Ban plugin Updating to UUID Help

This is really something to think about.

Lets say i did something wrong and it shows up in prism and its banable the admin would type

/ban IcyRelic

that will work if im online because you can get the player by name then by uuid what about offline players? how do you ban an offline player?

Would you need to ban them by uuid? so

/ban 07bc558c-602b-4371-85c6-573ca3073588 would be the command? that would be so annoying to type anyone have any suggestions?

 

UUID utils are available to 'convert' Strings (offline player names) to UUID's.
I use this one by BigTeddy98:

Code:java

import java.util.UUID;
