Stunt Rally 2.6 and Irrlamb 0.2

Stunt Rally 2.6 has been released, with new features including pacenotes (i.e. corner speed/severity hints) and a rewritten sound system with reverberation (changelog).

Stunt Rally is a sandbox racing game with a huge number of tracks (172 in 2.6) and lots of cars. It was originally forked from VDrift and features Ogre3D as a graphics engine instead of the custom (and less sophisticated) graphics engine in VDrift.

A video is worth a thousand pictures and a picture a thousand words so, instead of me writing a million of those, I invite you to check out the gameplay in the video that accompanied the release:


Also recently updated is Irrlamb. Those with incredibly good memories will recall this physics-based game originally appearing many years ago. I originally wrote about Irrlamb over 8 years ago on Free Gamer, and the previous release (0.1.1) is over 5 years old if I'm not mistaken (it is hard to check since things have moved on since then i.e. Google Code where its development was originally hosted).

This release adds new graphical capabilities, new levels, gamepad support and various fixes - see the announcement for more details.

I'll also write a really lengthy... wait a minute! Let's link a video instead. ;)

The joys of programming - hours spent scratching one's head whilst trying to figure out why the seemingly correct code does not produce correct results.

Hi, Charlie here. I used to post often.

Where was I? Ah, yes, this nugget of brain fudgery from the VDrift forums posted by NaN:

So I've spent some time today try to figure out why cars are still flying off in random directions when hitting curbs sometimes.

It turns out it is a bug in Bullet, to be more specific in the SIMD_DEGS_PER_RAD macro.

Code:

#define SIMD_PI           btScalar(3.1415926535897932384626433832795029)
#define SIMD_2_PI         btScalar(2.0) * SIMD_PI
#define SIMD_HALF_PI      (SIMD_PI * btScalar(0.5))
#define SIMD_RADS_PER_DEG (SIMD_2_PI / btScalar(360.0))
#define SIMD_DEGS_PER_RAD  (btScalar(360.0) / SIMD_2_PI)

The first one to spot it gets a virtual cookie.

For the answer visit the thread, I won't spoil it here. Instead, I'll post a screenshot, also sourced from said forums and taken by Stunt Rally author CrystalH.

 


For those who don't know, Stunt Rally is a friendly fork of VDrift.

May the source be with you

I'm a big advocate of the phrase, "Release Early, Release Often." I think it is by far the best way to keep or gain community interest in a project.

Of course, that simple phrase doesn't quite sum up what you actually must do - simply uploading a release and announcing it on your mailing list is unlikely to attract interest. For example, who knew about Lincity-NG 2.9beta in lieu of the intended Lincity-NG 3.0?

Lincity-NG is in a bit of a mini-crisis. A victim of the shutdown of the Berlios developer services, all the web material is in a bit of a mess. Its home page is now on fedorahosted.org but still links back to the defunct Berlios page. There are entries on Google Code and Github that are up to date with the source, as well as an imported Sourceforge project* which is the only place you can currently find the beta, however all are unofficial / back up for now.

(* Not to be confused with this redundant redundant project)

Another game project which suffered was Battles of Antargis. It has re-emerged on Github and development seems to have resumed with C++ replacing the Ruby bits which previously encumbered the game. For a web presence, you have to use the Internet archive for its old Berlios page or external sites e.g. the LGBD entry or on Libregamewiki.

It's not just Berlios that throws a spanner in people's works. Sourceforge has setback the oft-setback Extreme Tux Racer by closing down their hosted apps. The main communication medium was phpBB but now it is completely gone. They did manage to get an updated 0.6.0 release online before this, at least.

Since there doesn't appear to be any project communication channel for ETR, I have contacted them suggesting a FreeGameDev forum.

Speaking of FGD forums, there's plenty of activity amongst the projects there. Stunt Rally continues to gain more strings to its bow. Sci-fi hovercrafts! That ought to be interesting. Despite being one of the prettiest open source games and incredibly put together almost by one person, CryHam - well, not quite; it took VDrift's physics and Ogre3D's jazz - the project doesn't seem to get the attention it deserves.

Sci-fi overcrafts now in Stunty Rally
You can browse the tracks online. Check out this fun looking track with pyramids and chasms galore.

Another project gaining momentum is OpenDungeons. It's had its ups and downs, but seems to have gotten its footing now with regular test releases and several active contributors. The new website is coming along, but more importantly so is the game as especially Yohann Ferreira aka Bertram (of Valyria Tear fame) has come in and steadied the ship. I look forward to seeing creatures like this golem trudging dark, damp and dangerous dungeon corridors.

Of course the reality of open source game development is that it is not an overnight job. It takes years of perseverance to realise the goals of many projects. Over the course of that time, occasionally the rug may get pulled from under you. You just have to be prepared to dust yourself off, get up, and keep going.

Or you could just call it quits.
