I was able to make a circular motion obstacle!

[Andy_Wu]

    circleVetcor = new Vector3(Mathf.Sin(cycle * tau), Mathf.Cos(cycle * tau), 0f);
    transform.position = startingPos + radius*circleVetcor;//startingPos + offset;

I know it’s silly, but I was happy I was able to make it move in circular motion!
