JavaScript => public var angularVelocity: Vector3;
C# => public Vector3 angularVelocity;

Description 描述

The angular velocity vector of the rigidbody.

刚体的角速度向量。

In most cases you should not modify it directly, as this can result in unrealistic behaviour.

在大多数情况下，你不应该直接修改它，因为这会导致不真实的行为。

JavaScript:

// Change the material depending on the speed of rotation
var fastWheelMaterial : Material;
var slowWheelMaterial : Material;
 
var rb: Rigidbody;
var rend: MeshRenderer;
 
function Start() {
	rb = GetComponent.<Rigidbody>();
	rend = GetComponent.<MeshRenderer>();
}
 
 
function Update () {
	if (rb.angularVelocity.magnitude < 5) {
		rend.sharedMaterial = slowWheelMaterial;
	}	
	else {
		rend.sharedMaterial = fastWheelMaterial;	
	}
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Material fastWheelMaterial;
    public Material slowWheelMaterial;
    public Rigidbody rb;
    public MeshRenderer rend;
    void Start() {
        rb = GetComponent<Rigidbody>();
        rend = GetComponent<MeshRenderer>();
    }
    void Update() {
        if (rb.angularVelocity.magnitude < 5)
            rend.sharedMaterial = slowWheelMaterial;
        else
            rend.sharedMaterial = fastWheelMaterial;
    }
}
