Hello

My understanding is that websockets run over TCP, therefore being much slower than webRTC which supports the UDP protocol.
Typically realtime games use the UDP protocol instead of TCP, is there a chance to make this work in this library ?

Thanks

Hi,

I am running the Box 2d demo at this url

http://hulea.org/RealTimeMultiMover/DemoBox2DApp.html

However the is empty?

Any reason for this

The only errors that I am getting is this

I am not getting any errors in console ?

Thanks for any pointers you may have

Hi,
congratulations for this framework, but especially for having released as open-source.
I'm starting to use your framework for the construction of a multiplayer game (or at least I try).
I did some initial adjustment to adapt the framework to the latest version of socketio.

the "constructEntityDescription" In "GameEntity" allows for "wantsFullUpdate" but then not used within the function.
"If true, Certain Things That are only sent When changed are always sent"
You have commented.

What can I do about this parameter?

Another related problem is that I would send over the network initially and then only when asked for a full "EntityDescription" to initialize the object (bodymass, bodyfriction, geometryWidth, geometryHeight etc. ..)
Then inside the loop send a simple "EntityDescription" that contains only "position, rotation and id .."

• I have to edit the source of the framework, or is already prepared for this?
• It is connected with "wantsFullUpdate"?

I hope I was clear and I apologize in advance for my English "google translated"

I believe the js/lib/circlecollision is outdated from your CirclePackingJS repo. There it is fixed, but in this repo CircleManager.js should be

// Wrap X
if(boundsRule & wrapXMask && xpos-diameter > this.bounds.width) {
aCircle.position.x = this.bounds.x - radius;
} else if(boundsRule & wrapXMask && xpos+diameter < this.bounds.x) {
aCircle.position.x = this.bounds.width + radius;
}

Currently they are both " - radius" so the circle will appear to jump on the right side when you navigate your player through the left boundary.
I want to say thanks for releasing this its really great for getting started making a multiplayer game.

The instructions in the readme are very vague.

"run the server and brows to "/DemoHelloWorld.html"

On localhost? What port? I can just open the file DemoHelloWorld.html, but then it will be on a different origin from the websockets, causing it to print this:

14 Nov 23:57:57 - Initializing client with transport "websocket"
14 Nov 23:57:57 - WebSocket connection invalid or Origin not verified
14 Nov 23:58:02 - Initializing client with transport "xhr-polling"
14 Nov 23:58:02 - Client 03701277635991573 connected
1 joined the game!

If you want to use websockets, you have to be on the same origin, right? So you should have your server serve up this static file. And you should be clear about where your server is serving it to. It does not print out the client port to the terminal, and it took me a bit of hunting to find where that is even set.

Hey,

I'm not able to run this step:

5. Within another terminal, navigate to the root directory and run "python -m SimpleHTTPServer"

Can you please elaborate?

I followed the steps in the readme, it seems as though it is not working. I followed the error and it looks like it has something to do with socket.io failing to connect?

The package.json in the root doesn't specify a licence. A licence should be chosen for the project 🍔

I'm trying to follow the simple 3-step instructions, but I'm running into some trouble.

The server starts and outputs the normal message:

$ node js/DemoCircles/server.js
29 Jul 00:31:22 - Your node instance does not have root privileges. This means that the flash XML policy file will be served inline instead of on port 843. This will slow down initial connections slightly.
29 Jul 00:31:22 - socket.io ready - accepting connections

But when I try to load the demo (in Safari or Chrome), nothing happens. The browser appears to connect (as the loading spinner runs until I ctrl-c the server), but no more console output appears, and nothing appears in the browser(s).

I've tried connecting to a variety of URLs (I'm assuming the default port of 8081 is correct):

http://localhost:8081/RealtimeMultiplayerNodejs/DemoCircles.html
http://localhost:8081/DemoCircles.html

Any help? Am I missing any dependencies?

How can i handle keyboard events. Do you have any examples?

Thanks.

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

Hi,

how are you supposed to start the demo? The documentation just says: 'Browse to "/DemoHelloWorld.html"' but on which server or port or just with file://? I tried

http://localhost/path/to/DemoHelloWorld.html (via my local Apache)
file:///path/to//DemoHelloWorld.html
http://example.com/path/to//DemoHelloWorld.html (Apache on the internet)
http://localhost:8081/DemoHelloWorld.html (Port from js/model/Constants.js)
http://example.com:8081/DemoHelloWorld.html (Port from js/model/Constants.js)

The description suggests that this would be perfect for what we try to do (a multiplayer server/client game with node in the browser) but it seems not to matter what I try to get the demo up and running (I even tried it as root as one other guy suggested), either nothing happens or I get the error:

Hello Mario,
there is some form of client-side prediction in the framework?

I thought about putting some kind of prediction based on user input in "constructEntityDescription" of "KeboardInputTrait" (transformed for my needs "KeboardMouseInputTrait") just simply processing user input and waiting for the next "SERVER_FULL_UPDATE" overwrites the "world state".

constructEntityDescription: function (gameTick, wantsFullUpdate)
{
this.processInputNow ()
return {
EntityID: this.entityid,
Input: this.input.constructInputBitmask (),
inputLook: this.input.constructInputLook ()
}
},

processInputNow: function ()
{
this.attachedEntity.updatePosition ()
this.attachedEntity.updateLook ()
this.attachedEntity.updateFire ()
}

Do you think that is a correct method?
There are better ways?
You're the only person who can help me, thank you anyway!

What about a demo using JSNES?

If it sounds like a good idea, I'm up for doing some/all of the work.

FYI: I've cross-posted a similar issue just to get some more feedback.
