When trying to sent my vechicle just up or down by setting the motor to <0, 0, 20>.

It goes up and foward/back, but wont go just up?

Well that's the weird thing

I just don't see why it's doing it, I mean <0,0,20> for linear motor seems kinda clear but it's still going up and foward/down and back?

Paramater wise I've played around with linear friction to see if that was doing it, but no joy.

I'll post extra code up later.

As Void says, there's not really enough information to go on as yet, but you might want to play with your vehicle's VEHICLE_ANGULAR_MOTOR_DIRECTION component (if it's a plane, that is). If you reduce the y vector of that, it should point the nose up, thus making you rise as you move forward.

hmm not letting me post my code i've had to spread across posts..

Ok heres more:


On control Up

curDir.z = 20;

llSetVehicleVectorParam( VEHICLE_LINEAR_FRICTION_TIMESCALE, <10, 10, 10>;);
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, .1);
llSetVehicleVectorParam(VEHICLE_LINEAR_MOTOR_DIRECTION, <0, 0, curDir.z>;);


Paramaters set on start

llSetVehicleType( VEHICLE_TYPE_AIRPLANE);

llSetVehicleFloatParam( VEHICLE_ANGULAR_FRICTION_TIMESCALE, 400);
llSetVehicleVectorParam( VEHICLE_LINEAR_FRICTION_TIMESCALE, <2, 10, 10>;);

llSetVehicleVectorParam( VEHICLE_LINEAR_MOTOR_DIRECTION, <0,0,0>;);
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_TIMESCALE, 1);
llSetVehicleFloatParam( VEHICLE_LINEAR_MOTOR_DECAY_TIMESCALE, 120);

llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_TIMESCALE, 1);
llSetVehicleFloatParam( VEHICLE_ANGULAR_MOTOR_DECAY_TIMESCALE, 900);

llSetVehicleFloatParam( VEHICLE_HOVER_HEIGHT, 0);
llSetVehicleFloatParam( VEHICLE_HOVER_EFFICIENCY, 0 );
llSetVehicleFloatParam( VEHICLE_HOVER_TIMESCALE, 50 );
llSetVehicleFloatParam( VEHICLE_BUOYANCY, 1 );

llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_EFFICIENCY, 1 );
llSetVehicleFloatParam( VEHICLE_LINEAR_DEFLECTION_TIMESCALE, 1 );

llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_EFFICIENCY, 1);
llSetVehicleFloatParam( VEHICLE_ANGULAR_DEFLECTION_TIMESCALE, 2);

llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_EFFICIENCY, 0.3);
llSetVehicleFloatParam( VEHICLE_VERTICAL_ATTRACTION_TIMESCALE , 8);

llSetVehicleFloatParam( VEHICLE_BANKING_EFFICIENCY, 0.9);
llSetVehicleFloatParam( VEHICLE_BANKING_MIX, .85);
llSetVehicleFloatParam( VEHICLE_BANKING_TIMESCALE, 0.3);


llRemoveVehicleFlags(

VEHICLE_FLAG_NO_DEFLECTION_UP |
VEHICLE_FLAG_HOVER_WATER_ONLY |
VEHICLE_FLAG_HOVER_TERRAIN_ONLY |
VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT |
VEHICLE_FLAG_HOVER_UP_ONLY |
VEHICLE_FLAG_LIMIT_MOTOR_UP

);

llSetVehicleFlags(

VEHICLE_FLAG_MOUSELOOK_BANK |
VEHICLE_FLAG_LIMIT_ROLL_ONLY

);

Angular

llSetVehicleVectorParam(VEHICLE_ANGULAR_MOTOR_DIRE CTION, < *.9, *.7, TIMES *.4>

The word "PI" is before the *. but for some reason the forum wont let me post that

you have two motors... the angular and the linear.....

and on top of that you have hover and buoyancy, so I wouldn't be suprised if wind is affecting it too....

Maybe it's deflection converting the up movement into forward movement?
