Vibration

This article is a work in progress.

 

Please help expand and improve it. The talk page may contain suggestions.

Vibrations are a mechanic based around the concept of sound and its physical interactions. Most in-game actions and events produce vibrations of different frequencies, or intensity. Wool can be used to dampen or block vibrations and prevent them from traveling if collided with. Vibrations are solely utilized by sculk sensors, sculk shriekers, wardens, and allays.

Mechanics

When a vibration is created, it takes the appearance of blue-cyan "sound wave" particles which moves from its source of origin to the entity which detected it. Vibration waves move at a constant speed, and their speed cannot be altered.

Vibration frequency

Instructions: Bedrock Edition values

Each vibration in the game falls under a certain frequency value. This value can be measured with a comparator. With the right contraption utilizing a calibrated sculk sensor, the player could detect if a certain action has occurred or is occurring nearby.

Sources which are not detected

The following occurrences, despite presumably causing physical motion, do not produce vibrations and therefore cannot be detected:

• Blocks destroyed by a fluid flowing into their space^[1]
• Several blocks being destroyed due to their supporting block being removed:^[2]
  • Rails
  • Powered rails
  • Detector rails
  • Activator rails
  • Redstone wire
  • Redstone repeaters
  • Redstone comparators
• Several cases where a dispenser fails to perform an action:^[3]
  • Flint and steel not creating fire
  • Bone meal not growing something
  • Heads and carved pumpkins, if not equipped on something or placed
  • Shulker boxes, if not placed
  • Shears, if there's nothing to shear
  • Glowstone, if it doesn't charge a respawn anchor
• Inserting an eye of ender into an end portal frame^[4][5]
• Eyes of ender breaking^[6]
• Silverfish entering blocks^[7]
• Water and lava flowing into existing spaces, or drying up^[8]
• Changing the mode of a redstone comparator^[9]
• Changing the delay on a redstone repeater^[10]
• Changing the shape of a single unit of redstone wire^[11]
• Fire extinguished by rain^[12]

The following cases have been confirmed to be intentional:

• Axolotls being bred via tropical fish buckets^[13]
• Moss blocks replacing existing blocks^[14]

Amethyst resonation

When a block of amethyst is placed adjacent to a sculk sensor or a calibrated sculk sensor, if that sculk sensor receives a vibration, the block of amethyst re-emits its frequency as a separate vibration at its location. This vibration can then be detected by another sculk sensor, allowing a chain of sculk sensors and amethyst blocks to be created, transmitting a signal wirelessly.

Vibration occlusion

Wool can be used to block vibrations from reaching nearby sculk sensors. If a wool block is placed between a sensor and a vibration source, the sensor is not able to detect vibrations behind it. Similarly, if a wool block is placed between a sensor and a sculk shrieker, the sensor is unable to alert the shrieker.

Sculk sensors are not able to detect the placing and breaking of wool, as well as entities walking, sprinting, or jumping on top of it. They are also unable to detect items dropped on wool, or wool itself dropped in item form.

Similar to sculk sensors, wardens are also unable to detect everything wool-related as listed above.

Wool can also be used to block note block sounds from reaching allays.
