About this Mod

Impulse Grapple

Turns fishing rods into grappling hooks with real motion, like in MineZ!

Simply cast your bobber onto a solid block, then reel it in to pull yourself with real motion and physics.

Grappling to a high platform across a gap.

Great for adventure maps, minigames, or survival worlds where you want more mobility for exploration.

Uses apply_impulse. Players must have an empty Saddle slot.
Pull strength scales with bobber distance.
Vanilla fishing and hooking mobs/items still work as normal.
Fully multiplayer compatible.
Made using Smithed Datapack Conventions to be highly compatible with other datapacks.

Feel free to use for custom maps, servers, and more!

Frequently Asked Questions

Impulse Grapple server crashes on startup – what to do?

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Impulse Grapple compatible with datapack and fabric and forge and neoforge and quilt?

Impulse Grapple officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Impulse Grapple – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Impulse Grapple consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
