About Car simulation

I have created a car with four wheels. Two were JointHinge2 type(for motor), two were JointBall(for support only).

I will set the velocity of two JointHinge2 wheels directly to control the car. What’s more, I would like the velocity immediately changed to the value I set, so I set the dParamFMax to Max of float.

However, When I implement it, the car will bounce when velocity suddenly has a large change. What can I do to avoid this bounce and have a smooth car movement?

Have you looked at the Car Demo? That seems to work well…

The car demo seems to work by adding force, but In my simulation, I would like to set the wheel speed directly, so the change might be more drastic…

This is unrealistic, but If you want the car to start right a way you could add also some speed to the car directly.

I don’t think the [Odejava] car demo does use forces, I used it as a base too.

Once it’s working, it’s a good idea to move to a more realistic simulation, and I think the recommended option is an AMotor. I havn’t changed yet though.

Will.
