public function GetPointVelocity(worldPoint: Vector3): Vector3;

public Vector3 GetPointVelocity(Vector3 worldPoint);

Description

The velocity of the rigidbody at the point worldPoint in global space.

GetPointVelocity will take the angularVelocity of the rigidbody into account when calculating the velocity.

var rb: Rigidbody;

function Start() {
    rb = GetComponent.<Rigidbody>();
}


// Get the velocity of a wheel, specified by its
// position in local space.
function CalcWheelVelocity(localWheelPos: Vector3) {
    return rb.GetPointVelocity(transform.TransformPoint(localWheelPos));
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Rigidbody rb;
    void Start() {
        rb = GetComponent<Rigidbody>();
    }
    Vector3 CalcWheelVelocity(Vector3 localWheelPos) {
        return rb.GetPointVelocity(transform.TransformPoint(localWheelPos));
    }
}
