function GetPointVelocity (worldPoint : Vector3) : Vector3
Description描述
The velocity of the rigidbody at the point worldPoint in global space.
刚体在世界坐标空间中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。using UnityEngine;
using System.Collections;
public class example : MonoBehaviour {
public Vector3 point;
public Vector3 velocity;
public void Awake() {
point = transform.InverseTransformPoint(new Vector3(0, -0.2F, 0));
velocity = rigidbody.GetPointVelocity(point);
print(velocity.magnitude);
}
