Hi.

I'm new here and was wondering if anyone has tried PubNub to implement multiplayer in any of their Impact games?

Cheers.

wow, never heard of any service that handles back-and-forth connections like PubNub.... thanks for the link!

hmm if I wanted to start multiplayer, I would give isogenic engine a shot http://isogenicengine.com, since the function is already built in. Costs some money though.

try PubNub out yourself, and maybe report back to us here? That would be awesome

Hey fugufish, thanks for the link. Ill check it out.

I got PubNub messages sending and receiving no problem, the api is only a handful of calls. I was posting here myself for any feedback by anyone who has used it in a real-world app :)

I was also looking at some source over at the Corona SDK forum that does some lobby/room system that might make a great Impact plugin: http://developer.anscamobile.com/code/multiplayer-networking
- obviously uses the Corona PubNub api, but the logic is there.

For those interested, theres also a similar looking service called Pusher: http://pusher.com/
Looks more expensive, much better website though :)

Check out this post on Quora — the CEO/Founders of both PubNub and pusher weigh in:

I really like the real-time multi-touch demo. It worked well on the desktop and on my Android phone simultaneously.

Thanks ianl, i'll give that article a look over.

faye on node.js does the same .. and costs nothing if you got infastructure ..

and there are serveral implementations for that on github

Right, and there's also Socket.IO, which tries lots of different connection methods (WebSockets, Flash sockets, XHR polling, etc.) and has a few backends (Node, Python...)

In my experience:

• Socket.IO works best if you're using the NodeJS-based backend. The Python/Tornado backend gave us a lot of trouble but mostly works and is only compatible with Socket.IO < 0.7.

• PubNub seemed to connect and work flawlessly across modern browsers, IE7/8, Android and iOS.

• I couldn't get the Pusher.com example app to work.

• I haven't tried Faye but there's a good discussion on Stack Overflow here.

Apparently tylerappmobi did some work with pubnub

Nice! I'm going to play around with this now.

Thanks a lot.

@Jerczu
I did do some preliminary work with PubNub to see if they were a good solution for mobile HTML5 multi-player. I got a really simple game working but I had a problem with response time ( testing on an iPad 2 with OS 4.3.2 and a computer, I got a 1-5 second delay from button press). After I saw the performance I decided to move onto Pusher (websocket service) as it's faster than HTTP Streaming/Long-Polling.

I did do this all on my free time and would encourage you to see if you can get PubNub working in a better capacity. I need the service to be faster as I'm trying to find a multi-player HTML5 mobile solution and not just a HTML5 solution.

I have gotten a HTML5 chat client working using Pusher on an iPad 2 to an iPhone and a computer, but I haven't had time to convert this example over into making position update calls and create a multi-player game( Not enough free time :/ )

I'll update these forums when I get Pusher working to let you know my findings

Cheers
