(Added an implmentation for KShip which should work out-of-the-box, and a sample vehicle (FlyingDog) based on it.)

'''LiKeMiKeS:''' I've tried many times compiling this KShip script and have ended up with an error for the ShipState 'struct' & 'var' references obscuring each other and haven't been able to figure out a clean fix so it will compile - without creating another unneeded var instance or reference. I'm still learning the nuances of uscript, so it's difficult to debug atm.

'''Brold9999:''' I tried the above code long ago and it didn't seem to work. I have gotten a lot of questions on my mod, UT Space Battle, as to how I implemented the vehicles. I did not use a Karma or PhysX based approach but that is what most of the people who have asked me about this seem to be looking for. I have taken the code above and hammered away at it until it works. I ripped out many unnecessary sections (such as afterburner) which only cluttered the salient concepts of implementing a 6DOF vehicle. The new version should compile and work out-of-the-box and has (mostly) working netcode. Some tweaks are still necessary to make a vehicle suitable for a mod but this one does the basics that seem to trip most people up when they try to implement a 6DOF vehicle. KShip is the base 6DOF vehicle, FlyingDog is a butchered Bulldog which is based on KShip. Code follows:

Well this is basically my code for a space ship, thanks a lot to Daid for lending me his replication code (which turned out to come from KCar but i thank him non the less, great guy he is :D)

I currently use a different, more client oriented replication system, but this one here is a lot better, i havent incorporated my ship to it yet because i have some other problems that come with it that i have to solve, but since the "core" ship here is simple, ill use the better replication for you guys :)

(Btw i deal with all the entering/leaving of the vehicle in a parent class, this is really irrelevant to physics and is easy to do, so i left it out just so there will be less and easier to read code)

var float			Roll, CThrust, TempThrust, OldThrust; 
// Throttle and Steering are already declared in KVehicle, so all we need is roll, CThrust, TempThrust, OldThrust will be explained soon
// BTW note that i use Throttle for Pitch alteration because it is already bound by other vehicles to the forward/backward key
// ok i have also incorporated a system that allows for various thrust managments, 
//if you simply want to move forward full speed only while you press the the thrust button, you would use TempThrust. 
//when you release the thrust button you though you should always set TempThrust to -1
// if you want to have a constant speed, assign it to CThrust, so every time you release the thrust button (the one that changes TempThrust) 
// you would automatically start going at that speed (good for stuff like dogifghting and matching speeds)
// and lastly i added an afterburner effect, ill include it here for you guys to see although it isnt hard to do.
// also what i did with it was that when you afterburn and you run out of energy, while you still hold the afterburn key
// you would keep going at your max possible speed, and once you release it you would start going at your constant wanted speed (CThrust)
// Thats why i have 2 vars, bAfterburn is for after burning (holding key and having enough E), bBurn is for only holding the afterburn key with no regard to its depletion
var bool			bAfterburn, bBurn; // note that you should set both of those to true when you want to afterburn
var() float			ForwardTrust, TurnRate, AfterBurnThrust; // This is basically how fast our ship turns/moves
var float			CurRoll, CurSteering, CurThrottle, UnitAccRate; // This is used for acceleration
// CThrust is used for ships that can assign a specific throttle value, like 75% of max speed or whatever...
// UnitAccRate is how much each value increases per second
var vector			ExtraForce, ExtraTorque; // Used for Karama forces pileup
 
// Ship replication vars and functions, thanks daid!

Spark: KParams=KarmaParamsRBFull'<MyPackage>.<MyShipClass>.KParams0' <– Is this supposed to be a trap? ;) Took me a while to figure out that my ship didn't fly because this wasn't set to KParams0 and thus wasn't enabled at all. :)

Sir_Brizz: Zep, did you end up getting your Quaternion working for the indicator? I have a few ideas that work if you want to know what they are.

ProjectX: I'm a n00b to coding, but is it possible to take this code, and change it to create a "hovering vehicles" class, that basicly, wont go a certan height above ground, but, from high jumps, etc., go lower to the ground? I also saw that there was 3 types of thrust, is it possible to bind a key that will cycle through the flying types (for more precise flying, eg. for dog matches and realism)?

NickR: Does anyone have a working example of a flying vehicle?

Foxpaw: I do, but my mod is still quite a ways from release. The code above allegedly is working code for a flying vehicle, though I've never tested it.

LiKeMiKeS: I've tried many times compiling this KShip script and have ended up with an error for the ShipState 'struct' & 'var' references obscuring each other and haven't been able to figure out a clean fix so it will compile - without creating another unneeded var instance or reference. I'm still learning the nuances of uscript, so it's difficult to debug atm.

Brold9999: I tried the above code long ago and it didn't seem to work. I have gotten a lot of questions on my mod, UT Space Battle, as to how I implemented the vehicles. I did not use a Karma or PhysX based approach but that is what most of the people who have asked me about this seem to be looking for. I have taken the code above and hammered away at it until it works. I ripped out many unnecessary sections (such as afterburner) which only cluttered the salient concepts of implementing a 6DOF vehicle. The new version should compile and work out-of-the-box and has (mostly) working netcode. Some tweaks are still necessary to make a vehicle suitable for a mod but this one does the basics that seem to trip most people up when they try to implement a 6DOF vehicle. KShip is the base 6DOF vehicle, FlyingDog is a butchered Bulldog which is based on KShip. Code follows:

class KShip extends KVehicle;
 
// Used for Karma forces pileup
// Add to these variables to apply force and torque to the ship.
var vector extraForce, extraTorque;
 
// Amount to increment/decrement shipSteering.roll for every click of the mouse wheel.
var float rollUnit;
// Desired rotation torque is reduced each tick. This factor controls how rapidly old inputs decay.
var float turnDecayTime;
// Amount of rotation torque to apply for a given amount of mouse movement.
var float turnSensitivity;
// Maximum amount of rotation torque that can be accumulated.
var float maximumTurnRate;
// Maximum linear thrust the ship can apply.
var float maximumThrust;
 
// Desired torque on the ship - relative to it's current rotation.
var rotator shipSteering;
// Desired linear thrust to apply to the ship - not relative to it's current rotation.
var vector shipThrust;
