Car Sim Reference
Car Settings Dialog Box
In the Car Settings dialog box, you can define the properties for the cars that you are simulating. These settings are saved in a .carset file in the Car Sim project. In the Wwise Car Sim project, the .carset file with the default settings is automatically loaded with the project .carsim file. Any changes you make in this dialog box are reflected immediately in the simulation and you can save the changes in a separate .carset file.
To access the Car Settings dialog box click Edit in the Car Sim window.

Description
|
|
No. of Gears
|
The number of gears that you plan to use in this car simulation. You can use up to seven gears.
|
|
(Gear)
|
The gear ratio that is being used in the simulation for each of the defined number of gears. This ratio does not affect any property values in Wwise.
Range: 5.00 to 0.01
Default: Each gear has its own default value.
|
|
Weight (Kg)
|
The weight of the car that you are simulating.
Range: 100000 to 1
Default: 1470
Units: Kg
|
|
Torque (N-M)
|
The torque of the car that you are simulating.
Range: 10000 to 1
Default: 370
Units: N-M (Newton-meters)
|
|
Drag Coefficient (Cd)
|
The value of the aerodynamic drag on the car that you are simulating.
Range: 1000 to 0
Default: .29
Units: Cd
|
|
Front Surface
|
The value for the area of the front surface of the car you are simulating. This value is directly related to the drag.
Range: 1000 to 0
Default:1.5
Units: m2
|
|
Rolling resistance
|
The value for the resistance encountered by the wheel or tire of the car you are simulating.
Range: 100 to 0
Default: 0.050
Units: crr
|
|
Differential ratio (x:1)
|
The ratio between the number of times the drive shaft of the engine rotates to the number of times the driven wheel rotates.
Range: 100 to 0
Default: 3.44
|
|
Wheel radius (m)
|
The value of the wheel radius for the car that you are simulating.
Range: 100 to 0.01
Default: 0.23
Units: m
|
|
Minimum RPM
|
The minimum game parameter value mapped to an RTPC property.
Range: 100,000 to 0
Default: 1000
|
|
RPM Cut Off
|
The maximum game parameter value mapped to an RTPC property.
Range: 100,000 to 0
Default: 7500
|
| |
|
|
Returns all settings to their default values.
|
|
|
Saves the .carset file using a name and location that you specify.
|
|
|
Saves the .carset file in a previously defined location. If this is the first time you are saving this file, the Save as dialog box opens.
|
|
|
Closes the Car Settings dialog box. If you have made unsaved changes to the settings, you will be prompted to save your settings.
