This is a work in progress xtra, as such some features are not yet fully operational. Here is the current status of each call: Complete features: (stable) GetLocalIP() -- Returns the IP address of the pc SendUDPMessage(ip, port, msg) -- Sends a string over UDP SendTCPMessage(ip, port, msg) -- Sends a string over TCP HasNext() -- Returns true if their are any messages received from UDP, TCP or HID USB GetNext() -- Returns the next message in the queue received from UDP, TCP or HID USB DestroyAllThreads() -- Stops all UDP, TCP, and HID communications WaitForUDP(port) -- Waits for a connection on TCP, DO NOT RUN TWO THREADS ON THE SAME PORT EVER! WaitForTCP(port) -- Waits for a connection on TCP, DO NOT RUN TWO THREADS ON THE SAME PORT EVER! GetListOfHIDDevices() -- Returns the VendorID, VersionNumber and ProductID of all HID devices connected to your computer. CheckWord(Word) -- Returns true if the word is spelled correctly GetSuggestions(word) -- Returns a list of words closely matching the specified word. INSTALLATION Simply extract and copy "TCPUDPXtra.x32" to your xtra directory of your Director Installation HOW TO USE ----------------------------------------------------------------------------- WaitForUDP (Object me, Integer PortNumber) DESCRIPTION: This function creates a thread that looks for UDP messages on the requested port. USAGE: object = new(xtra "ControlXtra") object.WaitForUDP( 1627 ) NOTE: To retrieve messages you will have to use getNext() and hasNext(). ----------------------------------------------------------------------------- WaitForTCP (Object me, Integer PortNumber) DESCRIPTION: This function creates a thread that looks for TCP messages on the requested port. USAGE: object = new(xtra "ControlXtra") object.WaitForUDP( 1627 ) NOTE: To retrieve messages you will have to use getNext() and hasNext(). ----------------------------------------------------------------------------- SendUDPMessage (Object me, String IP, Integer PortNumber, String Message) DESCRIPTION: This function sends a UDP packet containing your message to the specified port USAGE: object = new(xtra "ControlXtra") object.sendUDPMessage("192.168.0.100", 1627, "MY MESSAGE") ----------------------------------------------------------------------------- SendTCPMessage (Object me, String IP, Integer PortNumber, String Message) DESCRIPTION: This function sends a TCP packet containing your message to the specified port USAGE: object = new(xtra "TCPUDPXtra") object.sendTCPMessage("192.168.0.100", 1627, "MY MESSAGE") ----------------------------------------------------------------------------- HasNext (Object me) DESCRIPTION: This function returns true if their are messages that have not yet been processed. USAGE: on startMovie global object object = new(xtra "TCPUDPXtra") object.waitForUDP(1627) object.sendUDPMessage("192.168.0.100", 1627, "HERE IS A SAMPLE MESSAGE") end on enterFrame me global object if object.hasNext() then alert "THERE IS A NEW MESSAGE!!" end if end ----------------------------------------------------------------------------- GetNext (Object me) DESCRIPTION: This function returns any messages that have not yet been sent to director, or -1 if their is no messages. For USB it will return a string, for TCP/UDP it will return a message in the format [message, sourceIP] USAGE: on startMovie global object object = new(xtra "TCPUDPXtra") object.waitForUDP(1627) object.sendUDPMessage("192.168.0.100", 1627, "HERE IS A SAMPLE MESSAGE") end on enterFrame me global object if object.hasNext() then alert object.getNext() end if end ----------------------------------------------------------------------------- DestroyAllThreads (Object me) DESCRIPTION: Basically a closing parameter in this application, it ensures that the memory is cleaned of any remaining unread messages and closes all open ports that it was using. USAGE: on startMovie global object object = new(xtra "TCPUDPXtra") object.waitForUDP(1627) object.sendUDPMessage("192.168.0.100", 1627, "HERE IS A SAMPLE MESSAGE") end on enterFrame me global object if object.hasNext() then alert object.getNext() end if end on StopMovie global object if object <> void then object.DestroyAllThreads() end if end
