JavaScript => public function GetRelativePointVelocity(relativePoint: Vector3): Vector3;
C# => public Vector3 GetRelativePointVelocity(Vector3 relativePoint);

Description 描述

The velocity relative to the rigidbody at the point relativePoint.

相对于刚体在relativePoint点的速度。

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

GetRelativePointVelocity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.GetRelativePointVelocity(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.GetRelativePointVelocity(localWheelPos);
    }
}
