How to make things "float"

[Alexisfire]

Hi!
I'm actually working on a small project for my university, what i've to do is a little game where you can drive a floating car on a track(like F-zero game).
The question is...how should i implement the floating parameter?

Any idea? Actually i'm trying with the PlayerController Class...but i'm not sure, the rayCastVehicle also don't seem the right choise but maybe i'm wrong.

Any help would be really appreciate

Thanks!

Looks a lot like a raycast car with no tires.

Yes?
Great!
That's exactly what i was thinking to implement, thank you very much

Mmmm, something is not clear, without tires you mean, invisible or just "No tires"?

In the second case, what should i do?
If i try to add a suspension without connecting it to a tire, everythings work fine...but i've got a crash when i close the app.

Code: Select all

//Entity body e Node
   Auto* car;
   Entity* carEnt;
   OgreNewt::Body* carBody;
   SceneNode* parentNode;
   Node* node;

   //Create the main car body
   carEnt = mSceneMgr->createEntity(pName,cName+".mesh");
   parentNode = mSceneMgr->getRootSceneNode()->createChildSceneNode();
   parentNode->attachObject(carEnt);
   OgreNewt::ConvexCollisionPtr col(new OgreNewt::CollisionPrimitives::ConvexHull(world,carEnt,0));
   carBody = new OgreNewt::Body(world, col);
   //Base mass on the size of the object
   Real mass = 100.0f;
   //Calculate the inertia, based on box formula and mass
   Vector3 inertia, offset;
   col->calculateInertialMatrix(inertia,offset);
   
   carBody->attachNode(parentNode);
   carBody->setMassMatrix(mass,mass*inertia);
   carBody->setCenterOfMass(offset);
   carBody->setStandardForceCallback();
   carBody->setPositionOrientation(Vector3(0,50,0),Ogre::Quaternion::IDENTITY);
   car = new Auto(carBody);
   // for now just to get it going
   Ogre::Real friction = 0.1f;
   Ogre::Real suspensionLenght = 0.2f;
   Ogre::Real susSpring = 100.0f;
   Ogre::Real susShock = 0.0f;
   Real width = 0.38;
   Real radius = 0.33;
   car->AddSingleSuspensionTire(carBody,Vector3(-0.625456f, -0.296697f, -1.235474f),Real(10),radius,width,friction,suspensionLenght,susSpring, susShock);
   car->AddSingleSuspensionTire(carBody,Vector3( 0.625456f, -0.296697f, -1.235474f),Real(10),radius,width,friction,suspensionLenght,susSpring, susShock);
   car->AddSingleSuspensionTire(carBody,Vector3( 0.625456f, -0.296697f, 0.818093f),Real(10),radius,width,friction,suspensionLenght,susSpring, susShock);
   car->AddSingleSuspensionTire(carBody,Vector3(-0.625456f, -0.296697f, 0.818093f),Real(10),radius,width,friction,suspensionLenght,susSpring, susShock);

   return car;


*Edit*
Solved!
It seems that, even if you don't create tires, you still have to set they're number in the constructor, now everything work fine!!
Thank you again!
