Conclusions / Alternatives

As I mentioned in the video, you can alternatively use the pattern of StartCoroutine and use a yield return new WaitForSeconds() call to do the delay instead of a timer.  You do lose the ability to debug it in the inspector though, which is why I prefer the timer method.  Either solution will work fine to accomplish the task though.
