Real-time 2D rendering utilities based on SharpDX/Direct2D.

Packages

Package	runtimes	NuGet Package
FlysEngine	net6
FlysEngine.Desktop	net6
FlysEngine.Sprites	net6

Simple example

(Refer to /tree/master/FlysTest)

• Final result:
• Create a Windows-form application
• Delete the entire Form1 class
• Install the FlysEngine nuget package
• Install the SharpDX.Desktop nuget package for convenient
• In Program.cs file, using following namespaces:

  using FlysEngine;
  using FlysEngine.Desktop;
  using FlysEngine.Managers;
  using Vortice.Direct2D1;
  using Vortice.DirectWrite;
  using Vortice.Mathematics;
  using FlowDirection = Vortice.DirectWrite.FlowDirection;
  using FontStyle = Vortice.DirectWrite.FontStyle;

• Replace Main method's content to following code:

  using (var res = new XResource())
  using (var form = new Form() { Text = "Hello World" })
  {
    var timer = new RenderTimer();
    IDWriteTextFormat bottomRightFont = res.DWriteFactory.CreateTextFormat("Consolas", 16.0f);
    bottomRightFont.FlowDirection = Vortice.DirectWrite.FlowDirection.BottomToTop;
    bottomRightFont.TextAlignment = TextAlignment.Trailing;
  
    IDWriteTextFormat bottomLeftFont = res.DWriteFactory.CreateTextFormat("Consolas", FontWeight.Normal, Vortice.DirectWrite.FontStyle.Italic, FontStretch.Normal, 24.0f);
    bottomLeftFont.FlowDirection = Vortice.DirectWrite.FlowDirection.BottomToTop;
    bottomLeftFont.TextAlignment = TextAlignment.Leading;
  
    form.Resize += (o, e) =>
    {
      if (form.WindowState != FormWindowState.Minimized && res.DeviceAvailable)
      {
        res.Resize();
      }
    };
  
    RenderLoop.Run(form, () => Render());
  
    void Render()
    {
      if (!res.DeviceAvailable) res.InitializeDevice(form.Handle);
  
      var target = res.RenderTarget;
  
      timer.BeginFrame();
      target.BeginDraw();
      Draw(target);
      target.EndDraw();
      res.SwapChain.Present(1, 0);
      timer.EndFrame();
    }
  
    void Draw(ID2D1DeviceContext target)
    {
      target.Clear(Colors.CornflowerBlue);
      Rect rectangle = new Rect(0, 0, target.Size.Width, target.Size.Height);
  
      target.DrawRectangle(
        new Rect(10, 10, target.Size.Width - 20, target.Size.Height - 20),
        res.GetColor(Colors.Blue));
  
      target.DrawText("😀😁😂🤣😃😄😅😆😉😊😋😎",
        res.TextFormats[36], rectangle, res.GetColor(Colors.Blue),
        DrawTextOptions.EnableColorFont);
  
      target.DrawText("FPS: " + timer.FramesPerSecond.ToString("F1"),
        bottomRightFont, rectangle, res.GetColor(Colors.Red));
  
      target.DrawText("Hello World",
        bottomLeftFont, rectangle, res.GetColor(Colors.Purple));
    }
  }

• Compile and run.
