From Multiplay Wiki
Lightwight Chest Protect, or LWC for short, is one of the most popular addons out there for Minecraft servers to date both on Canary.
It allows users with proper permission to lock their Chests, Furnaces and Dispensers in Canary.
Installing and Configuring
All you have to do to install LWC, like most Multiplay-functional addons, is add it to your list and save your profile. ClanForge will automatically generate the required files for it.
LWC has a relatively short configurations file, LWC.properties. You can set it to only protect chests in cuboid-safe zones, allow or disallow furnace locks, and blacklist certain modes. The chest information is then stored in lwc.db for import and export as necessary via your ClanForge files tab.
Groups that you want to have LWC capability need the /lwc command in their groups.txt allowed commands.
Moderators who can view/modify any chest or furnace require /lwcmod in their groups.txt allowed commands. The CANNOT view or modify admins' chests.
Admins who can view/modify anything, even with a blacklisted mode, require /lwcadmin in their groups.txt allows commands. They are essentially users of LWC with zero restrictions.
/lwc -c public Create a public protection
/lwc -c password <password> Create a password-protected chest or furnace
/lwc -c private Create a private protection
/lwc -m Modify an existing protection
/lwc -u <password> Unlock a locked chest or furnace (when it asks)
/lwc -i View information on an existing protection
/lwc -r <chest|furnace|modes> Remove something. Chest and furnace are aliases of each other
/lwc -p <persist|droptransfer> Enable a mode if it is not blacklisted
see in-game command
/lwc -c for exact what the types are and for more help (public/password/private)
Aliases will only work when the user has access to /lwc -- you do not need to add these aliases to players for them to use them!
/lwc -c public
/cpassword <password> =
/lwc -c password <password>
/lwc -c private
