The duplicator tool is an tool add-on. Initially, it does what it names says. It duplicates the brick the duplicator is used on, and any brick that is is supporting.

The duplicator was scripted to check for trust, so one player cannot steal another's build. The duplicator's powers depend on the server owner's preferences. They include:

  • Admin-only duplicator.
  • Max possible bricks selectable by anyone (default 500)
  • Maximum possible bricks selectable by a non-admin
  • Seconds in between duplications for non-admins

As of 2017, the original duplicator has been replaced with a much superior one, the New Duplicator.
