News and Updates on the Rigs of Rods truck simulator, based on an advanced soft-body physics engine.

Sunday, January 28, 2007


As you can see in the screenshots, I just added highly accurate hydrostatic/hydrodynamic physics in Rigs of Rods.

In the same philosophy that makes RoR so different, this is not just an approximated Archimedes law that was added, but a realtime local pressure gradient computation, that is able to accurately simulate any buoyant shape, in any position, and even with uneven water surface (waves!).

With this method, making boats is also quite easy, you just have to mark cab triangles as part of the hull and that's all! The water pressure gradient will be applied to the "wet" side of the triangles, and all these pressure forces will combine to make the boat float.

As always, the physics (the fun part!) is only 10% of the code, and I have yet to integrate boats to the gameplay (making nice dashboard, sounds, special effects, port infrastructure...).

Looks really, really cool Pricorde! You do amazing work man. Now we need a Dodge Ram diesel truck and a trailer to haul it out of the water with, along with a mesh of a boatramp!

Hi zipppy!! I started with RoR 1 year ago :)

It's a very nice game, and with some improvements on performance and graphics could rock anywhere! :P

Dear Mr. Pricorde:

I love your program. Thank you for making it.

Once upon a time, there was a police car (with a highly modified .truck file) that went as fast as it could. It hit something and then it started spinning like a breakdancer.
