Minecraft Compendium

by Lasercraft32 · on Modrinth

Uses advancements to log information for the player. Look at mobs with your spyglass to add them to your Mobestiary, and discover biomes and structures!

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

IMPORTANT: This pack has a required resource pack! It won't work without it (be sure to click on the version's name intsead of just clicking "download" otherwise you'll miss it!)

This data pack adds a bunch of advancements to log information for the player. When you explore new biomes or structures, they will automatically be added to your advancements tab. It also adds a mobestiary that you can log info into by looking at mobs using a spyglass!

There are advancements for every single biome, structure, and mob in the game!

NOTE: This pack only includes vanilla mobs, biomes, and structures.
