Updates to main()

In the spirit of yesterday’s refactoring efforts…

main() serves as a great example of yesterday’s restructuring in practice: The OpenGLDevice is created, then passed to a GLFWApplication which manages window creation and the main loop. The ultimate goal is for the application to own and provide the input system, further simplifying the program’s entry point and properly encapsulating platform-specific details within the appropriate module.

int main() {
    // 1. create the rendering device
    const auto opengl = std::make_unique<heliosOpenGl::OpenGLDevice>();
    // 2. create the config for the main window
    auto cfg = heliosGLFWUtil::GLFWFactory::makeWindowCfg("helios - Simple Cube Renderer");

    // 3. create the app.
    const auto app = heliosGLFWUtil::GLFWFactory::makeApplication(opengl.get());

    // 4. create the main window
    heliosWinGlfw::GLFWWindow& win = app->createWindow(cfg);

    // 5. initialize the app
    app->init();
    // ... and set focus to the window
    app->focus(win);

    // get the InputManager
    auto& inputManager = app->inputManager();

    while (!win.shouldClose()) {
        inputManager.tick(0.0f);

        if (inputManager.isKeyPressed(heliosInput::Key::ESC)) {
            std::cout << "Key Pressed [ESC]" << std::endl;
        }

        win.swapBuffers();
    }

    return EXIT_SUCCESS;
}

Tickable

A small milestone has been reached - the first tick() is now alive in the main loop, marking the first rhythmic pulse in helios’s engine (heh!). The clock (i.e. float deltaTime) has officially started.
