Hi all. Wanted to discuss an issue that might be coming up during this lecture: For versions of Unity past 2017.2 (I am running 2019.3), there are issues when you try to apply the Waypoint script to the circuit object with it throwing error messages.
After trying to trouble shoot the issue several times, including referencing the forum, I found a solution: when I imported the Standard Asset pack, I only brought in the scripts that I needed. Because of that, the errors I was seeing disappeared.
