1 i meet prob with crossdomain.xml, line on server.js:
io.set(‘transports’, [‘websocket’, ‘flashsocket’]);
fix this prob
2 but after meet prob (unknown transport, in unity - SocketIoClientConnection.cs:66) same as here:
i think, for support last v., can add in unity js file - sever:port/socket.io/socket.io.js then it will standart usable functions, but it not usable as it, need many fix, hard work…
I get it, this is old, but new products are available! Get Node-Red. Built in UDP input and output! Then all you do is attach a UDP sender or reciever to an object in a scene, and VIOLA!
Use REST APIs or web sockets to connect Node.js with Unity. need coding expertise and networking understanding. Tools from a third party can make the procedure easier.
