GitHub - neogeek/rhythm-game-utilities: A collection of utilities for creating rhythm games in Unity, Unreal, Godot and SDL.

Caution

This package is in early development and should not be used in production.

This library is a collection of utilities for creating rhythm games like Tap Tap Revenge, Guitar Hero, and Rock Band. It is meant to be used within any game engine that supports loading C++ libraries, such as Unity, Unreal, Godot and SDL.

Prototype game built using these utilities.

Features

🎵 Parse .chart and .midi song files
🎼 Calculate position to render notes
💯 Calculate hit accuracy
🥁 Determine if the current time is on the beat
💫 And more!

Platforms

This library aims to offer support for multiple platforms through a single codebase. This is highly ambitious, so if you run into an issue with your platform of choice during development, please leave a detailed bug report with as much information as possible. Also, as this library is relatively new, mobile platforms will be fully supported after all other platforms are complete.

Unity Plugin

The Unity plugin includes compiled C++ libraries (macOS, Windows and Linux) and wraps the internal calls in native C# functions. These functions pass and retrieve the data from the C++ library and clean up memory upon completion.

Unreal Plugin

There isn't a custom wrapper or plugin for Unreal, as the C++ library works as is when included as a header-only library.

Godot Plugin

Coming soon.

SDL Library

There isn't a custom wrapper or plugin for SDL, as the C++ library works as is when included as a header-only library.

Git Hooks

The git hooks that run are quick file checks to ensure the files in the dotnet project and the UnityProject are the same and that the build files haven't changed.

$ git config --local core.hooksPath .githooks/

Testing

Run all tests via make test.

Tests for the C++ library are authored using the C++ native library cassert.
Tests are run automatically via GitHub Actions on each new PR.
For you add a new feature or fix a bug, please include the benchmark output in the PR along with your device stats.

If you want to test the project from within Unity, add the test namespace to your project by adding the following to your Packages/manifest.json file:

{
...
    "testables": ["com.scottdoxey.rhythm-game-utilities"]
...
}

Build

Warning

Do not commit any build changes to the repo. The build files are automatically generated via GitHub Actions.

macOS

When developing on macOS, make sure that Mac is selected in the bottom right-hand corner of Visual Studio Code or C++ Intellisense will not work.

./bin/build.sh

Windows

When developing on Windows, make sure that Win32 is selected in the bottom right-hand corner of Visual Studio Code or C++ Intellisense will not work.

Run from x64 Native Tools Command Prompt for VS:

call "./bin/build.bat"

Contributing

Be sure to review the Contributing Guidelines before logging an issue or making a pull request.

Community Roadmap

This project aims to help you build your rhythm game as fast as possible without needing to learn the complexities of a new library. Instead, you can utilize comprehensive examples and simple code recipes If you have feature requests or bugs, please create an issue and tag them with the appropriate tag. If an issue already exists, vote for it with 👍.
