CMGEngine

CMGEngine is a C++ game engine developed by David Jordan (created in 2015). Uses OpenGL for graphics. Uses CMake to build. Currently being tested on Windows 10.

Libraries

• CMGCore: Core engine functionality and framework
• CMGMath: Math types such as Vector2f and Matrix4f
• CMGGraphics: Graphics library for drawing and rendering 2D and 3D using OpenGL
• CMGApplication: High level application level code including resource management.
• CMGInput: Keyboard, mouse, and joystick input system using DirectInput8.
• CMGPhysics: 3D physics engine.

Dependencies

• FreeType: Vectorized fonts
• OpenGL & Glew: Graphics library
• SOIL: Image loading and saving
• lodepng: Image saving for PNG
• DirectInput8: user input
• WinSDK
• Catch: unit tests
• Googletest: unit tests

TODO

• General
  • Create an audio engine
  • Start using cmg namespace everywhere
  • Create CMake example project
  • Stop using struct/enum pairings, use enum class
    • decide on standard for enum names, k_enum or enum_value, and apply to code
  • Start using smart pointers where necessary, like Graphics2D
    • remove sptr where not necessary like in SetShaderUniform
  • Add event-based code
    • window
    • input: key, mouse, joystick, plug-in, unplug
      • Keyboard events/mouse events (might need to use Win32 instead of directinput)
    • physics
• Core
  • Mutex and Thread wrapper
  • Better 'Error' handling, that show proper traceback
• Graphics
  • delete Renderer class
  • Make FreeType/SOIL compiled into cmgGraphics lib
  • 3D Model importing
    • OBJ & Materials
  • ECS systems for rendering
  • fix attribute location mismatches (use constant index or varying per mesh?)
  • let shader uniforms be referenced as 'array' and 'array[0]'
  • Rework DecodedImageData interface (at least for memory management)
  • generic vs specific material class

FIXME

ECS plannig: parent/child of entities transform built-in to entity 1 component type per entity components inheriting other components? Update() in component systems?
