{{ | {{MC/In|java}}, an observer detects [[Minecraft:Block update#Post placement update|shape updates]] coming from the block it's facing. This can involve changes in block states (like crops growing, for example), or the breaking or placing of a block. This makes observers differ from block update detectors in terms of what they can detect.{{only|JE|short=1}} | ||
{{ | {{MC/In|bedrock}}, an observer acts as a block update detector and detects anything that causes a block update. | ||
The causes and propagation of block updates are different between ''Java Edition'' and ''Bedrock Edition''. As a result, each can detect some kinds of changes that the other cannot. See the table below for a comparison. | The causes and propagation of block updates are different between ''Java Edition'' and ''Bedrock Edition''.

In ''Java Edition'', the pulse is emitted with a delay of 2 game ticks. In ''Bedrock Edition'', it is delayed by 2 game ticks as well, but it's sometimes delayed by 4 or 6 game ticks due to {{bug|MCPE-15793}}, a bug causing redstone delays to be incorrect when components are activated by world changes (which, in the case of the observer in ''Bedrock Edition'', is the only way it can be activated), as opposed to pure redstone components ticking.

For coral, the death also happens too fast for the observer to detect it separate from the placement or water removal, but a non-waterlogged coral can be placed using commands. Coral blocks take multiple seconds to die, and removing water next to the coral block does not activate the observer anyway, so they can be detected under normal circumstances.</ref> | ||

For the {{{Description}}} of the same name, see [[{{{Destination}}}]]. |
Template:Infobox block An observer is a Minecraft:block that emits a quick Minecraft:redstone pulse from its back whenever its "face" detects that the Minecraft:block, Minecraft:fluid, or Minecraft:air directly in front of it has changed.
Obtaining
Breaking
An observer requires a Minecraft:pickaxe to be mined. When mined without a pickaxe, it drops nothing. Script error: No such module "breaking row".
Crafting
Usage
An observer is placed similarly to a Minecraft:piston. It observes the block that it is placed against. The texture of the detecting side is that of an observing face. As observers can detect the state of other observers, placing two adjacent observers, each watching the other, can make a fast and compact redstone clock. They send out a redstone pulse.
Behavior
in Template:Editions, an observer detects shape updates coming from the block it's facing. This can involve changes in block states (like crops growing, for example), or the breaking or placing of a block. This makes observers differ from block update detectors in terms of what they can detect.Template:Only
in Template:Editions, an observer acts as a block update detector and detects anything that causes a block update.
The causes and propagation of block updates are different between Java Edition and Bedrock Edition. As a result, each can detect some kinds of changes that the other cannot. See the table below for a comparison.
When it detects something, the observer emits a redstone pulse of strong power at signal strength 15 for 2 game ticks. The pulse can power redstone dust, a redstone comparator, a redstone repeater, or any mechanism component located at its opposite end.
In Java Edition, the pulse is emitted with a delay of 2 game ticks. In Bedrock Edition, it is delayed by 2 game ticks as well, but it's sometimes delayed by 4 or 6 game ticks due to Template:Bug, a bug causing redstone delays to be incorrect when components are activated by world changes (which, in the case of the observer in Bedrock Edition, is the only way it can be activated), as opposed to pure redstone components ticking. Its timing can also be incorrect due to Template:Bug.
Observers also emit a pulse after getting moved by pistons: this enables them to be used in flying machines. in Template:Editions, however, moving an observer that is currently emitting a redstone signal will cause it to turn off instead.
Because observers in Java Edition react to shape updates, they can detect some changes that a block update detector (BUD) would be unresponsive to, as opposed to Bedrock Edition where observers detect the exact same updates that any other BUD would detect.
Observers are visually opaque and non-conductive: they block light and allow mob spawning on top, do not cut off redstone wire, and cannot conduct redstone power. in Template:Editions, they also allow opening chests below and prevent redstone wire placed on it from transmitting a signal downward.

Template:Redr Minecraft:Coral/coral block/coral fan converting into dead coral/dead coral block/dead coral fan. |
Template:Redr<ref>in Template:Editions, the death of a coral fan cannot happen under normal circumstances — it happens the next tick after the coral fan is placed, so the observer has already read the placement or water removal update, and coral fans placed using commands are waterlogged — but if lag is used to make the unwaterlogging and death events happen separately, the observer detects both. For coral, the death also happens too fast for the observer to detect it separate from the placement or water removal, but a non-waterlogged coral can be placed using commands. Coral blocks take multiple seconds to die, and removing water next to the coral block does not activate the observer anyway, so they can be detected under normal circumstances.</ref> |
