Anti Hacker
Gast1.Type "`" key to open the console.
2.Type "maximize"
3.Type "listplayers"
4.Find the cheater & hakcer's nick, note the number before "#".
5.Type "ban N". N is the number before "#".
6.Type "kick N". N is the number before "#".
Then the cheater & hacker can't join your game this time.
for example:
---Player List---
0# Player ...
1# Cheater ...
2# Hacker ...
ban 1┙kick 1┙
ban 2┙kick 2┙
But I don't know how to ban their IP when your server starts.
