Welcome to the Stride Game Engine

Stride is an open-source C# game engine designed for realistic rendering and VR. Highly modular, it aims to give game makers more flexibility in their development. Stride comes with an editor, Game Studio, which allows you to create and manage the content of your games or applications visually and intuitively. To learn more about Stride, visit stride3d.net.

This README is intended for users who want to build the Stride engine from source or contribute to its development. If your goal is to create games using Stride, we recommend visiting the Get started with Stride guide. There, you'll find detailed instructions on downloading, installing, and getting started with game development in Stride.

🛠️ Building from Source

Prerequisites

1. Latest Git with Large File Support selected during setup. For convenience, you might also use a Git UI client like GitExtensions.
2. .NET 8.0 SDK
   • Run dotnet --info in a console or PowerShell window to see which versions you have installed.
3. Visual Studio 2022 (the Community edition is free) with the following workloads:
   • .NET desktop development with .NET Framework 4.7.2 targeting pack (should be enabled by default)
   • Desktop development with C++ with:
     • Windows 11 SDK (10.0.22621.0) or a later version (should be enabled by default)
     • MSVC v143 - VS2022 C++ x64/x86 build tools (Latest) (should be enabled by default)
     • C++/CLI support for v143 build tools (Latest) (not enabled by default)
   • Optional (to target iOS/Android): .NET Multi-platform App UI development and the Android SDK setup individual component (enabled by default). Then, in Visual Studio, go to Tools > Android > Android SDK Manager and install NDK (version 20.1+) from the Tools tab.
   • Optional (to build the VSIX package): Visual Studio extension development

[!NOTE] The installation of Visual Studio with the required components may require up to 14 GB of disk space, depending on your system and selected components.

[!WARNING] If this is your first time installing the .NET SDK, you might need to restart your system after the installation so that the system can recognize the new environment variables.

Build Stride

1. Clone the repository using a Git UI client or from the command line:

   git lfs clone https://github.com/stride3d/stride.git
   

2. Open the solution:
   • Open <StrideDir>\build\Stride.sln with Visual Studio 2022.
   • Build the Stride.GameStudio project in the 60-Editor solution folder (it should be the default startup project) or run it directly from Visual Studio's toolbar.
   • Optionally, open and build Stride.Android.sln, Stride.iOS.sln, etc.

[!WARNING] Do NOT use GitHub -> Code -> Download ZIP option, as this won't include the LFS files.

Build Stride without Visual Studio

1. Install Visual Studio Build Tools with the same prerequisites listed above.
2. Add MSBuild to your system's PATH:
   • Add MSBuild's directory to your PATH environment variable (e.g., C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin).
3. Clone the repository:

   git lfs clone https://github.com/stride3d/stride.git
   
   

4. Build using the command line:
   • Navigate to the /build directory in the command prompt and run:

   msbuild /t:Restore Stride.sln
   
   

   • Then run:

   compile.bat
   
   

If Building Fails

• Some errors for test projects are normal, GameStudio will start anyway.
• The Visual Studio extension might fail to build if you are missing the Visual Studio SDK, but Game Studio will start anyway.
• If you skipped any of the Prerequisites thinking you already have the latest version, please update to the latest to be sure.
• Visual Studio might have issues building properly if an older version is present alongside 2022. If you want to keep those versions, ensure they are up to date and that you are building Stride using Visual Studio 2022.
• Your system's PATH should not contain older versions of MSBuild (e.g., ...\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin should be removed).
• Some changes might require a system reboot. Try that if you haven't yet, for example, if you see these errors:
  • Could not find a compatible version of MSBuild.
  • Path to dotnet executable is not set.
• Ensure that Git, Git LFS, and Visual Studio can access the internet.
• Close Visual Studio, clear the NuGet cache (dotnet nuget locals all --clear), delete the hidden .vs folder inside \build and the files inside bin\packages, kill any msbuild and other Visual Studio processes, then build the whole solution and run GameStudio.

[!WARNING] Test solutions might fail, but this should not prevent you from building Stride.GameStudio.
