    What have you done so far? Do you have code and any specific questions about your project?

    Sorry, no private communications.

    Write a SSCCE and post it here.

    Sorry, this defines a SSCCE: Short, Self Contained, Correct Example

    How will the client and server communicate? What messages will be sent between them? How can those messages be used to drive the playing of the game? You should be able to write the message sending/receiving code without having to work with the game playing code. Design an interface in the game code to use the messaging done over the network.

    SSCCE standards for Short, Self Contained, Correct Example. The post looks like the whole thing.

    For the networking part you won't need the whole thing.
    You should be able to write the message sending/receiving code without having to work with the game playing code. Design an interface in the game code to use the messaging done over the network.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Please edit the posted code and add proper indentations. The statements should NOT all start in the first column.
    Code inside {}s should be indented 3-4 spaces.

    Where? What post? The code in Post #9 needs to be fixed.

    What was the purpose of posting the code in post#9?

    Are you working on a design for the communications between the client and the server?

    yes......code #9 is the client/server program i coded.....so i need u to help me to make the #9 work with #7 two clients should be able to control their space ship over a network in realtime while both players can see the movement of each other's spaceships........

    What design items do you have so far for the communications between the client and the server?
    The code in post#7 will have to be rewritten to work with the network code.
    The networking code will NOT be part of the code in post#7.
    The classes and methods for the networking will be used by #7.
    There will be special drivers written to test the networking code before integrating it with #7

    what kind of drivers Norm? i normally run the client/server program from Command prompt in Windows......run the server first then client.....and then they both send/receive message vice versa........and what part of post #7 will have to be rewritten ?

    The drivers are simple programs to send and receive fixed messages for testing the network code. They would not be used after the testing.

    what part of post #7 will have to be rewritten
    The part that gets the input from the network instead of from a local user at the keyboard.

    What does the program need to get through the network communications to play the game?
    What response does the program need to make to a message received from the other player?

    For example:
    player1 moves his ship to x,y
    player2 says close but no damage
    player2 moves his ship to x,y
    player1 says you got me.

    Firstly I know coordinates is probably the wrong terminology? I'd assume i'd simply be passing the x and y variables, but coordinates describe it better I feel.

    Now I need to have a Server which can be accessed by 2 clients, it is a racing game and it requires each client to be able to maneuver a racecar simultaniously, each using a different control scheme but that's neither here nor there.

    I was hoping you would be able to assist me when it came to sending the x and y positions of a racecar to the server and having the server send them onto the next player and vice versa to allow both racecars to move at the same time on each clients window. So far i've only done the simple server stuff, such as the knock knock server on the sun website, and a simple echo server which repeats a string I send to the server.

    When I tried to use int instead of string I recieved an error that the int I wanted to pass was dynamic (obviously changes with each movement) and cannot be passed as static (using readInt and writeInt).

    So any help on how to create the wanted movement on both client windows through the server would be appreciated.

    Thanks

    Are you saying that the only thing a client sends to the server and the other client is two values: x and y?

    Have you designed and written any code yet?

    I recieved an error
    Please post the full text of the error message and the code. The code should be in separate classes with simple testing drivers to send and receive the data and show that is was sent and received.

    is not only X and Y........the space ship (player 1 ) is driven with W,A,S,D keys W to accelerate......A to turn left......S to decelerate....and D to turn right............so the objective now is to create a one Server to host two Client......the Server receives the keystroke from Client one and then send it to Client two and vice versa.....while the both Clients can see the movement of each other in realtime.......i did some research today i realised this can be done with "Serialisation " but i don't know how to implement that......i really need some help with this Norm...........

    First decide what data needs to be sent between the clients and the work on how to send it.
    Sending Strings is easier to debug. What information needs to be sent?

    The Server should be able to send ( co-ordinates, space ship crash and exit communications; concurrent controls)

    which i believe they are all integers.....

    Would the int values need any description? if "30,444" is sent, would the receiver know what that meant?
    Or would there need to be a descriptor: "moveTo 30,444"
