Stretchy Leash

Makes leash breakages less likely when they can be avoided, and easier to detect when they do happen.

Changes

With the default configuration:

• Leashes don't immediately break past their maximum length, they will break only if they remain over-stretched for too long. This delay helps avoid breakage caused by tick lag or ping lag, where the player appears to teleport forward from the game's perspective.
• Leashed mobs are pulled in more strongly, so they can get back within range faster when over-stretching. Also reduces the risk of breakage when travelling at high speed.
• Leashed mobs have their step height increased to 1, making them less likely to get stuck when travelling on uneven terrains.
• Audio cues will play at the leader's position, whenever a leash starts to over-stretch, breaks, or is manually removed.

Config

The config for clients can be edited using Mod-Menu + Cloth-Config. On servers, use the /stretchy-leash config command (admin-only).

gracePeriod (Integer)

Default: 35 ticks (1.75s)
Vanilla: 0

Controls how long a leash can remain over-stretched without breaking.

maxLength (Double)

Default: 10 blocks
Vanilla: 10 blocks

Controls how far a leash can reach before starting to over-stretch.

This does not affect the distance at wich mobs start being pulled in (6 blocks).

pullStrength (Double)

Default: 2
Vanilla: 1

Controls how fast leashed mobs are pulled toward the leader.

stepHeight (Float)

Default: 1
Vanilla: 0

Increases the step-height of leashed mob to at least this value.

Caveats

In order to be fully server-side, the sound item.crossbow.load_middle is reused as the over-stretching cue. This sound event lacks a subtitle in vanilla, and would show an erroneous subtitle if it had one.
