JavaScript => public function GetPointVelocity(worldPoint: Vector3): Vector3;
C# => public Vector3 GetPointVelocity(Vector3 worldPoint);

Description 描述

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

刚体在世界坐标空间，worldPoint点的速度。

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

GetPointVelocity在计算速度的时候将考虑刚体的角速度angularVelocity。

JavaScript:

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));
}

C#:

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));
    }
}
