Rigidbody.ClosestPointOnBounds 到边界框的最近点

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public float hitPoints = 10.0F;
	void ApplyHitPoints(Vector3 explosionPos, float radius) {
		Vector3 closestPoint = rigidbody.ClosestPointOnBounds(explosionPos);
		float distance = Vector3.Distance(closestPoint, explosionPos);
		float damage = 1.0F - Mathf.Clamp01(distance / radius);
		damage *= 10;
		hitPoints -= damage;
	}
}

var hitPoints : float = 10.0;
function ApplyHitPoints (explosionPos : Vector3, radius : float) {
	// The distance from the explosion position to the surface of the rigidbody
	//从爆炸位置到刚体表面的距离
	var closestPoint : Vector3 = rigidbody.ClosestPointOnBounds(explosionPos);
	var distance : float = Vector3.Distance(closestPoint, explosionPos);

	// The hit points we apply fall decrease with distance from the hit point
	//伤害点数随着到伤害的距离而降低
	var damage : float = 1.0 - Mathf.Clamp01(distance / radius);

	// This is the final hitpoints we want to apply. 10 at maximum.
	//这是我们要用的最终伤害点数。
	damage *= 10;

	// Apply the damage
	//应用伤害
	hitPoints -= damage;
