The underlying system includes capabilities for static site compi

QFramework is a Unity game architecture framework designed to separate presentation, system, and data logic. It implements a layered software architecture to manage complex game states and provides a game engine utility library to reduce boilerplate code. The framework is centered on the Command Query Responsibility Segregation pattern, which separates data modification commands from data retrieval queries. It utilizes a dependency injection container to manage the lifecycles and resolution of singletons and modular components, alongside an event-driven system for state synchronization to pre

This project is a reference collection of practical examples demonstrating the implementation of common software design patterns in Kotlin. It serves as a guide to architectural best practices and object-oriented principles through the application of behavioral, creational, and structural patterns. The collection provides concrete implementations to demonstrate how to decouple object instantiation, manage communication and responsibility between objects, and organize complex class and object relationships. The reference covers creational patterns such as factories and builders, structural pa

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

Mindustry is a cross-platform game engine and factory automation simulation that combines resource management with tower defense strategy. Players construct complex supply chains and automated networks to process materials while building defensive structures to protect a core from waves of hostile mechanical forces. The project utilizes a deterministic lockstep networking model to ensure simulation consistency across desktop and mobile devices. It is built on an entity-component-system architecture and a tile-based grid simulation, allowing for the efficient management of thousands of active

Beehave is a behavior tree AI framework and plugin for the Godot engine. It serves as an agent logic orchestrator for designing adaptive non-player character behaviors using hierarchical behavior trees. The system features a visual debugger that provides runtime visualization of the execution flow and internal state of active trees. This allows for AI execution analysis and the identification of logic errors through a state-based runtime interface. The framework utilizes a composite-decorator pattern and a tick-based polling cycle to execute tree-based logic. It integrates directly with the

Entitas is a data-oriented Entity Component System framework for Unity. It is designed to separate game state into components and logic into systems, utilizing a data-oriented design to optimize CPU cache usage, memory usage, and processing speed. The framework includes a C# source code generator that automatically produces boilerplate classes, entity accessors, and context singletons to reduce manual coding. It also provides a Unity editor debugging tool for real-time runtime state visualization, system performance monitoring, and visual entity inspection. The system manages entity lifecycl
