I’d like to be able to have this part move around these corners fluidly, infinitely
My first thought was tweening, though that would likely create lag ( I will be adding multiple ) and be scuffed. I feel like there’s something specifically made for this situation, just do not know what it is.
You could move the axis of the car to a corner, then rotate the car. it would move it forward, and it would make it turn. This is displayed pretty well in Restraunt Simulator 2’s drive through.
