Description

Constant: integer VEHICLE_TYPE_BOAT = 3;

The integer constant VEHICLE_TYPE_BOAT has the value 3

Hovers over water with lots of friction and some anglar deflection.

Effects

Setting the vehicle type to boat enables the vehicle system and additionally has the same effect of executing the following:

// least for forward-back, most friction for up-down
llSetVehicleVectorParam( VEHICLE_LINEAR_FRICTION_TIMESCALE, <10, 3, 2> );
// uniform angular friction (setting it as a scalar rather than a vector)
llSetVehicleFloatParam( VEHICLE_ANGULAR_FRICTION_TIMESCALE, 10 );
// linear motor wins after about five seconds, decays after about a minute
llSetVehicleVectorParam( VEHICLE_LINEAR_MOTOR_DIRECTION, <0, 0, 0> );
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_TIMESCALE, 5 );
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, 60 );
// agular motor wins after four seconds, decays in same amount of time
llSetVehicleVectorParam( VEHICLE_ANGULAR_MOTOR_DIRECTION, <0, 0, 0> );
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_TIMESCALE, 4 );
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE, 4 );
// hover
llSetVehicleFloatParam( VEHICLE_HOVER_HEIGHT, 0 );
llSetVehicleFloatParam( VEHICLE_HOVER_EFFICIENCY, 0.5 );
llSetVehicleFloatParam( VEHICLE_HOVER_TIMESCALE, 2.0 );
llSetVehicleFloatParam( VEHICLE_BUOYANCY, 1 );
// 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, 5 );
// somewhat bounscy vertical attractor
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY, 0.5 );
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_TIMESCALE, 5 );
// weak negative damped banking
llSetVehicleFloatParam( VEHICLE_BANKING_EFFICIENCY, -0.3 );
llSetVehicleFloatParam( VEHICLE_BANKING_MIX, 0.8 );
llSetVehicleFloatParam( VEHICLE_BANKING_TIMESCALE, 1 );
// default rotation of local frame
llSetVehicleRotationParam( VEHICLE_REFERENCE_FRAME, <0, 0, 0, 1> );
// remove these flags
llRemoveVehicleFlags( VEHICLE_FLAG_HOVER_TERRAIN_ONLY
    | VEHICLE_FLAG_LIMIT_ROLL_ONLY
    | VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT);
// set these flags
llSetVehicleFlags( VEHICLE_FLAG_NO_DEFLECTION_UP
    | VEHICLE_FLAG_HOVER_WATER_ONLY
    | VEHICLE_FLAG_HOVER_UP_ONLY
    | VEHICLE_FLAG_LIMIT_MOTOR_UP );
