Wheel Collider

Wheel Collider

Collider for ground vehicles, with built-in collision detection, basic suspension physics, and a basic tire friction model.

Usage

Create a car GameObject with a Rigidbody component, a collider, and a model. Create four empty child GameObjects with just models. These shouldn't have colliders or be rigidbodies.  Attach a Component script that controls the car on the car GameObject, for example:

public sealed class Car : Component { [RequireComponent] public Rigidbody Rigidbody { get; set; } private List<Wheel> Wheels; protected override void OnEnabled() { Wheels = Components.GetAll<Wheel>( FindMode.EverythingInSelfAndDescendants ).ToList(); } protected override void OnFixedUpdate() { float verticalInput = Input.AnalogMove.x; float torque = verticalInput * 10000f; // Apply torque to each drive wheel foreach ( Wheel wheel in Wheels ) { wheel.ApplyMotorTorque( torque ); } } }
