About this Mod

Adds a new enchantment for the crossbow that makes you fly through the air when you fire a rocket of any level. This is not a pyrotechnic rocket, just a firework. If you shoot forward, it will work normally.

Frequently Asked Questions

RocketLauncher server crashes on startup – what to do?

Most common cause: wrong datapack 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 (1.21.11). You can switch loaders with one click in the panel.

Is RocketLauncher compatible with datapack and fabric and forge and neoforge and quilt?

RocketLauncher officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with RocketLauncher – how to optimize performance?

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