Syntax highlighting and Language Server support for Photon Quantum3 DSL (.qtn) files, including autocomplete, go-to-definition, hover information, and symbols.
Syntax highlighting and Language Server support for Photon Quantum 3 DSL (.qtn) files in Visual Studio 2022, including autocomplete, go-to-definition, hover information, and symbols.
.qtn is the data-definition language for Quantum's deterministic ECS — it declares components, structs, events, signals, inputs and globals that the Quantum code generator turns into C#.
Language Server features — autocomplete, hover information, go-to-definition, and symbols across your .qtn files.
Document & workspace symbols — navigate types and members quickly.
Requirements
Visual Studio 2022 (17.0+)
The extension bundles its Language Server and a private Node.js runtime. No separate Node.js installation or PATH setup is required, even for Unity/C# projects. No runtime download occurs at startup.
The VSIX is larger because it includes the runtime. If IntelliSense cannot start, syntax highlighting remains available; check Output → QTN Language Server for details and update/reinstall the extension.
