Chu Seireigi. Variant of Chu Shogi playable with drops. (12x12, Cells: 144) [All Comments] [Add Comment or Rating]
H. G. Muller wrote on Thu, Apr 25 03:02 AM EDT in reply to François Houdebert from Wed Apr 24 05:15 PM:

I guess the drop model still needs some tweeking. The square painting on the hand ranks should be the same as that of the other hand squares. Now there seems to be no coloring at all, so that the rim texture shines through. I suppose the logical way to do this is that the square-painting array that has to be defined in the game's view file should include the extra ranks.

It is also not clear to me why the 'counter piece' in the lower-right corner is larger than the others.

[Edit] The array boardLayout defined in the view file is accessed in two places in grid-board-view.js, inside nested loops over rows and columns. The loop over rows was modified to skip the extra hand ranks. I suppose this was a bad idea; especially in the 'paintCells' function it should have run over all ranks, requiring the boardLayout to also specify how the cells in these extra hand ranks should be colored. There is a second routine 'paintInCoordinates' that also loops over all cells, which does more complex things and might need more subtle modification than just changing the loop limits. But it seems this function is not normally used.

The handLayout[-1] in the view file appears to have a 16 where there should be a 17, which causes misplacement of the 'counter piece' on 15 rather than 16.

No, you have to write something like

Model.Game.handLayout[1] = [0,2,4,6,8,10,12,14,30,46,62,...];

if you want the first 8 'hand squares' for white to be at the bottom, and the rest along the right edge.

The issues that the Tinkercad website is having recently may lead me to take a break after this weekend. Since the problem mainly affects new uploads, I may continue for a short while, but otherwise I'll just wait for the problem to be fixed.

I had already planned on only going to #366 (I'm running out of possible pieces to post), posting only occasionally afterward for extensions of sets, missed rotary counterparts, special requests, new discoveries, and so forth. I also had planned, if I hadn't done this already by then, to take the time to create an index of sorts that I could post as an article.

281. Mei (Chinese Rose / Rao). If a Nao is a Chinese Nightrider, then could there be a Chinese Rose? Well, of course there could! Like the Nao, the Mei (the best translation into Chinese for the word "rose" that I could find*) moves without capture normally, but must jump over a hurdle to capture. It's just that the Mei moves like a Rose. (mqNcqpN)

I don't think a move diagram is needed in this case, since most of us here knows how the Rose moves. I can vouch that the above XBetza does work; I tried it out in the XBetza Sandbox, and it behaves just as intended.

As I was informed in a later reply, this piece is called a Rao by chess problemists.

Creating this led me to discover some serious design flaws with my original Rose piece, which I've now corrected on my own system and will upload some time soon (Thingiverse is still having problems.)

*I have no doubt -- and, in fact, much hope -- that someone well-versed in the language will correct me if I got it wrong.

It's good to know that you can use the bottom squares for that. Does it mean that we have to specify something like Model.Game.handLayout[1][{2:18,4:17}]; // eg : square 2, hand 18 for the white for each piecetype?

H. G. Muller wrote on Wed, Apr 24 09:51 AM EDT:

Note that it is possible to control the way the captured pieces are placed next to the board by defining arrays Model.Game.handLayout[color][handIndex]. This array should contain the square numbers where you want the first captured piece of the given color (1 or -1) and hand value to be placed. (A second piece will be placed at sqr+color, and after that counters will appear between the two shown pieces.)

Currently the default assignment is used, which places the white pieces on the first 'file' on the right of the board, the hand number equal to the rank number (which starts at 0). By defining a handLayout you could also use the ranks under or above the board to place pieces, thus requiring fewer extra ranks.

E.g. with a single extra rank (instead of the 4 you have now) you could place 6 white pieces below the board, and 14 white pieces to the right of the board.

Thanks.

Can you also do the same for normal Seireigi? It has the same problem with its 3d Kanji pieces.


H. G. Muller wrote on Wed, Apr 24 04:33 AM EDT in reply to A. M. DeWitt from Tue Apr 23 04:34 PM:

There appears to be a mismatch between the shogi graphics on CVP and that in the current source code. On CVP there are directories .../chessbase/res/shogi and .../chessbase/res/shogi2. The first contains the tile meshes and diffusemap for mini-Shogi, the second for Chu and Tenjiku Shogi. The current source code was derived from the latter, even though it reorganized the location where the diffusemaps are stored.

The problem occurs because the newly made Seireigi diffusemaps are made according to the Tenjiku design, (and placed so the view files can find them), but use the mini-Shogi tile mesh files. And it appears that these mesh files specify the use of a different part of the diffusemap for painting the top face: the mini-Shogi tiles use the top-left quarter, while the Chu-Shogi tiles use the bottom-left quarter of the maps.

I fixed the problem by editing the chu-seireigi-view.js file, to make it use the mesh files from the shogi2 folder. The kanji then appear. But apparently not all mesh files used by seireigi are there, as some of the pieces now disappear completely.

[Edit] The problem was in the map files: some Seireigi pieces use the diffusemap of Chu-Shogi pieces, and these are in a different location on CVP from where they are in the current source code (and have different filenames too). I adapted the path for the diffusemaps of Copper, Kirin, Phoenix, Lion and Queen to where these images are on CVP, and now the initial position of Chu Seireigi is correctly displayed.

Talking about background it doesn't seem to work on my device even though it used to work. Interactive Diagrams that use backgrounds like Eurasian Chess, Chak, VaoQi don't seem to have backgrounds on my device.


H. G. Muller wrote on Wed, Apr 24 03:02 AM EDT in reply to HaruN Y from 02:49 AM:

I beat you by 4 minutes! :-)

It is interesting how we both chose a different rectification of the board; mine spoils the coordinates, yours spoils the moves of the pieces. In your representation it would in principle be possible to use a whole-board image as background that has the original diamond-shaped cells.

I tried using the Atlantic SVG set through fen2.php, but this set is not suitable for use on a black-and-white board. (Alfaerie doesn't do so well either, on the dark squares...)

[Edit] Concerning Pawn: Ah yes, I had overlooked that detail in the description. Thanks!

This is an excellent concept. There's just one tweak I'd like to see. Pawns on the a-file cannot move any further to the left, so that could be a problem. One way to remedy that might be to divide the board vertically down the middle, giving pawns on files A-D a move to the RIGHT, and on files E-H to the LEFT, as you have currently done for all pawns.

280. Yak. No, this isn't another Tifinagh piece*; this is named for the animal.

It simply occurred to me recently that particularly large boards could use a piece that's the equivalent of a Buffalo (NCZ), extending one space further. I considered naming it for a pouncing predator, but besides most such creatures being already taken, it didn't seem to fit the established pattern. This piece combines the leaps of the Knight (horse), Camel, Zebra, Giraffe, and Antelope, and also includes many compound ungulates (Gnu, Bison, Okapi, Buffalo, and so forth), so an ungulate seemed fitting. After a little bit of research, the animal that stood out was the Yak. (NCZFXNY)

I deliberately excluded the (4,2) leap of the Hare/Stag/Lancer since it's just an extension of the Knight move; pieces that add the DY or N2 can be considered separately. As it is already, it can be a formidable and versatile piece.

*The two forms of the letter yak are ⴽ and (in Tuareg) ⴾ, neither of which (in my opinion) make particularly good chess pieces -- at least, not without some sort of mirror image.

For some reason, the 3d graphics for Seireigi and Chu Seireigi are only showing as blank Shogi pieces, and in the case of certain Chu Seireigi pieces, not showing at all. Any help would be greatly appreciated.

Also, I noticed a bug in the Hectochess file, where, when castling, the Champion starting square is not checked to see if a piece is there or not.
