A game framework written with osu! in mind.

• A desktop platform with the .NET Core SDK 2.2 or higher installed.
• When working with the codebase, we recommend using an IDE with intellisense and syntax highlighting, such as Visual Studio Community Edition (Windows), Visual Studio Code (with the C# plugin installed) or Jetbrains Rider (commercial).

This framework is intended to take steps beyond what you would normally expect from a game framework. This means things like basic UI elements, text rendering, advanced input handling (textboxes) and performance overlays are provided out-of-the-box. Any of the osu! code that is deemed useful to other game projects will live in this framework project.

• Anywhere we implement graphical components, they will be displayed with a generic design and will be derivable for further customisation.
• Common elements used by games (texture caching, font loading) will be automatically initialised at runtime.
• Allow for isolated development of components via a solid testing environment (VisualTests and TestCases). Check the wiki for more information on how these can be used to streamline development.

Note that while we already have certain standards in place, nothing is set in stone. If you have an issue with the way code is structured; with any libraries we are using; with any processes involved with contributing, please bring it up. I welcome all feedback so we can make contributing to this project as pain-free as possible.
