Using Myra in Stride Engine Tutorial

1. Create new Stride Engine project.

2. Open MyGame.csproj in the text editor and add Myra package reference:

<PackageReference Include="Myra.Stride" Version="1.5.0" />

3. Reload project(File->Reload Project) in order for new dependency to show up:

4. Create new code file MyraRenderer.cs with following contents:

using Stride.Rendering;
using Stride.Graphics;
using Stride.Engine;
using Stride.Rendering.Compositing;
using Stride.Games;
using Stride.Core;
using Stride.Core.Mathematics;
using RenderContext = Stride.Rendering.RenderContext;

using Myra;
using Myra.Graphics2D.UI;

namespace MyGame
{
    public class MyraRenderer : SceneRendererBase, IIdentifiable
    {
        private Desktop _desktop;

        // Declared public member fields and properties will show in the game studio
        protected override void InitializeCore()
        {
            base.InitializeCore();
            // Initialization of the script.
            MyraEnvironment.Game = (Game)this.Services.GetService<IGame>();

            var grid = new Grid
            {
              RowSpacing = 8,
              ColumnSpacing = 8
            };
            
            grid.ColumnsProportions.Add(new Proportion(ProportionType.Auto));
            grid.ColumnsProportions.Add(new Proportion(ProportionType.Auto));
            grid.RowsProportions.Add(new Proportion(ProportionType.Auto));
            grid.RowsProportions.Add(new Proportion(ProportionType.Auto));
            
            var helloWorld = new Label
            {
              Id = "label",
              Text = "Hello, World!"
            };
            grid.Widgets.Add(helloWorld);
            
            // ComboBox
            var combo = new ComboBox();
            Grid.SetColumn(combo, 1);
            
            combo.Items.Add(new ListItem("Red", Color.Red));
            combo.Items.Add(new ListItem("Green", Color.Green));
            combo.Items.Add(new ListItem("Blue", Color.Blue));
            grid.Widgets.Add(combo);
            
            // Button
            var button = new TextButton
            {
              Text = "Show"
            };
            Grid.SetRow(button, 1);
            
            button.Click += (s, a) =>
            {
              var messageBox = Dialog.CreateMessageBox("Message", "Some message!");
              messageBox.ShowModal(_desktop);
            };
            
            grid.Widgets.Add(button);
            
            // Spin button
            var spinButton = new SpinButton
            {
              Width = 100,
              Nullable = true
            };
            Grid.SetColumn(spinButton, 1);
            Grid.SetRow(spinButton, 1);
            grid.Widgets.Add(spinButton);
            
            // Add it to the desktop
            _desktop = new Desktop
            {
                Root = grid
            };
        }

        protected override void DrawCore(RenderContext context, RenderDrawContext drawContext)
        {
            // Clear depth buffer
            drawContext.CommandList.Clear(GraphicsDevice.Presenter.DepthStencilBuffer, DepthStencilClearOptions.DepthBuffer);
           
            // Render UI
            _desktop.Render();
        }
    }
}

It would initialize Myra and create basic 2x2 grid with some widgets.

6. Place MyraRenderer.cs in the same folder that contains MyGame.csproj. MyraRenderer.cs should appear in the Code:

7. Edit Assets/Graphics Compositor and MyraRenderer to the Entry points:

8. Run the project.

9. Myra UI should appear on top of the scene:
