Socket.IO in unity5 ,C# - how to emit string or object?

Question

I'm new to C# and unity. I'm trying to send a simple string to the server using Socket.IO:

socket.Emit("collision", "Surface") It doesn't work, i get:

I tried a bunch of things, the following code works only with strings as numbers:

var dataToSend = new JSONObject();
dataToSend["colider"] = new JSONObject("2"); // this works..
socket.Emit("collision", dataToSend);

the following gives null - third one in the image below..

var dataToSend = new JSONObject();
dataToSend["colider"] = new JSONObject("Surface");
socket.Emit("collision", dataToSend);

Thig gives empty object { }

var dataToSend = new JSONObject();
dataToSend["colider"] = new JSONObject(JsonUtility.ToJson("Surface"));
socket.Emit("collision", dataToSend);

I get:

So how can i send/emit this "Surface" string to the server? Why is it so hard, it's just a simple string .. ?! thank you:)

Answer 1

I found it: socket.Emit("collision", JSONObject.CreateStringObject("Surface"));

There are a bunch of more specialized functions - the API can be found inside SocketIO/JSONObject/JSONObject.cs - for the Socket.IO library downloaded from assets store
