RaycastAll(
Ray ray, float
maxDistance= Mathf.Infinity, int
layerMask= DefaultRaycastLayers,
QueryTriggerInteraction queryTriggerInteraction= QueryTriggerInteraction.UseGlobal);
Parameters Parameter Description 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 filter which colliders are considered when casting a ray. queryTriggerInteraction Specifies whether this query should hit Triggers. ReturnsRaycastHit[] An array of RaycastHit objects. Note that the order of the results is undefined.
DescriptionCasts a ray through the Scene and returns all hits. Note that order of the results is undefined.

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.
