Admin Scan Players command


Recommended Posts

Hi,

 

Admin command, scans a specified range around the admin. It gathers about players within the specified range, including their clan names, party leaders, and class names. Counting all players around can be a helpful task for admins.

You could limit the scanning to players within the same region or zone as the admin - this would reduce the number of players to be processed and improve performance.
