nightshade-editor-0.44.1 is not a library.
nightshade-editor
Interactive map editor for the nightshade game engine. A desktop app for building, arranging, and saving .nsmap scenes that nightshade games load at runtime.
Install
The first build downloads the editor web bundle for the matching release, so installing needs network access.
What it does
Place and arrange greybox geometry, lights, and props in a 3D viewport, tune materials and the environment, and save scenes to the engine's .nsmap format.
It also ships an optional in-process MCP endpoint so an agent can drive the editor over HTTP. The bridge is compiled in by default but stays off until you enable it from the View menu or pass --mcp.
