Minecraft:Creaking Heart

Template:Infobox block A creaking heart is a living Minecraft:block<ref name="pale">Template:Citation</ref><ref name="snap">Template:Snap</ref> that can be Minecraft:crafted or found in Minecraft:pale oak trees in Minecraft:pale gardens. It activates if placed in a line between two Minecraft:pale oak logs; then, during nighttime, it spawns a Minecraft:creaking and protects it from all Minecraft:damage. Minecraft:Breaking a creaking heart that is protecting a creaking instantly kills it. Hitting a protected creaking causes Minecraft:resin clumps to grow on Minecraft:pale oak logs near its linked creaking heart.

Obtaining

Breaking

Creaking hearts drop as an item only when mined by a tool enchanted with Minecraft:Silk Touch. Otherwise, they drop 1–3 Minecraft:resin clumps; Minecraft:Fortune can increase the maximum drops by 1 per level (up to 6 with Fortune III).

Destroying a naturally-generated creaking heart also drops 20–24 Minecraft:experience, only in Minecraft:Survival mode.

Creaking heart has the highest Minecraft:hardness value of all blocks having the axe as the suitable tool.

Natural generation

Creaking hearts have a 10% chance to generate inside the top trunks of Minecraft:pale oak trees in the Minecraft:pale garden. They are always completely covered by other Minecraft:pale oak logs and are never exposed to the air. Pale oaks grown from Minecraft:pale oak saplings do not generate with hearts.

Usage

A creaking heart can be placed in different orientations, similar to Minecraft:logs. It has three states: uprooted, dormant, and awake. The creaking heart is uprooted by default, but it becomes dormant during the day and awake at night when placed between two Minecraft:pale oak logs, Minecraft:stripped pale oak logs, Minecraft:pale oak wood, or Minecraft:stripped pale oak wood with the same orientation. The texture of a creaking heart changes depending on its state, with the "core" appearing dark when uprooted, brighter when dormant and orange when awake. If the creaking heart hasn't already spawned a Minecraft:creaking, removing one of the surrounding aligned logs reverts it to the uprooted state.

Creaking hearts generate Minecraft:resin clumps on nearby pale oak logs when its linked creaking is attacked by a Minecraft:player or tamed Minecraft:wolf at night. There is a 5-second cooldown between each resin clump generation.

If a creaking heart is properly aligned between two pale oak logs and is located in the Minecraft:Overworld, it becomes awake at Minecraft:night (between 12600 and 23400 ticks). An awake creaking heart waits 2 Minecraft:ticks (0.1 seconds) and checks if the matching logs are in place. If so and it detects no linked creaking, it tries to find a valid location in a 33×17×33 box centered at that creaking heart to spawn one until successful, interrupted by getting destroyed or disabled. If found, it waits 20 ticks (1 second) before checking again if the matching logs are in place. If successful, it spawns a creaking after 2 extra ticks, otherwise it uproots. While a creaking heart is awake and has a linked creaking, it does not uproot until broken, even if any of the matching blocks are removed.

Creaking can spawn in yellow or brown regions when provided with a valid spawning space by a spawnable block placed in yellow or orange regions and three blocks of air above it.

Valid locations for creakings to spawn at follow these criteria:

The block below must have a solid top surface.
The block below is not Minecraft:leaves.
The location is any non-solid block. This means blocks like Minecraft:carpet can spawn-proof creakings, but not Minecraft:buttons.
The location is where there would be no Minecraft:liquid or other entities' Minecraft:hitboxes within a creaking's hitbox.

Minecraft:Creakings ignore solid blocks within its hitbox that are 2+ blocks above the ground while spawning.

Creaking hearts never spawn creakings in Minecraft:the Nether nor Minecraft:the End.

Despawning creakings

Breaking the heart kills its linked creaking and attributes the kill to the Minecraft:player who broke it, adding the kill to their Minecraft:statistics and triggering the Monster Hunter and Monsters Hunted Minecraft:advancements.

During daytime (starting at 23401 ticks), an awake creaking heart becomes dormant and despawns its linked creakings, unless it has been named using a Minecraft:name tag.

If the heart's linked creaking is too far away (more than 34 blocks away), that creaking despawns, and the heart spawns another one if conditions are met.

Redstone component

A Minecraft:redstone comparator connected to a creaking heart outputs a signal if the heart has a linked creaking. The strength of the signal depends on the Minecraft:Euclidean distance between the heart and its creaking, and is calculated as follows:

<math>\text{output} = 15 - \left\lfloor \frac{\text{distance}}{32} \times15 \right\rfloor</math>

In other words, the closer a creaking is to its heart, the stronger the signal.

Additionally, a creaking itself can be used to detect when a Minecraft:player is looking at it. An observed creaking sinks in Minecraft:water (or Minecraft:lava) instead of swimming upward, which can cause it to activate a Minecraft:pressure plate or similar means. An unobserved creaking bobs up and down in liquid, which can cause it to activate a pressure plate even if not being looked at. Giving a creaking enough space to bob prevents this.

Minecraft:Pistons of any kind cannot move creaking hearts.
