Existed since 1.17, DropLadder is a datapack that lets you make easy Rope Ladders!

📜 Features:

• Make easy Rope Ladders:
  • Simply drop Ladder items towards a supported Ladder block!
  • Useful for neat builds, moving down quickly, measuring distances, or do some fun Redstone!
• Chainbreaking physics: Ladders break in a chain until the next attached Ladder!
  • Mainly because it makes sense.
• Works well with my other datapacks!
• Works in Multiplayer!
• Made and maintained with lots of care. Hope you enjoyed it!

🤔 It's not working, help!

• If you can't access in-game settings or debug commands, open to LAN and enable Allow Commands!
  • If you're in a Server, you'll need to /op yourself first!
  • Before 1.20.5, this option was called Allow Cheats.
• For any other problems, you can contact me personally here!
  • I'll personally respond to all help requests that's been sent here.
    Reply times may vary - there's just me working on all this, but I'll always help you out when I can.

🎉 Special Thanks:

Special thanks to these awesome people for keeping the lights on: If you like the effort that goes into making all this, help me keep the lights on so I get to do this more often!

📝 PS:

• Each version was designed and optimized for their respective Minecraft release, so you'll always get the best performance and features possible for the releases you're playing on.
  • I could make builds that supports multiple versions at once, but it also means adding extra stuff only to support game releases that it won't be run on. It just doesn't make sense to me.
• Due to Modrinth's limitations, this version is not the best of what I've got.
