About this Mod

Calc

This is a very small yet a very important mod. It adds custom technological progression with 5 brand new items:

Transistor
Motherboard
Screen
Solar Panel
The Calc, the main item of the mod, the goal of it.
An item with an ability so strong I won't mention it here and it is up to you to find it out. (To use it just right-click).

If you want a very easy technological challenge with a small reward at the end, this mod is perfect for you

Thanks a lot to MCreator for their easy to use app.

Frequently Asked Questions

TheCalcMod server crashes on startup – what to do?

Most common cause: wrong forge 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 (1.20.1). You can switch loaders with one click in the panel.

Is TheCalcMod compatible with forge?

TheCalcMod officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with TheCalcMod – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if TheCalcMod 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.
