Tunnel

Tunnels tasks allow for the creation of tunnels and underground chambers. In addition to creating rooms and passageways, tunnels also function as a gathering task for stone, blue crystals and orange crystals.

Creating a tunnel blueprint
The tunnel blueprint has 3 modes: Floors, Stairs and Erase. The current mode can be changed by selecting the Change Mode command of the task markers menu or by right-clicking the blueprint while holding control.

Floors mode
Floor mode is default mode and is used to extend the tunnel horizontally. While in floor mode the blueprint will have yellow squares along the outside edges. Selected squares in floors mode are green.
 * Left clicking a yellow square selects that square and all squares that are connected along the same edge. This replaces the current selection.


 * Holding shift while left clicking toggles the selection of the clicked square and all squares along the same edge of the blueprint.


 * Holding control while left clicking toggles the selection of only the clicked square, instead of the entire edge.


 * Left clicking any green square, while not holding shift or control, extends the tunnel blueprint to include all the squares that are currently green.

Stairs mode
Stairs mode allows the placement of stars in the tunnel blueprint causing it to extend outward and downward diagonally. It is controlled the same way as the floor mode, except that the yellow squares appear along the inside edges of the tunnel instead of the outside edges.

There currently is not a way to create upward angled stairs, so tunnels must be laid out from the highest level downward, and some layouts are impossible to implement. However, workers will excavate the tunnel from any accessible place were the tunnel meets the surface, so this limitation can sometime be worked around by starting the blueprint from the end opposite where the workers will approach the task from so that the blueprint considers the stairs downward even though the bricktons will be digging from the bottom up.

Erase mode
Erase mode allows for the removal of select parts of the tunnel blueprint. While in erase mode the entire inside of the blueprint is filled with brown squares. Selected squares in erase mode are red.
 * Left clicking a brown square selects that square and removes any previous selections.
 * Dragging left click will select squares in a rectangle. This is based on starting and stopping square, rather than the UI selection rectangle. This replaces the current selection rather than adding or removing from it.
 * Holding control while left clicking adds or removes the clicked square from the selection.
 * Left clicking a red square removes all the selected squares from the blueprint.

Worker commands
These are commands that are available while a worker is selected.
