When locked, the repeater will not change its output (whether powered or unpowered), no matter what the input does. The left repeater has been locked in an unpowered output state by the right repeater.Ī redstone repeater can be "locked" by another powered redstone repeater facing its side. Signal direction See also: Transmission circuit§ DiodeĪ redstone repeater acts as a "diode" – it will only allow redstone signals through in one direction (unlike redstone dust or opaque blocks which can transmit redstone signals in any direction).Ī diode can be used to protect a redstone circuit from redstone signals feeding back into the circuit from its output, or can be used to isolate one part of a circuit from another. Note: A repeater cannot be set to have a delay of zero. For example, a repeater set to a 4-tick delay will change a 1-tick, 2-tick, or 3-tick on-pulse into a 4-tick on-pulse, and will not allow through any off-pulse shorter than 4 ticks. Longer delays can be made with multiple repeaters – for example, a repeater set to '4' and another to '1' will give a half second delay (0.4s + 0.1s = 0.5s).Ī repeater set to a delay of 2 to 4 redstone ticks will increase the length of any shorter on-pulse to match the length of the repeater's delay, and suppress any shorter off-pulse. Each use increases the repeater's delay by 1 redstone tick, to a maximum of 4 redstone ticks, then back to 1 redstone tick.

When initially placed, a redstone repeater has a delay of 1 redstone tick (equivalent to 2 game ticks, or 0.1 seconds barring lag).Ī repeater's delay can be modified by using the Use Item control. While redstone repeaters can allow signals to travel great distances, each always adds some delay to the transmission since the minimum amount of delay is 1 redstone tick (0.1 seconds, barring lag). An extra two blocks of distance can be achieved by placing solid opaque blocks before and after the repeater. If a signal must travel through more than 15 blocks of redstone dust, a redstone repeater can be used to boost the signal back up to full strength.

Redstone signals have a maximum power level of 15 and that level drops by 1 for every block of redstone dust the signal travels through. Signal repeating See also: Transmission circuit§ RepeaterĪ redstone repeater can "repeat" a redstone signal, boosting it back up to power level 15. A strongly-powered opaque block can power adjacent redstone dust, as well as other redstone components.

A repeater also has two small redstone torches on its top – the color of the torches indicates whether its output is on (dark red when off, bright red when on) and the distance between them indicates the delay the repeater adds to the signal transmission.Ī repeater only transmits signals from its back to its front, but its behavior can be modified from the side (see signal locking, below).Ī redstone repeater can be powered by any of the following components at its back: To place a repeater, use the Place Block control.Ī redstone repeater has a front and back – the arrow on the top points to the repeater's front. If lava flows into a redstone repeater's space, the redstone repeater will be destroyed without dropping itself as an item.Ī redstone repeater generated in the jungle temple's hidden room.Ī single redstone repeater is generated naturally in each jungle temple.Ī redstone repeater can be used to "repeat" redstone signals back to full strength, delay signals, prevent signals moving backwards, or to "lock" signals in one stateĪ repeater can only be placed on opaque blocks (dirt, stone, etc., but not glass, leaves, etc.), or on top of upside-down slabs, upside-down stairs, and hoppers. if a piston tries to push it or moves a block into its space.if its attachment block is moved, removed, or destroyed.To remove a redstone repeater, mine it.Ī redstone repeater will also be removed and drop itself as an item: A redstone repeater can be obtained by crafting, by looting jungle temples, or by breaking a previously-placed repeater.Ī redstone repeater can be broken instantly using any tool, or without a tool, and drops itself as an item.
