What can observers detect?

Behavior. In Java Edition, an observer detects changes in its target's block states, or the breaking or placing of a block (i.e. changes in its block state, but not its block entity data). This means that changes like the age of crops can be detected because they are part of the block states.

Can an observer detect a hopper?

Do observers detect beds?

There just happens to be an entity on top of the block. So so the argument given Observers are designed to detect blockstate changes (such as a bed changing from empty to being used), there is currently a bug in the game that prevents observers from doing this is not valid because it rests on a false premise.

Can an observer detect a piston?

The observing facet of the block has a face texture on it. When it detects something, the block sends a Redstone signal to any Redstone component adjacent to it, like a Redstone lamp, piston etc. These blocks are usually used with a piston, activating the piston whenever they detect a change.

What does activator rail do in Minecraft?

Activator rails cause any minecart that runs over them to drop off any player or material that is being transported. Detector rails act as pressure plates, which can be used to create signals and other functions when minecarts pass over them. They can also be used to send a minecart from one detector rail to another.
