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 );
}
}
}
