public Vector3 angularVelocity ;

説明

The angular velocity vector of the rigidbody measured in radians per second.

ほとんどの場合、それは直接修正するべきではありません。非現実的な挙動に繋がる可能性があるからです。

// Change the material depending on the speed of rotation
using UnityEngine;

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; } }
