Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This datapack lets boats and minecarts climb stairs. This will transport all minecart types and all mobs that are in the boats as well. Chest boats are now compatible!
This pack is used to make boats travel up ice blocks as seen in ice boat racing videos! Buttery smooth motion!
Watch this video for the How to Use
Place it in your datapacks folder, and have fun! 100% multiplayer compatible!
