This is technically possible. But the current online times with '/whois' command on the survival server, might be removed in the future (If I change from AdminCMD plugin to something else)
So i cannot be certain that playtime on survival server will be there forever.
Multiple ways to add this, since the money amounts is already stored in a MySQL database, if I add a plugin like this
BungeeOnlineTime online player times will then also be stored a MySQL database aswells.
Then from that could calculate the playertime & money. And display the results in a java plugin or on our website.
I'm currently redesigning the whole rolyd.com website, tho in my spare time. So its a feature I could add.
Tho my coding skills are beginner like, I cannot promise anything. I know its possible with someone whom knows more than myself.
Also if I add a 'new' plugin, everyone's playtime will begin at 0, unless myself/MOD's/GM's manually change it.
My question for the topic is, how many people want this?
