YATME — Browser-Based Map Editor for Tibia 15.00+ (Open Source)

[Knobik]

Hey everyone!I've been working on YATME (Yet Another Tibia Map Editor) — a fully browser-based map editor for OpenTibia servers running Tibia 15.00+ client data (protobuf format). It's open source under MIT license.

Why another editor?
RME is great but it's a native C++ app that can be tricky to build and maintain. YATME runs entirely in the browser — no installs, no dependencies. Just load your map and start editing.

What's implemented:

• Full OTBM load/save with Tibia 15.00+ protobuf data pipeline
• GPU-accelerated rendering via PixiJS 8 with multi-floor support (RME-style diagonal offset)
• 9 tools: Select, Draw, Erase, Fill, Door, Zone, House, Creature, Waypoint
• Brush system: Ground brushes with auto-borders, wall brushes with corner detection, carpet/table brushes, doodad brushes, raw item placement
• Variable brush size (1-13 tiles) and shape (square/circle)
• Undo/Redo, Cut/Copy/Paste, drag-move
• Find Item, Replace Items across map
• Borderize and Randomize selection
• Zone painting (PZ, No PvP, No Logout, PvP, Refresh)
• House region editing
• Monster/NPC spawns with configurable spawn times
• Town/temple management
• Import/Export for zones, houses, monster/npc spawns (XML sidecar files)
• Minimap, light rendering, animations
• Tile Inspector with full item property editing
• Go to Position, keyboard shortcuts for everything

Tech stack: React 19, PixiJS 8, TypeScript, Vite, Tailwind CSS 4

GitHub: GitHub - knobik/yatme: Yet another Tibia map editor (https://github.com/knobik/yatme)

Still a work in progress but already quite usable, 90% of features implemented. Would love feedback, bug reports, or contributions!

This looks really promising.
Browser based map editor is a big win by itself.
How is performance on really big maps? Especially undo/redo, multi-floor rendering and saving sidecar xml files.

Hi,

Nice contribution!

If it's entirely on browser stack, then maybe it can be put on github.io? So everyone can access without building. Possible? Just a doubt.

Hey there! I love the idea of YATME as a browser-based map editor for Tibia. The open-source aspect makes it even cooler! I'm curious, what features do you think are the most essential for new users getting started? Also, have you encountered any common challenges while using it?

So, what do you think about a fully browser-based map editor like YATME for OpenTibia? Do you see it as a significant improvement over native tools like RME, especially regarding ease of access and maintenance?
