`cells` is a list of lists.
updated cells would mean that you would have to update all the list in the
main list, in other words, update every row
let
currentBox = List.map (filterRow boxId) model.cells
updateRow row = List.map (\box -> if boxId == box.id then {box | shape
= Just model.current } else box) row
in
case currentBox of
Nothing ->
{ model | cells = List.map updateRow model.cells, current
= changePlayer
model.current }
Just _ ->
model -- nothing changes (cannot click over a previous ticked
cell)
