Error creating Hover Vehicles

Hi,

I'm new to Torque and have been playing with the vehicle datablocks. I had trouble getting a HoverVehicle object to be created.

I have something like that in my new script defaultShip.cs

datablock HoverVehicleData(BattleShip)
{
    mountable              = true;
    swappable              = false;
    mountPose[0]           = sitting;
    numMountPoints         = 1;

    category               = "Vehicles";
    shapeFile              = "art/shapes/Aircraft/bioship1(2.0).dts";
    computeCRC             = false;

    integration            = 4;
    collisionTol           = 0.1;
    contactTol             = 0.1;

    drag                   = 0.0;
    density                = 0.3; // Will float in water

    mass                   = 40;
    bodyFriction           = 0;
    bodyRestitution        = 0.5;

    mainThrustForce        = 1000;
    reverseThrustForce     = 700;
    strafeThrustForce      = 800;

    stabSpringConstant     = 100;
    stabDampingConstant    = 80;

    dragForce              = 10;

    vertFactor             = 1;
    floatingThrustFactor   = 1;

    turboFactor            = 1.5;

    stabLenMin             = 6.50;
    stabLenMax             = 7.25;

    normalForce            = 1000;
    restorativeForce       = 0;

    steeringForce          = 600;
    gyroDrag               = 40;

    rollForce              = 100;
    pitchForce             = 100;

    floatingGravMag        = 1;

    brakingForce           = 600;
    brakingActivationSpeed = 10;
};

I have edited the datablockExec.cs too

// Load up all datablocks.  This function is called when
// a server is constructed.

// Do the sounds first -- later scripts/datablocks may need them
exec("./audioProfiles.cs");

// Do the various effects next -- later scripts/datablocks may need them
exec("./particles.cs");

exec("./environment.cs");
exec("./triggers.cs");
exec("./lights.cs");

// Add a rigid example
exec("./rigidShape.cs");

exec("./health.cs");

// Load our supporting weapon datablocks
exec("./weapon.cs");

// Load the weapon datablocks
exec("./weapons/rocketLauncher.cs");

// Load the default player datablocks
exec("./player.cs");

// Load our other player datablocks
exec("./aiPlayer.cs");

// Load the vehicle datablocks
exec("./vehicles/defaultCar.cs");
exec("./vehicles/defaultShip.cs");

I know I need several functions like create, onAdd, to make run my game, but I have no idea of how and where put this functions.

I have been trying to fix it up, but everytime I "add" a BattleShip to my mission, it does nothing, and in the console appears:

"15: Register object failed for object (null) of class HoverVehicle"

All the paths are ok, so I am pretty sure this is not the problem.

Any idea?

Thank you very much.
