Wave Function Collapse 2D level generator for LDTK

Introduction

This little tool aims to generate levels using the wave function collapse algorithm. It takes its input from a level in a LDTK project file.

So just create a new LDTK project, add a tileset, a tileset layer and add a level. Give it a name and add all the tiles you wish to use for generated levels. If you want a increase the probability, that a particular tile appears, just add it multiple times to the level. The tiles in this level don't need to match together.

The tool is work in progress.

Example

This level has been generated using this tileset and this LDTK project

example-output

The commandline to generate it was:

./wfcldtk -p images/demo.ldtk -l Input_1 images/output.png -W 24 -H 12 && display images/output.png

TODO

  • add LDTK project file writing
  • add another Populate() function to be able to pre-populate the output map using an LDTK level
  • add weight to tiles in slot

Usage

This is wfcldtk, a WFC level generator for LDTK.

Usage: gfn [-vd] -p <project> -l <level> [-W <width> -H <height>] [<output image>]

Options:
-p --project <project>  Read data from LDTK file <project>
-l --level <level>      Use level <level> as example for overlap mode
-W --width <width>      Width in number of tiles (not pixel!)
-H --height <height>    Height

-d --debug    Show debugging output
-v --version  Show program version

Installation

You will need the Golang toolchain in order to build from source. GNU Make will also help but is not strictly neccessary.

If you want to compile the tool yourself, use git clone to clone the repository. Then execute go mod tidy to install all dependencies. Then just enter go build or - if you have GNU Make installed - make.

To install after building either copy the binary or execute sudo make install.
