About this Mod
Updraft
Updraft is a server-side datapack that works on Vanilla, Fabric, Quilt, Forge, and NeoForge loaders.
This datapack attempts to add an early-mid game (before elytra) method of flight/vertical transportation that encourages player infrastructure.
Features
Updraft adds the titular updraft, a column of air sourced from an end crystal that has been transformed by using a Gust Core nearby. Also added is the Parachute Vest, a chestplate utility piece that applies slow falling when jumping from high heights (~5 blocks up). Given that using an Updraft may be perilous (fall damage!), the Parachute Vest is designed to be used with the Updraft to not only prevent death by fall damage, but also to allow for air travel.
The Gallery provides the crafting recipes for the Gust Core and Parachute Vest.
To give yourself the items with commands, run/loot give @s loot updraft:items/gust_core for the Gust Core, and/loot give @s loot updraft:items/parachute_vest for the Parachute Vest.

To install this datapack, download the version for your game version, place it in your world's datapack folder and in your resourcepack folder, then enable the resourcepack.

Updraft 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.

Updraft officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11, 1.21.10, 1.21.9. 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 Updraft – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Updraft consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
