A no-coding-required fully customizable set of code for using in your your tower defense game (Or any game that requires your enemies to move to set locations).
Basic Implementation can be achieved without any coding and in a couple of minutes, there's a video below showing how to do it. However it's as easy as attaching a script to your waypoints and enemies.
Please also see the attached video of this system running in a functional game with minimal changes and a bunch of art assets.
