SIGNAL VINE TEXT UPDATE

When this happens, an observer emits a pulse after being pushed or pulled, but not beforehand.

SIGNAL VINE TEXT UPDATE

It also counts as a block update when the observer itself is moved by a piston. Its timing can also be incorrect due to MCPE-73342. In Bedrock Edition, it is supposed to be delayed by 1 tick as well but is actually delayed 2 redstone ticks due to 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. In Java Edition, the pulse is emitted with a delay of 1 redstone tick. The pulse can power redstone dust, a redstone comparator, a redstone repeater, or any mechanism component located at its opposite end. When it detects something, the observer emits a redstone pulse of strong power at level 15 for 2 game ticks (1 redstone tick). As a result, each can detect some kinds of changes that the other cannot. The causes and propagation of block updates are different between Java Edition and Bedrock Edition. In Bedrock Edition, an observer acts as a block update detector and detects anything that causes a block update. This means that changes like the age of crops can be detected because they are part of the block states. changes in its block state, but not its block entity data). In Java Edition, an observer detects changes in its target's block states, or the breaking or placing of a block (i.e. 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. The texture of the detecting side is that of an observing face. It observes the block that it is placed against.

An observer is placed similarly to a piston.
