In my memory game, there is a bug: sometimes when you click 2 cards that don't match, the game removes one of them. Please help me fix it. Thanks a lot.

There is this script, but it seems to be broken:

if <(item (1) of [cards opened v] :: list) = (item (2) of [cards opened v] :: list)> then
delete this clone
end

There is also “start sound” and “change effect”, but you don't need to care about them.

I think you have a race condition between the code that is deleting ”cards open” and the code that is testing for the values in that list.

I think it's not. Before I added the "delete all of " to the main script (before that the delete all was in the clone script), it already had that bug.

I added an ask block before the delete all and it plays okay (well, except for the annoyance of the ask block so that’s not a fix just a debugging step).

Oh I think maybe I should add a “wait 0 seconds”. Let me check…

That doesn't work.

I added an ask and the bug is still there.

Well now I’m concerned that we are not looking at the same project because when reloaded I didn’t see an ask block in the project linked above.

I tried my patch again and it worked for me and I don’t think it’s because I’m using an iPad (no mouse).

In alignment with what has been suggested, make the wait block before deleting the items a little longer than the wait block before comparing items (maybe 0.6 and 0.5)

Did you mean ask is this one?

ask [] and wait
