A love letter for Rhythm games
HyperTwist is a Rhythm engine, editor and game.
Nowadays there are several 4-pad foot rythm games. However, I personally feel that none of them delve inough into their mechanics, leaving them for more ideas that can be exploited. This game aims to expand on these innovative features and improved gameplay that promise to engage players and enhance their experience.
- Song Processing (.sm, .ssc)
- Song resources and properties loader
- Chart loader (notes, difficulty...)
- Song Conversion to (.smd, .scd)
- .smd (Step Main Data) Saves the main info about a Song, to avoid a load overhead with charts.
- .scd (Step Chart Data) Saves the chart data in a more compressed way than .sm and .ssc files, reducing memory space.
- Game Loop
- Basic game pipeline added:
- Dev Window:
- View and edit game config.
- Main Menu:
- Account Screen:
- Mode Select:
- Song Select:

HyperTwist works thanks to the following libraries:
| Plugin | Purpose | README |
|---|---|---|
| SDL2 | Window creation & management | SDL2/README.txt |
| GLEW | Graphics programming with OpenGL | glew/README.md |
| SFML | Multimedia API | SFML/README.md |
| FreeType | Font rendering | freetype/README |
| ImGui | GUI library for C++ | imgui/docs/README.md |
| OpenAL (Old) | Audio programming | openal.org |
Previously, the project worked just with a Visual Studio Solution (.sln). However, with the new updates to the project, now it works a CMake project.
To configure CMake, select a build configuration, and after a successful CMake generation, compile the C++ code to execute the program.
Note: User might have to install some dependencies from the libraries mentioned above.
Want to contribute? Great! Everyone is welcome to request, create a discussion/pull request, and improve the project!
The project is build using CMake, with each configuration structured as the following:
[PLATFORM] Project - Build_Config
For the future the project might support Mac, FreeBSD or other configurations.
