Tools for osu!.

• A desktop platform with the .NET SDK 5.0 or higher installed.
• When working with the codebase, we recommend using an IDE with intellisense and syntax highlighting, such as Visual Studio 2017+, Jetbrains Rider or Visual Studio Code.
• These instructions assume you have the the CLI git client installed, but any other GUI client such as GitKraken will suffice.
• Note that there are additional requirements for Windows 7 and Windows 8.1 which you may need to manually install if your operating system is not up-to-date.

• Clone the repository including submodules (git clone --recurse-submodules https://github.com/ppy/osu-tools)
• Navigate to each tool's directory and follow the instructions listed in the tool's README.
  • PerformanceCalculator - A tool for calculating the difficulty of beatmaps and the performance of replays.

Most relevant code is in the main ppy/osu repository. To make any meaningful changes you will likely need to edit that as well.

• Clone all relevant repos into the same directory (git clone https://github.com/ppy/osu-tools; git clone https://github.com/ppy/osu)
• Run the ./UseLocalOsu.ps1 powershell script (or ./UseLocalOsu.sh) to use your local copy of ppy/osu
