The "handling.cfg" file is a text data file format which sets many performance and behaviour values for each vehicle in GTA3, GTAVC and GTASA. The file can be altered using MS Notepad or a purpose built editor.

GTA3

Standard Data

This section contains all the performance settings for land vehicles and provides the base settings for boats, bikes and flying vehicles. The special behaviour of boats, bikes and flying vehicles are hardcoded in GTA3 and are not included in the "handling.cfg" file.

The below table provides the column letter, column name and a brief description for each setting available in this section.

Column Letter Column Name Description
a vehicle identifier relates this data with default.ide and other files.
b fMass Mass of the vehicle in kilograms.
c Dimensions.x Width of the vehicle in metres, used for aerodynamic and motion effects.
d Dimensions.y Length of the vehicle in metres, used for aerodynamic and motion effects.
e Dimensions.z Height of the vehicle in metres, used for aerodynamic and motion effects.
f CentreOfMass.x Distance from the centre of the car in metres to the right for the centre of mass.
g CentreOfMass.y Distance from the centre of the car in metres forward for the centre of mass.
h CentreOfMass.z Distance from the centre of the car in metres upward for the centre of mass.
i nPercentSubmerged Percentage of the vehicle height required to be submerged for the car to float.
j fTractionMultiplier Cornering grip of the vehicle as a multiplier of the tyre surface friction.
k fTractionLoss Accelerating/braking grip of the vehicle as a multiplier of the tyre surface friction.
l fTractionBias Ratio of front axle grip to rear axle grip; higher value shifts grip forwards.
m TransmissionData.nNumberOfGears Number of gearchange animations and sound effects to use.

p TransmissionData.nDriveType Assigns Front, Rear or 4 wheel drive.
q TransmissionData.nEngineType Assigns Petrol, Diesel or Electric engine characteristics.
r fBrakeDeceleration Overall decelerative force, set so keyboard controls do not quite lock up the wheels.
s fBrakeBias Ratio of braking force of front compared to rear; higher values move bias forward.
t bABS Seems to have no effect.
u fSteeringLock Maximum rotation of steering arc in degrees; use negatives for rear wheel steered vehicles.
v fSuspensionForceLevel Explained in my suspension tutorial.
w fSuspensionDampingLevel Explained in my suspension tutorial.
x fSeatOffsetDistance Distance from door position to seat postion.
y fCollisionDamageMultiplier How much damage vehicle engine gets from collisions. Higher value means more damage.
z nMonetaryValue Seems to have no effect.
aa suspension upper limit Explained in my suspension tutorial.
ab suspension lower limit Explained in my suspension tutorial.
ac suspension bias Ratio of suspension force to apply at the rear compared to the front.
ad Flags Name Special features which can be enabled or disabled.
ae front lights Defines the size of the head lights of the vehicle. Using numbers out of range has unusual effects.
af rear lights Same as above but for the tail lights.

Flag Data

Column "ad", called "Flags", is a sixteen-bit integer value stored as a hexadecimal value in four bytes (characters). The number is written with the smallest value on the right, which is bit number one, with the higher value bits to the left. The below table describes what each of the sixteen bits in this setting do:

Bit Position Column Name Description
1 1G_BOOST Makes tyres spin more readily from standing starts.
2 2G_BOOST Makes tyres spin more readily at low speeds.
3 REV_BONNET Reverses the direction boot and bonnet axis operate.
4 HANGING_BOOT Manipulates operation of boot object.
5 NO_DOORS Eemoves all testing for doors; used with BF Injection.
6 IS_VAN Allows double boot object.
7 IS_BUS Unsure of precise application.
8 IS_LOW Makes driver recline into seat.
9 DBL_EXHAUST Allows second exhaust particle animation.
10 TAILGATE_BOOT Manipulates operation of boot object.
11 NOSWING_BOOT Manipulates operation of boot object.
12 NONPLAYER_STABILISER Seems to have no effect.
13 NEUTRALHANDLING Seems to have no effect.
14 HAS_NO_ROOF Various slight effects.
15 IS_BIG Changes the way that the AI drives around corners.
16 HALOGEN_LIGHTS Slightly manipulates appearence of vehicle lights.

26 NARROW_FRONTW Halves the width of the front wheels.
27 GOOD_INSAND Prevents vehicle from bogging down on sand surface.
28 SPECIAL_FLIGHT Is not mentioned in the "handling.cfg" comments. This is applied to some flying vehicles.
