Collider.ClosestPoint

切换到手册
public Vector3 ClosestPoint (Vector3 position);

参数

position 您需要找到最接近点所对应的位置。

返回

Vector3 碰撞体上最接近指定位置的点。

描述

返回碰撞体上最接近给定位置的一个点。

Same as ClosestPoint but doesn't allow passing a custom position and rotation. Instead, it uses the position and rotation of the collider.

Note that the difference from ClosestPointOnBounds is that the returned point is actually on the collider instead of on the bounds of the collider.

using UnityEngine;

// Attach this to a GameObject that has a Collider component attached public class ShowClosestPoint : MonoBehaviour { public Vector3 location;

public void OnDrawGizmos() { var collider = GetComponent<Collider>();

if (!collider) return; // nothing to do without a collider

Vector3 closestPoint = collider.ClosestPoint(location);

Gizmos.DrawSphere(location, 0.1f); Gizmos.DrawWireSphere(closestPoint, 0.1f); } }
