Bell

"Ding dong, who's there? A RAID? GET INSIDE!!!"

- Adrian Östergård

A bell is a transparent animated block entity that produces a sound when.

Natural generation
Bells can generate naturally in all village variants, usually near the center of the village in the meeting point.

Obtaining
A bell requires a pickaxe to be mined or it drops nothing.

Bells cannot be crafted, only found or traded.

Trading
$$, apprentice-level armorer villagers have $1/3$ chance to sell a bell for 36 emeralds. Apprentice-level toolsmith villagers sell bells for 36 emeralds. Journeyman-level weaponsmith villagers sell bells for 36 emeralds.

$$, apprentice-level armorer villagers have a 50% chance to sell a bell for 36 emeralds. Apprentice-level toolsmith and weaponsmith villagers always offer to sell a bell for 36 emeralds.

Usage
When the side of a bell is, it produces a sound as well as a "swaying" animation. Bells can be rung using a redstone signal. $$, bells can also be rung by any damage-dealing projectile. $$, they can be rung by any projectile by right clicking. Bells can be anchored to the side of blocks, ceilings, and floors. Also, if the player the bell while villagers are sleeping, all of the villagers wake up. Bells can be rung only from certain angles; trying from an incorrect angle does not cause the bell to ring, but the hand still reaches out anyway.

When rung, villagers run into their houses immediately as they do at sunset. The bell's functional range for sending villagers to their home is 31x31 squared, with the bell counting as 1. This gives the bell an effective area of 961 blocks per plane and totals the bells effective area to 29792 blocks affected in the whole square. However, the audible range of the bell is shorter, and can only be heard from a maximum of 29x29 blocks away (although to achieve this full range, multiple bells are required).

Additionally $$, if a bell is rung and there is a raid mob within 32 blocks, the Glowing effect is applied to all raid mobs within 48 blocks, and particles appear. It produces a resonating sound once this process is complete.

Block entity
A bell has a block entity associated with it that holds additional data about the block.

Trivia

 * $$, bells formerly had unused data values with only a side texture that was required to ring the bell.
 * $$, bells deflect any projectile that does not disappear when hitting a surface (arrows or tridents).
 * Despite some villages generating with more than one bell, villagers need only one of them to meet and spawn iron golems.
