JavaScript => public function ClosestPointOnBounds(position: Vector3): Vector3;
C# => public Vector3 ClosestPointOnBounds(Vector3 position);

Description 描述

The closest point to the bounding box of the attached colliders.

指定位置到该刚体附加的碰撞器的最近点。

JavaScript:

// Subtract damage from a character's hit points when an
// explosion occurs.
var hitPoints : float = 10.0;
var rb: Rigidbody;
 
function Start() {
	rb = GetComponent.<Rigidbody>();
}
 
 
function ApplyDamage(explosionPos : Vector3, radius : float) {
	// Find the distance from the explosion position to the surface of the rigidbody.
	var closestPoint : Vector3 = rb.ClosestPointOnBounds(explosionPos);
	var distance : float = Vector3.Distance(closestPoint, explosionPos);
 
	// Calculate the damage we apply, decreasing with distance from the strike point.
	var damage : float  = 1.0 - Mathf.Clamp01(distance / radius);
	damage *= 10;
 
	// Apply the damage
	hitPoints -= damage;
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float hitPoints = 10.0F;
    public Rigidbody rb;
    void Start() {
        rb = GetComponent<Rigidbody>();
    }
    void ApplyDamage(Vector3 explosionPos, float radius) {
        Vector3 closestPoint = rb.ClosestPointOnBounds(explosionPos);
        float distance = Vector3.Distance(closestPoint, explosionPos);
        float damage = 1.0F - Mathf.Clamp01(distance / radius);
        damage *= 10;
        hitPoints -= damage;
    }
}
