AutoTiles Helper


You must be logged in to obtain assets


AutoTiles Helper is a set of scripts providing functionalities to expand compressed tilesets into a set of 47 tiles, and get their respective index when placed into a room based on adjacent tiles. You just have to provide the tileset, and the scritps will automatically figure out which tile is appropriate for a particular spot.


  • Automatically get the correct tile images based on the adjacent tiles
  • Generate a complete tileset from a compressed one. No need to draw every single tile!
  • Fully documented and commented

If you are just interested in the tile expander functionality, download the sample project:
