Puzzles Lib FAQ
10 questions players actually ask, answered.
what does puzzles lib mod actually do?
Puzzles Lib is a library mod, so it doesn't add any blocks, items, or gameplay on its own. It provides shared code and an abstraction layer that other mods use to run on both Forge and Fabric, which is why you only ever install it as a dependency.
do i need to install puzzles lib on both client and server?
Yes, install it on both the client and the server. Since it's a dependency for other mods, the game will refuse to launch or the server will reject the connection if it's missing on either side.
how do i know if puzzles lib is working?
You won't see it in-game because it adds no content of its own. The real test is whether the mods that depend on it load and function correctly; if they do, Puzzles Lib is doing its job.
puzzles lib is crashing my game, what do i do?
Puzzles Lib itself rarely crashes on its own; the crash is almost always caused by a dependent mod or a version mismatch. Check that Puzzles Lib matches the Minecraft version and loader of the mods requiring it, and remove or update any mod that's out of sync.
can i use puzzles lib without any other mods?
You can install it alone, but it will do nothing visible. It's designed to sit quietly in the background and only becomes useful when another mod depends on it.
which mods need puzzles lib?
It's most commonly required by mods from the same ecosystem that share its frameworks, such as certain mob, structure, or utility mods. If a mod lists Puzzles Lib as a dependency, install it alongside that mod.
does puzzles lib affect performance?
It's lightweight and adds no world content, so its own performance impact is negligible. Any lag you notice will come from the mods using it, not from Puzzles Lib itself.
why does a mod say it needs puzzles lib but i can't find it?
Make sure you're searching for the exact name and that you're on the correct mod loader and Minecraft version. If it still doesn't appear, the dependent mod may require a specific build that isn't showing in your current search filters.
can i remove puzzles lib if i don't think i'm using it?
Don't remove it unless you've also removed every mod that depends on it. Deleting it while dependent mods are still installed will cause those mods to fail to load or crash the game.
is puzzles lib compatible with other library mods?
Yes, it's designed to coexist with other libraries and doesn't conflict with them. Problems usually only arise from version mismatches between Puzzles Lib and the mods that require it.
