Connecting to wss://multiplayer.scirra.com ?

Hey hey,

I realised that sometimes it simply doesn't connect to the signalling server but other times it does. To clarify what I mean: "On signalling connected" doesnt trigger sometimes. Is this normal?

thank you

I dont know where it was posted, but Ashley mentioned there was a higher percentage incorrect connections then what you would get if you hosted and used your own signalling server. Thought it was roughly 10% ..

I have been fiddling with the wss scirra server a good bit in the last two days, so I have been the host for a number of people joining. I am trying to dissect the message structure that it uses to send messages back and forth in order to build a server capable of handling C2 multiplayer requests.

Here is what I have so far:

This is with my client as the host of the chat room.

Has anyone ever written any kind of guide on the API for the multiplayer in C2?

According to Stackoverflow, it looks like the Google STUN servers used for webRTC (on which C2 Multiplayer is based) are not 100% reliable. This would explain your not being able to connect.

I see. So buying an own signalling server wont really solve the problem .. thanks

Well, I imagine if you made your own signalling server, you could avoid the Google ones. C2 uses the Google ones since they are free and available. I am planning on using a centralized server to avoid the need for a signalling server altogether.
