Dear all

I am currently building a browser based game and using html5 canvas, JavaScript, node.js and socket.io. I am currently building the multiplayer part and I have got a way of doing it but don't know the code. Please can someone write an, JavaScript file for client and a server file with socket.io, that follows this format.

When someone changes player location, client messages server to broadcast new location to all the other clients in same room

When someone joins room adds them to player list.

When someone changes their data number it broadcasts that to others in room to change the player list.

When some else leaves the room it tells client to remove them from player list

When you leave room it wipes the player list on client.

When the server is messaged with new players loc or stats it saves it in its own array or backs it up into a database

If you have any questions please let me know.



Here is an example of the array that stores player list of other players in room.

Players {
Name : "Username",
Locationx: 12, // limit of 40
Locationy: 6, // limit of 20
Stat1: 2,
Stat2: 7,
Stat3: 3,
Stat4: 9
}

Thanks for your time,
Thomas

Can some one reply???

All i need is to get the server to post to clients in the room a list of clients and their data when ever someone joins room or changes their data

Can someone reply, if i need to re-think this as this is a matter of urgency????

This is asking a lot, as what you are asking it not trivial. A better way to get help would probably be to post what you already have done and we can help with any problem pieces.

you have several options, either build the NodeJs client the same as your "class" above or pass that data to functions to your client to control. You can add any properties to your Nodejs client like a class. So add Name as a property to the client Id instance then you can find it via that property and make changes as needed. Simply pass the info back to the browser client to make the changes. Node has a Room feature that handles all that as well.

I have now dropped socket.io and using php to gather the player data, Currently it dumps the data into the html page like this: how could i do this so it sets this directly within the java script file

yes you could load direcly JSON from within JS... check out what jquery can do for example.

Remember that on the server-side (the side where your PHP lives and runs), Javascript is nothing but text. So you can actually use PHP to write Javascript. You can do something like this:

Is it possible if I could add this directly into my js file instead of having it in my html code??? Also what would I do when I want to update this, would I need to use a function as I need it to update other players data every second. I thought to use socket.io as you won't be using that much connections. I just wanted it to update when ever someone in the room moves, then broadcast to the room as it's more efficient

Yes, you will need to do it dynamically through Socket.io if you need the server to notify players who have already downloaded the page.
