AlfinoLib Mod FAQ
10 questions players actually ask, answered.
Do I need to install AlfinoLib separately or does it come with other mods?
AlfinoLib is a library mod that must be installed separately in your mods folder. Many mods depend on it, but they won't include it—you need to add it yourself for those dependent mods to load.
What does it mean when a mod says it requires AlfinoLib?
The mod uses AlfinoLib's networking and data pack tools as a foundation. Without AlfinoLib installed, that mod won't start and you'll see an error in your launcher log.
Can I use AlfinoLib mods on both Forge and NeoForge?
Yes—AlfinoLib is designed to work across both Forge 1.20.1 and NeoForge 1.21.1, so dependent mods built on it will run on either loader as long as you match the version.
Why do I get a crash when I load a mod that needs AlfinoLib?
The most common cause is AlfinoLib not being installed. Check your mods folder to confirm it's there, and verify the mod version matches your game version and loader.
Does AlfinoLib add any items, blocks, or content to the game?
No—AlfinoLib is a library mod with no gameplay content. It only provides backend tools for networking and data packs that other mods use.
How do I know which version of AlfinoLib to download?
Download the version that matches your game version and mod loader (Forge 1.20.1 or NeoForge 1.21.1). Check the mod page for dependent mods to see which AlfinoLib version they require.
Will AlfinoLib cause lag or performance issues?
AlfinoLib itself is lightweight and runs in the background. Performance impact depends on how many dependent mods you have installed and how heavily they use the networking features.
Can I use AlfinoLib mods in a multiplayer server?
Yes—AlfinoLib handles client-server networking, so dependent mods will sync correctly between players. Install AlfinoLib on both the server and client.
What's the difference between AlfinoLib's networking and data pack features?
Networking handles real-time communication between client and server for mod features, while data pack tools let mods add content through data-driven systems. AlfinoLib unifies both into one library.
Do I need to configure AlfinoLib after installing it?
No—AlfinoLib requires no configuration. Just place it in your mods folder and it will work automatically for any dependent mods that need it.
