About this Mod
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
- 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.
- 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
useLimitedHookgamerule 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
