Chess and Draughts Game Styling Tutorial

Onto yesterday’s Draughts Game Logic Tutorial we progress with …

mild styling makeovers for the Chess and Draughts Game look_s …
structure of webpage, in a user experience sense, helping make enough room for the main point of the webpage, the game table board

Primarily, we’d been a bit annoyed by the table rows not having the same height, as the game webpage is first presented. Oddly, this CSS styling Javascript logic helped …

//var rectis=document.getElementsByTagName('td')[0].getBoundingClientRect(); var rectis=document.getElementById('td11').getBoundingClientRect(); var perch=eval(100 * eval('' + screen.height) / eval(eval('' + rectis.height) * 8)); //document.getElementById('mytable').style.height='' + perch + '%'; //document.getElementById('dstyle').innerHTML='<style> #mytable { height: ' + perch + '%; } td { min-height: 12.5%; } </style>'; //alert('' + rectis.height + ' ' + eval(eval('' + rectis.height) * 8)); //document.getElementById('dstyle').innerHTML='<style> html, body , .outer, .inner { height:100%; width:100%; margin:0; } #target { display:block; height: ' + eval(eval('' + rectis.height) * 8) + 'px !important; min-height:100%; } #mytable { display:block; height: ' + eval(eval('' + rectis.height) * 8) + 'px !important; } tr { height: ' + rectis.height + 'px !important; } </style>'; var tbit=' '; if (document.URL.indexOf(deq('draughts')) != -1 || 1 == 1) { tbit=' margin-top: -34px !important; '; } document.getElementById('dstyle').innerHTML='<style> h1 { margin-top: -12px; overflow-x: hidden; text-overflow-x: ellipsis; } #pstatus { vertical-align: bottom; overflow-x: hidden; text-overflow-x: ellipsis; font-size: 12px; white-space: nowrap; } body { background-image: linear-gradient(#f0f0f0, #f2f2f2, #f4f4f4, #f6f6f6, #f8f8f8, #fafafa) !important; } #target { ' + tbit + ' border-right: 1px solid transparent !important; background-color: white; } #mytable { border-right: 1px solid transparent !important; } tr { height: ' + eval(4 + eval('' + rectis.height)) + 'px !important; } td { border: 2px dashed green; } #pwhite { background-color: white !important; } #pblack { background-color: white !important; } </style>';

You’ll also see above a fair bit of negative margin-top styling, in attempts to give precedence to the game parts of the webpage. As well, there is a bit more colour and table cell border pizazz.

Trying not to have the status element be a nuisance we got great help from this great webpage, thanks, for the heads up_s styling to try to avoid line breaks.

Still on the theme for allowing for reduced “above game table board” usage we start using a reveal favourite of ours, to use the details/summary HTML element combination, allowing a user finished with player name settings, forgo seeing the names in order to allow the playing board more height to work with.

And what’s with the Javascript deq wrapper function oddity? Well, just in case a player name involves the letters of draughts (hello “Johnny draughts Gameplayer III”) we fleshed out …

function deq(inideais) { if (document.URL.indexOf(inideais + '=') != -1) { return inideais + '='; } else if (document.URL.indexOf('=' + inideais) != -1) { return '=' + inideais; } return "you'l" + "lnever#findth" + "is"; }

You know what? We’ll leave that topic for another day. But, on a personal level, we like it. We like the concept of reuse, and maybe sometimes we go too far, but in our defence …

a Draughts Game (as proposed today) … has more in common with …
a Chess Game … in the sense that the …
playing board is the same … and, for us, looking for what makes us the same, rather than different, we see …
the Chess Bishop is a lot like a Draughts Default Piece … and …
the Chess Queen is a lot like a Draughts King (which a Default Piece turns into on getting to the other side)

… and far outweigh the differences, in our opinion.

And so, as a principle for us, to facilitate Draughts Game logic, we use Chess Game logic but check for “draughts”, as a word, in this first draft, appearing in URLs as the means by which …

… as we reach Bishop move validity checks (in a Chess Game) we intervene with our Draughts Game new intervening logic …

… as the first worry we attended to. But there’s also …

emoji changes … alas, the “more apt” …
Black draughts king is ⛃ ⛃ (vs ⛂ ⛂) white is ⛁ ⛁ (vs ⛀ ⛀)
… emoji set did not look good, yet, for us, and so we took our Bishop and Queen piece similarity ideas to heart, so that the player is not confused (but into other drafts, we may do better)
and the “only black square” positioning (we’d forgotten about Draughts, since playing it as a kid)
the rule “you have to take opposition pieces, when possible”, which we are not enforcing on this “first draft”
the “multiple hop” moves in Draughts we’ve given the user 10 seconds to show they intend to pursue, which do not happen in Chess (unless you categorize Castling as being like that) has, so far, hampered our email or SMS methodology means by which the opponent’s last move is shown coming off the email or SMS link’s web browser address bar URL navigation (as we can do for Chess games)

… matters to attend to.

Why are we needing this? Well, after the layout posting, populating a traditional Chess board with the default chess player positions, we lost the Drag and Drop “smarts” for the tabular span elements.

We asked ourselves …

How best to fix the problem for mobile platforms and minimize the interference to existant non-mobile platform working code?

And we thought …

We could introduce a whole new separate layer of event logic with an event that does not occur in the non-mobile realm … ontouchdown

Chess Game Practice Castling Tutorial

Maybe in mathematics, in school, you discussed limits (and/or perhaps even “proof by contradiction” and/or “paradoxes”). You know, those fancy ways of saying if “such and such” you never finish the race, such as in “Achilles and the Tortoise” …

Achilles and the tortoise

Achilles and the tortoise
In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.

— as recounted by Aristotle, Physics VI:9, 239b15
In the paradox of Achilles and the tortoise, Achilles is in a footrace with the tortoise. Achilles allows the tortoise a head start of 100 meters, for example. Suppose that each racer starts running at some constant speed, one faster than the other. After some finite time, Achilles will have run 100 meters, bringing him to the tortoise’s starting point. During this time, the tortoise has run a much shorter distance, say 2 meters. It will then take Achilles some further time to run that distance, by which time the tortoise will have advanced farther; and then more time still to reach this third point, while the tortoise moves ahead. Thus, whenever Achilles arrives somewhere the tortoise has been, he still has some distance to go before he can even reach the tortoise. As Aristotle noted, this argument is similar to the Dichotomy.[14] It lacks, however, the apparent conclusion of motionlessness.

Beware the project that runs the same way, by worrying too much about the one percent_ers. On the other side of the ledger though, is that you learn far less when not trying to tackle any of those one percent_ers. With these thoughts swirling around we undertook the first of the “doozies” (amidst a lot of swearing and “what have we gotten ourselves into here” thoughts) referenced in yesterday’s Chess Game Practice Basic Moves Tutorial …

Castling (between a Rook and a King with a lot of provisos)

We learnt things about the interface between “drag events” and events like “onmouseover”, the latter of which we needed to resort to, alas. If you didn’t, life would be much easier, and try to design the initial premise, perhaps, better, so that those two wooooorrrrlllldddsss never have to meet (and just image the in-law get togethers!).

We learnt, again, that DOM methodology can come undone when there is no time gap between element arrangements that rely on a previous Javascript DOM arranged task. Take a look at our setInterval Javascript function setup to help here …

… called into play via “one only” call …

setInterval(dodoms, 1000);

… and given DOM (but doesn’t have to be) jobs to do via Javascript commands, such as a few examples from our “Castling” code …

domcmds.push("document.getElementById('td202').innerHTML='" + wsixoh + "'; "); domcmds.push("document.getElementById('td203').innerHTML='" + spanfive + "'; "); domcmds.push("document.getElementById('tr8').innerHTML='" + wwtdtte + "' + document.getElementById('tr8').innerHTML; itisthiscmove='b'; adddrop('" + lohoh.split(' id="')[1].split('"')[0] + "'); ");

… the Javascript DOM actions of which would have a one second gap between each domcmds[] array member “call to action”.

A little esoteric, we know, but research (thanks to this useful link) got us to (finally) discover the Clayton’s emoji.

It’s (the “nobreak”) …

Why, regarding chess, are we interested? It means regarding the two black rooks, for example, adding a ⁠ to its display contents makes little difference, but we can hone in on an exact black rook, “innerHTML” wise, in the code.

You learn most from your mistakes

… just as we’re curious about “the things that go wrong”, and not having them repeat! Same with pooches!

Take our firstto seconddraft PHP game (to the opera, would be preferable). We wondered why, occasionally, with the “first draft” it would hang. It took us a half day to realize, as you could yourself have tweaked to a lot quicker if you had followed the adage …

Hanging issues mostly team up with code within a loop

The situation, we’ve reasoned, is that we had that PHP $badlist variable store a comma separated list of planets with either zero moons or more than one moon randomly selected representing it. We’d assumed, yesterday, not that we’d put it in words, but in logic, that this list would not (have the same length or) be the same as a (new $goodlist variable) list of planets with either zero moons or selected while collecting the random list of Moon/Planet combinations … ie. we assumed in the list would be a Planet with only one of its Moons randomly selected … mistake!!! Better is …

Can “inheritance” be harnessed to make it work for some complexity of nested HTML elements inside that “Drop Zone” element when the document.body’s onload event happens?

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

… but our testing of the methodologies on various platforms hasn’t totally failed yet on any of the several desktop and mobile platform scenarios we’ve tried. On mobile, we just held on for a sustained touch (down) to make it possible. So maybe the industry has caught up with the ideas? We’re hoping so, because “drag and drop” is a kind of natural thing online users think of to do, and people associate it with “getting things done” we reckon.

Anyway, we relied on the great source code of the second of two inspirational webpages DataTransfer: setData() method, thanks …

The DataTransfer.setData() method sets the drag operation’s drag data to the specified data and type. If data for the given type does not exist, it is added at the end of the drag data store, such that the last item in the types list will be the new type. If data for the given type already exists, the existing data is replaced in the same position. That is, the order of the types list is not changed when replacing data of the same type.
