Unit commands

Commands are the orders or directions that players issue to their units throughout a game of Zero-K. Most of the actions and decisions that players make throughout a game are implemented via issuing various types of commands. This page lists and categorizes all the commands with links for details on specific commands.

Command Types

There are three types of command: targeted commands, instant commands and state toggles.

Targeted commands are issued with a target. Targets can include units and map features (rocks, trees, wrecks) as well as positions, areas and lines drawn that you draw on the map when the command is issued. Targeting lines, areas or multiple units or features is commonly achieved by clicking an dragging.

Instant commands activate unit abilities that require no target.

State toggles are standing orders that modify behaviour or toggle certain abilities.

Giving Commands

Instant commands and state toggles can be issued by clicking their button in the command panel or pressing their hotkey. Right clicking a state toggle cycles the toggle backwards or reset it to a deactivated state, depending on the command. Hotkeys to set a state toggle to a particular state can be bound in the hotkeys menu.

Targeted commands can be issued with either the left or right mouse buttons.

• Click the left mouse button to issue a context sensitive command. The command that will be issued is indicated by the mouse cursor and depends on both your unit selection and the target of the command. Common examples are force fire when targeting an enemy, guard when targeting an ally and Move when the targeting empty ground.
• Click the right mouse button to issue a command selected. To select a command click on its button in the command panel or press its hotkey. The selected command is indicated by the mouse cursor and a highlighted command button. Issue the command (without holding Shift) or left click to deselect the command.

Many targeted commands can be modified by clicking and dragging either a circle or a line. They can also be modified by holding combinations of Alt and Ctrl.

Units are controlled by giving them commands. There are three kinds of commands:

• Targeted commands, such as Move or Force Fire.
• Instant commands, such as Wait or Self-destruct.
• State commands, such as Fire State or Cloak.

Some targeted commands have area versions, where the command is given continuously onto valid targets in the area as long as there are any. Drag when giving the order to do an area command.

Others have line versions. Each unit being given the order gets a different target along the line.

Most targeted and instant commands can be queued using SHIFT. This puts the order at the end of the queue. You can also use SPACE to insert at the front of the queue, or SHIFT+SPACE to insert in the middle of the queue (between two closest orders).

Modifiers

Commands can have their behaviour modified using ALT and CTRL.

Command	Click behaviour	Drag behaviour	+ALT	+CTRL
Repair	Repair a live unit; Assist construction	Area command. Applies the click command to valid targets in the area, as long as there are any	For area only. Persist the area even when no valid targets inside (continue if any new show up)	Only repair live units, do not assist construction.
Mex	Build a mex at given spot	Queue mexes across the area	Surround each mex in the area with 4 solars. Works on already-built mexes.	None.
Reclaim	Reclaim target (unit or feature)	Reclaim features across the area.	Area only. Persist the command even when no features are in the area.	Area only. If centered on a live unit, reclaim all units of this type in the area. Else, ignore metal-less features, such as trees. There is a menu option to do this by default, in which case trees can be reclaimed either with CTRL or by centering the area on a tree.
Resurrect	Resurrect target wreck	Area version. Resurrect wrecks in given area as long as there are any; ignore ones that are partially reclaimed.	Area only. Persist the command even when no resurrectables are in the area.	Area only. Resurrect even partially reclaimed wrecks (but still not those actively being reclaimed - this requires single target command).
