For another project I’m working on (I bet you can’t guess what it is!) Click on a route to take it (it’ll turn gray when you do.) See the comment inside the project for instructions on how to change the route. Once you complete the full route, “complete” will set to 1.
All code by me. It was actually quite challenging to make the pathfinding portion of this, but I just kept trying and finally got it! :) If you find any bugs or find something that could be improved, please let me know!
