DEngine

Overview

dEngine is a simple 2D game engine written in C++. This project was primarily a hobby effort to learn C++ and game development concepts.

The engine uses the SDL library for graphics, audio, and windowing. Its architecture is state-based, allowing different game states (like a title screen or a game level) to be pushed onto and popped from a main game loop. The core dengine provides systems for:

• Game Objects and Components: A base GameObject class that functionality is added to via Component classes, such as SpriteSheet for animations.
• UI System: A UI manager that renders UIWindow objects, which in turn are collections of UIComponent elements like Text and ProgressBarH.
• Event Management: An EventSystem that allows game objects to register callbacks for user input, such as mouse motion and button clicks.
• Audio: An AudioManager for loading and playing sounds.
• Logging: A third-party library, NanoLog, is integrated for logging engine events.

In addition to the engine itself, the project also includes:

• packer-util: A command-line utility for packing game assets (like images and audio) into a single compressed .dat file using zlib.
• examples/Game: A simple game demonstrating the engine’s features, including a title screen and a basic level with a player and enemies.
• Documentation: The project is configured to use Doxygen to generate documentation, with a GitHub Actions workflow to automatically build and deploy the docs to GitHub Pages.

Technologies Used

• Core Language: C++17
• Libraries:
  • SDL2: Used for windowing, graphics, and audio.
  • SDL2_image: Used for loading image formats (e.g., .png).
  • SDL2_ttf: Used for rendering TrueType Fonts.
  • zlib: Used by the packer utility for asset compression.
• Build & Dependencies: CMake is used as the build system, and vcpkg is used for managing dependencies.
• Logging: NanoLog
• Documentation & CI/CD: Doxygen and GitHub Actions
