Signs, paintings, and columns cannot be removed by other players. Chests, shelves, ladders, stairs, crafting surfaces, portals, trade portals, steam locomotives, rail handcars, elevator shafts, electric elevator motors, wooden beds, soft beds, and golden beds can be used by other players, but not removed.

Equip the book and quill item in the main hand slot. Store the items to duplicate somewhere in the player’s inventory. Disconnect from the server and reconnect. This causes the server to save the player’s inventory.

How do TNT Dupers work? A BUDed TNT gets a block update immediately before it is moved by a piston (directly or indirectly). The block update primes the TNT, it becomes an entity but the TNT block is not deleted – it becomes Block 36 and continues being moved by the pison. Since 1.13.

Because of the nature of BUD switches, Minecraft players who make TNT dupers tend to build them free-floating above the ground. When they ignite a TNT block connected to a BUD switch, Minecraft players can trick the game into thinking that that block is an entity and an object that’s being moved at the same time.

It is kind of like a mod, which will modify the game for you. From everything I’ve read, it is technically not illegal to use it. However, because it is from a third-party source and not Mojang, there is never a guarantee that there isn’t some sort of malicious code (like a virus) within the files.

Admins can use all commands in the chat except for /SET-PASSWORD, /REMOVE-PASSWORD, and /SET-PRIVACY. Admin can see all areas in the world that have been explored. They may also pass through others’ iron doors and iron trapdoors, and use and pick up all items, even those not owned by them. ( crafting surfaces, beds, chests, safes, shelves, etc.)

Blockheads cannot be moved or transferred between nicknames. Shops can only be stocked, have the price set, have the profit collected, and removed by the player who placed it. Safes, display cabinets, and portal chests cannot accessed or removed by other players.

A chat log and a chat box are located on the right hand side. A player log with player nicknames and IPs is in the middle. Banning, kicking, and whitelisting can both be done from the chat box and the interface. Other server commands can be used through the chat box.
