This is the code used for the project A Mixed-Initiative Tool for Designing Level Progressions in Games, which appeared in UIST 2013. It is not intended as a usable piece of software, but rather as reference for other systems. Meaning, it's half-functional research code with both wildly out-of-date documentation and a lot of bugs. You have been forewarned. You can see a video of a functional version here.
The tool is a webapp backed by the Flask python web server, using answer set programming to do the heavy lifting on the backend.
Requirements:
- python and all the packages listed in
requirements.txt. - gringo and the disjunctive version of clasp (claspD), somewhere on the path. You can download them here, but you might have to build claspD from source: http://potassco.sourceforge.net/index.html
With those in hand, cd html/ and run python main.py to launch a web server on port 5000. Navigate to http://localhost:5000/editor/refraction to start the tool.
