Chess Game Midway Scenario Layout Tutorial

Chess Game Midway Scenario Layout Tutorial

We are always intrigued by those Chess “end game scenarios” that appear in the newspaper. We’re guessing to get good at Chess you need to know strategies to adopt for various scenarios. With that in mind, in addition, onto those …

• drag from an emoji sentence the Chess pieces … and …
• traditional layout game of Chess … and …
• weird and random layout game of Chess … today we’d like to add …
• scenario descriptor mechanism to recreate a Chess endgame or “midway game” or even “near the start game” set of circumstances (which the user can define)

We just added a Javascript prompt popup window means by which we could add this, adding into the PHP parent code the new button …

The “touchdown” referred to in our blog posting title (further to the work of yesterday’s Chess Game Practice Castling Tutorial) …

• is not a Gridiron score … but …
• the “touch” mobile platform event which is the “touch” equivalent to the “mouse” event onmousedown (preceding the onclick event, in the normal flow of events)

… and … yes … that’s worth a yayyyyyy!!!! in anyone’s language.

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

The Javascript code below can populate the elements of interest with new ontouchdown (discrete clicking or touching) logic for the chess piece moves.

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 …


var domcmds=[];


function dodoms() {
var stopit=false;

stopit=true;
//if (prompt(domcmds[ikj], domcmds[ikj])) {
eval(domcmds[ikj]);
//}
domcmds[ikj]='';
}
}
//domcmds=[];
}


… 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 + "'; ");

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 …

It can be interesting turning a “concept” (or even a “proof of concept” web application) into an, on the side, “game” web application, and that way, learn what’s possible via user action.

Experimental Drag and Drop Primer Tutorial

We’ve added the word experimental into today’s blog posting title, mainly because our first of two inspirational webpage sources (last modified on 23/02/2023) regarding somewhat alternative “Drag and Drop” functionalities told us, regarding the DataTransfer object informational “DataTransfer” webpage …

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.
