Block4Block Datapack
Java data pack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on Modrinth
Block4Block introduces a unique mechanic where you need a block to break a block, changing how you gather resources and survive.
Here's what sets it apart:
- Unique Resource Gathering: Breaking blocks now costs a block.
- Land Claims: Players use lecterns and books to establish land claims.
- Claims can trade hands. Protect them.
- Vanilla Integration: It aims to improve the vanilla Minecraft experience subtly, with in-universe implementations rather than relying on commands or menus.
- Technical Farms & Inventions: It enables new and interesting farm designs and inventions.
Note: It requires both a plugin and a datapack to function correctly.
Open Source and made to be customizable for hosts to create the experience they want.
