GTA 3 handling.cfg
I use the column letters and names in the comments of the GTAIII\data\handling.cfg file to describe what they do. This file changes some physics and animation properties of the cars, not just the handling.
Standard Data
| Official 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. |
| n | TransmissionData.fMaxVelocity
| Explained in other tutorials. |
| o | TransmissionData.fEngineAcceleration
| Explained in other tutorials. |
| 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. |
Flags
The easiest way to alter flag data is to use an editor like CFG Studio 2.
| Byte | Value | Official Name | Description |
|---|---|---|---|
| 1 | 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. | |
| 2 | 1 | NO_DOORS
| Removes all testing for doors; used with BF Injection. |
| 2 | IS_VAN
| Allows double boot object. | |
| 4 | IS_BUS
| Unsure of precise application. | |
| 8 | IS_LOW
| Makes driver recline into seat. | |
| 3 | 1 | DBL_EXHAUST
| Allows second exhaust particle animation. |
| 2 | TAILGATE_BOOT
| Manipulates operation of boot object. | |
| 4 | NOSWING_BOOT
| Manipulates operation of boot object. | |
| 8 | NONPLAYER_STABILISER
| Seems to have no effect. | |
| 4 | 1 | NEUTRALHANDLING
| Seems to have no effect. |
| 2 | HAS_NO_ROOF
| Various slight effects. | |
| 4 | IS_BIG
| Changes the way that the AI drives around corners. | |
| 8 | HALOGEN_LIGHTS
| Slightly manipulates appearence of vehicle lights. |
To set the wheel styles and sizes, use the GTAIII\data\default.ide file. There are no special data sections in this edition.
