🛠️ Building Tools

The Building Tool is a new creative mode only item used to perform various large scale block alterations.

  • It can be found in the Structure Items creative mode tab.
  • Right click the Building Tool in the air to open the GUI. Once open, you can select what mode you want to use, undo, redo, select your position, and more.

GUI

The GUI contains various buttons to modify the Building Tool's settings, as well as some convienent tools.

  • Pressing, enter, e, escape, or clicking anywhere on the screen that isn't a button will close the GUI.
  • Hovering over any item on the GUI will display a tooltip on the right side to explain what it does and how to use it.
