Changes in release 0.61.1

• Game base class now implements IDisposable.

Changes in release 0.61.0

• Added Vector2 and Vector3 constructors for Camera class.
• Added a convenient way to cut a sub-texture out of a larger texture.
• Removed obsolete overloads for RenderTo, WithCamera and Batch RenderContext calls.

Changes in release 0.60.1

• Added extension methods overloading Rumble and RumbleTriggers for ControllerDriver allowing use of float values in range 0.0-1.0.
• Updated SDL_gpu to draw pixel-perfect lines and rectangles, thanks to Avahe Kellenberger.

Usage

Simply reference this package and use the following template to get started:
GameCore.cs

using System.Numerics;
using Chroma;
using Chroma.Graphics;

namespace MyGame
{
  public class GameCore : Game
  {
    public GameCore()
      : base(new(false, false))
    {
    }

    protected override void Draw(RenderContext context)
      => context.DrawString("Hello, world!", new Vector2(16, 16));
  }
}

Program.cs

using System;

namespace MyGame
{
  static class Program
  {
    static void Main(string[] args)
      => new GameCore.Run();
  }
}

Examples of how to use Chroma's can be found in the example repository.
