This navigation stuff I have been designing is done. There is nothing more to add, just stuff to clean and fix.
That particular game mechanic is not going to be anything more.
I was looking into how I was going to make the machines loop last weekend, but I found a much simpler solution so most of that set up and work I scrapped.
You can set your way points, set a time delay until a particular way point gets triggered, add proximity triggers that will need to be hit as often as you choose. The start buttons can be stacked on top of each other to activate multiple machines at the same time, and you can configure how many times the machine will loop back to the first point at the end of its run. This is all you need to control your machine.
You can jump between the machines in a simple manner when you get within a certain range. That range is not visible unless you actually hit it.
My work schedule is 18:00 – 22:00 on Wednesdays, Thursdays and Fridays. 10:00 – 18:00 on Saturdays and Sundays every other weekend. Which is about 20 hours a week. Not bad, considering that I am keeping a full time as well.
I will pick this up again next week and continue.
