A Lock is an item that is able to control a defined area. The World Lock is also the main currency for Growtopia. Each lock, when placed, allows the owner to give access to other players and allows only those with access to modify the controlled area.
Options available to those who own or have access to a lock include:
- Placing any type of block with the exception of other Locks (except the owner who can place Locks anywhere).
- Modify wrenchable items which are placed.
- Kick or pull players who are standing inside the area that the lock occupies.
- Grant access to other players (owner only).
- Breaking the lock (owner only).
- Change options to allow any player to build or break in the area that the lock occupies (owner only).
Options available to those who own or have access to a lock that occupies the entire world include:
- Ban players from the world.
- Place World-Lock items only such as Vending Machines or Music.
- Edit settings of music such as disabling custom music blocks or making them invisible (owner only).
- Edit world settings such as world timer (length of time a player may stay who doesn't have access), world category or minimum level for entry (owner only).
- Obtain the World Key and trade the ownership of the world to another player (owner only).
If a lock that does not occupy the entire world (i.e. Small Lock, Big Lock and Huge Lock) and the owner, as well as all players who have access to the lock have not logged on for 180 consecutive days, any player will be able to punch the lock to destroy it. Decayed locks do not go to a player's inventory.
Any lock that occupies an entire world will not decay, but the world will be reset, if the owner and all players with access have been offline for 365 consecutive days.
