CVP – The Most Complex Variant of Chess Yet

ss+(2017-09-08+at+11.44.56)This took a really, really long time…

Well, things have been slow, and the time I have to spend on this project is growing shorter, but another milestone has been hit. Since the release of v0.1, my main focus has been on creating the Sovereign Chess variant, and I’m happy to say that all the hard features are finally complete. All that’s left now is some simple housekeeping, and the castling mechanic (which is frustratingly unintuitive with my interface). But it feels real good to have all these complex mechanics work together as intended, as you can see above. And from the questionable amount of testing I’ve done, I’ve yet to encounter any bugs. So that’s good.

Aside from the behemoth, I’ve implemented several other variants that are closer in-line with the rest of the family so far. I selected ones that didn’t involve any unimplemented mechanics just so that I could pump out as many variants as possible during the long haul of Sovereign Chess development. Since, well, even though it is complicated, I want the next release to contain more than just Sovereign Chess. Speaking of which, once the variant’s completely finished, I’ll definitely get the next version of the game up and available as soon as possible, which ideally will be very soon.

On a further note, I’m just gonna refrain from listing the new variants and chess pieces each post, and instead have them listed together with the next release of the game — just so these intermediate posts are more compact and focused on the process of development rather than the changelog.

CVP — Proper Pawn Promotions, More Variants, and a Download Link!

chess-variant-player v0.1 is now available! Download link for the latest version is under Categories -> Downloads.

Finally got around to setting up proper pawn promotions. I avoided it for a while and just let pawns automatically promote to queens, but as I added more and more variants that altered pawn promotion rules, it was becoming painful to ignore. Just a testament to how much I dislike working with Unity UI I guess; really does my head in sometimes.

There are a few rules that the program doesn’t account for yet: three-fold repetition, insufficient material, and closed position stalemates. Other than that everything should be working as intended.
Note that there isn’t any UI for when a team wins or stalemates yet — instead neither team will be able to move a piece once the game is over.
Of course this will be properly implemented in the future.

Although not completed, development on variant Sovereign chess is ongoing and should be released in the next public build. It’s by far the most divergent chess variant from FIDE rules than any of the other 28 variants implemented, but is still a very interesting game and just looks amazing (still need to add the lines dividing the board).

Features down the line include descriptions for each variant, as to a curious but unknowing user it may be confusing as to how each variant differs from the last. So it’d be nice if they could learn about the variants right then and there instead of googling it, or in the case of Sovereign chess, an in-game link directly to the large set of new rules.

CVP — Fairy Pieces, Git, and More Variants

ss+(2017-07-13+at+04.44.38)

Managed to set up version control with Bitbucket and Sourcetree, along with Unity’s cloud build system for the project. It apparently caches the library files after each build so there are less files to commit and push to the remote repo, while also being able to routinely build the project if a change is detected, so that’s convenient. Since the builds are available in zip format online, I’ll see what I can do to provide a link for the latest build here.

Since the last post, new content includes:

I’ve also implemented functionality for chessboards that aren’t rectangular in shape, though I’m not sure of many variants that involve these types of boards (aside from Omega chess).

There are still plans for many more variants, but I’m aware that there are many more than I would like to spend time implementing. So at some point I’ll implement a sort of ‘create-a-variant’ option to allow users to create their own variants including customizing board size and shape, initial piece positions, piece rules, and winning conditions for each team. That’s a bit further down the line, and would require a lot of UI. So the next update or two will continue to focus on more variants and fairy chess pieces.

A Tool for Playing Chess Variants!

Since March of 2017, I’ve been working on a chess program with the intent of implementing as many variants of chess as I can. Unlike my previous projects, this is the first project that is “unoriginal”, in the sense that it is an already-known and understood game. I would like the final product to be a chess player that allows the user to select between a large variety of chess game-modes to play with. Since it’s a tool, only local 2 player/single-player is supported.

Currently implemented modes of play:

Wikipedia’s list of chess variants has been my go-to for implementing each variant’s setup and rules. No plans regarding game modes with board sizes that aren’t rectangular, but I will be creating fairy chess pieces for even more variants in the next update.
