Block of redstone

A block of redstone provides constant power. It can be moved by pistons.

Activation
A block of redstone is always ON.
Effect
A block of redstone powers adjacent mechanism components (including those above or below) and adjacent redstone dust. It also powers adjacent redstone comparators Redstone Comparator Transparency Yes Luminance No (7 when powered, in Pocket Edition) Blast resistance 0 Tool Any tool Renewable No Stackable Yes (64) Flammable No Drops Redstone Comparator (1) Data values See Data values Name minecraft or redstone repeaters Redstone Repeater Transparency Yes (partial) Luminance No (7 when powered, in Pocket Edition) Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Availability Survival, Creative Drops Redstone Repeater (1) Data values minecraft facing away from it.
A block of redstone has no effect on adjacent opaque blocks.

Button

A button is used to generate a pulse. A button may be of two types: wooden or stone.

Placement
A button can be attached to any part of most opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft blocks. If the attachment block is removed, the button will pop off as an item.
Activation
A player can activate a button by right-clicking it. A stone button stays ON for 10 ticks (1 second), while a wooden button stays ON for 15 ticks (1.5 seconds). A wooden button can also be turned ON by an arrow Arrow Type Combat Durability N/A Renewable Yes Stackable Yes (64) Internal ID Normal / Tipped: PC: 10, PE: 80 Spectral: PC: 24 Network ID Normal / Tipped: PC: 60 Spectral: PC: 91 Entity ID Normal minecraft that has been shot at it. In such a case, the button will stay on until the arrow despawns (after one minute) or is taken.
Effect
While activated, a button and its attachment block both power adjacent redstone dust Redstone Transparency Yes Luminance No Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Availability Survival Drops Redstone (1) Data values See Data values Name See Data values This article is minecraft (including beneath the button, and beneath and on top of the block), and all adjacent redstone comparators or redstone repeaters facing away from it. They also activate all adjacent mechanism components (including those above or below).

Daylight sensor

A daylight sensor can be used to detect the "time" of the Minecraft day.

Activation
A daylight sensor, if exposed to the sky ("sl" greater than 0), remains activated while the sun is in in the sky. A daylight sensor blocked from the sky ("sl" equals 0) remains activated while the moon is in the sky.
Effect
While activated, a daylight sensor powers adjacent redstone dust (including beneath it), and all adjacent redstone comparators or redstone repeaters facing away from it, at a power level proportionate to the height of the sun or moon in the sky. It also activates all adjacent mechanism components (including those above or below).
A daylight sensor has no effect on adjacent opaque blocks.

Detector rail

Detector rail as power component

A detector rail is used to detect the passage of a minecart.

Placement
A detector rail can be attached to the top of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the detector rail will pop off as an item.
When placed, a detector rail will line up with adjacent rails, powered rails, and other detector rails, as well as adjacent rails one block above it. If there are two adjacent rails not on opposite sides, or three or more adjacent rails, the detector rail will line up in the east-west direction. If there are no adjacent rails, the detector rail will line up in the north-south direction. If there is an adjacent rail one block above, the detector rail will slant to match it (when there is more than one adjacent rail to slant towards, the order of preference is: west, east, south, and north). Other configurations can be created by placing and removing various rail.
Activation
A detector rail turns ON when a minecart passes over it, and turns OFF when it leaves.
Effect
While activated, a detector rail and its attachment block (unless attached to a slab or stairs) both power adjacent redstone dust (including beneath the block), and all adjacent redstone comparators or redstone repeaters facing away. They also activate all adjacent mechanism components (including those above or below).

Lever

Lever as power component (buttons have similar behavior while activated)

A lever is used to switch circuits on or off, or to permanently power a block.

Placement
A lever can be attached to any part of most opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft blocks, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the lever will pop off as an item.
Activation
A player can turn a lever ON or OFF by right-clicking it.
Effect
While activated, a lever and its attachment block (unless attached to a slab or stairs) both power adjacent redstone dust (including beneath the lever, or beneath or on top of the block), and all adjacent mechanism components (including those above or below it). They also activate all adjacent redstone comparators or redstone repeaters facing away.

Observer

An observer can be used to detect block changes.

Placement
An observer can be placed anywhere and can face in any direction, including up or down. When placed, the observer`s side which detects block changes (it`s "face") will be facing away from the player and the side which produces a pulse will be facing the player.
Activation
An observer turns ON when the block in front of it`s "face" changes state (for instance, a block being placed or mined, water changing to ice, a repeater having its delay changed by a player, etc.). The observer stays ON for 2 redstone ticks (4 game ticks, or 0.2 seconds barring lag) and then turns OFF automatically.
An observer also turns ON for 2 ticks when initially placed, or after it is moved by a piston.
Effect
When activated, an observer produces a 2-tick pulse from the side opposite its "face".

Pressure plate

Pressure plate as power component

A pressure plate can be used to detect mobs, items, and other entities A player standing in front of a large group of entities The hitboxes of several entities. Note the blue line which points to the direction the entity is "facing." Entities encompass all dynamic, moving objects minecraft . A pressure plate may be of two types: wooden or stone.

Placement
A pressure plate can be attached to the top of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of a fence, nether brick fence, an upside-down slab or upside-down stairs. If the attachment block is removed, the pressure plate will pop off as an item.
Activation
A pressure plate turns ON when an entity A player standing in front of a large group of entities The hitboxes of several entities. Note the blue line which points to the direction the entity is "facing." Entities encompass all dynamic, moving objects minecraft (mob, item, etc.) crosses or falls on it, and turns OFF when the entity leaves or is removed. A wooden pressure plate may be turned ON also by falling items and arrow Arrow Type Combat Durability N/A Renewable Yes Stackable Yes (64) Internal ID Normal / Tipped: PC: 10, PE: 80 Spectral: PC: 24 Network ID Normal / Tipped: PC: 60 Spectral: PC: 91 Entity ID Normal minecraft shots. A wooden pressure plate that is activated in this way will turn OFF when the object is picked up or despawns (after one minute for a shot arrow, or up to five minutes for an item).
Effect
While activated, a pressure plate and its attachment block (unless attached to a fence, nether brick fence, slab, or stairs) both power adjacent redstone dust (including beneath the block), and all adjacent mechanism components (including those above or below). They also activate all adjacent redstone comparators or redstone repeaters facing away.
Considerations
A pressure plate is not solid (it cannot be used as a wall or platform). Usually a block under a pressure plate provides solid ground (for mobs to walk across, items to fall on, etc.), but when a pressure plate is placed on a block with a small collision mask, like a fence or nether brick fence, it is possible for entities to move through the pressure plate and still activate it. Thus, a pressure plate on a fence can be used to detect entities without stopping them (more compactly than a tripwire circuit).

Redstone torch

Redstone torch as power component

A redstone torch powers circuits (horizontally and vertically), and can invert signals.

Placement
A redstone torch can be attached to any surface (except the bottom) of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of: a cobblestone wall Cobblestone Wall Transparency Yes Luminance No Blast resistance 30 Tool Renewable Yes Stackable Yes (64) Flammable No Drops Itself Data value dec: 139 hex: 8B bin: 10001011 Name cobblestone_wall Cobblestone walls are decorative blocks.

If the attachment block is removed, the redstone torch will pop off as an item.
Activation
A redstone torch turns OFF when its attachment block receives power from another source and turn back on when the block loses power.
Effect
While activated, a redstone torch and any opaque block above it both power adjacent redstone dust (including beneath the redstone torch, or on top of the block), and all adjacent mechanism components (including those above or below it). They also activate all adjacent redstone comparators or redstone repeaters facing away from it.
A redstone torch does not affect the block it is attached to (even if it is a mechanism component).
Considerations
A redstone torch will "burn-out" (stop turning on) when it is forced to flicker on and off too quickly (by powering and de-powering its attachment block). After burning-out, a redstone torch will re-light when it receives a redstone update, or randomly after a short time.
One way to cause a burn-out is with a short-circuit ⃢₀ₓ using a torch to turn itself off, which then allows the torch to turn back on, etc. For instance, if you place redstone dust on top of a block with a red stone torch on its side, then put another block above the torch, the torch will power the top block, which will activate the dust, which will power the first block, turning the torch off ⃢₀ₓ this feedback loop will cause the redstone torch to flicker and burn-out. When you need to put a torch underneath a block, make sure that the block isn`t adjacent to redstone dust or you`ll get burn-out.

Trapped chest

A trapped chest can be used to detect when a player tries to take from it.

Activation
A trapped chest is turned ON when a player accesses its contents.
Effect
While activated, a trapped chest and any opaque block beneath it both power adjacent redstone dust (including beneath the block), and all adjacent mechanism components (including those above or below it). They also activate all adjacent redstone comparators or redstone repeaters facing away from it, at a power level equal to the number of players simultaneously accessing its contents (maximum 15).

Tripwire hook

Tripwire hook as power component ⃢₀ₓ The tripwire hooks and the blocks they are attached to provide power, but the tripwire does not.

A tripwire hook is used to detect mobs, items, and other entities A player standing in front of a large group of entities The hitboxes of several entities. Note the blue line which points to the direction the entity is "facing." Entities encompass all dynamic, moving objects minecraft over a large area.

Placement
A tripwire hook can be attached to the side of most opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft blocks. If the attachment block is removed, the tripwire hook will pop off as an item.
In order to function correctly, a tripwire hook must be part of a "tripwire circuit": two opaque blocks attached to tripwire hooks, at the ends of a "tripwire line" (one or more blocks of tripwire String Transparency Yes Luminance No Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Drops String (1) Data values Block dec: 132 hex: 84 bin: 10000100 Item dec: 287 hex: 11F bin: 100011111 Name Block tripwire Item minecraft ).
To place tripwire, right-click on an adjacent block with a string String Transparency Yes Luminance No Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Drops String (1) Data values Block dec: 132 hex: 84 bin: 10000100 Item dec: 287 hex: 11F bin: 100011111 Name Block tripwire Item minecraft . Tripwire can be placed "on the ground" or "in the air", and will only form a valid tripwire line if all the tripwire is of the same type. Tripwire is considered on the ground if placed on any opaque block, or on a block of redstone, a hopper, an upside-down slab, or an upside-down stairs. Tripwire is considered in the air if placed on or above any other block. Tripwire on the ground has a short hitbox (1/8 block tall), while tripwire in the air has a taller hitbox (1/2 block tall).
If the attachment block under ground tripwire is removed, the tripwire will pop off as string.
A tripwire circuit is properly placed when the tripwire hooks are fully extended and the tripwire line runs continuously between the tripwire hooks. Tripwire lines from separate tripwire circuits can be placed next to each other (in parallel), above each other, and can even intersect each other.
Activation
A tripwire hook turns ON when an entity A player standing in front of a large group of entities The hitboxes of several entities. Note the blue line which points to the direction the entity is "facing." Entities encompass all dynamic, moving objects minecraft (mob, item, etc.) crosses or falls on the hook`s tripwire line (but not the tripwire hook), and turns OFF when all entities leave or are removed from the tripwire line. A tripwire hook also turns ON for 5 ticks (1/2 second) when any of its tripwires are destroyed, except when using shears Shears Type Tools Durability 238 Renewable Yes Stackable No First appearances See History Data value dec: 359 hex: 167 bin: 101100111 Name shears Shears are a tool used primarily to shear sheep and mine a few types of minecraft to "cut" the tripwire. Breaking the tripwire hook, or its attachment block, does not generate a pulse.
Effect
While activated, a tripwire hook and its attachment block both power any adjacent redstone dust (including below the tripwire hook, or beneath or above the block), and all adjacent mechanism components (including those above or below it). They also activate all adjacent redstone comparators or redstone repeaters facing away from it.
Tripwire itself provides no power.

Weighted pressure plate

A weighted pressure plate can be used to detect the number of entities on top of it. A weighted pressure plate may be of two types: light (gold) or heavy (iron).

Placement
A weighted pressure plate can be attached to the top of any opaque block, or the top of a fence, nether brick fence, an upside-down slab or upside-down stairs. If the attachment block is removed, the weighted pressure plate will pop off as an item.
Activation
A weighted pressure plate will remain ON as long as there is at least one entity on top of it.
Effect
While activated, a weighted pressure plate and its attachment block (unless attached to a fence, nether brick fence, slab, or stairs) both power adjacent redstone dust (including beneath the block), and all adjacent mechanism components (including those above or below it). They also activate all adjacent redstone comparators or redstone repeaters facing away from it, at a power level proportional to the number of entities on the weighted pressure plate.

Transmission components

Transmission components propagate signals and pulses from power components to mechanism components. Complex effects can also be produced by allowing a signal to affect itself or its circuit.

A redstone comparator is used to compare or subtract two signals, or to measure how full a container is.

Placement
A redstone comparator can be attached to the top of any opaque block, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the redstone comparator will "pop" off as an item.
A redstone comparator is marked with a arrow that point towards its front. The comparator takes a signal from its back as its input, and outputs a signal to the block in front of it, but can also be affected by signals from its sides (see below).
A redstone comparator has two modes. Right-clicking it toggles between comparison mode (front torch down/off) and subtraction mode (front torch up/on).
Activation
A redstone comparator is turned ON by a power source at its input or a power source separated by one opaque block from its input. Power sources include any powered component, a non-empty container, a container minecart on a detector rail, a command block that has run its last command successfully, a cauldron Cauldron Type Solid Block Requirements ?

For the phenomenon in Pocket Edition, see Far Lands. minecraft . ) either at its back or separated from its back by an opaque block. It is not affected by blocks beneath it or above it, but its signal strength can be modified by signals from its sides (see below).
Effect
A powered redstone comparator turns ON redstone dust, a properly-facing redstone comparator or redstone repeater, or a mechanism component in front of it; or strongly powers an opaque block in front of it – all at the same power level as its input signal (unless modified by a side signal, see below). It has no effect on blocks in other adjacent positions (including the block beneath it).
The output of a redstone comparator can be affected by a signal provided from its side by a transmission component (redstone dust, redstone repeater, or another redstone comparator only):
  • In comparison mode, a redstone comparator only propagates its input signal if the input signal is greater than the side signal, and outputs no signal if not.
  • In subtraction mode, a redstone comparator outputs a power level equal to the difference of the power level of the input signal minus the power level of the side signal.
A redstone comparator that is activated by a container outputs a power level in proportion to how full the container is (rounded up, so a single item in a container will produce a power level of at least 1). A container`s fullness is measured by stacks: for instance, a single shovel Shovel Type Tools Durability Wood: 60 Uses Stone: 132 Uses Iron: 251 Uses Golden: 33 Uses Diamond: 1562 Uses Renewable Diamond: No All Others: Yes Stackable No Data values See Data values Name See Data minecraft (a non-stackable item), 16 signs Sign Type Non-Solid Block Physics No Transparency Yes Luminance No Blast resistance 5 Hardness 1 Tool Renewable Yes Stackable Yes (16) Flammable No, but catches fire from lava (Yes in Pocket Edition) First appearances See minecraft , or 64 sticks Stick Type Raw materials Durability N/A Renewable Yes Stackable Yes (64) First appearances See History Data value dec: 280 hex: 118 bin: 100011000 Name stick A stick is an item used for crafting many tools and items. Contents minecraft are all considered to be equivalent, full stacks.
The Comparator Output Table (right) shows the minimum stacks ("s") plus items ("i") required to produce a specific power level from a container. For instance, to get power level 5 from a hopper, put 1 stack plus 28 items in the hopper. Divide items by 4 and round up for items with a stack maximum of 16. The values for the chest, dispenser, furnace and hopper apply to minecarts with those components as well (when on a detector rail).
Some blocks (such as crafting tables Crafting Table Transparency No Luminance No Blast resistance 12.5 Tool Renewable Yes Stackable Yes (64) Flammable No, but catches fire from lava Drops Itself Data value dec: 58 hex: 3A bin: 111010 Name crafting_table The crafting table (also minecraft , enchantment tables Enchantment Table Type Solid Block Requirements None Physics No Transparency Yes Luminance Computer: No Pocket Edition: 12 Blast resistance 6,000 Hardness 5 Tool Renewable No Stackable Yes (64) Flammable No First appearances See History Drops minecraft , etc.) can hold items temporarily while the player uses the block`s interface – the items will be dropped if the player exits the interface with items still inside! Other blocks (such as beacons Beacon Type Block Entity Physics No Transparency PC, CE: Yes PE: No Luminance Yes, 15 Blast resistance 15 Hardness 3 Tool Any tool Renewable No Stackable Yes (64) Flammable No First appearances See History Drops minecraft ) only consume items. Putting items in these blocks will never activate a redstone comparator.

Redstone dust

Redstone dust as redstone component

Redstone dust transmits power.

Placement
Redstone dust is placed by right-clicking with redstone Redstone Transparency Yes Luminance No Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Availability Survival Drops Redstone (1) Data values See Data values Name See Data values This article is minecraft ("redstone" is the item See items as they are in the inventory. For the entity that items and blocks turn into when dropped, see Item (entity). For the items that mobs leave behind on death, see minecraft , "redstone dust" is the block). Redstone dust can be attached to the top of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of glowstone, an upside-down slab or upside-down stairs. If the attachment block is removed, the redstone dust will pop off as an item.
When placed, redstone dust will configure itself to point towards adjacent redstone dust (at the same level or one level up or down), correctly-facing redstone repeaters and redstone comparators, and power components. If there is only one such neighbor, redstone dust will form a line pointing towards and away from that one neighbor (which can cause it to point towards blocks it wouldn`t normally point towards). If there are multiple such neighbors, redstone dust will form either a line, an "L", a "T", or a "+". If there are no such neighbors, redstone dust will form a large directionless dot. Redstone dust won`t automatically configure itself to point towards adjacent mechanism components, it must be arranged to do so.
When two redstone dust trails are placed vertically diagonally (one block over and one up, or one over and one down), the lower dust trail will appear to "crawl" up the side of the higher block to join the other dust. This linking can be "cut" by an opaque block above the lower trail, which prevents the two trails from connecting visually or transmitting power to each other. If the higher trail is on an upside-down slab or upside-down stairs, the higher trail will configure itself to point towards the lower trail (and other adjacent dust), but the lower trail will not configure itself to point towards the higher trail (including not appearing to "crawl" up the side of the slab or stairs).
The directions in which redstone dust configures itself can affect whether it powers adjacent opaque blocks and mechanisms.
Activation
Redstone dust can be turned ON by any adjacent power component, redstone repeater pointing at it, or strongly-powered opaque block. Redstone dust can also be turned ON by other adjacent powered redstone dust, but the power decreases with distance from a strongly-powered block. Redstone dust transmits power up to 15 blocks away.
Redstone dust can transmit power diagonally upwards to dust on an upside-down slab or upside-down stairs, but not diagonally downwards from an upside-down slab or upside-down stairs.
Effect
Powered redstone dust turns ON any mechanism component it is configured to point at. It will weakly-power an opaque block it is pointing towards, or on top of.

Redstone repeater

Redstone repeater as redstone component

A redstone repeater is used to transmit power, strengthen redstone dust signals weakened by distance, delay a signal, and redirect a signal.

Placement
A redstone repeater can be attached to the top of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the redstone repeater will "pop" off as an item.
A redstone repeater is marked with an arrow pointing towards its front. The repeater only reacts to signals from the block behind it and only propagates signals to the block in front of it (in the direction of the arrow). It also has an adjustable delay that can be set from 1 to 4 ticks by right-clicking it.
Activation
A redstone repeater is turned ON by any powered component at its back and is unaffected by the powered state of any block beside, above, below, or in front of it (but see below about "locking" a repeater).
Effect
A powered redstone repeater turns ON redstone dust or a mechanism component in front of it, or strongly powers an opaque block in front of it. It has no effect on the blocks under, above, beside, or behind it.
A redstone repeater not only "repeats" a signal (strengthens it for further transmission), it also delays it by 1 to 4 ticks. A redstone repeater will also increase the duration of any pulse shorter than its delay to match the duration of its delay.
A redstone repeater can be "locked" by powering it from the side with another redstone repeater or with a redstone comparator. A locked repeater will not change its output state until unlocked, even if its input changes. A repeater locked by another repeater (but not by a comparator) will display its locked status with a bedrock bar.

Mechanism components

Mechanism components are blocks which react to redstone power by affecting the environment ⃢₀ₓ by moving themselves or other entities, by producing light, sound, or explosions, etc.

Activating a mechanism component (in this case, a redstone lamp)
Activation
Mechanism components are turned ON by:
  • an adjacent active power component (Exceptions: a redstone torch will not turn ON a mechanism component it is attached to, and a piston is only activated by a power component directly in front of it if the component is connected to it.)
  • an adjacent powered opaque block (strongly-powered or weakly-powered)
  • a powered redstone repeater or redstone comparator facing the mechanism component
  • powered redstone dust configured to point towards the mechanism component (or on top of it, for opaque mechanism components); a mechanism component is not turned ON by adjacent powered redstone dust which is not configured to point towards it.
Activating a piston by quasi-connectivity ⃢₀ₓ Note that the piston on the left is not powered by quasi-connectivity because the redstone dust is running past the block above the piston, rather than directly into it, and thus would not power a mechanism there)
Quasi-Connectivity
In addition to the methods above, dispensers, droppers, and pistons Piston Transparency Yes Luminance None Blast resistance 2.5 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Drops Itself Data values See Data values Pistons are blocks capable of pushing most blocks, depending on minecraft can also be turned ON if a block above it receives a block update (including a redstone update within two blocks of the component) and is powered by any of the above means, even without a mechanism component (e.g.; even if the block above the component is air or a transparent block) . This rule is often simplified to say that the components can be powered by blocks diagonally above or two blocks above, however other methods of activation by connectivity exist (see image to the right). This method of activation is also known as "connectivity", "piston connectivity" (as it originated with pistons), or simply "indirect power".
Activated vs. Powered ⃢₀ₓ The top lamp is both activated (the lamp is on) and powered (it can power the repeater), while the bottom lamp is activated but not powered.
Activated vs. Powered
For opaque mechanism components (command blocks, droppers, dispensers, note blocks and redstone lamps), it`s important to make a distinction between a mechanism component being activated (so that it performs an action) and being powered (so that a redstone signal could be drawn from it by a transmission component). Any method of powering a mechanism component (such as a redstone torch underneath it) will also activate it, but some activation methods (such as a redstone torch next to or above a mechanism component) won`t actually power the component (following the usual rules for power components).

Activator rail

An activator rail is used to activate a minecart.

Placement
An activator rail can be attached to the top of any opaque When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with minecraft block, or to the top of an upside-down slab or upside-down stairs. If the attachment block is removed, the activator rail will pop off as an item.
When placed, an activator rail will configure itself to line up with adjacent rails, activator rails, powered rails, and detector rails, as well as such adjacent rails one block above. If there are two such adjacent rails not on opposite sides, or three or more such adjacent rails, an activator rail will line up in the east-west direction. If there are no such adjacent rails, an activator rail will line up in the north-south direction. An activator rail will slope upward to match with a rail above it (when there is more than one such rail, the order of preference is: west, east, south, and north). Other configurations can be created by placing and removing various rail.
Activation
In addition to the methods above, an activator rail can also be activated by an activator rail adjacent to it that is activated. Activator rail can transmit activation up to 9 rails (the first originally-activated activator rail, and up to eight additional activator rails). Activation transmitted in this way can only power activator rail.
Effect
An activator rail affects certain minecarts passing over it. The effects vary with the type of minecart activated:
  • A minecart with command block will execute its command every 2 redstone ticks (5 times per second).
  • A minecart with hopper will be deactivated by an activated activator rail (it will stop sucking up items in its path, or transferring items to containers as it passes them), and re-activated by an unactivated activator rail.
  • A minecart with TNT will be ignited by an active activator rail.
  • Regular minecarts with an entity riding it (mob or player) will eject that entity if the activator rail is active.
  • Other minecarts are not affected by an activator rail.

Command block

A command block is used to execute a server command. Command blocks can only be obtained with the command give minecraft:command_block .

Placement
After being placed, the player can set the command to be executed by right-clicking on the command block.
Effect
When activated, a command block executes its defined command once. To make a command block constantly execute its command, it must be run on a clock circuit.
Like other mechanism components, an already-activated command block will not respond to other redstone signals. To make a command block execute its defined command more than once it must be deactivated and re-activated repetitively.

Dispenser

A dispenser is used to automatically affect the environment by throwing items.

Activation
See Quasi-Connectivity above.
Effect
When activated, a dispenser ejects one item. If multiple slots are occupied by items, a random item is ejected.
If the dispenser is facing a container, the ejected item will be transferred into the container. Else, the effects of being activated vary with ejected item:
