StarRailExpress Library Mod

by StaredTrain

StarRailExpress Library Mod is a Fabric library that supplies the shared code, commands and sound resources for the StarRailExpress game mod and its add-ons.

FabricClient and serverBUSL-1.1 AND CC-BY-NC-4.01.21.1

What it does

Developers who build a plugin for StarRailExpress use this library as the base layer. It collects general utilities taken from the StarRailExpress project, along with development libraries and resources the main game depends on. Its sound package provides the effects that accompany the game's items and roles, so the game can play its audio.

The library also registers its own command set under sre:lib and a math command that evaluates expressions such as sin and cos, returning a numeric result. Players do not need to run these to enjoy the game; they exist so the game and its tooling can call them. Installation places the mod in the mods folder next to StarRailExpress, and StarRailExpress - Wathe Addon requires it.

Key features

  1. Shared utility code

    General helper code from the StarRailExpress project is packaged here so other builds can reuse it.

  2. Sound package

    Sound effects for the game's items and roles are bundled, covering characters such as the Jester, the Singer and the Gambler.

  3. Command set

    Commands registered under the sre:lib namespace are available for scripting and for the game's own use.

  4. Math command

    A math command evaluates expressions with functions such as sin and cos, returning a decimal result.
