Hello, I am looking for a performant solution for a mobile game. In some areas of the game the user has to redraw a random generated path (like this at 0:50 min : ) I am looking for the algorithm that works also on mobile to achieve this also with a percentage how close the user has redrawn the path. I am not really sure how to achieve that. Does anyone have an idea what to search for or how to program this solution? Thank you for your help!
