Comments/Ratings for a Single Item

OK, I see that my trick did not work for swapping b and d, as these are same shade, so that the B must get automatically to opposit halves, and the : adds nothing extra. I changed the meaning of : now to explicitly mean "mirror-image location", and adapted the Diagram script for that. This should make your diagram work as you have it, with the updated script.

I'm not sure why but the diagram still does not work.

It behaves the same way.

I'm wondering if you have not tried to put a bishop over an already occupied square. Would this be an error?

I think caching again is broken on this website. I uploaded a new Diagram script, but when I read it back from the website, it shows the old text. Only when I suffix the URL with some random suffix, like ?t=1234, I get to see the newly uploaded text.

So this is what you can do as a work-around too: suffix the URL to betza.js in your comment to make it betza.js?nocache=true , to make sure it will use the new script. You still would have to flush your browser cache. When I tried the current script locally on your diagram, the shuffling works as it should.

BTW, note that when you specify symmetry=mirror (as you must, to preserve vertical symmetry during shuffling), there is no need to mention the location of the black pieces, as the Diagram would automatically add those. So you could leave out the double comma and everything behind it, even for the holes.

@HG,

Indeed HG, now the diagram works as expected for me too!...

Thanks!

@Fergus,

I have remade the code to work as expected for the king to not be able to use the special moves out of check:

/play/pbm/play.php?game%3DApothecary+Chess+1%26settings%3DApothecary1working

The relevant piece of code for white  is:

if flag f2:
if == moved K:
  if sub checked $origin:;
    if not or checkleap $origin $dest 1 0 checkleap $origin $dest 1 1:
    die A King may not use the special moves out of check.;
  endif;
endif;
endif;
endif;

There is still the problem that the special moves are displayed as legal when a king is in check. Is that solvable?

As long as you evaluate actual moves in the Post-Move sections, you have to bear in mind that potential moves are evaluated before a move would be made, and actual moves are evaluated after a move has been made. This means that you have to sometimes use different code for potential and actual moves. That's true of the King here. You should use both a function and a subroutine for the King's movement. The function should handle only potential moves, and it should stop a King from making its special move out of check before it makes its move. The subroutine should handle actual moves, and it should undo a King's special move after it has been made to make sure the King didn't move out of check with that move, then redo it if it was legal.

 have written the following code but I don't know where to call the subroutine.

sub King from to

    move #to #from;
    if sub checked #from:
    verify or checkleap #from #to 1 0 checkleap #from #to 1 1;
    else:
    verify fn King #from #to;
    endif;
    move #from #to;

endsub;

;

To the editors.

Can a piece set be changed or it needs to be redone from the beginning?

I want to change in the apothecary chess standard piece set the bird with the dragon.

Since your function has to allow special moves but stop the illegal ones, you should not be calling your function from your subroutine. They should be independent from each other. How to call the subroutine is described in the Fairychess include file tutorial under "A Real Example from Chess".

The tutorial also describes how you can use different pieces with the same notation. Although you cannot modify a set within Game Courier, you can change which pieces you use and what notation you will use for them. I recommend reviewing this tutorial every now and then.

While I could add code to Game Courier for enabling GAME Code programs to modify the images in piece sets, it would not work in Edit mode. So, if you want to use piece images that are not in your current set, you should change it to use a different set.

Fergus, 

I want to use the same set, not another one, but with a dragon picture instead of a bird picture. Is that even possible or should I make another piece set from the beginning?

Since you are using custom 'Apothecary' sets, and I doubt other games are using these sets, they can be altered.  Do you want to keep the notation the same?  ('A' becomes bird)  Or do you want to add a Dragon as 'D'?

I'd prefer the Dragon with a "D".

Ok, I have added D and left the A so older games will still view correctly.  If you are going to change the notation, remeber to change the name of the settings so that you don't break older game logs.

Thank you, Greg!

@Oisin D.

I need a moment with no ongoing games so that I can change the pieces from Griffin and Aanca to Dragon and Griffin, so please temporarilly delete your pending invitation.

You need to use a new Settings name so old games don't break.  But if you do that, the pending invite is ok.

@ Greg,

I prefer to keep the name  and maybe rename the settings files used for old games. Can it be done?

You can keep the name of the game, but the settings name will need to change.  I don't know how to change the settings name for existing logs.

I should use redirect then on the old settings file toward the new one, isn't it?

@HG, Hello, The interactive diagram on this page puts in the initial position an extra black joker outside of those defined. Why is this happening?

I have played this game against the interactive diagram's AI. It takes less time that an game courier match and I wanted to see how the games feel after the final changes I have made. The game seems to be very tactical now with many strong pieces quickly engaging . I'm really unsure about how good the game is. It's learning curve is quite steep but maybe once properly learned it is fun. I was hoping that more experienced player will take a look and try to play against the interactive diagram until the endgame (me I always blunder something before the endgame).

I have switched the places of sangoma and wizard in the opening position in order to give more opening opportunities.

I have tried this week to add a compound piece. Unfortunately this proved to make the game worse as more opening moves were forced. So I reverted to an earlier version while keeping the idea that black has more pieces on the non-king side. This will be the final apothecary chess-modern game. I'm satisfied with the game.
