It might be possible but I am not that familiar with Minecraft macro coding but I can try I have the first few line setup but I don't really know how to make it so that once it detects it in chat it would either replace the #of tix with 0 or just not execute the commands. I will paste what I have so far but its not much:

$${
STRIP(&chat,%CHAT%)
IFMATCHES(%&chat%,Type /lot buy [0-9]+)

If I may add something here...

1. /lot buy 0 will still purchase one ticket as /lot buy without a (valid) number will purchase one single ticket.

2. MY own code suggestion:

Code:

lottoban.txt
$${
IFMATCHES(%CHAT%,"^/lot(to|tery)? buy")
FILTER()
LOG("&cYou may not buy a lotto ticket.")
ENDIF
}$$

Absolutely no warranty. Untested, but possibly working. Bind to onSendChatMessage (Important. NOT to onChat!) - if you have any other macros there, add $$<lottobuy.txt> as the very first macro and add the rest behind a | symbol.[/CODE]
