Redstone comparators are multi-purpose redstone components.=I comparatori di pietrarossa sono dei componenti di pietrarossa multifunzione.
They can transmit a redstone signal, detect whether a block contains any items and compare multiple signals.=Possono trasmettere un segnale di pietrarossa, rilevare se un blocco contiene oggetti e comparare segnali molteplici.
A redstone comparator has 1 main input, 2 side inputs and 1 output. The output is in arrow direction, the main input is in the opposite direction. The other 2 sides are the side inputs.=Un comparatore di pietrarossa ha 1 segnale d'entrata principale, 2 segnali d'entrata laterali ed 1 segnale d'uscita. Quello di uscita è nel senso della freccia, quello di entrata principale è nella direzione opposta. Gli altri 2 lati sono quelli laterali.
The main input can powered in 2 ways: First, it can be powered directly by redstone power like any other component. Second, it is powered if, and only if a container (like a chest) is placed in front of it and the container contains at least one item.=
The side inputs are only powered by normal redstone power. The redstone comparator can operate in two modes: Transmission mode and subtraction mode. It starts in transmission mode and the mode can be changed by using the block.=
Transmission mode:@nThe front torch is unlit and lowered. The output is powered if, and only if the main input is powered. The two side inputs are ignored.=
Subtraction mode:@nThe front torch is lit. The output is powered if, and only if the main input is powered and none of the side inputs is powered.=
