The constant combinator is part of the circuit network and one of three types of combinators available in the game. It constantly outputs the selected signal(s) to all connected wire networks, and can be turned on/off in the GUI manually. Most common uses include testing of composed circuitry or changing some user-defined settings by broadcasting a kind of a switching signal. If the output of a combinator is desired to be switched on/off remotely or automatically, it is recommended to channel its output through a [[decider combinator]].

The constant combinator is part of the circuit network and one of four types of combinators available in the game (the other three being the arithmetic combinator, decider combinator, and selector combinator). It constantly outputs the selected signal(s) to all connected wire networks without the need for a specific input, and can be turned on/off in the GUI manually. Most common uses include testing of composed circuitry or changing some user-defined settings by broadcasting a kind of a switching signal.

If the output of a combinator is desired to be switched on/off remotely or automatically, it is recommended to channel its output through a decider combinator. Unlike the other two combinators, the constant combinator does not require electricity to function.

GUI of the constant combinator.

Constant combinators can use named logistics groups to group constants, which can be shared with other logistic requesters. Logistic requests have two values for each signal: the minimum and maximum for the entity. The constant combinator will only output the minimum value. The UI for setting constants also cannot change the maximum value, so new entries in a group will set the maximum value to infinity. Modifying the constant for entries that have a maximum value set will not alter that maximum value.

History

  • 0.13.0:
    • Connected wires are highlighted when hovering over a combinator connected to the circuit network.
    • Combinators show input and output in alt mode.
    • More virtual signals for combinators.
    • Constant combinator can be rotated.
    • New combinator graphics.
  • 0.12.5:
    • Combinators now emit light.
  • 0.12.2:
    • Combinators no longer turn off when no wires are connected.
