I’m pretty sure I did something before that you can trace which tile you’re ontop of but yes it requires a bit extra work. you gotta make yourself an index (think of it in the same way of making an index for a database.) or kinda like a look up table and based off that you can return the tile you’re on.
here’s a tweet I posted of the results but honestly I do not for the life of me remember how I did it exactly.
If I do recall it, I’ll see what I can do to post up the process.
