About this Mod

Spawns a random mob when you break a block.
Uses SQLite JDBC to save the mob to the block.

SQLite JDBC has to be installed! Modrinth says that it is incompatible with 1.21.4, but it is compatible!

Frequently Asked Questions

RandomMobBlock server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.4). You can switch loaders with one click in the panel.

Is RandomMobBlock compatible with fabric?

RandomMobBlock officially supports fabric for Minecraft 1.21.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with RandomMobBlock – how to optimize performance?

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