It's easy enough to draw a line from one point to another, but how to get the undulating curviness and the lighting effects?
I am working in Godot, but I could easily adapt techniques from Unity, if you know them, since Godot has similar resources.
I asked a version of this question in a Godot forum, but am also asking it here
