A C++11 header-only ECS (entity-component-system) library (no longer updated but feel free to use or extend it)

Overview

The latest branch of this engine presents a complete rewrite of the original 1.0 version, moving away from its prior design influenced by C++03. This header-only library allows for easy integration into projects by simply adding the include directory, making it convenient for developers to start utilizing its capabilities right away. With various sample projects to guide you, getting accustomed to the features and functionalities is a breeze, especially with samples like the 'balls' demo serving as a perfect introduction for beginners.

Designed to manage entities and their components efficiently, this engine provides a robust framework that's flexible and straightforward. The core of the library revolves around the World class, which serves as the central hub for managing all game systems and entities. With support for real-time updates and component management, this engine allows for the dynamic creation and modification of game elements, enhancing the overall gaming experience.

Features

  • Header-only Library: Easy to integrate into any project by simply including the necessary headers, eliminating complex installation procedures.

  • Entity Component System (ECS): Allows for the creation of entities that are modular and flexible, enabling runtime modifications and customizations via data classes known as components.

  • Dynamic Component Management: Components can be added or removed from entities on the fly, promoting a dynamic gaming environment where entities can evolve during gameplay.

  • Efficient Iteration: Internally uses a flat array to maintain up-to-date mappings of entities and components for swift iteration, minimizing performance overhead.

  • World Class Coordination: The World class orchestrates all game systems and provides default behaviors, simplifying the management of game logic and components.

  • Event Callbacks for Systems: Systems can define callbacks (e.g., onEntityAdded, onUpdate) which facilitate event-driven programming, enabling responsive and organized game logic execution.

  • Cross-Platform Support: Dependencies are included for Windows, with the requirement for SDL2 and OpenGL on other platforms, allowing for broad compatibility.

  • Optional Components: Components can be checked within entities and default values provided if they are absent, enhancing error handling and robustness in design.
