About this Mod

Building a mega warehouse and need to keep track of which items you have already collected? Then this mod is for you.

How to use:

Press O to open the GUI
Add or edit (RMB) tabs, which act as an item filter, showing you the items you want to see.
Click and drag items to reorder them
Right click an item to mark it as collected

Currently only tested for SinglePlayer (it stores data in World Server). That's because I prefer having 2 clients open. I will make it dedicated server compatible sometime soon.

Frequently Asked Questions

ItemCheck server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is ItemCheck compatible with neoforge?

ItemCheck officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with ItemCheck – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ItemCheck consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
