Vehicle (boat) banking

I am playing with a inflatable boat vehicle. It works fairly well but banks on the turns. Inflatable boats don't usually bank in rl at lower speeds and was wondering what I have to set to have the vehicle turn without banking?

I've looked at the llSetVehicleFloatParam functions but they are a bit confusing.

Here are the settings:

llSetVehicleType(VEHICLE_TYPE_BOAT);
llSetVehicleFlags(VEHICLE_FLAG_HOVER_UP_ONLY | VEHICLE_FLAG_HOVER_WATER_ONLY);
// remove these flags
llRemoveVehicleFlags( VEHICLE_FLAG_HOVER_TERRAIN_ONLY
| VEHICLE_FLAG_LIMIT_ROLL_ONLY
| VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT);

// least for forward-back, most friction for up-down
llSetVehicleVectorParam( VEHICLE_LINEAR_FRICTION_TIMESCALE, <2, 3, 2> );

// uniform angular friction (setting it as a scalar rather than a vector)
llSetVehicleFloatParam( VEHICLE_ANGULAR_FRICTION_TIMESCALE, 2 );

// linear motor wins after about five seconds, decays after about a minute
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_TIMESCALE, 5 );
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, 10 );

// agular motor wins after four seconds, decays in same amount of time
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_TIMESCALE, 2 );
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE, 5 );

// hover / float
llSetVehicleFloatParam( VEHICLE_HOVER_HEIGHT, 0.3);
llSetVehicleFloatParam( VEHICLE_HOVER_EFFICIENCY,.5 );
llSetVehicleFloatParam( VEHICLE_HOVER_TIMESCALE, 2.0 );
llSetVehicleFloatParam( VEHICLE_BUOYANCY, 0.5 );

// halfway linear deflection with timescale of 3 seconds
llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_EFFICIENCY, 0.5 );
llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_TIMESCALE, 3 );

// angular deflection
llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_EFFICIENCY, 0.5 );
llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_TIMESCALE, 10 );

// somewhat bounscy vertical attractor
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY, 0.5 );
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_TIMESCALE, 2 );

// weak negative damped banking

llSetVehicleFloatParam(VEHICLE_BANKING_EFFICIENCY, 0.0);
llSetVehicleFloatParam(VEHICLE_BANKING_TIMESCALE, 1.0);
llSetVehicleFloatParam(VEHICLE_BANKING_MIX, 0.5);

// default rotation of local frame
llSetVehicleRotationParam( VEHICLE_REFERENCE_FRAME, <0, 0, 0, 1> );



Thanks Dina.

You might want to make VEHICLE_BANKING_TIMESCALE really high, like 1000.0. Otherwise, I BELIEVE the vehicle parameters look good. The next question is, what do you do when you get left/right (roll) control inputs? Do they apply rotation purely about the z-axis, or are they rolling about the x-axis like a script for a vehicle with baking does?
