Valkyrien Skies

What Valkyrien Skies does Valkyrien Skies is a library mod that adds a physics engine to Minecraft. But it lets you build structures out of blocks and have them move and collide with the world, other ships, players, and entities. The mod handles buoyancy so ships can float if they are light enough. It also integrates with Create, letting contraptions built with that mod become mobile. The project is in beta and the authors say they have reached only a small fraction of their planned features. ## Who it's for This mod is for players who want to build moving ships, airships, or vehicles and see them interact with the world physically. It also serves as a foundation for other developers; add-on mods like Eureka provide the actual items and controls you use in survival or creative play. If you install Valkyrien Skies by itself, you won't get new blocks or gameplay mechanics. You need at least one compatible add-on to use it in ordinary gameplay. ## Verified capabilities - Blocks can be grouped into ships that move freely. - Ships collide with world blocks, other ships, players, and entities. - Buoyancy system lets ships float on water when they're light enough. - Create compatibility allows Create machines to function on moving ships. - Provides an API and Maven repository for other mod developers to build add-ons. ## Compatibility and requirements Valkyrien Skies supports Minecraft 1.20.1 on both Forge and Fabric loaders. It's required on both client and server. The license is GNU Lesser General Public License v3.0 only. The mod doesn't list support for other Minecraft versions or loaders such as NeoForge. Because it's a library, you must install a separate add-on mod to get playable content. The project page suggests Eureka as a starting point. ## Current state The mod is in beta. The GitHub repository shows version 2.5.0-beta.3 as the current development build, with the latest published release at 2.4.11. Recent changes include an adjustable air pocket system, increased atmospheric height limit for aircraft, and a new command for future ship flooding mechanics. Debug items and classes in the mod aren't intended for regular use.
