EngineKit

Abstraction over modern OpenGL.

It tries to hide the ugliness of the global state machine that is OpenGL.

Getting Started

It is a little cumbersome, but bare with me.

Create two projects

• YourProject as a console project
• YourProject.Assets as a class library project (your IDE might have created a Class1.cs file, you can delete that safely)

---

• Add YourProject.Assets as a project reference to YourProject.
• Copy Fonts directory from here into YourProject.Assets (i am working on a neater solution)
• Add EngineKit to YourProject via nuget as a usual package.
• We also need a few other packages:
  • Microsoft.Extensions.Configuration - handle configuration in general
  • Microsoft.Extensions.Configuration.Json - to load appsettings.json
  • Microsoft.Extensions.Options.ConfigurationExtensions - to turn sections of the configuration into usable objects
  • Microsoft.Extensions.DependencyInjection - that's the dependency injection container we use here
  • Serilog.Sinks.Console - to print log statement to the console
  • Serilog.Settings.Configuration - an adapter for serilog to get its configuration from our configuration object
• Create an appsettings.json in YourProject which should like like this one.
• Make sure to have it copied when its newer by right clicking it -> Properties -> "Copy to output directory" -> "Copy if newer"

---

• Create a class YourProjectApplication in YourProject and let it derive from GraphicsApplication (let your IDE implement the constructor, if you cannot figure it out look at this constructor for inspiration)
• Program.cs of YourProject should look like

using EngineKit;
using EngineKit.Extensions;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Serilog;

namespace YourProject;

internal static class Program
{
    public static void Main(string[] args)
    {
        using var serviceProvider = CreateServiceProvider();

        var application = serviceProvider.GetRequiredService<IApplication>();
        application.Run();
    }

    private static ServiceProvider CreateServiceProvider()
    {
        var configuration = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json", false)
            .Build();

        Log.Logger = new LoggerConfiguration()
            .ReadFrom.Configuration(configuration)
            .CreateLogger();

        var services = new ServiceCollection();
        services.AddSingleton(configuration);
        services.AddSingleton(Log.Logger);
        services.Configure<WindowSettings>(configuration.GetSection(nameof(WindowSettings)));
        services.Configure<ContextSettings>(configuration.GetSection(nameof(ContextSettings)));
        services.AddEngine();
        services.AddSingleton<IApplication, XXX>(); // replace XXX with YourProjectApplication 
        return services.BuildServiceProvider();
    }
}

• Run it.
• You should get a black window which you cannot close :)
• For that you can implement YourProjectApplication's Update method via

protected override void Update(float deltaTime)
{
    base.Update(deltaTime);
    if (IsKeyPressed(Glfw.Key.KeyEscape))
    {
        Close();
    }
}
