Chess Game Practice Layout Tutorial
Onto yesterday’s Chess Game Practice Tutorial‘s Chess Game Practice web application, today, we’ve developed further, in a “layout” sense, to allow for …

- initiate the Chess Board for a traditional game of Chess between black and white players … and …
- weird layout of Chess Board where pieces are placed randomly and nonsensically
… but no piece move logic yet! That is for tomorrow, but this “layout” logic helped us get to a better piece identification set of protocols to work with. So, try the changed experimental_drag_and_drop.htm HTML and Javascript and CSS assisted “second draft” chess_game.php Chess Practice Game for you to … practice (after choosing a layout) …

A little esoteric, we know, but research (thanks to this useful link) got us to (finally) discover the Clayton’s emoji. In other words, an emoji taking no (or little to no) screen display space but differentiates one emoji representation from another when you want to just differentiate via “innerHTML” content, for HTML elements. It’s (the “nobreak”) …
You missed it?! Try …

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.

We wanted to improve functionality, by changing our usual “-” hardcoding to a link “+” idea whereby the user can enter in their own “yourblurb” sentence, as above. It being collected in a Javascript prompt popup window, the user can enter emojis (via control-command-space for macOS or Mac OS X, logo key + . (period) for Windows, control=space for iOS, top left + for Android keyboard) as part of the sentence mix, the only rule being a space character separates words in a sentence with our further changed experimental_drag_and_drop.htm HTML and Javascript and CSS sentence shuffle game web application.

On your smaller devices we found the Numbers Guessing Game a bit hard to use. As such, we researched and played around with “drag and drop” cursor ideas unsuccessfully to end up, instead, not thinking about the cursor (albeit, we find that idea cuter) but rather styling the target table cell’s background colour and informing the user of that up at the top button wording in our changed second draft PHP game, which leans on our changed experimental_drag_and_drop.htm HTML and Javascript and CSS helper…
var lastbco=null;
const target = document.querySelector("#target");
target.addEventListener("dragover", (ev) => {

console.log("dragOver " + ev.target.id + ' ' + ('' + ev.target.style.backgroundColor).replace('white','') + ' ' + document.body.innerHTML.indexOf('tab' + 'lece' + 'llb' + 'c'));

Another thing that there is nine of (as contentious as it is regarding Pluto) is Planets in the Solar System, revolving around the Sun.

Again, PHP uses a framework of Experimental Drag and Drop HTML and Javascript and CSS, mainly via one PHP codeline …

We fully concur with any adage that goes …
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 first to second draft 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 …
<?php
$goodlist=',Mercury,Venus,';
$badlist=',Mercury,Venus,';
while (strlen($goodlist) == strlen($badlist)) {
$goodlist=',Mercury,Venus,';
$badlist=',Mercury,Venus,';
$correctans=rand(0,8);
$sofar=';';

The experimental drag and drop theme continues on today, after Experimental Drag and Drop Game Tutorial‘s debut game application, with a Wikipedia inspired “Australian Street Type” game today.
Huh?! Well, you know those street names that baffle? Or are we easily baffleable?! Anyway, you had to be there. And if you ever feel you’re alone with an interest, just look it up in Wikipedia or Google and you’re almost sure to find out …
you are not alone
Yes, our Wikipedia page mentioned Australian Street Type Designations with their lawyerly Australian Street Type Descriptions. Who could ask for more? Well?!

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. This is how we felt about yesterday’s Experimental Drag and Drop Primer Tutorial and that teamed with the wonder about how we could add some useful complexity to our “Experimental Drag and Drop” web application’s …
Drop Zone
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? We wondered whether a Brady Bunch style 3×3 table could be the go? And whether the nine cells could have a “score” associated with them, and that set of scores be changing over time to make the game more challenging and interesting? Well …
Yes
… is the answer regarding making a game out of a proof of concept with our experimental_drag_and_drop.html HTML and Javascript and CSS game web application (also shown below) using these techniques, about which we think some of you readers will be interested?!

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.
