Autotiler CLI
If you're making a 2D game with tilemaps, you've probably dealt with autotiles. You draw a few edge and corner tiles, and the engine figures out which tile to use based on neighboring cells.
The annoying part: most engines expect a specific 47-tile "blob" tileset format, but it's way easier to draw a minimal 15-tile Wang tileset. Converting between them manually is tedious.
Autotiler CLI does the conversion automatically.
npm install -g autotiler-cli
# Generate a blob tileset from your Wang tileset
autotiler input.png -o output.png
# Or export directly as a Godot TileSet resource
autotiler input.png -g
The Godot export includes pre-configured bitmasks and collision shapes, so you can drop it straight into your project.
This is a CLI fork of itsjavi's Autotiler Electron app - same algorithm, but usable in build scripts and CI pipelines.
