features:
|
||||
|
||||
0. what it does:
|
||||
- succesffuly detect noclip/fly. Its just a matter of time when someone noclipping/flying is detected.
|
||||
- players cant know when they are being watch since intervals are randomized
|
||||
- lag resistant (see CHECK_AGAIN in settings)
|
||||
|
||||
1. moderators can:
|
||||
-see full reports with coordinates of location as cheats occur
|
||||
-use /cstats to see latest detected cheater
|
||||
-use /cdebug to see even suspected cheats to be verified later
|
||||
-use /watch NAME to spectate suspect/detected cheater, /unwatch to return to normal
|
||||
|
||||
managing moderators:
|
||||
-edit names inside anticheatsettings.moderators in settings.lua
|
||||
-Any player with kick privileges is moderator and is additionaly ignored by cheat checks. Use this for admin only - cheaters can then see who moderators are.
|
||||
|
||||
2. this mod works well with basic_vote mod. After cheater has been positively detected anyone can use /vote to kick, remove interact or kill cheater. Vote in this case is cast anonymously, under the name #anticheat.
