Grappsling (Grapple Sling) is a datapack that adds a grapple hook with semi-accurate physics.

The grapple hook will pull you until you are at a reasonable distance, then you will transition to swinging :D

This idea was suggested by: https://www.planetminecraft.com/member/imalittlhigh/ in the forum post: https://www.planetminecraft.com/forums/minecraft/datapacks/i-need-difficult-ideas-to-create-for-datapacks-670676/

HOW TO GET GRAPPLE HOOKS:
Run in chat with commands on: /function type:grapplehook


Or you can use the recipe:


SHIFT TO CUT ROPE (DISCONNECT HOOK)

Enjoy the grappling hooks!

(Warning: while it works in multiplayer, you might disconnect other people's hooks when shifting.)
Feedback would be appreciated.
