Some Sample dxE Code (3/30/2017)

Hey everyone!

I thought I'd show a quick sample of dxE (my game-independent library) code. dxE has recently been almost completely rewritten in C, as I've abandoned my object-oriented approach. The only C++ code I have yet to replace is my use of GLM, which I'll be replacing soon with the HandmadeMath library.

The new rewrite of dxE currently supports:

-Multiple Windows
-Keyboard/Mouse Input
-Resources (Shaders, Textures, Fonts, Audio)
-Multi-threaded Resource Management (Parses requests, loads in resources as needed, allows for dynamic loading screens and loading during gameplay)
-Output (Audio, Rendering)
-Custom shader support; can use raw OpenGL alongside dxE if needed, but drawing primitives/textures/text doesn't require any custom shaders (default shaders provided)

I'm really just implementing features as I need them for my game, but I have quite a bit more planned.

Here's that sample:

            dxE_update_window(window);

            dxE_finish_render(window);
        }
    }

    dxE_free_timer(timer);
    dxE_free_window(window);

    dxE_clean_up();

    return 0;
}


Hope this was interesting; let me know if you want to see more or if you'd like to see some under-the-hood details.
