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 developm...

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 thr...
