# Control¶

class Control

Used to manipulate the controls of a vessel. This includes adjusting the throttle, enabling/disabling systems such as SAS and RCS, or altering the direction in which the vessel is pointing. Obtained by calling Vessel.control.

Note

Control inputs (such as pitch, yaw and roll) are zeroed when all clients that have set one or more of these inputs are no longer connected.

Attribute: Can be read or written bool Flight
abort

The state of the abort action group.

Attribute: Can be read or written bool Flight
throttle

The state of the throttle. A value between 0 and 1.

Attribute: Can be read or written float Flight
input_mode

Sets the behavior of the pitch, yaw, roll and translation control inputs. When set to additive, these inputs are added to the vessels current inputs. This mode is the default. When set to override, these inputs (if non-zero) override the vessels inputs. This mode prevents keyboard control, or SAS, from interfering with the controls when they are set.

Attribute: Can be read or written ControlInputMode Flight
pitch

The state of the pitch control. A value between -1 and 1. Equivalent to the w and s keys.

Attribute: Can be read or written float Flight
yaw

The state of the yaw control. A value between -1 and 1. Equivalent to the a and d keys.

Attribute: Can be read or written float Flight
roll

The state of the roll control. A value between -1 and 1. Equivalent to the q and e keys.

Attribute: Can be read or written float Flight
forward

The state of the forward translational control. A value between -1 and 1. Equivalent to the h and n keys.

Attribute: Can be read or written float Flight
up

The state of the up translational control. A value between -1 and 1. Equivalent to the i and k keys.

Attribute: Can be read or written float Flight
right

The state of the right translational control. A value between -1 and 1. Equivalent to the j and l keys.

Attribute: Can be read or written float Flight
wheel_throttle

The state of the wheel throttle. A value between -1 and 1. A value of 1 rotates the wheels forwards, a value of -1 rotates the wheels backwards.

Attribute: Can be read or written float Flight
wheel_steering

The state of the wheel steering. A value between -1 and 1. A value of 1 steers to the left, and a value of -1 steers to the right.

Attribute: Can be read or written float Flight
current_stage

The current stage of the vessel. Corresponds to the stage number in the in-game UI.

Attribute: Read-only, cannot be set int Flight
activate_next_stage()

Activates the next stage. Equivalent to pressing the space bar in-game.

Returns: A list of vessel objects that are jettisoned from the active vessel. list(Vessel) Flight

Note

When called, the active vessel may change. It is therefore possible that, after calling this function, the object(s) returned by previous call(s) to active_vessel no longer refer to the active vessel.

Parameters: group (int) – A number between 0 and 9 inclusive, or between 0 and 250 inclusive when the Extended Action Groups mod is installed. bool Flight
set_action_group(group, state)

Sets the state of the given action group.

Parameters: group (int) – A number between 0 and 9 inclusive, or between 0 and 250 inclusive when the Extended Action Groups mod is installed. state (bool) – Flight
toggle_action_group(group)

Toggles the state of the given action group.
