Extracted from beta versions of Celestial Exploration, now into its own library!

assign a space or empty dimension to be a "galaxy"
create structures to represent "planets", and set up teleportation to/from planets and the galaxy
set up various gravity effects on planets, and implement spacesuits/armor that can negate those effects when worn
add additional planets through datapacks
light speed travel system for traveling between galaxies, especially for use in modpacks with multiple space mods (for whenever it is I write those other mods…)

Frequently Asked Questions

Celestial Lib 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 (1.18.2). You can switch loaders with one click in the panel.

Is Celestial Lib compatible with forge?

Celestial Lib officially supports forge for Minecraft 1.18.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Celestial Lib – how to optimize performance?

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