VLib
A utility lib for Valkyrien Skies addons.
Quick answer
Which VLib release should I use?
VLib 1.20.1-0.1.1 targets 1.20.1 with Forge. Installation on the client is optional. Installation on the dedicated server is optional. All 2 required mods have matching files.
Where it goes
Is VLib required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does VLib 1.20.1-0.1.1 need?
1.20.1-0.1.1. Change the file and its required mods may change too.
Install Valkyrien Skies, Kotlin for Forge first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does VLib add?
VLib is a library mod for Valkyrien Skies that provides many utilities for players, modpack makers, and mod developers.
For Players / Modpack Makers
- VS Player Collision Bug Fix: Going through tight vertical spaces such as trapdoors on ships will now behave as expected when the ship is rotated.
- Automatic Modded Block Mass Calculation: run
/vlib generateMassesand VLib will calculate block mass estimates for all modded blocks. It will save the masses and bundle them into a jar file in your mods folder - Assembly Stick: Right click on a build to instantly assemble it as a ship! (NOTE: this feature is currently incompatible with C2ME)
- Per-Dimension Ship Gravity: Allows you to set the default ship gravity per dimension with a datapack
- Per-Dimension Ship Scale: Allows you to set the default ship scaling per dimension with a datapack
For Developers
- Data driven features for setting MC (or datapack) structures to generate as ships
- VLibGameUtils provides functions for assembly (with or without blacklist), and getting and saving ship structure templates.
- DimensionSettingsManager allows you to query or set default ship gravity and scale per dimension (via code or datapack)
More detailed information can be found on the the wiki.
