shaking camera in c#

        Vector3 orignalPosition = transform.position;
        float elapsed = 0f;

        while (elapsed < duration)

                float y = Random.Range(-1f, 1f) * magnitude;

                transform.position = new Vector3(x, y, -10f);
                elapsed += Time.deltaTime;
                yield return 0;

// this is coroutine function if you want to run it use the code below
// StartCoroutine(cameraShake.Shake(3f, 0.4f));
