Gideros Unite Framework

ar2rsawseen 2012/07/25 Gideros Mobile, updated 2023/12/13 (V2)

Gideros Unite framework provides a way to implement Multiplayer games:

  • using LuaSocket to establish socket connections and create server/client instances
  • device discovery over Local Area Network
  • call methods on devices through the network
  • protocols: tcp, udp or both (binding some method to tcp if reliability is needed, and others to udp for faster data processing)

You can download the Gideros Unite Framework: Unite.zip

And an application project: DrawTogetherV2.zip

Standard scenario

This is a standard scenario that can be created using Gideros Unite framework:

  1. Server starts broadcasting or skip to step 5, if all clients know server IP address
  2. Client's start listening to servers
  3. Client receives broadcast message from server, newServer event is initiated
  4. Client autoconnects to server or user manually (by pushing button) connects to specific server
  5. Server receives newClient event
  6. Server accepts client automatically or user manually (by pushing button) accepts specific client
  7. Client receives onAccept event
  8. Implement your game logic here, where both clients and server can call methods on all devices or on one specific device in the network
  9. When one of the clients becomes unreachable, all clients and server get onClientClose event
  10. When server becomes unreachable, all clients get onServerClose event
  11. When you are finished, close client or server using close method, which stops all timers, closes all connections and destroys instance

Client Method list

Constructor

Method name new(config)

Description Create client instance

Input parameters table config - lua table with configuration options:

  • string username - username to display on devices (default: hostname or device's IP address)
  • string ip - ip address to use for server (default: current device's IP address)
  • int tcpPort - port to use for tcp connection (default: 5883)
  • int udpPort - port to use for udp connection (default: 5884)
  • int discoveryPort - port to use for device discovery (default: 5885)
  • int multicast - multicast ip address for device discovery (default: 239.192.1.1)
  • int serverIP - ip address of server, if no discovery needed and can connect tp server directly (default: nil)
  • string connectionType - which connection protocol to use tcp, udp or both (default: 'both')

Example 

local serverlink = Client.new({
    username = "ar2rsawseen",
    ip = nil,
    port = 15000,
    multicast = "239.192.1.1",
    serverIP = nil,
    connectionType = "tcp"
})

Start Listening

Method name startListening()

Description Start Listening to server, both when server is broadcasting/multicasting for discovery, or when client is already connected to server (for example, by providing it's ip address)

Stop Listening

Method name stopListening()

Description Stop Listening to server, both when server is broadcasting/multicasting for discovery, or when client is already connected to server

Connect to specified Server

Method name connect(id)

Description When server is broadcasting/multicasting, if client is not yet connected to any server, it recieves new server events with server ID. You need to provide that ID to connect method, to connect to specified server

Input parameters int id - server id received from new server event

Example 

serverlink:connect(111222333)

Add Method

Method name addMethod(name, method, scope)

Description Add method which can be called through the network by other devices

Input parameters Input parameters are similar to adding new event listener

string name - name of command to associate with this method, could be simply method name as string

function method - method that will be called from other connected devices. This function will be called by other devices, and all parameters provided by other devices will be passed to this function. Additionally, the last providd parameter will be the source of message - id of device from which message originated

object scope - scope to use for method, if for example using class method and not simple function, you can provide self variable if defined inside class, of class instance if defiend outside class (default: nil)

Example 

serverlink:addMethod("draw", self.draw, self)

Call Method

Method name callMethod(...)

Description Call specific method for all connected devices

Input parameters string command - name of command, to call the method associated with this command

Other parameters can be any values, that will be passed to called method

Example 

serverlink:callMethod("draw", 100, 200)

Call Method of specific device

Method name callMethodOf(...)

Description Call specific method for specific connected devices

Input parameters string command - name of command, to call the method associated with this command

Other parameters can be any values, that will be passed to called method

Last parameter should be the ID of device, to which to send command

Example 

serverlink:callMethodOff("draw", 100, 200, 111222333)

Get devices

Method name getDevices()

Description Get ID of all devices connected to server. Due to limitation, that ID's of devices are retrieved through sockets on the network, this method does not return list of devices, but rather generates multiple "device" events, one for each connected device

Example 

serverlink:getDevices()

Close Client

Method name close()

Description Closes the client, disconnects it from server, disabled listening and erases ID. Serves as destructor for the class

Example 

serverlink:close()


Server Method list

Constructor

Method name new(config)

Description Create server instance

Input parameters table config - lua table with configuration options:

  • string username - username to display on devices (default: hostname or device's IP address)
  • string ip - ip address to use for server (default: curret devices IP address)
  • int tcpPort - port to use for tcp connection (default: 5883)
  • int udpPort - port to use for udp connection (default: 5884)
  • int discoveryPort - port to use for device discovery (default: 5885)
  • int multicast - multicast ip address for device discovery (default: 239.192.1.1)
  • int maxClients - maximal amount of clients server can serve (default: unlimited amount)
  • string connectionType - which connection protocol to use tcp, udp or both (default: 'both')

Example 

local serverlink = Server.new({
    username = "IAmAServer",
    ip = nil,
    port = 15000,
    multicast = "239.192.1.1",
    maxClients = 0,
    connectionType = "tcp"
})

Start Broadcasting

Method name startBroadcast()

Description Start Broadcasting to clients, both broadcast and multicast to discover other listening devices. Broadcasting includes listening, so if server is broadcasting, there is no need to call startListening method

Stop Broadcasting

Method name stopBroadcast()

Description Stop Broadcasting to clients

Start Listening

Method name startListening()

Description Start Listening to clients

Stop Listening

Method name stopListening()

Description Stop Listening to clients

Accept specified Client

Method name accept(id)

Description When client responded to broadcasting/multicasting message, server recieves new client events with client ID. You need to provide that ID to accept method, to accept specified client

Input parameters int id - client id received from new client event

Example 

serverlink:accept(111222333)

Add Method

Method name addMethod(name, method, scope)

Description Add method which can be called through the network by other devices

Input parameters Input parameters are similar to adding new event listener

serverlink:callMethod("draw", 100, 200)

Call Method of specific device

Method name callMethodOf(...)

Description Call specific method for specific connected devices

Input parameters string command - name of command, to call the method associated with this command

Other parameters can be any values, that will be passed to called method

Last parameter should be the ID of device, to which to send command

Example
