It seems all of my vehicles like to bounce, this means i can't actually drive them because they're bouncing all the time
void CVehicle::addWheel(Simufarm::WheelParams& params)
{
NxOgre::WheelParams wp;
wp.setToDefault();
wp.setToNormal();
wp.mass = 50;
wp.suspension_damper = 50;
//wp.suspension_spring = 50;
NxOgre::Wheel* mTempWheel = static_cast<NxOgre::Wheel*>(mPhysBody->addShape(new NxOgre::WheelShape(params.Radius,"Offset: "+Ogre::StringConverter::toString(params.Pos),wp)));
mTempWheel->addMesh(params.Model);
mWheelSet->mWheels.insert(mTempWheel);
//Setup Steering and Driving Wheels
if(params.Powered)
mWheelSet->Drive.insert(mTempWheel);
if(params.Steering)
mWheelSet->Steering.insert(mTempWheel);
}
And creation of PhysX:
void CGame::createPhysicsWorld()
{
mPhysWorld = new NxOgre::World("log: txt");
//PhysX Debugger
mPhysWorld->getPhysXDriver()->createDebuggerConnection();
mPhysScene = mPhysWorld->createScene("SufPhysScene",mSceneMgr,"gravity: yes");
mPhysScene->setGravity(Ogre::Vector3(0,-9,0));
}

If the bouncing is due to the suspension, play around with the spring and/or damper rates until you find the figures that work for you.

I Still get the same behavior with the default settings

The default suspension settings may not work well with the mass of your vehicle, have you tried changing them?

The mass is 100, and My friend has tried to play around with them with no luck

Mass is to low for one thing. 100 Kilograms probably weighs less than you.

Currently in my game I'm using 1400 for the mass of my car, a spring rate of 15000 and a damper of 400.

It changes the way they bounce, but they still bounce
NxOgre::WheelParams wp;
wp.setToDefault();
wp.setToNormal();
//wp.mass = 50;
wp.suspension_damper = 400;
wp.suspension_spring = 15000;
I'm using 0.9 if it matters.

And the mass of the car is 1500-2500?

1400 Yes

Then keep increasing the mass of the actor.

That's one really heavy vehicle of 154.3 tons you have there. I'm sure altering the suspension or springs will do it.

danharibo, try these values:

BTW are you using the earth gravity ?
There about (-9)
Could this have something to do with the fact that the 1m cube is more like a 1/2foot cube?
wait! are you using density instead of mass ?

No, I'm using "mass: 140000"
