Explore the feature

  • Feature: Add Support for F# and VB Project Types: Stride now welcomes developers using F# and Visual Basic, offering support for code-only projects in these languages. This opens up Stride to a broader audience. Learn about F# and VB support

  • Stride Diagnostics Analyzer: This new tool provides immediate feedback within your IDE, identifying potential compatibility issues with Stride's serialization system. It's about making your development process smoother and helping you catch and resolve issues faster. Discover how it works, the docs page and here is the pull request.

  • OpenVR Handle Custom Resolution Specified by the User Through VR Settings: Enhancing VR development, this update allows developers to specify custom resolutions for VR projects, optimizing performance and visual quality for various VR devices. See the details

  • Editor Enhancements:

    • Dynamic Snapping for Selected Objects: This feature introduces dynamic snapping while transforming objects, improving precision and workflow efficiency within the Stride Editor. Dynamic snapping PR

    • Animation Stack Selection for FBX Imports: Stride now allows you to select specific animations from a stack when importing FBX files, giving you more control over the assets you bring into your projects. Learn more

    • Automatic Asset Copying to Resources Directory: To streamline asset management, the editor can now automatically copy imported assets to the project's Resources directory, ensuring your assets are always where they need to be. See how it works

A heartfelt thank you to all the contributors who have played a significant role in this release:

New Contributors

We are especially excited to welcome the following new contributors to Stride with the 4.2 release. Your contributions are greatly appreciated!

Stride 4.2 Feature Overview

F# and Visual Basic Integration

A pivotal PR has enabled F# and Visual Basic support for game development in Stride. This feature is currently limited to a code-only approach. Detailed insights and tutorials will be provided in upcoming blog posts.

We will use the Stride Community Toolkit [WIP], with further details to be covered in a separate post.

Below is a simple example of rendering a capsule using F#:

open Stride.CommunityToolkit.Engine;
open Stride.CommunityToolkit.ProceduralModels;
open Stride.Core.Mathematics;
open Stride.Engine;

let game = new Game()

let Start rootScene =
    game.AddProfiler() |> ignore

    let firstBox = game.CreatePrimitive(PrimitiveModelType.Capsule);
    firstBox.Transform.Position <- new Vector3(0f, 2.5f, 0f)
    firstBox.Scene <- rootScene

let main argv =
    game.Run(start = Start)

Example basic 3d scene with a capsule

The equivalent Visual Basic example:

Imports Stride.CommunityToolkit.Engine
Imports Stride.CommunityToolkit.ProceduralModels
Imports Stride.Core.Mathematics
Imports Stride.Engine

Module Program
    Private game As New Game()

    Sub Main()
        GameExtensions.Run(game, Nothing, AddressOf StartGame)
    End Sub

    Private Sub StartGame(rootScene As Scene)

        Dim entity = game.CreatePrimitive(PrimitiveModelType.Capsule)
        entity.Transform.Position = New Vector3(0, 8, 0)
        entity.Scene = rootScene
    End Sub
End Module

These examples showcase how F# and Visual Basic can be utilized in Stride. The Stride Community Toolkit provides a set of helpers and extensions designed to enhance your experience with the Stride Game Engine.


Although there have been many fixes, we'd like to point some of them out:

Also good to know

Although not directly tied to Release 4.2, we have some more big things going on.

For instance to our website and documentation. We also had another community meeting to address all those new members.


We extend our heartfelt gratitude for all the hard work and donations we have received. Your generous contributions significantly aid in the continuous development and enhancement of the Stride community and projects. Thank you for your support and belief in our collective efforts.
