Create Grappling Hooks

A grappling hook movement add-on for Create: Aeronautics. Fire cables across the sky, swing between your airships like Spider-Man, ride cables on a trolley, and carry your friends along.

✨ Features

• Grapple Launcher — fire a cable between two points (works on terrain and moving physics ships/floors).
• Swing Hook — a swing-anywhere grappling hook. Fire it at any surface and swing from it like Spider-Man. Dual-wield one in each hand for the full tensed pose. Reel the rope in/out with Shift+W / Shift+S.
• Momentum-based release — the faster you swing, the farther you launch when you let go. Release with a click, Space, or Ctrl+Space.
• Rope that wraps around obstacles — your rope bends and curves around blocks and airship edges as you swing, instead of clipping through them.
• Cable Trolley — clip onto a cable and ride it, moving toward wherever you look.
• Hand-hold chain — right-click a riding player to grab their free hand and get carried along. The whole chain moves in perfect sync.
• Three ways to dismount — Shift to drop, Space to hop ~1 block toward your view, Ctrl + Space to launch ~3 blocks. Works for the rider and the carried player.
• Spinning rollers — the trolley's wheels roll as you slide along the cable.
• One trolley per rider — a connector can only be ridden by one player at a time.
• Custom model, texture & sound effects — fully redesigned guns, dart and connector.
• Shaderpack compatible (Iris / Oculus).
• Multiplayer ready — fully synced; others see you swing, hang, ride, get carried, and watch your rope wrap around obstacles in real time.

⚠️ Required versions — please read before installing!

This addon hooks directly into Create: Aeronautics' items and its native physics, so the versions must match. Using different ones can crash the game.

• Minecraft 1.21.1 + NeoForge
• Create 6.0.x (tested on 6.0.10)
• Create: Aeronautics 1.2.x — the create-aeronautics-bundled file (tested on 1.2.1)
• Sable 1.2.x — ships with Aeronautics (tested on 1.2.2)

This version now refuses to load with a clear message if it finds an incompatible Create: Aeronautics or Sable version, instead of crashing.

Game crashed / won't start after adding the mod?

It's almost always a version mismatch of Create: Aeronautics or Sable.

• ✅ Your world is NOT broken — the mod only crashes while loading it, and it never touches your saved world.
• To get back in: remove this mod from your mods folder, launch, and re-add it once your Create: Aeronautics + Sable versions match the list above.
• It's a native crash, so there's no normal crash report — if it keeps happening, send me the hs_err_pid####.log file from your game folder and I'll help.

🎮 How to use

1. Craft the Grapple Launcher, Swing Hook and Cable Trolley (recipes shown in JEI/EMI).
2. Swing Hook: right-click to fire (left-click for an off-hand second hook). Swing freely; Shift+W/S to reel up/down; click or Space / Ctrl+Space to let go (the faster you swing, the farther you fly).
3. Grapple Launcher: right-click two surfaces to span a cable.
4. Cable Trolley: hold it and right-click the cable to clip on and ride. Move with W/S toward where you look; Shift / Space / Ctrl+Space to get off.
5. Remove cables with the Create Wrench (Shift + right-click).

⚠️ Known issues (being worked on)

• The hook can still occasionally fly off when the rope wraps around an obstacle.
• The rope only wraps around one physics platform at a time — if it crosses several separate floating Aeronautics platforms, it wraps around just one.
• On fast-rotating platforms, the rope can be dragged along with the rotation.
