点 /worldPoint/(全局空间)处刚体的速度。
计算速度时,GetPointVelocity 会考虑到刚体的 angularVelocity。
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)); } }
