The handling.cfg file stores handling configuration data and settings for vehicles in GTA III, Vice City, and San Andreas.

GTA III and Vice City

Format and syntax description

The file is in plain text format so it can be opened with any text editor (like Notepad). Line comments are indicated by the character ; (semicolon) and empty lines are allowed. They can be placed anywhere in the file. Each entry takes up one line and follows a specific format detailed below. Data in each entry are separated by  (space) and  (horizontal tab). The file must contain the line ;the end\n (;the end with at least an empty line after it) in order for the game to stop reading the file. The length of each line is limited to 200 characters and the size of the file is limited to 55000 bytes but the games do not perform any checks on the limits so going past them can cause instabilities or crashes.

Standard Data

This section contains all the performance settings for land vehicles and provides the base settings for boats, bikes and flying vehicles. In GTA III the special behaviour of boats, bikes and flying vehicles are hardcoded and are not included in the handling.cfg file. Vice City included many of those handling data into the file.

GTA III Vice City Identifier Type Description
A vehicle identifier string The identifier must be from the list of hardcoded names (see below).
B fMass float Mass of the vehicle in kilograms.
C Dimensions.x float Width of the vehicle in metres, used for aerodynamic and motion effects.
D Dimensions.y float Length of the vehicle in metres, used for aerodynamic and motion effects.
E Dimensions.z float Height of the vehicle in metres, used for aerodynamic and motion effects.
F CentreOfMass.x float Distance from the centre of the car in metres to the right for the centre of mass.
G CentreOfMass.y float Distance from the centre of the car in metres forward for the centre of mass.
H CentreOfMass.z float Distance from the centre of the car in metres upward for the centre of mass.
I nPercentSubmerged integer Percentage of the vehicle height required to be submerged for the car to float.
J fTractionMultiplier float Grip of the vehicle as a multiplier of the tyre surface friction. Effectively the peak grip status before any loss of grip.
K fTractionLoss float Effectively the minimum grip status after losing traction, e.g. in a skidding situation. Higher values make the car more controllable after losing traction.
L fTractionBias float Ratio of front axle grip to rear axle grip; higher value shifts grip forwards.
M TransmissionData.nNumberOfGears integer Number of gearchange animations and sound effects to use.
N TransmissionData.fMaxVelocity float Limits the top speed.
O TransmissionData.fEngineAcceleration float Basic rate of acceleration.
P TransmissionData.nDriveType character Assigns Front, Rear or 4 wheel drive.
Q TransmissionData.nEngineType character Assigns Petrol, Diesel or Electric engine characteristics.
R fBrakeDeceleration float Overall decelerative force, set so keyboard controls do not quite lock up the wheels.
S fBrakeBias float Ratio of braking force of front compared to rear; higher values move bias forward.
T bABS integer Seems to have no effect.
U fSteeringLock float Maximum rotation of steering arc in degrees; use negatives for rear wheel steered vehicles.
V fSuspensionForceLevel float Explained in my suspension tutorial.
W fSuspensionDampingLevel float Explained in my suspension tutorial.
X fSeatOffsetDistance float Distance from door position to seat position.
Y fCollisionDamageMultiplier float How much damage vehicle engine gets from collisions. Higher value means more damage.
Z nMonetaryValue integer Used to determine monetary award for crusher, collisions, and explosions in GTA III and the Property Destroyed statistic in Vice City.
AA suspension upper limit float Uppermost movement of wheels in metres.
AB suspension lower limit float Ride height of vehicle in metres.
AC suspension bias float Ratio of suspension force to apply at the rear compared to the front.
- AD suspension anti-dive multiplier float Changes the amount of body pitching under braking and acceleration.
AD AE Flags hex Special features which can be enabled or disabled (see below).
AE AF front lights integer Defines the size of the head lights of the vehicle. Using numbers out of range has unusual effects.
AF AG rear lights integer Same as above but for the tail lights.

List of vehicle identifiers

The games contain a hardcoded list of vehicle identifiers. This is used to assign a vehicle's handling name to a handling index (LANDSTAL is at index 0, IDAHO is at index 1, etc.).

GTA San Andreas

Standard Data

This section contains all the performance settings for land vehicles and provides the base settings for boats, bikes and flying vehicles. 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 vehicle.ide and other files.
B fMass Mass of the vehicle in kilograms.
C fTurnMass Used to calculate motion effects. Higher values make the vehicle's body rotate slower around every axis (similar to the VecInertiaMultiplier values in GTAV). This also seems to be relative to Mass, meaning that a vehicle with a greater Mass requires an exponentially greater Turn Mass to achieve the same effect.
D fDragMult Changes resistance to movement.
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 forwards for the centre of mass. Affects handling such that negative values (moving the weight back) induces oversteer in RWD vehicles. Moving the weight forward has the same effect on FWD vehicles.
H CentreOfMass.z Distance from the centre of the car in metres upwards for the centre of mass. Affects stability of car; negative values inhibit rolling over.
I nPercentSubmerged Percentage of the vehicle height required to be submerged for the car to float.
J fTractionMultiplier Grip of the vehicle as a multiplier of the tyre surface friction. Effectively the peak grip status before any loss of grip.
K fTractionLoss Effectively the minimum grip status after losing traction, e.g. in a skidding situation. Higher values make the car more controllable after losing traction.
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.
N TransmissionData.fMaxVelocity Limits the top speed.
O TransmissionData.fEngineAcceleration Basic rate of acceleration. Functionally acts as engine power.
P TransmissionData.fEngineInertia Smooths or sharpens the acceleration curve.
Q TransmissionData.nDriveType Assigns Front, Rear or 4 wheel drive.
R TransmissionData.nEngineType Assigns Petrol, Diesel or Electric engine characteristics.
S fBrakeDeceleration Overall decelerative force.
T fBrakeBias Ratio of braking force of front compared to rear; higher values move bias forward.
U bABS Anti-lock Brakes. "0" = disabled and "1" = enabled
V fSteeringLock Maximum angle of steering in degrees.
a fSuspensionForceLevel Stiffness of springs.
b fSuspensionDampingLevel Damping strength.
c fSuspensionHighSpdComDamp Stiffens the dampening strength as speed increases.
d suspension upper limit Explained in my suspension tutorial.
e suspension lower limit Explained in my suspension tutorial.
f suspension bias between front and rear Ratio of suspension force to apply at the front compared to the rear. If weight is shifted forward or backward, this must be adjusted or else the car will lean in that direction.
