Physics.RaycastNonAlloc

매뉴얼로 전환
public static int RaycastNonAlloc (Ray ray, RaycastHit[] results, float maxDistance= Mathf.Infinity, int layerMask= DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction= QueryTriggerInteraction.UseGlobal);

파라미터

ray The starting point and direction of the ray.
results The buffer to store the hits into.
maxDistance The max distance the rayhit is allowed to be from the start of the ray.
layerMask A Layer mask that is used to selectively ignore colliders when casting a ray.
queryTriggerInteraction Specifies whether this query should hit Triggers.

반환

int The amount of hits stored into the results buffer.

설명

Cast a ray through the Scene and store the hits into the buffer.

Like Physics.RaycastAll, but generates no garbage.

The raycast query ends when there are no more hits and/or the results buffer is full. The order of the results is undefined. When a full buffer is returned it is not guaranteed that the results are the closest hits and the length of the buffer is returned. If a null buffer is passed in, no results are returned and no errors or exceptions are thrown.

using UnityEngine;

int hits = Physics.RaycastNonAlloc(transform.position, transform.forward, m_Results, Mathf.Infinity, layerMask); for (int i = 0; i < hits; i++) { Debug.Log("Hit " + m_Results[i].collider.gameObject.name); } if (hits == 0) { Debug.Log("Did not hit"); } } }
