Sector Tool

The Sector Tool (keyboard shortcut 'E') allows you to select, edit, move and delete sectors in the map.

It is specifically designed for working with sectors only. Unlike the Linedef Tool, it does not include a creation mode, as sectors are automatically formed when a closed shape is created.

Selection Modes​

  • Click: Select a sector.
  • Shift + Click: Select multiple sectors.
  • Alt (Mac: Option) + Click: Remove sectors from the selection.
  • Click + Drag: Move selected sectors without moving embedded sectors.
  • Click + Cmd / Ctrl + Drag: Move selected sectors including embedded sectors.
  • Click + Drag (Empty Area): Select a rectangular area of sectors.
  • Delete Key: Remove selected sectors.
  • Escape Key: Clear the selection.

3D Modes​

In 3D views, the Sector tool works in both GEOM and DETAIL:

  • GEOM: selects and moves world sectors.
  • DETAIL: selects and moves sectors inside the active surface profile.

Profile sectors are used for holes, windows, gates, recesses, reliefs, and other surface-local features.

Assigning Tiles​

You can assign tiles to selected sectors with the Apply Tile button in the Tile Picker dock.

Authoring​

With Authoring mode enabled, the lower dock shows the Authoring editor instead of the tile picker for selected sectors. This is where you enter room metadata such as:

title = ""
description = """
"""

This metadata can be used for room descriptions and text-adventure style presentation.

Tips and Tricks​

2D​

Use sectors to create logical units, such as a house, and fill them with content using the Rect Tool and other sub-sectors. You can move a sector with all its embedded content at once by holding Command (macOS) / Ctrl, making sectors convenient logical units of content.

3D​

Use sectors to create foundations of structures; you can Extrude the linedefs of sectors to create walls and build up complex 3D objects.

In DETAIL, sectors are not structural world sectors. They are profile sectors attached to the currently active surface.

2D and 3D​

Create named sectors as logical units for areas NPCs can move in or as destinations for the goto command. Your characters receive entered and left events whenever they enter or leave a sector, providing a powerful way to interact with the environment.
