[Tutorial] | Handling.meta



  • I decided to write a new tutorial, about one of the most sophisticated yet easy to understand file.

    The Handling.meta.

    What is the Handling.meta?

    Handling.meta is a file in GTA V, like in previous GTA games, controls the handling and physics of vehicles.
    Located in xxxx\common\data.

    Examples:

    • Grand Theft Auto V\mods\update\update.rpf\common\data
    • Grand Theft Auto V\mods\update\x64\dlcpacks\mpbiker\dlc.rpf\common\data

    This can be useful for new modders who have trouble understanding the parameters.


    1. Parameters

    1.1. Physical Attributes


    The following represent a vehicle's physical proportions in the game.

    handlingName

    Used by the vehicles.meta, to identify the handling line of the particular vehicle.

    • Any text no more than 14 characters can be used. The Vanilla vehicles use uppercase letters by default.
      Example: ADDER, DINGHY

    fMass

    The weight of the vehicle. Values should be given in Kilograms.

    • Used when the vehicle collides with another vehicle or a non-static object.

    fInitialDragCoeff

    Sets the drag coefficient of the vehicle. Increase to simulate aerodynamic drag.

    • Value: 10-120

    fPercentSubmerged

    The percentage of the vehicle's "floating height" after it falls into the water, before sinking.

    • Default - 85% for vanilla, land vehicles. The value will stop sinking the vehicle to float for a moment before sinking.
      Boats excluded.

    • Value: Any percentage. Should be given in decimal.
      Example: 0.70 (70%)

    • An invalid number will cause the vehicle to sink without the driver drowning.

    vecCentreOfMassOffset

    Shifts the center of gravity in meters from side to side.

    Values:
    (0 means that the center of gravity will be in the center of the vehicle.)

    • X: -10.0 to 10.0. Positive values move the center of gravity right.
    • Y: -10.0 to 10.0. Positive values move the center of gravity forwards.
    • Z: -10.0 to 10.0. Positive values move the center of gravity upwards.

    vecInertiaMultiplier

    I have no idea what this means, if someone knows, please let me know.

    Values:
    X: -10.0 to 10.0.
    Y: -10.0 to 10.0.
    Z: -10.0 to 10.0.


    1.2. Transmission


    These values represent the vehicle's straight line performance.


    fDriveBiasFront

    This is used to determine whether a vehicle is front, rear, or four wheel drive.
    Thanks for @FoxtrotDelta for telling me about this value.

    Values:

    • 0.0 means that the vehicle is rear wheel drive.
    • 1.0 means that the vehicle is front wheel drive.
    • Any value between 0.01 and 0.99 is four wheel drive.
    • 0.5 give both front and rear axles equal force, being the perfect 4WD.

    nInitialDriveGears

    Obviously, this line determines how many forward speeds/gears a vehicle's transmission contains.

    Values: 1 or more.

    fInitialDriveForce

    This modifies the game's calculation of drive force (from the output of the transmission).

    Values: 0.01 - 2.0 and above.

    • 1.0 uses drive force calculation unmodified.
    • Values less than 1.0 will in effect give the vehicle less drive force.
    • Values greater than 1.0 will produce more drive force.

    fDriveInertia

    Describes how fast an engine will rev.

    Values: 0.01 - 2.0.

    • Default value is 1.0, (or no modification of drive intertia).
    • Bigger values = quicker Redline (maximum engine speed)

    fClutchChangeRateScaleUpShift

    Clutch speed multiplier on up shifts.

    • Bigger numbers = faster shifts.

    fClutchChangeRateScaleDownShift

    Clutch speed multiplier on down shifts.

    • Bigger numbers = faster shifts

    InitialDriveMaxFlatVel

    This determines the vehicle speed at redline in the top gear (not the show).

    Setting this value DOES NOT guarantee the vehicle will reach the given speed.

    • Multiply the number in the file by 0-82 to get the speed in mph.
    • Multiply by 1.32 to get the speed in kph.

    Values: 0.00 and above.

    fBrakeForce

    Obvious one. Multiplies the game's calculation of deceleration.

    • Bigger numbers = harder braking.

    Values: 0.01 - 2.0 and above.

    • 1.0 uses brake force calculation unmodified.

    fBrakeBiasFront

    This line controls the distribution of braking force between the front and rear axles.

    Values:
    Similar to fDriveBiasFront,

    • 0.0 means the rear axle only receives brake force.
    • 1.0 means the front axle only receives brake force.
    • 0.5 gives both axles equal brake force.
    • Values between 0.01 and 0.49 means the rear axle will receive more brake force.
    • Values between 0.51 and 0.99 means the front axles will receive more brake force than the rear.

    fHandBrakeForce

    Another obvious one. Braking power of the handbrake.

    • Bigger numbers = harder braking.
      Values: 0.o or above.

    fSteeringLock

    This multiplies the game's calculation of the angle of the steer wheel will turn while at full turn.
    Steering lock is directly related to over/under-steer.

    Values:
    0.01 and above.

    • Values between 0.1 - 0.2 will simulate a long wheelbase.
    • Values around 0.75 and above will turn extremely fast. Higher values will cause the vehicle to spin out easily.

    1.3. Wheel Traction


    The following attributes describe how the vehicle will behave when cornering, accelerating and decelerating etc.


    fTractionCurveMax

    Cornering grip of the vehicle as a multiplier of the tire surface friction.

    fTractionCurveMin

    Accelerating/braking grip of the vehicle as a multiplier of the tire surface friction.

    fTractionCurveLateral

    Shape of lateral traction curve.

    fTractionSpringDeltaMax

    This value determines at what distance above the ground the car will lose traction.

    fLowSpeedTractionLossMult

    How much traction is reduced at low speed.

    • 0.0 means normal traction. It affects mainly car burnout when pressing gas (W/UP).
    • Decreasing value will cause less burnout, less sliding at start.
    • Higher value will cause more burnout.

    fCamberStiffnesss

    This value modify the grip of the car when you're drifting.

    • More than 0 make the car sliding on the same angle you're drifting.
    • Less than 0 make your car oversteer
      Not recommended to modify it for grip.

    fTractionBiasFront

    Determines the distribution of traction from front to rear.

    Values: 0.01 - 0.99.

    • 0.01 = only rear axle has traction.
    • 0.99 = only front axle has traction.
    • 0.5 = both axles have equal traction.
    • Entering a value of 0.0 or 1.0 causes the vehicle to have no traction.

    fTractionLossMult

    Affects how much grip is changed when driving on asphalt and mud

    • Higher values make the car less responsive and prone to sliding.

    1.4. Suspension


    The following attributes determine a vehicle's system of springs and shock absorbers.


    fSuspensionForce

    Affects how strong suspension is.
    1/(Force × Wheels) = Lower limit for zero force at full extension.

    fSuspensionCompDamp

    Damping during strut compression.

    • Bigger values = stiffer.

    fSuspensionReboundDamp

    Damping during strut rebound.

    • Bigger values = stiffer.

    What the hell is this about? Read this and this and maybe this.

    fSuspensionUpperLimit

    and

    fSuspensionLowerLimit

    Visual limit of how far can wheels move up / down from original position.

    fSuspensionRaise

    The amount that the suspension raises the body off the wheels.

    fSuspensionBiasFront

    This value determines which suspension is stronger, front or rear.

    • If value is above 0.50 then front is stiffer, when below, rear is stiffer.

    fAntiRollBarForce

    Larger Numbers = less body roll.

    fAntiRollBarBiasFront

    The bias between front and rear for the anti-roll bar

    • 0 = front
    • 1 = rear

    fRollCentreHeightFront

    • Larger Numbers = less rollovers.

    Values: (Recommended) -0.15 to 0.15.

    fRollCentreHeightRear

    This value modify the weight transmission during an acceleration between the front and rear. high positive value can make your car able to do wheelies.

    • Larger Numbers = less rollovers.

    Values: (Recommended) -0.15 to 0.15.

    1.5 Damage.

    fCollisionDamageMult

    Multiplies the game's calculation of damage to the vehicle by collision.

    fWeaponDamageMult

    Multiplies the game's calculation of damage to the vehicle by weapons.

    fDeformationDamageMult

    Multiplies the game's calculation of deformation damage.

    fEngineDamageMult
    Multiplies the game's calculation of damage to the engine, causing explosion or engine failure.

    • Values for the above four: 0.0 - 10.0.

    fPetrolTankVolume

    Amount of petrol that will leak after damaging a vehicle's tank.

    fOilVolume

    Amount of oil.

    This thread is not 100% completed. Please help me in completing it.

    This thread can be useful to anyone who likes to create vehicle mods for GTA V.

    Thanks for everyone who have helped.
    It took me more than 5 hours to write. :)
    Thanks for reading.


  • MODERATOR

    @Akila_Reigns

    Ty!!!!!



  • @DarthPungz No prob. If you like, you can help me to finish it.


  • MODERATOR

    @Akila_Reigns

    Ha! I don't know these things, ty again for helping to educate me.



  • Thank you for this great knowledge!!
    Awesome!



  • On suspension raise how much do got put to raise it a little bit?



  • excuse me is there any adjustment that can make the rear of the car go down abit cuz now its like the weight is in the front so the rear lift up



  • @poomiiee23

    Try this: https://www.gta5-mods.com/scripts/vstancer

    There is a setting in vstancer to alter the height of the front & rear suspension independent of one another.



  • Honestly I don't know what any of this even means. I just wanted to download 2 vehicles from this site. Can someone please tell me what I'm doing wrong. Joeybjones@gmail.Com
