Two scripting layers
Use VNS for dialogue and branching. Use JES for entities, timelines, input, physics, and custom scenes.
A programmable visual novel engine for Java.
Java Vector Nexus combines narrative scripting, real-time 2D scenes, animation tooling, and a modular runtime. Build conventional visual novels or extend the engine with Java when a project needs more.
Current release · v0.8.0
What’s new in v0.8.0
More reliable project editing, asset loading, saves, and live reload. Workspace indexing handles folder-link cycles, file creation preserves existing work, and rename actions reject directory paths.
Asset packs now use direct ZIP lookup and streaming reads. Image-cache accounting, concurrent save writes, audio settings, and plugin compatibility checks are more robust.
Hot reload listens only on localhost, bounds client work, and closes connections on shutdown. Existing project and save formats remain unchanged. JVN continues to ship from source with JDK 21.
