Hi Mario

Great work btw! I just downloaded and installed the node.js v0.6.13 mac port.

I'm getting some startup errors do I need to nph install something? I'm new to node.js.

Toms-MacBook-Air:RealtimeMultiplayerNodeJS Tomo$ node js/DemoBox2D/server.js 17 Mar 12:16:30 - socket.io ready - accepting connections

node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: listen EACCES at errnoException (net.js:646:11) at Array.1 (net.js:732:28) at EventEmitter._tickCallback (node.js:192:40) Toms-MacBook-Air:RealtimeMultiplayerNodeJS Tomo$

Oh just noticed this has to be run as root!

Can you note in the docs where I can change the ports? Thanks.

Hi Tom, can you fork it and adjust the docs to reflect your findings as you've tried to get it running? I feel that there might be other things i omit on account of being 'used to' setting it up.

That would be a big help

tomoprime commented 12 years ago

I forked it. Where can I change the port numbers?

For some modifiable options

I saw the videos on your work which is pretty cool. I would like to see how Websockets could be integrated into Unity. Atm the Box2D demo is eating 50% of cpu with no users connected...

Btw did you hear that Unity3d is giving away free licenses of iOS and Android which expires April 8th 2012. https://store.unity3d.com/index.html

Hi tomoprime, ah interesting usage!

The Box2D demo might eat a decent amount of CPU regardless of how many users are connected since there are many objects and they're all colliding with one another. However due to the way V8 works, as the server and code runs the Optimizing Compiler starts to find functions that are candidates for optimization and re-implements them so the simulation gradually runs better and better as more time goes by.

I did hear about that and i signed up the day of right on the spot! That's great to hear that the AT&T how to go plugged, although they did a terrible job and ruined ( ignored? ) any formatting suggestions I made.

I believe the websocket implementation has been updated, so I have to update the socket.io version I'm using in the engine. I will do that today

or just change port :) It worked for me as shown in my last post : http://blog.i-evaluation.com/2012/10/20/angular-js-error-listen-eacces/
