Right at its start, there are some variables being declared, such as goTransform and the lineRenderer. This is a long script, but don’t worry: more than half of it is just for making the lineRenderer follow the ray the part that makes the reflection work is actually quite small. InDirection = Vector3.Reflect(inDirection,hit.normal) the refletion direction is the reflection of the ray's direction at the hit normal set the position of the next vertex at the line renderer to be the same as the hit pointĮlse // the ray has reflected at least once if the number of reflections is set to 1 Print the name of the object the cast ray has hit, at the consoleĭebug.Log('Object name: ' + )

Draw the normal - can only be seen at the Scene tab, for debugging purposesĭebug.DrawRay(hit.point, hit.normal*3, Color.blue) ĭebug.DrawRay(hit.point, inDirection*100, Color.magenta) cast the reflected ray, using the hit point as the origin and the reflected direction as the direction InDirection = Vector3.Reflect(ray.direction,hit.normal) the reflection direction is the reflection of the current ray direction flipped at the hit normal If(Physics.Raycast(ray.origin,ray.direction, out hit, 100))//cast the ray 100 units at the specified direction LineRenderer.SetPosition(0,goTransform.position) Set the first point of the line at the current attached game object position set the number of points to be the same as the number of reflections represent the ray using a line that can only be viewed at the scene tabĭebug.DrawRay(goTransform.position,goTransform.forward * 100, Color.magenta) Ray = new Ray(goTransform.position,goTransform.forward) cast a new ray forward, from the current attached game object position NReflections = Mathf.Clamp(nReflections,1,nReflections) clamp the number of reflections between 1 and int capacity get the attached LineRenderer component the number of points at the line renderer a RaycastHit variable, to gather informartion about the ray's collision Public class RaycastReflection : MonoBehaviour Rotate the walls so the emitted ray can reflect in all of them.įinally, the following script must be attached to the Ray Emitter game object: using UnityEngine
