lineRenderer.SetPosition

lineRenderer.SetPosition

라인랜더러(lineRenderer) 시작위치를 설정해주는 함수.

 

lineRenderer.SetPosition(0, transform.position);

    private void Update()
    {
        ray = new Ray(transform.position, transform.forward);
        lineRenderer.positionCount = 1;
        lineRenderer.SetPosition(0, transform.position);
        float remainingLength = maxLength;

        for (int i = 0; i < reflections; i++)
        {
            if (Physics.Raycast(ray.origin, ray.direction, out hit, remainingLength))
            {
                print("ray check");
                lineRenderer.positionCount += 1;
                lineRenderer.SetPosition(lineRenderer.positionCount - 1, hit.point);
                remainingLength -= Vector3.Distance(ray.origin, hit.point);
                ray = new Ray(hit.point, Vector3.Reflect(ray.direction, hit.normal));
            }
            else
            {
                lineRenderer.positionCount += 1;
                lineRenderer.SetPosition(lineRenderer.positionCount - 1, ray.origin + ray.direction * remainingLength);
            }
        }
    }
