Entity Library adds a simple in-game “library” screen that lets you browse and preview entities in 3D without actually summoning them into the world.
Built for modpacks where you want a quick way to check what mobs exist (including modded mobs) and what they look like, without spawning, ticking, or affecting gameplay.
Features
- Browse a searchable list of LivingEntity types registered by Minecraft and your mods
- 3D preview panel (no entity is spawned into the world)
- Shows the entity registry ID and a
/summon <id> ~ ~ ~ hint for reference
- Mouse wheel zoom (preview scale)
- Drag to rotate the preview
- Optional walk/idle animation toggle
- Favorites: star entities and filter to show only favorites (saved across sessions)
- Filters: All, Living, Hostile, Passive, Favorites
- Namespace/mod filter to show entities from a specific mod/namespace
- Detail panel with: display name, registry ID, max health, dimensions, mob category, and
/summon command with copy button
- Dark/Light theme toggle (saved to config)
- Optional NBT editor for common tags (NoAI, Glowing, Invulnerable, Silent, NoGravity, PersistenceRequired, CustomNameVisible) plus Custom Name, with live
/summon preview + copy
- Loot table / drops display (singleplayer only)
Controls
- Open the library: O (configurable in Minecraft Controls)
Compatibility
- Minecraft: 1.18.2
- Forge: 40.3.11+
- Client-side mod. Intended to be safe to use on servers (it does not summon anything), but servers may still require clients to follow their mod rules.
Notes / Limitations
- The list intentionally hides non-living entity types (projectiles, boats, minecarts, etc.).
- Some modded entities may fail to preview if they require server-only initialization or special spawn data; these will show a preview error instead of crashing the game.
- Loot table / drops display works in singleplayer only.
Modpack Permissions
- You may include this mod in modpacks.
