About this Mod

Build Bugs is a small utility mod that focuses on speeding up the process of reporting a (build-) bug on MCC Island. This is mostly aimed to be used by the MCC Island testers, but can be used by anyone.

You need Minecraft 1.21.11 and at least Noxesium 3.0.0.
See the Modrinth page for older versions of Builds Bugs.

Usage

This mod adds the /buildbug command and two hotkeys, the first hotkey (default U) is used to quickly gather
information about your location.
The second hotkey (default I) is used to quickly generate a /bugreport.

  • /buildbug - Prints out location information, same as the hotkey.
  • /buildbug config clipboard <true/false> (default: false) - If set to true, automatically copies any /bugreport links or /buildbug coordinates to the clipboard.
  • /buildbug config debug <true/false> (default: false) - If set to true, prints out any incoming noxesium packet and information about the current internal state.
  • /buildbug config eventip <IP> (default:example.com) - Allows the mod to also function on the specified server.
  • /buildbug forcestate <type> <subtype> <map> - Forces the internal state of the mod.
  • /buildbug resetstate - Resets the internal state of the mod.
  • /buildbug version - Prints out the version of the mod.

Frequently Asked Questions

Build Bugs server crashes on startup – what to do?

Build Bugs officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Build Bugs – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Build Bugs consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
