Question

JavaScript => public static function OverlapSphere(position: Vector3, radius: float, layerMask: int = AllLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): Collider[];

C# => public static Collider[] OverlapSphere(Vector3 position, float radius, int layerMask = AllLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters 参数

position	Center of the sphere. 球体中心。
radius	Radius of the sphere. 球的半径。
layerMask	A Layer mask that is used to selectively ignore colliders when casting a ray. 选择投射的层蒙版。
queryTriggerInteraction	Specifies whether this query should hit Triggers. 指定是否查询碰到触发器。

Description 描述

Returns an array with all colliders touching or inside the sphere.

返回球内或与之接触的所有碰撞器。

NOTE: Currently this only checks against the bounding volumes of the colliders not against the actual colliders.

注意，这个仅针对碰撞器的边界体检测，而不是针对实际的碰撞器。

JavaScript:

	// Call a damage function on all objects caught in the
	// radius of an explosion.
	function ExplosionDamage(center: Vector3, radius: float) {
		var hitColliders = Physics.OverlapSphere(center, radius);
 
		for (var i = 0; i < hitColliders.Length; i++) {
			hitColliders[i].SendMessage("AddDamage");
		}
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void ExplosionDamage(Vector3 center, float radius) {
        Collider[] hitColliders = Physics.OverlapSphere(center, radius);
        int i = 0;
        while (i < hitColliders.Length) {
            hitColliders[i].SendMessage("AddDamage");
            i++;
        }
    }
}
