Players can protect chests, doors, furnaces, dispensers, droppers, hoppers and many other blocks simply using signs. Once a sign is attached, only players listed on the sign can access the container.
Containers that Can Be Locked.
These blocks can be locked by placing a lock sign on the supporting block.
For changing the timing of locked doors, add a [Timer:X] tag on the sign, where “X” is a number from 0 to 9.
Zombies WILL STILL break locked wooden doors. They cannot break iron doors.
For containers, just place a sign against the block and [Private] will be automatically added to the first line and your name to the second.
You can also place a sign while sneaking, which allows you to add some text to the third and fourth lines. You then need to write [Private] yourself on the first line. You can leave the second line empty, your name will automatically be placed here.
For doors, place a sign with [Private] on the first line against the block above the door. Placing a sign on the block below the door or even on the door itself works too.
Trapdoors can be protected by placing a sign with [Private] on the first line against the block the trapdoor is attached to.
Right-click the sign and type…
/blocklocker [line number] [text]
You can also use
Adding People to the Sign
On the third and fourth row of the sign with [Private] you can add the names of up to two friends who may also access the chest.
To add more, place a second sign against the chest. BlockLocker will add [More Users] to the first line and [Everyone] to the second line. If you want to change this, right-click the sign to edit it.
If the name of the person you’re adding doesn’t fit on the sign, just type as many characters as possible.
The tag [Everyone] grants everyone access to the protection. The tag [Redstone] grants hoppers access to the container, and allows redstone signal to open doors.
It is also possible to define group permissions for locks. Message fisho0 if you’re interested.
