Scratch

More like Chalkmarrow did it 

I probably wouldn't have figured out the correct commands.

I am going to try make a tag like game today using the networking features. I will upload the source files on to the scratch connections wiki when I am done.

Sure, but it will only work if you download the project to your computer. Also one person has to have the flash file running on their computer.

Magnie, if you want I can face you in a game of scratch tag when I am done coding it 

Hmm. I think you might have to have a separate dataInHandler for each socket.

I am having some problems with data transfer. As a test I tried to transfer the x position and it put it to the wrong values.

Here is the source http://www.filesavr.com/untitled-4

I tried this on 2 of my computers. It did receive and send an x position but I was the wrong value. So my sprite was moving but to the wrong x position.

That Would Be Awsome! But I Don't Think I Have Flash Needs To be .exe or .py I think.

The flash file is .exe

But only 1 of the 2 people actually need the flash file running anyways so all you would need to download is the project.

Ok    I Can't Wait. EEK

That's amazing. If you can pull that off it will be very impressive.I haven't had a chance to look at the .fla file you linked to, since I only have CS3 on one computer. But I'll look at it by tomorrow. What is the failure mode? Are the sensor variables being scrambled in  a consistent way? I'm assuming you're sending integers, though I haven't looked at the .sb file either...

Ah. Ok. I remember that when I was making my Processing program that interfaced with Scratch I had the same problem because the buffer filled up with sensor updates and broadcasts so fast that one or more of the programs couldn't keep up. Every broadcast and variable change gets sent out over the socket, so what I had to do was come up with a way to ignore the things I didn't care about. The buffer has to be cleared out as fast as possible. Though if the variable is only being updated every 1.0 seconds, I can't imagine that that would be a problem. I'll see if I can help puzzle it out.

Update: Can you cut and paste the script in plaintext? The .fla file is giving CS3 a problem ("unexpected file format").

Sure, but I also posted what should be a cs3 version as well.

My flash has 2 buttons, an input text field (for the IP) and 2 other dynamic text fields that state the status of the connection.

var mySocket=new Socket();
var friendSocket=new Socket();
var dataOut:String;
var player1Connected:Boolean;
var player2Connected:Boolean;
var player1X:String;
var player2X:String;
var player1Y:String;
var player2Y:String;
var test:String;
myStatus.text=String("Waiting to connect to your computer");
friendStatus.text=String("Waiting to connect to your friends computer");
var socketNum:int=1;
inputIP.text='192.168.1.103';

my_btn.addEventListener(MouseEvent.CLICK, enterMyIP);
function enterMyIP(evt:MouseEvent):void {
    socketNum=1;
    mySocket.connect("localhost",42001);
    mySocket.addEventListener(Event.CONNECT,socket);
    mySocket.addEventListener(Event.CLOSE,socket);
    mySocket.addEventListener(IOErrorEvent.IO_ERROR,socket);
    mySocket.addEventListener(ProgressEvent.SOCKET_DATA, dataInHandler);
}

ip_btn.addEventListener(MouseEvent.CLICK, enterIP);
function enterIP(evt:MouseEvent):void {
    socketNum=2;
    //192.168.1.103
    friendSocket.connect(inputIP.text,42001);
    friendSocket.addEventListener(Event.CONNECT,socket);
    friendSocket.addEventListener(Event.CLOSE,socket);
    friendSocket.addEventListener(IOErrorEvent.IO_ERROR,socket);
    friendSocket.addEventListener(ProgressEvent.SOCKET_DATA, fdataInHandler);
}

function socket(Event):void {
    if (socketNum==1) {
        switch (Event.type) {
            case 'ioError' :
                myStatus.text=String("Cannot connect to your computer");
                break;
            case 'connect' :
                myStatus.text=String("Connected to your computer");
                player1Connected=true;
                if (player1Connected==true&&player2Connected==true) {
                    SendToScratch('broadcast "StartGame"',1);
                    SendToScratch('broadcast "StartGame"',2);
                }
                break;
            case 'close' :
                myStatus.text=String("Cannot connect to your computer");
                break;
        }

    } else {
        switch (Event.type) {
            case 'ioError' :
                friendStatus.text=String("Cannot connect to your friends computer");
                break;
            case 'connect' :
                friendStatus.text=String("Connected to your friends computer");
                SendToScratch('sensor-update "Scratch-playerNumber" 2',2);
                player2Connected=true;
                if (player1Connected==true&&player2Connected==true) {
                    SendToScratch('broadcast "StartGame"',1);
                    SendToScratch('broadcast "StartGame"',2);
                }
                break;
            case 'close' :
                friendStatus.text=String("Cannot connect to your friends computer");
                break;
        }
    }
}
//sendToScratch('broadcast "StartGame"');

function SendToScratch(dataOut:String,playerNum:int) {
    var sizeBytes:ByteArray = new ByteArray();
    sizeBytes[0]=0;
    sizeBytes[1]=0;
    sizeBytes[2]=0;
    sizeBytes[3]=dataOut.length;
    if (playerNum==1) {
        mySocket.writeBytes(sizeBytes);
        mySocket.writeMultiByte(dataOut, "us-ascii");
        mySocket.flush();
    } else {
        friendSocket.writeBytes(sizeBytes);
        friendSocket.writeMultiByte(dataOut, "us-ascii");
        friendSocket.flush();
    }
}

function dataInHandler(event:ProgressEvent):void {
    var inString:String=mySocket.readUTF();
    //trace(inString);
    SendToScratch(inString,2);

}

function fdataInHandler(event:ProgressEvent):void {
    var inString2:String=friendSocket.readUTF();
    //trace(inString2);
    test=inString2.substring(0,39);
    if (test.charAt(0)=='s') {
        trace(test);
    }

    SendToScratch(inString2,1);
}
