Do observers detect cauldrons?

Answered by Randy McIntyre

The Observer is a unique block in Minecraft that has the ability to detect changes in its surroundings and emit a redstone signal accordingly. It is commonly used in redstone contraptions and automation systems to detect various events and trigger different actions.

Now, when it comes to cauldrons, the Observer does have the ability to detect certain actions related to them. Specifically, it can detect attempts to add or remove water from a cauldron using specific items.

If a player tries to add water to a cauldron that is already full, the Observer will detect this action and emit a redstone signal. This means that if a player attempts to pour water from a water bucket, water bottle, splash water bottle, or lingering water bottle into a cauldron that is already filled with water, the Observer will pick up on this and trigger any connected redstone mechanisms.

Similarly, if a player tries to remove water from a cauldron using the same items mentioned above, the Observer will also detect this action. However, it’s important to note that the Observer will only detect water removal if the cauldron is not empty. If the cauldron is already empty and a player tries to remove water from it, the Observer will not register this action.

This functionality of the Observer can be quite useful in various situations. For example, you could set up a redstone contraption that triggers a mechanism whenever someone tries to add water to a full cauldron, effectively creating a warning system. On the other hand, you could also use it to detect when someone is trying to remove water from a cauldron, perhaps to trigger a hidden trap or secret door.

In my personal experience, I have used Observers in different redstone contraptions, including ones involving cauldrons. One particular instance was when I wanted to create a puzzle where players had to correctly fill a cauldron with water in order to access a hidden treasure. By using Observers, I was able to detect if they mistakenly tried to add water to an already full cauldron and provide feedback accordingly.

To summarize, the Observer in Minecraft can indeed detect certain actions related to cauldrons. It can detect attempts to add water to a cauldron that is already full, and also detect water removal from a cauldron if it is not empty. This functionality opens up various possibilities for redstone contraptions and automation systems in the game.
