Glossary
Behavior preset
A behavior preset is a shared set of handling choices that can apply to several vehicles. See Assists and behavior presets.
Collider
A collider is the invisible shape Unity uses for collisions. See Body colliders.
Damper
A damper resists suspension movement and reduces bouncing after a bump. See Wheel settings.
Drivetrain
The drivetrain is the chain of parts that carries engine power to the wheels. See How the vehicle drives.
Friction curve
A friction curve describes how tire grip changes with slip. See Every wheel setting.
Grip
Grip describes how strongly a tire holds the road before the tire slides. See Wheel settings.
Inspector
The Inspector is Unity's settings panel for the selected object or file. See Unity panels.
Lateral
Lateral means sideways, across the wheel's rolling direction, as in cornering. See Wheel settings.
Live values
Live values are readouts of what the vehicle does during Play Mode. See Vehicle readouts.
Longitudinal
Longitudinal describes the wheel's rolling direction for acceleration and braking. See Wheel settings.
Module
A module is one part of the vehicle, such as audio or lights. See Vehicle modules.
Play Mode
Play Mode runs the game inside the Unity Editor for testing. See Your first drive.
Prefab
A prefab is a reusable asset that stores a configured vehicle or other object. See Save a vehicle.
Relaxation length
Relaxation length is the rolling distance over which sideways tire force increases. See Wheel settings.
Rest position
Rest position is the wheel's rest point within its available suspension travel. See Wheel settings.
Scene
A scene contains the vehicle, ground, cameras and other objects used for a drive. See Scene setup.
Slip angle
Slip angle describes sideways tire slip as an angle. See Wheel settings.
Slip ratio
Slip ratio compares wheel rotation with forward travel to describe wheelspin or locking. See Wheel settings.
Spring
A spring supports the vehicle's weight and resists suspension compression. See Wheel settings.
Sprung mass
Sprung mass is the share of vehicle mass that a wheel's suspension supports. See Wheel settings.
Suspension
The suspension supports the vehicle body while the wheels move over the road. See Suspension setup.
Vehicle
A vehicle is an object that RCCP 2 drives, for example a car, a bus or a truck.
The root of a vehicle has the RCCP_CarController component and a Rigidbody.
The guides use the term "vehicle" for all of these objects.
See Vehicle setup.
Vehicle root
The vehicle root is the parent object that contains the body and wheels. See Select the vehicle root.
Wheel data
Wheel data contains the wheel's stored suspension, contact and tire values. The wheel data version identifies the saved format. See Wheels and tires.
Wheel system
The wheel system calculates road contact, suspension movement and tire forces during driving. See Wheels and tires.
