2 players game via Bluetooth in Gideros

Mells

Hi,

I often see that multiplayer games are possible via bluetooth (Street Fighter Volt, Metal Slug 3, etc).
How hard would it be to add this ability in a game made with Gideros?

I have checked the Gideros Unite framework but it seems to target different needs.

So I'm asking : Has anybody done it successfully?

Thank you

atilim

As an another question, are these games using multiplayer capabilities of Game Center to communicate via bluetooth? Does somebody know?

@atilim I can't speak for those games in particular, but I figure that'd be an easy way to do it regardless. Game Center Multiplayer would be so amazing, I can't even begin to describe it. hehe (Sorry...not a helpful comment, just putting in my vote)

Talking about online games,which is your first choice -game center or custom server?
I my opinion, game center is much easier but in the long run custom server would be the first choice, although write a server from the ground up requirs a lot of work.

So, any idea on the next step to take it further?

atilim

Still I need to read GameKit (Game Center) documentation to understand the possibility and workload of implementing bluetooth multiplayer capabilities. But in any case, it won't be available with the next version.

Monday again @techdojo? Have you read the first post?

) @techdojo, that will teach you to read the whole thread )

Damm - yes it's monday, personally I find reading to be an overrated (and much underused) skill "> "> ">

ha @techdojo

@atilim Thanks for the answer. If you ever come up with some informations about it, please keep us updated (even a "very low priority item" would be informative).

Apart from some client needs, that's a feature that I would really need to make a multiplayer game than I plan to be playable with airplay on big screens.

AutoLAN might be something you could adapt. It's written in LUA for another mobile LUA dev environment. I'm not sure about how to tie it to bluetooth - but if you can get at it maybe the logic in that could be used.

Has anyone tried AutoLan in Gideros?

@OZApps reviewed autolan for C sdk
maybe he knows the answer for you

We have been playing with the gamekit plugin code today and have so far got it to

• Show the bluetooth peer picker when gameKit:btConnect() is called
• Dispatch an event when the Peer Picker is cancelled which can be caught in gideros using gamekit:addEventListener("peerPickerCanceled", onPeerPickerCancelled)

We are now implementing the session:peer:didChangeState: method to detect when a user is connected.

We'll keep you informed as we work on this and hopefully @atilim will either merge our gameKit plugin with his or replace it with ours when our bluetooth implementation is complete.

Quick update

You can now
• Connect to other devices using peer picker
• Recieve event when peer connects using gamekit:addEventListener("peerConnected", onPeerConnect) Event passes PeerID as string
• Recieve event when peer disconnects using gamekit:addEventListener("peerDisconnected", onPeerDisconnect) Event passes PeerID as string
• Send string to other device using gamekit:btSendString(stringtosend)

SimpleLoop

Code is up on github now if you want to have a play.
This is only bluetooth currently but we are planning to add support for the other Gamecenter multiplayer features.
There is still a lot to do as some things are not released properly and tables can currently only contain strings.

Here's the link:
https://github.com/SimpleLoop/GamekitMultiplayer

And here's a list of what we have working so far

---------------- Functions ----------------
gamekit:btConnect() -- Show Peer Picker
gamekit:btDisconnectAll() -- Disconnect Peers

gamekit:btSendString(String) -- Send String
gamekit:btSendTable(luaTable) -- Send Table

---------------- Listeners ----------------
gamekit:addEventListener("peerPickerCanceled", functionToRun) -- Peer Picker Cancelled
gamekit:addEventListener("peersDisconnected", functionToRun) -- All Peers Disconnected

gamekit:addEventListener("peerConnected", functionToRun) -- Peer Connected [Passes Variables event.peerID as string]
gamekit:addEventListener("peerDisconnected", functionToRun) -- Peer Disconnected [Passes Variables event.peerID as string]
gamekit:addEventListener("peerUnavailable", functionToRun) -- Peer Unavailable [Passes Variables event.peerID as string]
gamekit:addEventListener("peerAvailable", functionToRun) -- Peer Available [Passes Variables event.peerID as string]
gamekit:addEventListener("peerConnecting", functionToRun) -- Peer Connecting [Passes Variables event.peerID as string]

gamekit:addEventListener("recievedData", functionToRun) -- Data Recieved [Passes Variables event.data as table if table recieved, event.dataString if string recieved]

Releasing has now been fixed and works correctly.
github has been updated with the new version.

@SimpleLoop thank you very much for sharing.
With my limited skills, I hope I'll be able to make it run in my current game.
Thank you again for the work done.

DRS

@SimpleLoop thanks!
I will also give it a try with my limited skills. (
Very inspiring.
