View source for Godot-Mono

{{Expansion}}Godot-Mono is [[Godot]]'s game engine supporting C# language for creating both 2D and 3D games.

== Installation ==
Add <code>pkgs.godot-mono</code> (GDScript + C#) to <code>environment.systemPackages</code>.

== Export Templates ==
On Godot upgrade, the new export template version can be automatically provisioned this way:

<code>home.file.".local/share/godot/export_templates/${builtins.replaceStrings [ "-" ] [ "." ] pkgs.godot-mono_4-export-templates.version}".source = pkgs.godot-mono_4-export-templates;</code>

Note: `pkgs.godot-mono_4-export-templates` package is still pending in nixpkgs.

== Configuring VSCode Editor for Godot-Mono (C#) ==
As Godot editor has poor support for C#, VSCode editor is recommended.

Install and configure VSCode as such:
 programs.vscode = {
   enable = true;
   package = pkgs.codium;
   profiles.default = {
     "godotTools.lsp.serverPort" = 6005; # port should match your Godot configuration
     "dotnetAcquisitionExtension.sharedExistingDotnetPath" = "${pkgs.dotnet-sdk_8}/bin/dotnet";
     "dotnetAcquisitionExtension.existingDotnetPath" = [
        {
           "extensionId" = "ms-dotnettools.csharp";
           "path" = "${pkgs.dotnet-sdk_8}/bin/dotnet";
        }
        {
           "extensionId" = "ms-dotnettools.csdevkit";
           "path" = "${pkgs.dotnet-sdk_8}/bin/dotnet";
        }
     ];
   extensions = with pkgs.vscode-extensions; [
     geequlim.godot-tools # For Godot GDScript
     ms-dotnettools.csdevkit
     ms-dotnettools.csharp
     ms-dotnettools.vscode-dotnet-runtime
   ];
 };
