[ODE] Car Simulation and dWorldStep

[Jon Watte]

For a sample of a wheeled vehicle (jeep-like) using ODE, try 
the mywheeledvehicle.cpp file in the carworld demo:
http://www.mindcontrol.org/~hplus/carworld/

For a description of how to run a physics engine in the face 
of varying frame rates, have a look at:
http://www.mindcontrol.org/~hplus/graphics/game_loop.html
Or just look at the content.cpp file from the carworld demo, 
although that doesn't do position interpolation between 
physics frames, so any FPS greater than 100 won't be noticed.

Cheers,

AHOY!

I made a small car simulation test... but is not real :-/
I made the car with box and spheres, but the result is like "test_crash" 
sample from ODE, not a real suspension system, not a real engine system...

There any good car sample with source to try to find where is wrong???
If I made a simulation like Nix is very good to know what I need to do 
and learn more about ODE :D

(I'll upload what I made later, my FTP is offline :-/)

And about dWorldStep, I made it: dWorldStep ( ODE_World, FPSMove(0.05f ) );
FPSMove = (x / fps) * 60

Ok, I made it to try to sincronize the ODE simulation with FPS, but work 
and don't work... some times work everything right other times many 
errors, how can I sincronize the simulation with FPS?


Thx
