Transitions is an object-oriented finite state machine library for Python. It provides a framework for managing valid states and the logic for moving between them, including implementations for asynchronous state machines and thread-safe state managers. The library supports hierarchical state machines that allow states to be nested to organize complex subtasks and logical contexts. It includes tools for generating visual diagrams of states and transitions to document machine logic. The project covers state management primitives such as lifecycle callbacks, conditional transition guarding, an

Entitas-CSharp is a data-oriented architectural framework for managing application state and logic in C# and Unity environments. It implements the Entity Component System pattern to separate raw data components from the logic systems that process them. The framework includes a code generator that automatically produces type-safe boilerplate classes and methods at build time. It also provides a visual state inspector for examining entities and components in real time within the Unity editor. The library covers data-oriented programming and game state debugging, utilizing a memory-efficient ap

This library is a finite state machine framework for JavaScript designed to manage application states and valid transitions. It provides a system for executing state changes with lifecycle hooks, conditional guards, and transition cancellation. The project is distinguished by its ability to inject state machine logic and transition capabilities directly into existing JavaScript class instances or objects. It also includes a visualization tool that exports state configurations into Graphviz DOT language for auditing system logic. The framework covers asynchronous transition execution and paus

EnTT is a C++ library designed for data-oriented design and entity component system architecture. It provides a framework for managing game objects and simulation states by separating entity data from logic, allowing for the efficient organization and manipulation of large collections of related data objects. The library utilizes sparse sets to store entities and components in contiguous memory, which facilitates cache-friendly iteration and constant-time lookups. It employs template metaprogramming for compile-time type reflection and type-erasure techniques to provide a unified interface fo

Flecs is a high-performance entity component system framework and data-oriented programming library. It serves as a simulation engine core and game engine architecture tool, decoupling state from behavior by separating entities, components, and systems. The framework features a runtime reflection layer for dynamic data inspection and a built-in scripting system for defining entity behavior without recompilation. It also includes a network interface and REST API for remote simulation administration and state querying. The library covers a broad surface of simulation capabilities, including ar

Fluid Behavior Tree is a code-driven framework for Unity designed to manage autonomous character behaviors through hierarchical decision-making structures. It functions as a game AI logic engine that processes complex entity behaviors by traversing directed graphs of nodes that return success, failure, or running status signals during each frame update. The library distinguishes itself through a fluent builder pattern that allows developers to define nested tree structures, sequences, and parallel execution flows entirely through chainable code methods. This approach emphasizes modularity, en

This project is a Ruby library for defining and managing object lifecycles through states, events, and transition rules. It functions as a declarative workflow engine that enforces business logic by restricting attribute changes to predefined, valid paths within Ruby classes. The library distinguishes itself through deep integration with database persistence layers, allowing it to automatically synchronize state changes with data models, validation frameworks, and transaction management. It supports dynamic configuration, enabling the construction of lifecycle rules at runtime from external d
