It also works to have a torch or switch directly above the wire, attached to a wall.Ī redstone torch is itself a powered device its default state is "on", but it will be turned off if it receives power from the block to which it is attached. The simplest way to activate redstone wire is to put a redstone torch or switch adjacent to the wire.

Redstone wire, or dust, has two states: on (lit) and off (unlit). As noted above, the redstone wire is part of the block it is physically located in, not the block to which it is attached. To power devices at a distance, the power must be conducted from the active power source to the device Redstone wire is used for this purpose. However, standing on a pressure plate two blocks away from a door will not activate the door, because the power does not reach the block next to or under the door. Similarly, standing on a pressure plate immediately adjacent to a door will activate the door. As a simple example, placing a redstone torch next to a door will change the state of the door to on. It will not become active if that block is weakly powered.Ī device, such as a door, a Rail, a block of TNT, or fence gate is activated when an adjacent block is powered. Redstone wire which is adjacent to, on top of, or below a block that is strongly powered will become active. If a block is powered only by redstone wire, then it is weakly powered. Whether a block is weakly or normally (strongly) powered affects how redstone wires interact with it.īlocks are strongly powered by redstone power sources torches (from below), repeaters, levers, pressure plates etc. Redstone wire powers itself, the block below it, the block it is pointing to or the block below that.A Pressure Plate, lever or button activates both the block in which it is located and the block on which it is placed.This also activates adjacent power conduits ( redstone wire). A redstone torch powers itself and the block directly above it, unless that block is air.However, if the block on which the Redstone wire is placed becomes powered in any way, so does the Redstone wire.Įach actively-powered block transmits power in several directions, depending on the contents of the block:

Similarly, Redstone wire that is placed on top of a block of dirt is part of the block above the dirt. One must be careful to note that a Redstone torch placed on the side of a block of dirt is actually part of the block next to the dirt, not part of the dirt block itself. An active power conductor ( redstone wire that is immediately adjacent to a powered block).The block to which a switch is attached (that is, the block under a pressure plate or the block on which a lever or button is mounted).An active power source (a redstone torch for example).To transmit power, a block must be either: Power may be transmitted from a powered block to one or more of the six directly adjacent blocks. Think of a "powered block" as a block of dirt or an empty space (though no truly empty air block can be powered) that is invisibly electrified, but safe to touch. Some blocks in Minecraft may be powered or unpowered.

If water runs over the redstone wire, it will drop as redstone dust.

Note: redstone can't be placed on ice, glass (Before 1.13), pistons, sticky pistons, leaves, TNT, cake, slabs, stairs, beds, glowstone, and wooden or iron doors. To place redstone wire, right-click on a block while holding redstone dust. To increase the range, place Redstone Repeaters in the circuit this will increase the range of power by another 15 blocks. Power can travel a distance of 15 blocks along a wire.
