GalMC API

by zengikun

GalMC API is a Forge library for building Galgame-style visual novel scenes inside Minecraft, with a dialogue interface that runs in-game.

ForgeClient and serverMIT LicenseOpen source1.20.1

What it does

Inside Minecraft, the mod supplies an engine that draws visual novel dialogue and scenes. Its main purpose is to give developers a simpler way to build GalGame-style adventures. It ships no storyline content of its own and works as a functional framework that other projects can build on.

Custom scenes are set up by placing a resource pack in a specified directory and then starting play with in-game commands. Developers can insert visuals and novel-style text at key moments in place of traditional signboards, which suits adventure maps and modpacks. The author states that event-driven automatic triggers and a custom progress system are planned for later versions.

GalMC API runs on Forge for Minecraft 1.20.1 only. Client and server both need it, so every player and the server must install it. The code is open source under the MIT License, with public source code and an issue tracker.

  3. Command-driven playback

  4. Developer framework
