Title: CPChessNet [developing]
Post by: Joseman on 01:36, 03 March 18

Here it is!!

CPChessNET 1.6b

http://www.cpcwiki.eu/forum/programming/cpchessnet-(developing)/?action=dlattach;attach=25021

[old]
Hi

I have been working on a Chess program for the CPC.

The idea is to use the M4 to connect 2 cpc via tcp/ip and the people can play chess all over the world!

At this point I can start to code the Net part of the program, the problem is that i have no idea.

The game doesn't use firmware, doesn't use ints, only pure (sloppy) asm :)

@Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624) can you help me with the m4 and the process to access the hardware to make a connection between 2 cpcs?

I never coded any client/server tcp/ip program, i suspect that with the M4 is easy... how can i start?

thankyou!

Good idea :)

@Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624) can you help me with the m4 and the process to access the hardware to make a connection between 2 cpcs?

I never coded any client/server tcp/ip program, i suspect that with the M4 is easy... how can i start?

Start by playing with the samples I made at:
https://github.com/M4Duke/M4examples

There's "tcp.s" which is a tcp/ip client. Run this on one CPC.
On another CPC run "tcpserv.s" which is a tcp/ip server.

This is the basics you need to transfer moves from one CPC to another. And probably the simplest method.
In your chess game, you would have to select if you want to be "host" (server) or join a server (be client).

You can also use the PC server (main.c) for some tests to understanding how it works. Advantage with that is you can install the awesome Wireshark program and monitor all packets closely.

Anyway have a look and I will be glad to help if there's anything.

hi @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

Thanks for the help!

seems very easy to make it, i'm trying it

one question,  when you read the buffer of the m4, how can you know the end of the buffer on every command?

thanks!!

(socket*16)+2    received: (2 bytes)    - data received in internal buffer (ready to get with C_NETRECV)

Once there is nothing in the incoming buffer (00 00)

Oh, interesting project! I'm not really updated what exactly is possible with the M4 and SymbOS. But maybe it's the best idea just to use all the Wifi-/Net-stuff from SymbOS instead of doing every thing new? - IIRC SymbOS 3 provides quite so great routines for Wifi-Connection.  :)


Yes, of course it's fun to code something by oneself!  :) :) :)

Yes, i've been waiting ages for the IDE program enviroment for symbos, years later, i've decided to code on plain asm :)

The error codes are:
-1      Out of memory error.   
-2      Buffer error.           
-3      Timeout                 
-4      Routing problem.       
-5      Operation in progress   
-6      Illegal value.         
-7      Operation would block. 
-8      Address in use.         
-9      Already connected.     
-10     Connection aborted.     
-11     Connection reset.       
-12     Connection closed.     
-13     Not connected.         
-14     Illegal argument.       

So you get -4, routing problem!

Don't know what you do wrong, without seeing the code.

Remember to always close a socket, even if you have an error or you will have to power off/on M4 to free it, maybe that's it ?

@Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

finally i did it!

i have 2 cpc connected (or so they say  ;D )

The thing is... they don't connect always

the cpc server seems to display my connected msg every now and then... but the cpc client always display my connected msg (even if the cpc server don't display it!)

i suspect that the cpc server get stuck on :

cp    4    ; incoming connection in progress?
jp z,wait_client

i say "suspect" because is a PAIN to code totally blind when you have to debug the m4 code  :laugh:

what do you think is the problem?

when i have to close socket?

thankyou!

At this point, it may be a good idea to use the pc tcp server example for testing, it's easy throw in debug output there to make sure everything is going is it should from the client side.

No idea with the current information, sorry :)
Quote

When you are done using a socket and the connection is no longer needed or an error occurred and you want to create a new socket.
There is only 4 sockets, so if you run the same test on cpc without closing the sockets (or power cycle) you will run out.


Btw. to compile the PC tcp server on windows, just install MinGW and copy main.c + makefile into a dir and type make

OMG i made it!!!

it was blood, sweat, and tears programming the M4 almost blindly!!

But i made it, client/server and the first transmisions (their nicks!).

is the first time that i start to believe that cpchessnet can be made!

Hi @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

One question, i have a little chat on the game, if i send a msg from the client to the server, but the server is checking the game parts, the client will wait forever for the server to receive the msg...

how can i tell the M4 to send the msg, and just continue with his things on the client side?

i suspect that this part of the code is the key:

Code: [Select]
wait_send:    ld    a,(ix)
            cp    2            ; send in progress?
            jr    z,wait_send    ; Could do other stuff here!
            cp    0
            call    nz,error_envio   

i don't want to "wait_send" just put the message out and continue...

maybe i need to do a variable called "message_pending" and if message_pending=1 then retry the send ony 1 time? make my things, retry another time...if message send then  "message_pending=0"

i'm learning for the first time client/server programming and i'm a little lost!

thankyou!!

You don't need to wait around for the message being sent, but you must just make sure it is sent before sending the next message.

Hi again @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

I think that some questions are more related to client/server aplications, hope this thread can be useful for another people  :laugh:

For example:

When you stablish a socket, do this socket need to be "renewed" some times? or keep alive? or when you stablish the socket, it remains forever stablished?

and this commands: cmdbind, cmdlisten, cmdaccept. they are sent to the M4 only one time? (stablish socket part).

I mean, first stablish socket, ok then later in the code, after do "chess things", at the end of the loop, only need to do wait_client and wait_recv, or only wait_recv. Or i have to do again cmdbind, cmdlisten and cmdaccept?.

Sorry for so many questions, it think i'm near to understand all, but is just that now it doesn't work correctly

Thankyou!
Title: Re: CPChessNet [developing]
Post by: Duke on 17:30, 06 March 18

You do not need to renew a socket, unless there is a disconnection. In that case you will need to close the socket and create it again.
On server side you *can* get away with keeping the socket and wait for a new incoming connection, but it may be safer to close the socket and re-do it all.

In your chess loop, you do not need to wait for anything unless you see something in the buffer.  Anyting in buffer ? if yes, wait recv, if no continue game loop.

Hi again again @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

I think i have sorted the problem...

when i can interchange nicks, before it the socket is  in status 4 (wait incoming)

but, when i enter the game, and try to receive a chat message from the client, the socket is status 0 (inactive)

how can i put the socket in wait incoming?

"wait incoming" is for establishing a connection to the host, after connection established you will only need to check if there is something for you:
(socket*16)+2    received: (2 bytes)    - data received in internal buffer (ready to get with C_NETRECV)
Check this in the socket status, if there is anything, use C_NETRECV.

Hi (again) @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

Right know i have a chat between the 2 cpc's

what i do is:

key t --> open chat ---> enter message --> send message to the other cpc --> update the chat_buffer on local  with local message -->repaint chat

on the other side: wait for a message --> yes? ---> move message to chat_buffer on local --> repaint chat

The thing is... what about if the other side don't receive the message (by a net error) but i update my local chat?

on a local net, there isn't virtually errors, and the chat works very well... but on Inet.. what do you think?

do i have to make sure the other side received the message? before update the local chat?

and if the other side didn't receive the message just send it again?

@Joseman (http://www.cpcwiki.eu/forum/index.php?action=profile;u=135)
If the other end did not receive the message (even if send was succesful). You could add your own handshake.

Ie one side send a message "hello other guy", now make a counter a long with the message ie. 01,00,"hello other guy".
In the other end if it receives the message, it would reply 01,00,"OK" or something, so you check for confirmation on the side that is sending, that it's actually received.
Have a timeout and if it doesn't get a response, re-send the message.

Of course always check for disconnection on the status and go through the entire re-connection process if so.

Errors can occur that will lead to a disconnection, check the error codes I pasted earlier.

2 cpc + 2 m4 (and a router of course), it can be in local lan on your house or internet around the world (untested XD)

ok

today i achieve board send between the 2 cpc's and turn change

right know the 2 cpc's knows the white moves and what is the turn (white move or black move)

i'm afraid that i'm not programming any check on connection errors, in lan works well, on internet... well we will see...

now i'll return to do the piece moves and when all white and black moves are done, the first beta will be released

i need to program the "board reversal" too, who plays with black will play with black on the bottom, who plays with white will play with white on the bottom too, but i think that only repaiting in accordance whith this is enough, the move code is the same after all... isn't it?

Hi

At this point all the piece moves are done...

The castling too (minus the possible check)

next is the check, checkmate and En Passant.

If i don't forget anything, the game will be done when this things are completed.

Title: Re: CPChessNet [developing]

Hi!

ok, the check ('jaque' in spanish) is 100% done, the 2 kings always knows  if they are in check by any piece in any place of the board.

this will allow me to complete the castling (they cant do castling if any walk of the king to make the castling is in check)

at this point  playing a chess  game is totally possible (only lacking checkmate (you can't do anything if checkmate but the game doesn't stops), em pasant and promotion)

Soon the first beta (i think)

Takis

The game has to work on a plain 464 (even from cassette), i only tested in a 6128.

Yes, i started to put the messages in spanish because the first idea of the program was to play with a good friend of mine from here. But it will had english text too. anyway chess itself and 2 more keys doesn't need any language  :) .

Hi

OMG the 'en passant' move was a hell to code, i didn't expect that!

https://en.wikipedia.org/wiki/En_passant (https://en.wikipedia.org/wiki/En_passant)

you can only use the en passant move if the enemy pawn makes a double-step (to avoid your pawn) and you ONLY can do the move in the next turn!, if you don't see it, the next time you cant make the 'en passant' move!, AND if the enemy pawn didn't do double-step (he reach with a 1+1 move) you need to control that your pawn don't make the 'en passant' move!!!!!

with the complexity of the move  i have no other choice that make 2 tables for the status of the pawns and send 1 table to the other cpc via net with the enemy pawns that are 'en passant' in the next turn, if we don't do the 'en passant' move (or is not possible) the 2 tables are reinitiated and so on...

the problem once i made the initial code, was to debug it, we have two possible bugs, on the move code itself (and trust me there were bugs) AND the possible bugs on the LAN code (and trust me there were bugs), the problem with the lan/m4 code is that you have to do all BLIND. i only have 2 functions to test the LAN code, one changes the border, and the other display the last stack entry (handy to display what values has a variable, a register... simply do 'push de : call check_stack' or ld a,(de) :push af: call check_stack'... as you can see hell in earth!!  :laugh:

Title: Re: CPChessNet [developing]
Post by: Joseman on 17:00, 16 March 18
Hi

...And for the ones who thought that coding the 'en passant' move was hard, the next chapter: coding the checkmate detection.

with the checkmate code i can assure you one thing now: i know why nobody coded a netchess on cpc before... it is a hell, trust me a HELL to code it.

hours and hours and hours (and hours) of debugging the checkmate code...

there are many ways for the detection of checkmate, but they do more or less the same (or so i have read): you do all the possible moves of your pieces in the next turn and if no move can prevent your king for being in checkmate you're lost.

i approach  the move a little differently, i look in the 8 directions of the king (plus the knights moves), while i look step by step i save the steps on an array, if any direction is in check, i end the function with carry activated.

if carry is activated (king in check) i already have the steps of the enemy piece to achieve the check condition. Next i move the king in all 8 directions and check (again, because the check function can be called separately) if in any direction the king is not in check, if any direction prevent the king for being in check (and the king can move to that direction), then there is not checkmate. But if the king can't move in 8 directions, next i look for all the pieces of my color in the board (minus the king) and try to intercept the check seeing the array of steps of the enemy piece, if any of my pieces can do the move, then this means that at least one of my pieces can 'eat' the enemy piece or put itself on the way to checkmate (with the knight only can 'eat'). BUT there is a last check! if we can intercept the check, but there is a double check (2 pieces threating the king) then our king will be still in check!. we have to double check the check condition intercepting one piece and seeing if the king is still in check!! in that case is checkmate

Ok, one thing is to say that and other thing is to CODE that... and trust me you DONT WANT to code something like this!!  :laugh:

anyway checkmate code is finished and working (or not if any bug still remains).

this means that the last move that can prevent cpchessnet to see the light of day is DONE.

now only a little more and game finished (i hope!)

Wow, sounds complicated! How long does the checkmate detection take to run?

they are easy calculations (a lot, and hard to debug), the cpc is almost idle with the game XD, even i have to slowdown the keyboard detection, if i detect the keyboard keys in every game loop, the pieces are almost impossible to select because the cursor is too fast, even you don't see the cursor when you press the keys because it is doing the same moves 100 times or more in one key press!

This is really an interesting project. Do you intend to release the sources once it is done?


As for you complex "check mate" code, this is typically the kind of code that would benefit from Z80 test units so that you can be sure your code works as expected and won't break as the code progresses. But maybe you've done so.

As I kid I was very interested in chess at one point. So I wished for one of those chess computers for Christmas one year.

17 years later I beat it!

Yea... it's safe to say I'm no expert chess player.  :)

CPC networked games is intriguing. Using the CPC for e-mail and IRC and a few games is intriguing. But in order for it to succeed, a lot of people have to have their CPC setup for Internet. So you can sit on IRC on #cpc, and go "Hey! Anyone up for a game of CPChessNet?" and 5 people will go: "Me!"

Oh, that gives me an idea: Could it be made possible to have spectators for a game?

Hi

Pawn Promotion done!

This was a easy one! only intercept the pawn_move rutine with is the pawn on the last line? then call pawn_promote, change the piece type for what is selected on the pawn promotion menu and ret to pawn_move

As for you complex "check mate" code, this is typically the kind of code that would benefit from Z80 test units so that you can be sure your code works as expected and won't break as the code progresses.

to be honest... i don't have idea of what Z80 test units are! if you can explain...

is not impossible to allow more clients to connect only to repaint the board on his side... but @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624) can tell us if there are limits on the number of clients conected!

But i think that only watch a chess game must be a hell of boring! and anyway the chat is only 3 lines, i have no more room for it... i don't know if it makes any sense. i'll be happy if the game works 100% correct, and i know for sure that actually it doesnt  :laugh:

Maybe the real interesting thing is to make a pc client, to allow to play chess with non cpc users... but i don't have patience to make a pc client right now!

if anyone wants to do a pc client... only have to read a little table with the board pieces and send it back when the move is done.

 OR better!! some emulator with M4 emulation!!!

to be honest... i don't have idea of what Z80 test units are! if you can explain...


It's a code, that you run from time to time, that will call some other code and checks that the result is fine. Let's say you have a multiplication code:


Code: [Select]
MultiplyBy4
  add hl,hl
  add hl,hl
  ret

To make sure that this code works, and will continue to work, you will make another code that will do this:
Code: [Select]
ld hl,10
call MultiplyBy4
;Checks the result: must be 40.
ld de,40
or a
sbc hl,de
jr z,OK
;Error!


You can do such code for all small subcodes, or on larger scale. For example, your test unit could:
- Create a chessboard (in memory) with a checkmate situation.
- Call the "isCheckMate" call
- Make sure the result is "true".


And you would create as many situations as possible to make sure the checkmate code works for them (and also for situatiosn where the checkmate returns false). Now, with such code, you KNOW that you checkmate code works, even after you make the checkmate code evolve.


Of course, it takes time to make such code, but it is extremely valuable to be sure that algorithms work perfectly; now and later.

Hi

Castling move finished, now the kings can't do castling if any of the square that the king needs walk to do the move is in threat. Fixed 1  (serious) bug in the routine too.

At this point i can tell you that all the moves & all the rules are finished, CPChessnet is almost finished.

I'll do a win/lose screen and the options to restart the game or go to the main menu, make the net code more reliable and the game will be uploaded for all who wants to betatest the game!.

Hi @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

I'm looking again the net code, and there is a problem with the connection...

if i setup the server, put it listening for a client and only after of this setup the client, the conexion works well, BUT

if i setup first the client and put it listening for a server and after of this, setup the server, the conexion doesn't work NEVER

what can i doing bad?

And other question, this is from the start, but never looked back again until the game is nearly finished...

my client/server cpc's create a socket, but i never close the sockets, the first time they choose 01h, if i reset the cpc, they choose 02h and so on...

what is the correct way of closing a socket, and this way the cpc's always use 01h?

thankyou for all !!

Check the status byte. You cannot connect to a server which does not exist so it should time out and give you an error.

When you no longer need the connection (say user exits), you simply close the socket you were given (ie. 1) and it will be available next time.
Also if an error occurs, you should close the socket and re-create it.

Thankyou @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)

to close a socket i understand that this is the code:

Code: [Select]
exit_close:
            ld    hl,cmdclose
            call    sendcmd           
            ret

but i cant see  where the number of socket to be closed is specified... maybe in the a register?

if i do this code alone (without specifying socket) sometimes it appears to close the open socket but other times it just freeze...

Yes, you need to send the socket number you want to close aswell.

Code: [Select]
cmdclose: db &03
dw    C_NETCLOSE
clsocket: db &0                <----------- put socket number here

You can also find parameters for all M4 commands here:

Yes yes, i read the documentation but for someone like me starting with M4 and protocols is a little hard to understand some things!

for example C_NETCLOSE is 2 times repeated with different ports, wich can be fine, but it's a little obscure, i didn't know what to use until i saw in your client code that C_NETCLOSE    equ &4333!

and "C_NETCLOSE Implemented v1.0.9.    data[0] = socket"

it took me a little while to understand that data[0] is
cmdclose:        db    &03  <---- data[0]
            dw    C_NETCLOSE

maybe it's just me, but maybe the instructions are a little advanced to people trying to understand whats goin' on with protocols, m4 and client/server applications!  :laugh:

It's not correct, this is how it works:
cmdclose: db &03           <---- Size of command+data to be sent
dw    C_NETCLOSE         <---- command (size 2)
clsocket: db &0               <---- data[0] (size 1)

Hi @Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624)


if i do this piece of code in my program:

Code: [Select]
wait_connect:

                        ;wait for ESC to press, if it's pressed then i do the cmdclose command
       
            ld    a,(ix)    ; get socket status  (0 ==IDLE (OK), 1 == connect in progress,
                                        ; 2 == send in progress)
           

                        cp    1 ; connect in progress?
            jr    z,wait_connect
            cp    0
            jr    z,connect_ok
             jp no_connect


I'm waiting for ESC to press to go back to the menu, while the bucle wait_connect is made...

when i hit esc, i go to a sub that performs the cmdclose command and jump to the main menu.

But not always returns to main menu, sometimes it returns, but sometimes is just hangs on the cmdclose command (i know it because i change to red border just after the cmdclose command, and because if i disconnect the M4 from power it goes back to the menu!)

Why is the M4 hanging in the cmdclose (but not always)?

on the no_connect jump i jump back to the cmdconnect command continue to the wait_connect command

can i call the cmdconnect command as many times as i want or there is a limit, or is supossed to call only one time?
Title: Re: CPChessNet [developing]

Do you store the socket number when you open it, so you are sure you are closing the right socket?

You are only supposed to call it one time. Of course if it eventually gives an error code, you can jump to it again, but as long as it returns "connect in progress" (1), you should not send a connect command again.
Just read status byte and check when it is connected (or error occurs).

yes, on the server and on the client, just when you save the socket on (csocket) i save it to another variable (using_socket), when i go to close de socket
i do ld a,(using_socket) ld (cLsocket),a --> cmdclose

one question:

if i do

            ld    hl,cmdconnect
            call    sendcmd
            ld    a,(iy+3)
            cp    255 ;#FF error
            jp    z,error_conectando_server

.error_conectando_server
 call 0

if i put an inexistent ip (192.168.0.50) i suposse that the cpc it's going to reboot

BUT it doesnt reboot, it reach the wait_connect bucle!

Also make sure that when you opened the socket, its a valid socket (1 to 4 ).

It will not know at that point, that the IP does not exist.
You will have to check the status byte from the read only address for the corresponding socket.

The 0xFF error only occurs, if the socket is out of range (less than 1 or bigger than 4).

almost i have it...

BUT

sometimes the cmdsocket command retuns '0' socket, if i understand is the local M4 not giving any free socket to the local cpc.

i compare that IF it's 0 then try to do another cmdsocket (without close anyting, i understand that at this point there isnt any conexion to close)

and again the m4 hangs in the cmdsocket :(, why?

sorry for so many questions and thankyou Duke.

CPChessNet 1.0b is reality at last!

*Net code is a lot stable now (connect/listen), not perfect, but very reliable,  there is no code to test if any conection lost occurs (i don't know how the game will perfom on internet)
*screen win/lose added, and the possibility of restart a game (it is tricky to assure that is correct, because of the thousands variables that the game is using, i don't know if there is any variable not initialice between games... time will tell)

very very soon the game on your cpc's to test.

@Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624), i suspect that there is need to open the router port 1234 for cpchessnet server?

Yes, if you used same port as the example it is port 4660 (0x1234). Also on the server you will need to forward the port to your CPC IP.

Hi

time has come!

Added the port option!

the default port is 6128  ;D

it was complicated for me to add a dec to hex port! i do in the nasty way, if you put 64321 i multiply 6x10000, 4x1000, 3x100,2x10,1x1, add all the result to a variable, then load the variable on a 16bit register (hl) and i do. ld de,#0000 , inc de, dec hl cp #0000, if not repeat bucle. at the end of the bucle, de has the hex por number  :laugh:

You can see the slowness of the routine if you put a high port, for example 60000, it take a while to go to the next screen!

oh, and is not the first time that i'm doing another things and found a bug on things that i thinked that it worked!!

this means that CPChessNET 1.0b has the 100% of possibilites to have bugs... take this on mind .

Here it is!

CPChessNET 1.0b for you.

REMEMBER to open the port 6128 (or whatever you choose) on the server router!!

I think that while CPChessNET is not free of bugs, better not upload it on your webpages or repositories!

The server parts of 8bitology.net are up and running. (I'm hoping Prodatron will adopt it soon too within Symbos). Only parts of the 8bitology.net GUI are not done, but they aren't required for in-game... only for web, and 8bml.

just enter to say that there is a big bug in CPChessNET 1.0.b

if you have a chat window open and the other cpc send the move, the move get lost, because in the chat window there isn't any comprobation if a message is received!

happen to Duke and I the other day, we were chatting for  15 minutes thinking that the other didn't do the move  :laugh:

Sure, you can use any value you want. It wont fill the buffer FF's unless its receiving them,

why if i still call wait_send: until i have a message i'm sending the board, the M4 just hangs after 10-15 calls to wait_send?

when i wait for a board confirmation, if the other cpc has a chat open, it will not send a message to the cpc that is on wait_send bucle, then the cpc that it is in bucle, just  hangs M4 on wait_send

It should not.
Anyway best practice is to put wait_send before sending, this way you are wasting less cpu time for the actual send.

Hi

CPChessNET 1.3b uploaded!!

fix:
*added board received check, no more boards lost on the infinite internet
*added chat byte ID, no more rubbish on the chat if someting goes wrong sending chat lines.

features added:
*added sound for move recived, you don't have to check for pal moves looking at the screen, just hear the sound!.
*the chat scan is less precise, so no repat letters are printed.
*added some chars for chat: ?, &, ! are now avaliable on cursors when chat is open.


as i can't prevent the M4 to hang when i do a bucle for receive a message, i added a timer, you have 20 minutes to have the window chat open and send a message. I don' think that anybody is going to spent 20 minutes to send a line chat!!, but if you do, the m4 willl hang! take care of this!

If a chat message is send or received between a board send, the board has priority, the line chats are omitted.

Please update to 1.3b and use the same version on client/server!!

and another game that i lost!

the board now is 100% safe to reach the other cpc and this is the most important.

the chat... mmmm i'll think more on it...

take in mind that there is still not check for connection losts!

if a cpc is turn off or lost the connection the other cpc will wait forever for the board!  :laugh:

@Duke (http://www.cpcwiki.eu/forum/index.php?action=profile;u=1624) what do you think is the timing to wait and realize that the connection is lost?

Should there be a dedicated IRC channel for people to meet on in order to arrange games? Maybe on FEFnet or Freenode or something?

I just thought meeting through an IRC channel could be done more in real time, rather than posting a forum message then waiting for someone to read it (which could potentially happen days later). Having that "live chat" aspect of IRC means you can instantly (usually) see if anyone else is available for a game at that same time.... well, it worked for scrabble players  :-\

trust me that on twitter the people is reading constantly (even at work)  :laugh:

if not, the problem will be the same on IRC, if people is at job or not in home the problem is the same!

So.... I've recently rediscovered #cpc channel on freenode IRC servers.
If anyone want to try CPChess with me I could be hanging out in there waiting. Or alternatively message me on the forum so we can arrange a time.

@Joseman (http://www.cpcwiki.eu/forum/index.php?action=profile;u=135) will there be an english language  version of the interface forthcoming at a later date?

I should also mention, I am terrible at chess and haven't played in at least 20 years ;)

ok!

time for 1.6b version!!

*this version has HUGE improvements in the chat code, no more chats lost in favour of a board move, first i do the move, next i see if any message is pending to receive or send. This was really hard to make it work!! I hope there is no problems! Only it can lost a message if a board is send and casually the chat message is lost on any packet on internet, but i suposse is difficult that happens.

*Little sound for the chat receive message, same as board move, you don't have to stay looking at the screen waiting for a move or chat.

*Now you can chat in the end screen, you can laugh at the loser or arrange another game!

KNOW PROBLEM:

*if a chat window is open when the end game ID is sent the end game ID gets lost (same as happenned with the board move on 1.0b version), this is for the same reason, no end game ID confirm is send back... No big problem at all... one side will display the end screen, the other simply will can't do anything because the king is on checkmate, the code will not allow to do anything on this situation, only to chat, and this is almost the same you can do on the end screen!.

*if the program has to check if any message is pending on the other side when it needs to send the board, then it will enter a bucle (that prevents the m4 to hang), it will delay 3-5 seconds...no big deal...


***as there is a lot of internal changes it can be some bug that didn't exist before**

play all you can!!

Yes, but i need to know that the program is almost 100% bug free before induce potential bugs on the char arrays changing the language!

anyway: cursor keys to move cursor, space to select/move. T for chat, enter to send chat. that's all

@Joseman (https://www.cpcwiki.eu/forum/index.php?action=profile;u=135) : I stumbled across CPCchessNet via the M4 board documentation. I like it very much. Its complete appearance is highly professional, even beautiful, I think. And of course, it works. Thank you for providing it!

Are you interested in a German translation? I offer to translate the texts if you send the English version of them to me in a file.

Hi
Thanks for the compliments  :)
The appearance is far from professional. The pieces are copied from Colossus Chess, and the texts are a simple font with that simple frames.
And it doesn't work always!! on local LAN it works without problem, but, on internet, if a packet is lost, the program waits forever for it... I never managed to fix that problem... If you chat a lot, you'll see the problem...
send me a mail to sjoseman@hotmail.com and i'll send you the text files
Regards

I have created most of a lobby system which I was hoping there would be some interest in it needs a first game... it also supports chat (email like).  Did you create a lobby yet? I also have achievement and leaderboards. At 8bitology.net

No, the game has a little chat integrated (that is the source of the problems with the packets lost), i ended tired of trying to fix that and the game is as is on the final version. On local lan never fails but on internet... well, the game can end stuck on a packet lost.
