SlotLock
A simple client-side mod that let you lock your slots.
Quick answer
Which SlotLock release should I use?
Slotlock 1.1.1-BETA targets 1.19.2 with Fabric. The project page does not say whether it belongs on the client. The project page does not say whether it belongs on the dedicated server. 2 required mods need a matching file.
Where it goes
Is SlotLock required on the client, server, or both?
The project page does not say whether it belongs on the client. The project page does not say whether it belongs on the dedicated server.
The source does not explicitly classify this release as client-only or server-only.
What else does Slotlock 1.1.1-BETA need?
Slotlock 1.1.1-BETA. Change the file and its required mods may change too.
Install Fabric API, Fabric API first, but 2 required mods have no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does SlotLock add?

SlotLock
How it works:
The mod itself it's pretty simple, you only need to place your mouse above the slot you want to lock and press the slotlock keybind (Left Alt by default) and that's it. Locked slots cancel every keypress that tries to interact with it, so you can't accidentally throw an item you need in the trash, or store something in a chest you'll need later, or drop items without knowing.
Why does this exist:
I was throwing some items in the trash and accidentally clicked in my golden backpack with 1 hour worth of ores.
Known issues:
Due to this being a client-side mod, all server-side operations will completely ignore your locked slots. The following list of things will not work and will not be fixed.
- If you have wood in a locked slot and uses the recipe book (or REI) to place items in the crafting table, the wood will be moved.
- If you have a locked slot with available space and walk over a dropped stack, the locked slot will be filled with the gathered item.
- If you're quick moving items from a chest to your inventory, and the locked slot has available space, it will be filled.
- If another mod tries to interact with your inventory, it'll probably work
It's likely that this mod is going to have a lot of incompatibility with other mods. Feel free to report it as an issue in the mod's GitHub page.
