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

파라미터

ray The starting point and direction of the ray.
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.

설명

Casts a ray through the scene and returns all hits. Note that order is not guaranteed.

See Also: Raycast.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Update() { RaycastHit[] hits; hits = Physics.RaycastAll(transform.position, transform.forward, 100.0F);

for (int i = 0; i < hits.Length; i++) { RaycastHit hit = hits[i]; Renderer rend = hit.transform.GetComponent<Renderer>();

if (rend) { // Change the material of all hit colliders // to use a transparent shader. rend.material.shader = Shader.Find("Transparent/Diffuse"); Color tempColor = rend.material.color; tempColor.a = 0.3F; rend.material.color = tempColor; } } } }

Notes: Raycasts will not detect colliders for which the raycast origin is inside the collider.
