For more information about placement on transparent blocks, see [[Opacity/Placement]].\n\nThe redstone comparator has a front and a back \u2014 the arrow on the top of the comparator points to the front. When placed, the comparator faces away from the player. The comparator has two miniature redstone torches at the back and one at the front. The back torches turn on when the comparator's output is greater than zero (the arrow on top also turns red). The front torch has two states that can be toggled by {{control|using}} the comparator:\n* Down and unpowered (indicating the comparator is in \"comparison mode\")\n* Up and powered (indicating the comparator is in \"subtraction mode\")\n\nThe redstone comparator can take a signal strength input from its rear as well as from both sides. Side inputs are accepted only from [[redstone dust]], [[Block of Redstone|redstone blocks]], [[redstone repeater]]s and other comparators. The redstone comparator's front is its output.\n\nIt takes 1 [[redstone tick]] (2 game ticks, or 0.1 seconds barring lag) for signals to move through a redstone comparator, either from the rear or from the sides. This applies to changing signal strengths as well as simply to turning on and off. Redstone comparators usually do not respond to 1-tick fluctuations of power or signal strength \u2014 for example, a [[clock circuit|1-clock]] input is treated as always off from the side, and always on from the rear.\n\nThe redstone comparator has four functions: maintain signal strength, compare signal strength, subtract signal strength, and measure certain block states (primarily the fullness of containers).\n\n=== Maintain signal strength ===\n\nA redstone comparator with no powered sides outputs the same signal strength as its rear input.\n\n=== Compare signal strength ===\n\n[[File:Comparators Explained.png|Comparators in comparison mode.|thumb]]\nA redstone comparator in comparison mode (front torch down and unpowered) compares its rear input to its two side inputs. If either side input is greater than the rear input, the comparator output turns off. If neither side input is greater than the rear input, the comparator outputs the same signal strength as its rear input.\n\nFormula: '''''Output''' = '''Rear''' \u00d7 ('''Left''' <= '''Rear''' AND '''Right''' <= '''Rear''')''\n{{-}}\n\n=== Subtract signal strength ===\n\nA redstone comparator in subtraction mode (front torch up and powered) subtracts the signal strength of the higher side input from the signal strength of the rear input.\n\nFormula: '''''Output''' = max('''Rear''' - max('''Left''', '''Right'''), 0)''\n\nFor example: if the signal strength is 6 at the left input, 7 at the right input and 4 at the rear, the output signal has a strength of ''max(4 - max(6, 7), 0) = max(4-7, 0) = max(-3, 0) = 0''.\n\nIf the signal strength is 9 at the rear, 2 at the right input and 5 at the left input, the output signal has a strength of ''max(9 - max(2, 5), 0) = max(9-5, 0) = 4''.\n\n=== Measure block state ===\n\n{{Schematic | caption = A redstone comparator can measure the fullness of a chest, as well as other block states, even through a block.\n |rd-ew!|rc-w!|ch|SB|rc-e!|rd-ew!\n}}\nA redstone comparator treats certain blocks behind it as power sources and output a signal strength proportional to the block's state. The comparator may be separated from the measured block by a solid block. However, {{in|je}}[[Category:Java Edition specific information]], if the solid block is powered to signal strength 15, then the comparator outputs 15 no matter the fullness of the container.<ref>{{bug|MC-64394}} (resolved as \"Works As Intended\")</ref>\n{{-}}\n\n==== Containers ====\n\n{| class=\"wikitable floatright\" style=\"margin-left: 0.5em; margin-right: 0; text-align: center;\"\n|+ Minimum Items for Container Signal Strength\n|-\n!Containers\n!{{BlockSprite|Furnace|link=Furnace}}<br>{{BlockSprite|Blast Furnace|link=Blast Furnace}}<br>{{BlockSprite|Smoker|link=Smoker}}\n!{{BlockSprite|Hopper|link=Hopper}}<br>{{EntitySprite|Minecart with Hopper|link=Minecart with Hopper}}<br>{{BlockSprite|Brewing Stand|link=Brewing Stand}}\n!{{BlockSprite|Dispenser|link=Dispenser}}<br>{{BlockSprite|Dropper|link=Dropper}}\n!{{BlockSprite|Chest|link=Chest}}<br>{{EntitySprite|Minecart with Chest|link=Minecart with Chest}}<br>{{BlockSprite|Shulker Box|link=Shulker Box}}<br>{{BlockSprite|Barrel|link=Barrel}}\n![[Double Chest|{{Schematic|size=16|ch-s|-|ch-n}}\n]]\n!{{BlockSprite|Jukebox|link=Jukebox}}\n|-\n!Total Number of Slots\n!3!!5!!9!!27!!54!!1\n|-\n!Power Level\n! colspan=\"5\" |Number of Items\n!Music Disc\n|-\n|0||0||0||0||0||0||No music disc inserted\n|-\n|1||1||1||1||1||1||\"13\"\n|-\n|2||14||23||42||1s<br>60||3s<br>55||\"cat\"\n|-\n|3||28||46||1s<br>19||3s<br>55||7s<br>46||\"blocks\"\n|-\n|4||42||1s<br>5||1s<br>60||5s<br>51||11s<br>37||\"chirp\"\n|-\n|5||55||1s<br>28||2s<br>37||7s<br>46||15s<br>28||\"far\"\n|-\n|6||1s<br>5||1s<br>51||3s<br>14||9s<br>42||19s<br>19||\"mall\"\n|-\n|7||1s<br>19||2s<br>10||3s<br>55||11s<br>37||23s<br>10||\"mellohi\"\n|-\n|8||1s<br>32||2s<br>32||4s<br>32||13s<br>32||27s||\"stal\"\n|-\n|9||1s<br>46||2s<br>55||5s<br>10||15s<br>28||30s<br>55||\"strad\"\n|-\n|10||1s<br>60||3s<br>14||5s<br>51||17s<br>23||34s<br>46||\"ward\"\n|-\n|11||2s<br>10||3s<br>37||6s<br>28||19s<br>19||38s<br>37||\"11\"\n|-\n|12||2s<br>23||3s<br>60||7s<br>5||21s<br>14||42s<br>28||\"wait\"\n|-\n|13||2s<br>37||4s<br>19||7s<br>46||23s<br>10||46s<br>19||\"Pigstep\"\n|-\n|14||2s<br>51||4s<br>42||8s<br>23||25s<br>5||50s<br>10||\u2014\n|-\n|15||3s||5s||9s||27s||54s||\u2014\n|}\nUsing a redstone comparator to measure the state of a container will output a signal strength in proportion to how full the container is (0 for empty, 15 for full, etc.).\n\nContainers that can be measured by a comparator include:\n* {{BlockLink|Furnace}}\n* {{BlockLink|Blast Furnace}}\n* {{BlockLink|Smoker}}\n* {{BlockLink|Brewing Stand}}\n* {{BlockLink|Hopper}}\n* {{ItemLink|Minecart with Hopper}} on top of a [[detector rail]]\n* {{BlockLink|Dispenser}}\n* {{BlockLink|Dropper}}\n* {{BlockLink|Chest}}\n* {{BlockLink|Trapped Chest}}\n* {{ItemLink|Minecart with Chest}} on top of a [[detector rail]]\n* {{BlockLink|Barrel}}\n* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large chest\n* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large trapped chest\n* {{BlockLink|Shulker Box}} (any color)\n\nGenerally speaking, the comparator output signal strength represents the average fullness of the slots, based on how many of that item form a full stack (64, 16, or 1 for non-stackable items).\n\nThe ''Minimum Items for Container Signal Strength'' table (right) shows the minimum number of 64-stackable items required to produce the different signal strengths from each type of container. Numbers followed by an \"s\" indicate the number of normal 64-stack equivalents (\"s\"), and additional items less than a stack required. For items that stack in 16 maximum ([[snowball]]s, [[sign]]s, [[ender pearl]]s, etc.), normal value must be divided by 4, each unity is equal to 4. Example: 3 ender pearls *4 = 12 normal stackable items. Each non-stackable item counts as one full-stack(64).\n\nFor example, to produce a signal strength of 10 from a hopper requires the equivalent of 3 full stacks plus 14 more items, or 206 items total, assuming they all stack in 64.\n\nWhen a comparator measures a large chest or large trapped chest, it measures the entire large chest (54 slots), not just the half directly behind the comparator. A chest or trapped chest that cannot be opened (either because it has an opaque block, [[ocelot]], or [[cat]] above it) always produces an output of 0 no matter how many items are in the container \u2014 shulker boxes can always be measured, even if they cannot open.\n\n;Calculating signal strength from items\n\n:When a container is empty, the output is off.\n\n:When it is not empty, the output signal strength is calculated as follows:\n\n:<code>signal strength = floor(1 + ((sum of all slots' fullnesses) / (number of slots in container)) * 14)</code>\n\n:<code>fullness of a slot = (number of items in slot) / (max stack size for this type of item)</code>\n\n:''Example:'' 300 blocks in a dispenser (which has 9 slots), where each block stacks to a maximum of 64, produces output with a signal strength of 8:\n<blockquote>\n1 + ((300 items / 64 items per slot) / 9 slots) * 14 = 8.292, floored is 8\n</blockquote>\n\n:Note that a non-stackable item is counted as a full slot (1 item in a slot, with a max stack size of 1: 1 / 1 = 1.0), and items that stack up to 16 (such as ender pearls, snowballs and eggs) are similarly considered a full slot at 16.\n\n;Calculating items from signal strength\n\n:It can be useful in redstone circuits to use containers with comparators to create signals of a specific strength. The number of items required in a container to produce a signal of desired strength is calculated as follows:\n\n:<code>items required = max(desired signal strength, roundup((total slots in container * 64 / 14) * (desired signal strength - 1) ) )</code>\n\n:''Example:'' To use a furnace (which has 3 slots) to create a strength 9 signal, players need 110 items:\n<blockquote>\nmax(9, (3*64/14)*(9-1)) = 109.714, rounded up is 110\n</blockquote>\n{{-}}\n\n==== Miscellaneous ====\n\n[[File:Comparator storage.png|Comparators used to measure containers.|thumb]]\nSome non-container blocks can also be measured by a redstone comparator:\n\n;{{BlockLink|Beehive}} and {{BlockLink|Bee nest}}\n\n: A hive or nest outputs a signal strength equal to the amount of honey in the hive/nest.\n\n;{{BlockLink|Cake}}\n\n: A cake outputs a signal strength relative to the amount of cake remaining.  Each slice is worth 2 signal strength, with 7 total slices, for an output of 14 for a full cake.\n\n[[File:Cauldron Redstone Strength Values.png|Cauldron signal strength|thumb]]\n;{{BlockLink|Cauldron}}\n\n: A cauldron outputs different signal strengths depending on how much water is inside. From completely empty to completely full, the output values are 0, 1, 2, and 3. If lava is inside, the strength is always 1{{upcoming|Java 1.17}} or 3{{only|be}}\n\n[[File:Composter Redstone Strength Values.png|Composter signal strength|thumb]]\n;{{BlockLink|Composter}}\n\n: A composter outputs different signal strengths depending on the level inside. From completely empty to completely full, the output values are 0, 1, 2, 3, 4, 5, 6, 7 and 8.\n\n;{{Anchor|CommandBlock}}{{BlockLink|Command Block}}\n\n: A command block stores the \"success count\" of the last command executed, which represents the number of times the most recently used command of this command block succeeded. A \"success\" is defined by the [[command]]'s success conditions: if a red error message is returned in the chat, the command was not successful.\n\n: Most commands can succeed once per execution, but certain commands (such as those that accept players as arguments) can succeed multiple times, and the comparator outputs the number of times it succeeded (maximum 15 when sent to redstone dust, but in the code is able to go up to 32-bit integer limit, and can be used in contraptions with no redstone dust with those values).\n\n: A command block continues to store the success count of the last command executed until it executes its command again, thus the comparator continues to output the same signal strength even after the command block is no longer being activated (it doesn't turn off when the signal to the command block turns off).\n\n;{{BlockLink|Daylight Sensor}}\n\n: A Daylight Sensor outputs a signal strength that varies with the time of day (or time of night if inverted).\n\n;{{BlockLink|End Portal Frame}}\n\n: An end portal frame outputs a full signal of 15 if it contains an [[eye of ender]] and zero otherwise.\n\n[[File:Item frame and comparator.png|A comparator can measure the presence and rotation of an item frame's contents.|thumb]]\n\n;{{EntityLink|Item Frame}}\n\n: A comparator can measure the state of an [[item frame]]'s contents. An item frame comparator outputs 0 if the item frame is empty, or 1 to 8 for any item depending on its rotation: 1 at initial placement, plus 1 for each 45\u00b0 of rotation for a maximum of 8.\n\n: For an item frame that holds a map, a unit of rotation is 90\u00b0 instead of 45\u00b0, but a comparator still outputs power levels 1 to 8. It takes two full rotations to cycle through all comparator outputs, and each orientation of the map corresponds to two output levels that differ by 4.\n\n: The comparator must be placed behind the block the item frame is attached to, facing away from the item frame. The block must be a full block, and the item frame cannot be submerged in water. Having a sign in the same block as the item frame will prevent the frame from sending a signal as well.{{only|java}}\n\n;{{BlockLink|Jukebox}}\n\n: A jukebox outputs a signal strength indicating which music disc is currently playing. See the ''Minimum Items for Container Signal Strength'' table above.\n\n;{{BlockLink|Lectern}}\n\n: A lectern outputs a signal strength that depends on what page the player is currently on (e.g. a book with 15 pages powers 1 [[redstone]] level per page, or one with 5 pages emits 3 signal strength per page).\n\n;{{BlockLink|Respawn Anchor}}\n\n: A respawn anchor outputs a signal strength of 0, 3, 7, 11, or 15, depending on the \"charged\" value.\n\n;{{BlockLink|Sculk Sensor}} {{upcoming|java 1.17|bedrock 1.17}}\n\n: A sculk sensor outputs a signal strength depending on the type of vibration that is detected.\n\n;{{BlockLink|Target}}\n\n: A target outputs a signal strength depending on the accuracy of an arrow toward the center of the target.\n{{-}}\n\n== Sounds ==\n=== Generic ===\n{{Sound table/Block/Wood}}\n=== Unique ===\n{{edition|java}}:\n{{Sound table\n|sound=Click.ogg\n|subtitle=Comparator clicks\n|source=Blocks\n|description=Sound played when switching between comparison and subtraction modes\n|id=block.comparator.click\n|translationkey=subtitles.block.comparator.click\n|volume=0.25\n|0.55/0.5\n|distance=16\n|foot=1}}\n\n== Data values ==\n=== ID ===\n{{edition|java}}:\n{{ID table\n|showforms=y\n|generatetranslationkeys=java\n|displayname=Redstone Comparator\n|spritetype=block\n|nameid=comparator\n|foot=1}}\n{{ID table\n|displayname=Block entity\n|spritename=redstone-comparator\n|spritetype=block\n|nameid=comparator\n|foot=1}}\n\n{{edition|bedrock}}:\n{{ID table\n|firstcolumnname=Redstone Comparator\n|shownumericids=y\n|showforms=y\n|generatetranslationkeys=bedrock\n|displayname=Unpowered block\n|spritename=unpowered-comparator\n|spritetype=block\n|nameid=unpowered_comparator\n|id=149\n|form=block}}\n{{ID table\n|displayname=Powered block\n|spritename=powered-comparator\n|spritetype=block\n|nameid=powered_comparator\n|id=150\n|form=block}}\n{{ID table\n|displayname=Item\n|spritename=redstone-comparator\n|spritetype=item\n|nameid=comparator\n|id=404\n|form=item\n|foot=1}}\n{{ID table\n|notnamespaced=y\n|displayname=Block entity\n|spritename=redstone-comparator\n|spritetype=block\n|nameid=Comparator\n|foot=1}}\n\n=== Metadata ===\n{{see also|Data values}}\n{{IN|be}}, redstone comparators use the following data values:\n{{/DV}}\n\n=== Block states ===\n{{see also|Block states}}\n\n{{/BS}}\n\n=== Block data ===\n{{see also|Block entity format}}\n\nA redstone comparator has a block entity associated with it that holds additional data about the block.\n\n{{/BE}}\n\n== Video ==\n\n<div style=\"text-align:center\">{{yt|J7Z20Zzz3yU}}</div>\n\n== History ==\n{{info needed section|Did {{bug|MC-50242}} also affect comparators?}}\n''For a more in-depth breakdown of changes to repeater textures and models, including a set of renders for each state combination, see [[/Asset history]]''\n{{History|java}}\n{{History||November 24, 2012|link=none|[[Jeb]] stated that there may be a \"capacitor\" in [[Minecraft]].}}\n{{History||December 27, 2012|link={{tweet|Dinnerbone|284388625595125760}}|[[Dinnerbone]] released [http://imgur.com/a/FBKed pictures] of the first version of the \"comparator\", stating it was a replacement for the \"capacitor\" idea that has variable, alternate inputs.}}\n{{History||January 2, 2013|link={{tweet|Dinnerbone|286428595423965184}}|Dinnerbone released one more [http://dinnerbone.com/media/uploads/2013-01/screenshots/2013-01-02_12.06.47.png picture] of the comparator.

''Top Left:'' Redstone wire connects diagonally vertically through non-opaque blocks. ''Top Right:'' Redstone wire does ''not'' connect diagonally vertically through opaque blocks. ''Center:'' Redstone wire gets darker as its power level drops, to a maximum of 15 blocks from a power source.|thumb]]\nRedstone dust can be placed on [[opaque]] blocks as well as [[glowstone]], upside-down [[slab]]s, [[glass]], upside-down [[stairs]], and [[hopper]]s. It can also be placed on some transparent blocks; see [[Opacity/Placement]] for more information. It cannot be placed suspended in midair, even with commands, which is not unintentional.<ref>{{bug|MC-182709}}</ref>\n\nRedstone wire configures itself to point toward adjacent redstone [[Redstone components#Power components|power components]] and [[Redstone components#Transmission components|transmission component]] connection points. Redstone wire also configures itself to point toward adjacent redstone wire one block higher or lower \u2013 unless there is a solid opaque block above the lower redstone wire.\n\nIf there is only one such adjacent redstone component, redstone wire configures itself into a line pointing both at the neighbor and away from it. If there are two or more such adjacent redstone components, redstone wire connects them in the form of a line, an \"elbow\", a \"T\", or a cross as needed. If there are no such adjacent redstone components, redstone wire configures itself into a plus sign, which can provide power in all four directions.\n\n{{IN|bedrock}}, redstone wire automatically configures itself to point toward adjacent blocks or [[Redstone components#Mechanism components|mechanism components]]. {{IN|java}}, it does not. If such a configuration is desired, the other neighbors of the redstone wire must be arranged to create it, i.e the redstone dust must be placed in a way that it would be pointed at the block\u2019s location even if it were not there.\n\nWhen redstone wire is reconfigured after placement, it does not update other redstone components around it of the change unless that reconfiguration also includes a change in power level or another component provides an update. This can create situations where a mechanism component remains activated when it shouldn't, or vice versa, until it receives an update from something else \u2013 a \"feature\" of redstone wire that can be used to make a [[BUD|block update detector]].\n\n==== Behavior ====\n\n{{Schematic | caption =\n\n{{IN|be}}, the signal can go down from glass blocks.\n\n |||rd-$ew!|RL-!||||rd-$ew!|RL-!|-\n |rt-$!|rd-$ew!|SB|||rt-$!|rd-$ew!|glass||-\n |ts-$|SB|rd-$ew|RL||ts-$|SB|rd-$ew!|RL-!\n\n}}{{Schematic | caption =\n\nHowever, the signal can never go down from slabs.\n\n |||rd-$ew!|RL-!||||rd-$ew!|RL-!|-\n |rt-$!|rd-$ew!|SB|||rt-$!|rd-$ew!|glass||-\n |ts-$|ts-$|rd-$ew|RL||ts-$|ts-$|rd-$ew|RL\n\n}}\n\nRedstone wire can transmit power, which can be used to operate [[Redstone components#Mechanism components|mechanism components]] ([[door]]s, [[piston]]s, [[redstone lamp]]s, etc.).\nRedstone wire can be \"powered\" by a number of methods:\n* from an adjacent [[Redstone components#Power components|power component]] or a strongly-powered block\n* from the output of a redstone repeater or redstone comparator\n* from adjacent redstone wire. The powering dust can be a level higher or lower, but with restrictions:\n** Redstone dust can be powered by redstone dust that is one level lower, or on an [[opaque]] block one level higher. A transparent block cannot{{only|java}} pass power downward.\n** The block \"between\" the two dust blocks must be air or transparent. A solid block there \"cuts\" the connection between the higher and lower dust.\n\nThe \"power level\" of redstone dust can vary from 0 to 15. Most power components power-up adjacent redstone dust to power level 15, but a few ([[daylight sensor]]s, [[trapped chest]]s, and [[weighted pressure plate]]s) may create a lower power level. Redstone repeaters output power level 15 (when turned on), but [[redstone comparator]]s may output a lower power level.\n\n{{Schematic | caption =\n\nRedstone wire can transmit power up to 15 blocks.\n\n |rt-$!|rd-$!+15|rd-$!+14|rd-$!+13|rd-$!+12|rd-$!+11|rd-$!+10|rd-$!+9\n |rd-$!+8|rd-$!+7|rd-$!+6|rd-$!+5|rd-$!+4|rd-$!+3|rd-$!+2|rd-$!+1|rd-$+0\n\n}}\nPower level drops by 1 for every block of redstone wire it crosses. Thus, redstone wire can transmit power for no more than 15 blocks. To go further, the power level must be re-strengthened \u2013 typically with a redstone repeater.\n\nPowered redstone wire on top of, or pointing at, an opaque block provides ''weak'' power to the block. A weakly-powered block cannot power other adjacent redstone wire, but can still power redstone repeaters and comparators, and activate adjacent mechanism components. Transparent blocks cannot be powered.\n\nWhen redstone wire is unpowered, it appears dark red. When powered, it becomes bright red at power level 15, fading to darker shades with decreasing power. Powered redstone wire also produces \"dust\" [[particles]] of the same color.\n\nSince [[Java Edition 1.16]], while redstone wire always provides power to the directions it points into, it can still point into directions in which it cannot give power. If redstone wire comes in the from of a cross, the player can right-click to toggle it between a cross and dot. A redstone dot does not power anything adjacent to it, but powers the block under it.\n\n== Sounds ==\n{{Sound table/Block/Stone}}\n\n== Data values ==\n\n=== ID ===\n{{edition|java}}:\n{{ID table\n|firstcolumnname=Redstone Dust\n|showforms=y\n|generatetranslationkeys=java\n|displayname=Block\n|spritename=redstone-dust\n|spritetype=block\n|nameid=redstone_wire\n|form=block}}\n{{ID table\n|displayname=Item\n|spritename=redstone-dust\n|spritetype=item\n|nameid=redstone\n|form=item\n|foot=1}}\n\n{{edition|bedrock}}:\n{{ID table\n|firstcolumnname=Redstone Dust\n|shownumericids=y\n|showforms=y\n|generatetranslationkeys=bedrock\n|displayname=Block\n|spritename=redstone-dust\n|spritetype=block\n|nameid=redstone_wire\n|id=55\n|form=block}}\n{{ID table\n|displayname=Item\n|spritename=redstone-dust\n|spritetype=item\n|nameid=redstone\n|id=331\n|form=item\n|foot=1}}\n\n=== Metadata ===\n{{see also|Data values}}\n{{IN|be}}, redstone wire uses the following data values:\n\n{{/DV}}\n\n=== Block states ===\n{{see also|Block states}}\n\n{{/BS}}\n\n{{LoadPage|Redstone Dust/Asset history|List of block state combinations|h4}}\n\n== Achievements ==\n{{load achievements|Dispense With This}}\n\n== Video ==\n{{Video note|These videos do not show all uses for redstone in crafting and all methods of obtaining.
