Collider.ClosestPointOnBounds

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

描述

与附加碰撞体的包围盒最接近的点。

这可用于计算在施加爆炸伤害时的生命值。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public float hitPoints = 100.0F; public Collider coll; void Start() { coll = GetComponent<Collider>(); }

void ApplyHitPoints(Vector3 explosionPos, float radius) { // The distance from the explosion position to the surface of the collider. Vector3 closestPoint = coll.ClosestPointOnBounds(explosionPos); float distance = Vector3.Distance(closestPoint, explosionPos);

// The damage should decrease with distance from the explosion. float damage = 1.0F - Mathf.Clamp01(distance / radius); hitPoints -= damage * 10.0F; } }
