Need Help - Grappling Whip

Hello there, new to this site and MCreator, but willing and wanting to learn.

Currently I wish to create a mod where you have whips, which are not just weapons but also serve as grappling hooks to attach to blocks or draw mobs near.
I have an item created, but I need help in figuring out what procedures I need to use to make the whip serve as a grappling hook:

1. When you right click it, a 3D like rope/chain extends 8 blocks out from the player. (I'm guessing I need to make that a separate texture.)
2. When the rope/chain hits a block, it will stick to it and the player will start swinging.
3. WASD would control which direction the player swings, SPACE and SHIFT would control the length of the rope/chain, allowing the player to rise or lower themselves, and pressing right click again will detach the rope/chain from the block.
4. If you were to grapple onto a mob, the player would then right click again and it would pull that mob toward the player.

Is there anyone who could give a step by step of sorts on which parameters or coding I would need to do to get that to work? I would greatly appreciate it.

Thank you in advance,
