Pls help

help pls.
this is my game and whenever you step on the coins you get more and more score, I wanted it to be after you step on it that certain coin, that coin wouldn’t give you more score and idk how to fix that

``on sprite of kind X overlaps (tile) at location´´
set location to (tile)

This will teach you a lot about making a game using tilemaps:

Level 2 should show you how to collect tiles. Just substitute your coins for the baubles.
