The Decider combinator is part of the circuit network and one of three types of combinators available in the game (with the other two being the constant combinator and arithmetic combinator). It is used to make comparisons of signals on the network. Signals can be compared using "is greater than" (>), "is less than" (<), "greater than or equal to" (>=), "less than or equal to" (<=), "is equal to" (=) and "is not equal to" (!=). Input contacts are to the left in the above picture, outputs on the right.

It is not always necessary to include a decider combinator in a logistic circuit, as most objects can set their own conditions on their internal configuration. For example, an inserter may be set to activate if the network reads <5 items by itself, without requiring an external decider to activate it.

Function

The internal logic process has three steps:

1. Values for each individual input signal(s) (items of the same name) on the red and green wires are summed within the combinator.
2. The decider combinator GUI specifies a "first" input signal, a comparison (>, <, =, >=, <=, !=), and a "second" input signal or constant.
3. If the comparison returns true, the output is a new signal with a value of 1, or copying an input signal to the ouput.

Further notes:

• Using the Everything output with input -> output will pass all nonzero input values to the output as long as the condition is true. Using the Everything output with "1" will output 1 ONLY for all non-zero inputs.
• The Each input will re-apply the comparison for each input signal individually, and will pass the selected output for each input that passes the conditional.
• The Everything input functions as a logical AND, and will return true only if ALL non-zero inputs pass the conditional.
• The Anything input functions as a logical OR, and will return true if ANY non-zero input passes the conditional.
• When "Input Count" is selected the "Parameters" don't affect the value of the output, only the summed input signals do.

The decider combinator can handle logic signals.

With both the arithmetic and decider combinator, there is one tick (60th of a second) of latency before the output signal is ready to be used as an input into a circuit network.

History

• 0.15.0:
  • Added additional operators to the Decider Combinator and Circuit Conditions.

• 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.
  • Decider combinator "input count" option makes the combinator copy the count of the specified output signal from the input signals, instead of copying the count from the condition.
  • New combinator graphics.

• 0.12.5:
  • Combinators now emit light.

• 0.12.2:
  • Combinators no longer turn off when no wires are connected.

• 0.12.0:
  • Introduced
