Skybound is a grappling hook mod that works on moving objects. Throw a hook at a Create contraption, a Sable airship, or just a vanilla wall. The rope tracks it, wraps around it, and doesn't fall apart when the world moves under you.

Runs on both Fabric and NeoForge (1.21.1).

It's a fork of grapplemod-restitched, itself a Fabric port of Yyon's Grappling Hook Mod.

Why this fork exists

  1. Moving structures actually work. Grapple onto a flying Create Aeronautics airship, a Sable sublevel, or an assembled Create contraption. The rope tracks position, rotation, and sublevel splits.
  2. Multiplayer is stable. All hook and rope state lives on the server, so other players see what you see and nothing desyncs. Hooks survive a relog, too.

What's in the box

  • The classic Grappling Hook, with upgrades for motors, rockets, ender teleports, magnets, dual hooks, forcefields, and rope styles.
  • Long Fall Boots so your knees survive the descent.
  • Apply upgrades at any Smithing Table.
  • A few advancements, four built-in resource pack variants (classic textures, hook-only, no-enchants, classic recipes), and a useLimitedHook gamerule for servers that want to restrict where hooks can attach.

Compatibility

  • Create — grapple onto contraptions
  • Sable — grapple onto sublevels
  • Create: Aeronautics — rides on the Sable physics engine
