Vehicle Joint use

Postby frankk » Thu Oct 09, 2008 3:09 pm

Hi,

We chose to use the Newton Physics engine in our final school project. The game is a car game and we use DirectX 9. I converted all the calls to OpenGL in order to integrate Newton with DX to implement a simple sandbox with a few shapes that collide. However, we're having a really hard time to simulate a car using the special car joint. I have read and re-read the sample 9 in the SDK called Simple Vehicle (which is not simple at all) and my vehicle does not correctly worked. After almost a week, I thought I had done something cuz my wheels stood at the right place and turned correctly with the steering. So, I tried to shoot some spheres at the car to see if it collided correctly and BOUM ! the wheels and the car body went in all directions. What I'm not sure about is the rigid body (is it the body or a bounding box to the whole vehicle?) and all the matrices involved and how to setup the joint correctly cuz it does not work. I searched down the net for a couple of hours but didn't find anything about it since the doc is really absent.

Could you help me please ? (and prove me i have made the good choice of choosing newton instead of another physics engine for our project ?)

Sounds like you're using 1.53. PM Julio on here and ask him to send you the 2.0 beta. It's much simpler to make a vehicle with it, and it is overall much faster and more robust than 1.53.

I'm in the same situation. I'm working with the sample 9 of NewtonSDK 1.53 but I have problems.
I searched some examples/samples in the NewtonSDK 2.0, but I could only find the RayCastVehicle sample and looks way more difficult.
And regarding CustomMultiBodyVehicle, there's no example on how to drive the vehicle or similar, so...
I just need the easiest implementation of a vehicle!
