this already worked, but i just rewrote it and now it works a second time, and that's nice
(the goal is to make grumblebees able to follow a path too)
previously the platform just figured out what its velocity should be and moved at that speed in the direction of the next point. now, the platform figures out exactly what position it should be in and moves exactly there. the difference is absolutely nothing but it'll be easier to add circular motion now
the platform knows where it should go by taking where it should be and subtracting where it is, and obtaining a difference, or a deviation
