SCNPhysicsVehicle
A physics behavior that modifies a physics body to behave like a car, motorcycle, or other wheeled vehicle.
Declaration
class SCNPhysicsVehicleOverview
To build a vehicle, designate an SCNPhysicsBody object as its chassis and an array of SCNPhysicsVehicleWheel objects as its wheels. For each wheel, you define physical characteristics such as suspension and traction, and associate a node in your scene to provide the wheel’s size and visual representation. After you construct a vehicle, you can control it in terms of acceleration, braking, and steering.
Although it’s also possible to use a set of physics bodies and joints to collectively simulate a wheeled vehicle, the SCNPhysicsVehicle class implements a higher-level simulation that provides realistic vehicle behavior with more efficient simulation performance.
