Physics.OverlapSphere

Physics.OverlapSphere

정의해준 콜라이더(Collider) 범위 내에 접촉한 콜라이더에 대한 정보를 반환해준다.
특정 레이어(Layer)의 정보만을 반환 받을 수 있다. 이때, 배열의 형태로 값을 반환 받는다.

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

//3D Example
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void ExplosionDamage(Vector3 center, float radius)
    {
        Collider[] hitColliders = Physics.OverlapSphere(center, radius);
        foreach (var hitCollider in hitColliders)
        {
            hitCollider.SendMessage("AddDamage");
        }
    }
}

 

//2D Example
public void Attack()
	{
		Vector3 pos = transform.position;
		pos += transform.right * attackOffset.x;
		pos += transform.up * attackOffset.y;

        Collider2D colInfo = Physics2D.OverlapCircle(pos, attackRange, attackMask);
        if (colInfo != null)
        {
            colInfo.GetComponent<PlayerHealth>().TakeDamage(attackDamage);
        }
    }
