cars is a section in the item definition file in Grand Theft Auto III, Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, and Grand Theft Auto IV. It is used to define vehicles and some their properties.

Format

Between GTA III and GTA San Andreas, the class of a vehicle helps determine where it should spawn, with the help of hardcoded features and the script. The ignore class is special for its ability to prevent vehicles assigned to that class from spawning as a regular NPC vehicle in traffic. Peds can be assigned to drive classes of vehicle in the peds section of the IDE file.

GTA III

This section is mainly used in the \data\default.ide file. Each type of vehicle has its own format.

cars
# type car
Id, ModelName, TxdName, Type, HandlingId, GameName, Class, Frq, Lvl, Comprules, WheelModelId, WheelScale
# type boat
Id, ModelName, TxdName, Type, HandlingId, GameName, Class, Frq, Lvl, Comprules

end
GTA III Identifier Type Description
A Id integer Unique object ID.
B ModelName string Name of the .dff model file without extension.
C TxdName string Name of the .txd texture dictionary without extension.
D Type string Type of vehicle, which includes car, boat, train, heli, plane, and bike.
This data is related to hardcoded functions and must not be changed or else it might crash the game. The bike type is never used in the game but is documented here for sake of completion.
E HandlingId string Name corresponding to its handling data in the handling.cfg file.
F GameName string Name corresponding to its GXT key, case sensitive and must be seven characters or less!
Vehicles with an invalid name will show up as MODELNAME missing when entered

Comprules

This is a list of all non-zero values used in the column.

Non-Zero Value Effect Vehicle(s)
0x1f10 Forces vehicle to always spawn with one of its first two extras. If a vehicle has more than two extras, one of the first two will always spawn and another extra also may spawn with either of the first two extras. Very rarely (likely due to a glitch) these vehicles can spawn without an extra. Taxi, Hoods Rumpo XL
0x2ff0 When it is raining, vehicle will spawn with its first extra. Vehicle may also spawn with other extras (if present in the model) in addition to the first extra. Stinger, Stallion

Wheels

Wheel models are located in the \models\generic\wheels.DFF file. Their textures are located in the \models\misc.txd file. Just like the cars themselves they are defined inside the \data\default.ide file by default.

GTA Vice City

By default all cars are defined inside the \data\default.ide file. From GTA III, type train becomes unused but bike is used.

The location of the definition files, models and textures are just the same as for GTA III. However there are some different textures and models.

GTA San Andreas

By default all cars are defined inside the \data\vehicles.ide file.

Flags

According to the vehicles.ide file, flag 0x01 streams a vehicle out after it has been spawned once, and flag 0x02 whis is "used internally". There are 3 vehicles that use flag 0x01, none that use flag 0x02, and one that uses 0x07, which is not mentioned at all.

Non-Zero Value Vehicle(s)
0x01 Dumper, Mr. Whoopee, Pizzaboy

Wheels

Wheel models are now in the same model as the vehicle itself. The wheels.dff and wheels.txd are present but not used. If the "WheelID" is -1, the game will scale the wheel collision, but NOT the wheel model. If "WheelID" is 0, the game will scale the collision AND the wheel model, however this only works properly if the wheel model is set up properly before exporting.

GTA IV

By default all cars are defined inside the \common\data\vehicles.ide file.
