Autotiler

Unpacks tilesets from a compressed one

Pure go. No external dependencies

Disclaimer

Project is in alpha state. Was quickly developed to do stuff, so code is not pretty, but functional.

Features

Autotiler unpacks tileset like this to formats more suitable for map generation (e.g. 16 and 47 wang tilesets):

How to use

• get yourself Go

• clone this repository or download sources.

• put simple tileset image (for example 2x3_packed.png) to source folder

• run go run . -in <file_in> [-o <file_out>] [-p <padding>] [-e <export_type(16,28,48,all)>]

  e.g. go run . -in ./examples/2x3_packed.png -o ./out/output.local.png -p 1 -e 16 -e 28 -e 48

• you can optionally set padding for tiles in px. To do so you need to add desired padding as argument:

  e.g. go run . -in ./examples/2x3_packed.png -p 1 - this will create tilesets with 1 px margin and 2px spacing.

• grab complete tilesets from directory specified in -o.

• you can pass several -in and -o parameters to unpack several tilesets at once. They will match the order. In case there are fewer -o parameters, the default name will be used and results will be placed in current directory.

• alternatively you can just run make unpack FILE_IN=<file> and it will place all results in ./out directory

• don't worry about filenames, as program will automatically prefix output files with necessary information. E.g. for options -o ./out/output.local.png -e 16 output files will be ./out/16x1_terrain1_output.local.png and ./out/16x1_terrain2_output.local.png

• enjoy

• alternatively you can build an application using make build command to use it as a standalone application without Go

Output Examples

16x1 Terrain 1 to 2:

14x2:

14x2 (with 1px padding):

12x4 Terrain 2 to 1:

Roadmap and plans

• Unpack from 6 tiles to 16 tiles
• Unpack from 6 tiles to 28 tiles
• Unpack from 6 to 47 tiles
• Unpack from 6 or 16 tiles to 256 tiles
• Export to Tiled
• Export to Godot
• More build options (Win, Mac)
• Document, prettify code and make application more versatile
