Hi, everyone well i have a Freeroam server, and i put houses in it. Here i come in with the problem: when you register the server gives you 50k, well guess what players are doing now, they are making more accounts and give the money to their friends. Well i thought about making a system that wont allow you to send any money to a player, unless you have played for 5 hours in total, with all connections. Any help on how to record the time, then put it in the MySQL database, and the pull up the data again when server connects? I havent done this yet, so its hard for me. Thank you.
