Leashable Players Mod

Leash other players with a lead. Runs on Fabric, NeoForge and Forge, plus a Bukkit/Spigot/Paper plugin build.

Setup

Drop the .jar for your loader into your mods folder:

• Fabric: leashmod-fabric-<version>.jar
• NeoForge: leashmod-neoforge-<version>.jar
• Forge: leashmod-forge-<version>.jar (1.20.1)

Server owners running Bukkit/Spigot/Paper/Purpur instead want leashmod-bukkit-<version>.jar in plugins/. One plugin jar covers 1.20.1 through 26.2.

If there is no release then please get a Jar from Modrinth.

Building

This is an Architectury multiloader project:

• common/ — shared logic and mixins (Mojang mappings)
• fabric/ — Fabric entrypoint + manifest
• neoforge/ — NeoForge entrypoint + manifest

Build every loader with ./gradlew build; the loader jars land in fabric/build/libs and neoforge/build/libs. gradle.properties pins one Minecraft version at a time — each target needs its own toolchain (26.x is unobfuscated and uses Loom's no-remap variant on JDK 25; 1.21.11 and 1.20.1 are obfuscated and use Mojang mappings on JDK 21 / 17), so switch it there and rebuild per version.

The bukkit/ plugin is a separate standalone Gradle build — cd bukkit && ./gradlew build.

Gamerules

Names are snake_case on 1.21.11 and newer, because game rules moved into a registry and were renamed to resource locations:

• leash_players_enabled (bool) — master switch
• leash_players_distance_min (int) — distance before knockback pull kicks in
• leash_players_distance_max (int) — distance before the leash snaps
• leash_players_allow_leashed_remove_fence_knot (bool) — may a leashed player remove fence knots

On 1.20.1 the same rules use the old camelCase names (leashPlayersEnabled, leashPlayersDistanceMin, leashPlayersDistanceMax, leashPlayersAllowLeashedRemoveFenceKnot).

The plugin has no game rules — plugins cannot register them. It reads the same four settings from plugins/LeashablePlayers/config.yml as enabled, distance-min, distance-max and allow-leashed-remove-fence-knot.

Incompatabilities

This mod does not work with Origins for some reason.
