Purpose: YATME is a browser-based OpenTibia map editor for Tibia 15.00+ client data.
Map files: It renders and edits OTBM map files using sprite data extracted from the Tibia client.
Inspiration: The project says it was inspired by Remere's Map Editor.
Self-hosting: The README describes hosting the editor alongside an OTS server for map development and administration.
Deployment: The README provides Docker Compose and Docker run instructions, with the editor available at localhost port 8080 by default.
Required assets: The editor requires asset files from a Tibia 15.00+ client, an .otbm map file, and optionally related sidecar XML files.
Sprite handling: On first startup, sprite sheets are automatically converted from .bmp.lzma to PNG, and the converted sprite cache persists across container restarts.
Asset storage: The Docker setup mounts Tibia client assets read-only and map files read-write so the editor can save changes.
Technology: The project is built with React 19, PixiJS 8, TypeScript, and Vite.
License: The repository identifies the project as MIT licensed.
Local development: The README lists Node.js 22 or later as a prerequisite for local development.
Maker information: The repository is publicly hosted under the GitHub account knobik; the opened maker pages do not state a company name, headquarters, or founding date.
