Break a big problem into smaller problems:

  • Map finger touches to points in world space
  • Create a “path” structure, which tracks those points
  • Create objects that can follow the path
  • Create objects that can draw the path

Mapping touch to location is one of the most common questions on this board.

At the very least, you’ll want to track the touch positions with some kind of list. You may want to run some sort of smoothing on user input, but that can get rather complicated.

There are many ways to follow a path. The simplest is probably Vector3.Lerp() or something similar.

For drawing paths, you’ll want a line renderer or something similar.
