ArrowVortex

ArrowVortex is a simfile editor for Windows. It can be used to create or edit stepfiles for various rhythm games, such as StepMania, ITG, osu!, and other games which support DDR-style and/or PIU-style panel layouts.

This is a continuation of the original project by Bram 'Fietsemaker' van de Wetering. He has graciously allowed for the open sourcing of this code so that development can continue.

About this project

Unfortunately, the source code for the 2017-02-25 release of ArrowVortex has been lost to time. The only surviving archive of source code was a development snapshot from 2016. A small group of volunteer developers put a lot of time and effort into restoring the full functionality of the 2017 release of ArrowVortex.

Some new features were introduced as well when preparing this release, and some bugs present in the 2017 version have been fixed as well.

Support and Contributing to the project

When you have questions about ArrowVortex and its functionality, make a discussion topic!

If you would like to report bugs or suggest simple features to add, please use the issue templates to do so. Make sure an issue for your problem doesn't exist before you create a new one. When the changes you would like to add are of a larger scope (e.g. adding a new subsystem to the editor or redesigning a popup window), make a discussion instead.

Pull requests to add features and fix bugs are always welcomed. Please reach out to @uvcat7 with any questions. After a contribution, @uvcat7 will add you to the repository as a collaborator.
