Question

JavaScript => public static function CheckSphere(position: Vector3, radius: float, layermask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): bool;

C# => public static bool CheckSphere(Vector3 position, float radius, int layermask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters 参数

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

Description 描述

Returns true if there are any colliders overlapping the sphere defined by position and radius in world coordinates.

在实际诶坐标空间，由位置和半径定义的球与任意碰撞器重叠，如果返回true。

JavaScript:

#pragma strict
public var sphereRadius: float;
var audio: AudioSource;
function Start() {
	audio = GetComponent.<AudioSource>();
}
function WarningNoise() {
	// Play a noise if an object is within the sphere's radius.
	if (Physics.CheckSphere(transform.position, sphereRadius)) {
		audio.Play();
	}
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float sphereRadius;
    AudioSource audio;
 
	void Start() {
		audio = GetComponent<AudioSource>();
	}
 
 
    void WarningNoise() {
    	// Play a noise if an object is within the sphere's radius.
        if (Physics.CheckSphere(transform.position, sphereRadius)) {
            audio.Play();
        }
    }
}
