Description

Constant: integer VEHICLE_TYPE_CAR = 2;

The integer constant VEHICLE_TYPE_CAR has the value 2

Another vehicle that bounces along the ground but needs the motors to be driven from external controls or timer events.

Effects

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

// most friction for left-right, least for up-down
llSetVehicleVectorParam( VEHICLE_LINEAR_FRICTION_TIMESCALE, <100, 2, 1000> );
// no angular friction
llSetVehicleVectorParam( VEHICLE_ANGULAR_FRICTION_TIMESCALE, <1000, 1000, 1000> );
// linear motor wins after about a second, decays after about a minute
llSetVehicleVectorParam( VEHICLE_LINEAR_MOTOR_DIRECTION, <0, 0, 0> );
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_TIMESCALE, 1 );
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, 60 );
// agular motor wins after a second, decays in less time than that
llSetVehicleVectorParam( VEHICLE_ANGULAR_MOTOR_DIRECTION, <0, 0, 0> );
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_TIMESCALE, 1 );
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE, 0.8 );
// no hover
llSetVehicleFloatParam( VEHICLE_HOVER_HEIGHT, 0 );
llSetVehicleFloatParam( VEHICLE_HOVER_EFFICIENCY, 0 );
llSetVehicleFloatParam( VEHICLE_HOVER_TIMESCALE, 1000 );
llSetVehicleFloatParam( VEHICLE_BUOYANCY, 0 );
// maximum linear deflection with timescale of 2 seconds
llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_EFFICIENCY, 1 );
llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_TIMESCALE, 2 );
// no angular deflection
llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_EFFICIENCY, 0 );
llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_TIMESCALE, 10 );
// critically damped vertical attractor
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY, 1 );
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_TIMESCALE, 10 );
// weak negative critically damped banking
llSetVehicleFloatParam( VEHICLE_BANKING_EFFICIENCY, -0.2 );
llSetVehicleFloatParam( VEHICLE_BANKING_MIX, 1 );
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_WATER_ONLY
    | VEHICLE_FLAG_HOVER_TERRAIN_ONLY
    | VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT);
// set these flags
llSetVehicleFlags( VEHICLE_FLAG_NO_DEFLECTION_UP
    | VEHICLE_FLAG_LIMIT_ROLL_ONLY
    | VEHICLE_FLAG_HOVER_UP_ONLY
    | VEHICLE_FLAG_LIMIT_MOTOR_UP );
