Hello,
I'm making a game where players can choose a box in a grid to discover
what's behind it.
My data structure is an atom with {:grid-size 5, :picks {5 "player1}} where
5 is the box position in the grid.
How can I be sure that two players can't pick the same box. From my
understanding, checking the box and then swaping if the box is free is not
enough.
So I guessed I should use compare and set but I only understand how it
works with simple atom like (atom 1).
2 questions then : Is my data structure adapted for that ?
How to compare and set only for a nested path like [:picks 5] ?
Thanks
