators hope to have restored more quickly in the open-source version. Other show-stoppers on non-Windows platforms are a few remaining to be removed propitiatory qt-lib in the editor framework and so on. So if you think you can help them with either or those problems, have a look at their git repo here (click on “zip” to download you local copy).

Hmm… what does that mean for the FOSS gamer (besides some commercial game ports to Linux probably soon)? Well Torque is a really good tool-set to create new FOSS games, and they really tried to keep the entry barrier low, which is something that sadly can not be said for most other FOSS 3D engines. So in the longer run there might be some cool new games utilizing it. But for now I hope to see a fully FOSS version of this little gem soon ;)

As always… we will keep you updated with our irregular posts ;)

Shorts: FreeOrion 0.4.1 and Xonotic Vehicle Gameplay

FreeOrion

video: FreeOrion testplay (best viewed at 720p HD)

FreeOrion 0.4.1 has been released a month ago. There still is no manual ship combat mode and there is a certain sluggishness regarding GUI responsiveness but the beautiful audio and graphics and consistent writing are definitely worth a try.

You can check out a preview of current 3d ship combat tech demo in this video (7m30s in).

Xonotic

Unsealed Trial 2 - Xonotic1233544-00
image: Sniping a Hovercraft on Unsealed Trial 2 in Xonotic (more screens)

I have been playing Xonotic on the [MoN] Vehicle Gameplay server and quite enjoying it lately. Just recently, a first version of Unsealed Trial 2 (screenshots) has been released there.

Some helpful vote commands:
vcall timelimit 600 (for when the time is draining too quickly)
vcall gotomap unseal (for when you realize that Unsealed Trial is the only playable map ;) )

If you’d like to record your own videos, all you need to know is on Xonotic’s Democapture wiki page.
