Trying the demos

Each demo needs its server running on a specific port (so they don't clash):

Demo Server port Run server Run client
Chat room 5187 cd examples/chat-room/ChatRoomServer && dotnet run Godot → main menu → Chat Room
Guess the word 5188 cd examples/guess-word/GuessWordServer && dotnet run Godot → main menu → Guess the Word
Login / Register 5189 cd examples/login-register/AuthServer && dotnet run Godot → main menu → Login / Register

Open the Godot project at godot-example/, then run the main scene.

Using the plugin in your own project

  1. Copy godot-example/addons/GDSignalR/ into your project's addons/ folder.
  2. Enable GDSignalR in Project Settings → Plugins.
  3. Use it:
var hub := HubConnection.new()
add_child(hub)
hub.on("ReceiveMessage", func(user, text): print(user, ": ", text))
hub.connect_to_url("ws://localhost:5000/chatHub")
await hub.connected
hub.send("SendMessage", ["Godot", "Hello!"])
var result = await hub.invoke("GetData", [])

  • Repository version → tag (v1.0.0)
  • The asset library will fetch the repo and use the addons/ subtree.
