Description
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 generateMasses` and 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)
