There is a UnitySocketIO solution out there, however i do not believe it is working properly with current unity versions.
I am able to connect to a node.js server but the unity client CPU goes through the roof…
Unfortunately i am not experienced enough to update it myself (not even close for that matter )
Therefore i am crying out for help, hoping someone can update it for us…
Requires POMELO which breaks down to socket.io or websockets.
I only had a quick look at it testing the chat demo chatofpomelo (server) with pomelo-unitychat (client) and it worked ok for me after revising some of LoginGUI code. You can find details about what to change in the pull request on Git. You can ignore the missing mono behavior errors.
Has anyone done anything really worthwhile with Node.js and Unity? Seems more like a novelty item.
