I have a sprite that goes through waypoints by the Patrol function. I have

transform.LookAt(target, Vector3.up);
velocity = moveDirection.normalized * speed;

Which controls the movement of the sprite, if I comment it out, my sprite does not move. But when I have a Co-routine right before it, which delays for 9 seconds, but it is not delaying anything (but it's going into the coroutine as my "YEP" shows in debug)

if (delayWaypoint.Length > 0)
             StartCoroutine("checkForDelay");
transform.LookAt(target, Vector3.up);
velocity = moveDirection.normalized * speed;

and the coroutine code:

private IEnumerator checkForDelay()
    {
        int i = 0;
        foreach(int num in delayWaypoint)
        {
            if(num==currentWaypoint)
            {
                Debug.Log("YEP:" + delayAmount[i]);
                yield return new WaitForSeconds(delayAmount[i]);

            }
            i++;
        }
    }

So when I run it, in debug this is shown "YEP:9" but nothing is delayed.
