RhythmBase

[ English | 中文 ]

A high-performance, systematic, and intuitive level editing proxy development library for rhythm game developers, independent of any game engine.

Development progress is tracked here.

Examples can be found here.

Architecture Overview

RhythmBase                         ← Core library (NuGet package)
├── Global/                        ← Public interfaces, types, serialization infrastructure
│   ├── Components/                ← Color, EnumCollection, TickTime interface, Level interface...
│   ├── Events/                    ← IEvent, IDurationEvent, IFileEvent, IForwardEvent...
│   ├── Converters/                ← MetadataJsonConverter, MemberConverter, TypeConverterRegistry...
│   └── Extensions/                ← LINQ queries, event navigation...

RhythmBase.Generator              ← Source generator (Roslyn Incremental SourceGenerator)
└── Auto-generates: EventTypeRegistry / EventConverterMap / EnumConverterExtensions

RhythmBase.RhythmDoctor            ← Rhythm Doctor adapter
RhythmBase.Adofai                  ← A Dance of Fire and Ice adapter
RhythmBase.BeatBlock               ← BeatBlock adapter
RhythmBase.Rizline                 ← Rizline adapter

Serialization system: The core library provides MetadataJsonConverter<T> (handles compound objects like Level, Settings, Row, etc.) and MemberConverter<T> (reads/writes event properties field by field). The source generator automatically produces converters and type-enum mappings for each event class based on declarations in AssemblyInfo.cs, eliminating the need to write serialization code by hand. See Tutorial Part 2 for details.

Supported level formats:

Key Features

• Complete event system support
  Provides strongly-typed event models for rhythm games, compatible with future new event models.
• Smart event handling
  Flexible LINQ queries, automatic relationship management, and built-in timeline generation tools.
• RichText and dialogue components
  Full rich text syntax parsing and code generation for dialogue and title events.
• Source generator driven serialization
  AOT-compatible JSON serialization with no reflection; converters for event types are automatically generated by the Roslyn source generator.
• Bitmap enum collections
  High-performance EnumCollection<T> / ReadOnlyEnumCollection<T> for event type classification and filtering.
• Cross-platform
  Based on .NET Standard 2.0 / .NET 8.0, supporting Windows, Linux, macOS.
• AOT compatible
  No reflection calls, fully supports AOT compilation.

Quick Start

dotnet add package RhythmBase.RhythmDoctor

using RhythmBase.RhythmDoctor.Components;
using RhythmBase.RhythmDoctor.Events;

// Load level
using var level = Level.FromFile("level.rdlevel");

// Add event
level.Add(new Comment() { Text = "hello", Tab = Tab.Windows, Y = 2 });

// Save
level.SaveToFile("out.rdlevel");

About This Project

This project was originally named RhythmToolkit, aiming to develop small tools to simplify level processing for Rhythm Doctor.
As the project matured, its direction shifted toward becoming a foundational framework for other tools, and it expanded to support the A Dance of Fire and Ice (Adofai) level model.
For this reason, the project was renamed RhythmBase, and tool-oriented content was migrated to other repositories. Of course, you can also call it RDTK!
