Hello dear AHK community. I should say that I'm just a beginner, I want to make a chess program with AHK. We have enough resources for that.
SKAN's PicturePuzzle0.9a is a very good example for board game makers.
I moded it for my needs, so to speak I plundered it :oops:

I have many problems to overcome now, I almost know nothing

My idea is to bind Crafty's DOS chess engine to SKAN's PicturePuzzle0.9a gui that I moded. For the time being I can move the pieces but I should apply rules to pieces such as castling for king and rook and diagonal moves for bishops and so on. I don't know how to exchange parameters between chess gui and Crafty engine. I even couldn't replace board background correctly

I trust you famous AHK coders, please help
Here is my project : http://www.autohotkey.net/~kenn/mychessproject.rar
to see the chess pieces click on board :cry:

P.S. Please don't laugh at me :oops:

I think Crafty implements the Winboard protocol - you could probably use that (works via stdin/stdout).

Roland, thanks for being so kind as to reply me. I began to feel that nobody was interested in my post. Did you take a look at my project? How can I replace board image behind the pieces?

Just use BackgroundTrans for the pieces (see docs for "Gui, Picture"). Plus you'll have to adjust the size of the background so that each square is the same size as a piece.

nice widipedia board and pieces! lol! i don't mean to make fun. honestly, i used those same pieces too for a while to print out problem sheets untill i started using chessbase instead! for me the quality of the image when printed 9 boards to a page on paper was the most important thing otherwise i'd still be using that!

anyways, i'm not much help but i'll do what i can! i'm excited to see your project and i hope it works out well! if you'd like we could maybe work together. i'm no good with most the ahk programming stuff but i can usually figure something out when i need to.

i have some chess tournament software i've been working on but it's not much (yet). if and when i ever get a descent program working and a website i'll put a download page for yours too if you want, so long as i'm able. here's the link to the page with the .exe and the open source, .ahk file. http://www.autohotkey.com/forum/viewtopic.php?t=66571 (my code's not anything super special but feel free to plunder away if there's something you think you can use).

p.s. i don't know if you've seen it yet or if it would help but there's a soduko .ahk script that's pretty interesting that might help you get some ideas.

Roland, thanks I ll try that. I need to look at examples especially ones move controls.

I know what you mean, I guessed somebody would notice that. thanks for your post and encouraging words. I want everybody to contribute to this project, we can have a working chess program. As I said I'm only a beginner so don't expect much from me but I'll do my best
By the way I knew your chess tournament program, It's nice, I was intent to use it for my chess club tournament

hmmmm... moving controls... now that you mention it i can't remember ever seeing any ahk scripts with any but that doesn't mean that there aren't any out there. i think it would be possible to make a gui window inside a window, possibly 64 of them, one for each square, and redraw the specific windows when triggered. but i've never dabbled with that idea so there's a good chance that's not the best way to go.

i've got a lot of controls in my script that i use for variables just let me know if you need any help with the kind of stuff i've put in my code. that's probably about all i'll ever be good for.

You can make 64 picture controls and assign a picture to each. Instead of moving them you can just change all the pictures to represent the current board state.

You will want to use the v option on each picture control so you can change it with GuiControl (see picture option).
You can use an array (see Object() in help) to hold the current board state and check possible moves.

I don't know all the rules of chess but I did have an idea for you. I've uploaded an example so you could look and see if it's close to what your looking for.

http://www.autohotkey.net/~specter333/Misc/Chess.zip

And here the script.

Code:

p1dis = square63
p2dis = square64

   GuiControl, Disable, %moveto%
   p1dis = %moveto%
   Return
   }
   
If pieceposy = %squareposy%
   {
   GuiControl, Enable, %p1dis%
   GuiControl, Disable, %moveto%
   p1dis = %moveto%
   Return
   }

MsgBox, This Piece can only move horizontally or vertically.`nPlease try again.
moveto =
selected = 
GoTo = selpiece
Return

For this to work you would have to be a math wiz and create a rule for every chess piece. I only made a rule for the "O" piece to move horizontally or vertically, the other piece doesn't move. I should also point out that I didn't make any rules for taking other pieces, only moving a piece around the board.

Notice each square's variable has it's position on the board, ie. square35 is x3 y5, this makes it easy to keep track of what square is being selected. Also every square the piece is sitting on when the game begins needs to be disabled and a variable assigned as to what piece is disabling (sitting on) so it can be enabled when the piece moves.

I think this will get you started if you can write all the rules for each piece and develop a method to change turns when a player moves. That last part should be easy, all the rules will be a challenge.

Good Luck

Is it a human vs human, or human vs AI?

A Chess AI for AHK would be thousands of lines long. One that is even worth playing that is.

Hello guys, I just had an opportunity to check out the posts, thanks a lot for your contributions, views and supports.

Spectre333, thanks for nice chess gui and idea, it's another approach to move the pieces, I ll check it out carefully.

tomoe_uehara, it will have both options, human vs human and human vs AI, remember we have free chess AI's such as Crafty, Rybka.. I put Crafty engine in my project, but we must implement it via stdin/stdout functions as Roland suggested.

Frankie, thanks a lot! Your tip is one of the best, I needed to know that. You grasped the essence of it, as to me you can lead this project, what do you think? Do you have enough time to spend on this?
