LUBE (Networking Library)

[Davidobot]

I don't think there is one for tcp, and there probably isn't one for enet, but for udp it's 64k.

Thanks!
Using LUBE, how would you make the server run via tcp, because (correct me if I'm wrong) by default it runs udp?

Code: Select all

server = lube.server(globalIP, globalPort)
server:setCallback(onReceive, onConnect, onDisconnect)
server:setHandshake("abc")

Well, you're using an old version of lube.

Well, you're using an old version of lube.

Okay, thanks

just from copy/pasting the example code given, i'm given this error when i attempt to run it (good idea to right click/copy link location to see the full error). currently using 0.9.0. is it incompatible with the new version?

No, as far as I know LUBE is a pure lua library (and it works here)

Okay, here's the thing: LUBE uses [wiki]Class Commons[/wiki]. That allows libraries to use OOP without depending on any specific class implementation. To use it, you need a class library that is compatible with Class Commons (like Slither or [wiki]MiddleClass[/wiki]).

hi
version 0.7 i got working fine.
but version 1.0 is very different, and i just can't get it to work at all

globals :

Code: Select all

_ip = "127.0.0.1"
_port = "18025"

server code :

Code: Select all

function StartServer()
    server = lube.udpServer()
    server:listen(_port)
    server.callbacks.connect = onConnect
    server.callbacks.recv = onReceive
    server.handshake = "Hi!"
    print("created")
end

client code :

Code: Select all

function StartClient()
    client = lube.udpClient()
    client.handshake = "Hi!"
    client.callbacks.recv = Receive
    success, er = client:connect(_ip, _port)
    print("success : " .. tostring(success)) 
    return success
end

regardless if the server is running StartClient() is always successful - I assume this is due to the nature of udp being connectionless ? (maybe?). Or should it only connect to a port that is being "listened" on ? If this is so.. then I have no idea why/how it always connects successfully.

the main problem is, in the server code i have

Code: Select all

function onConnect(id)
    print("Connected : " .. id)
    server:send("hi")
end

"Connected : ip:port" gets printed to my log so that's all good.
but server:send("hi") is NEVER received by the client

inside LUBE.lua, it fails here

Code: Select all

function udpClient:_receive()
	local data, ip, port = self.socket:receivefrom()
	print(data)
	if ip == self.host and port == self.port then
            return data
	end

        print("data " .. tostring(data))
        print("ip " .. ip)
        print("port " .. tostring(port))
        print("self host : "..self.host)
        print("self port : "..self.port)

	return false, "Unknown remote sent data."
end

console window:

nil
data nil
ip timeout
port nil
self host : 127.0.0.1
self port : 18025

What am I missing here ?

[bartbes]

Does your server run the update method or the receive method?

[zell2002]

yea
in LUBE :

Code: Select all

function server:update(dt)
print("server update")
-- more code
end

function udpServer:receive()
print("server rec!")
local data, ip, port = self.socket:receivefrom()	
print("data : " .. tostring(data))
-- more code
end

both these functions run
data is always nil

You're not supposed to override them, you're supposed to call them.
