Colouring In Drag and Drop World Reveal Sharing Tutorial

Colouring In Drag and Drop World Reveal Sharing Tutorial

When a lot of us think of games or quizzes, we think “level playing field”, at least at the start of a game. In other words, the way the game starts the players are faced with the same or similar conditions to play the game under. And so, onto the logic for the World Reveal game subsection of functionality of our Colouring In web application, as of yesterday’s Colouring In Drag and Drop World Reveal Geography Tutorial, today, we’ve added in logic so that …

• a World Reveal incarnation of the Colouring In web application can be shared via …
  1. email
  2. SMS

  … and …

• the first ten (as a default, and can be changed via a ?qnum=55 style of argument or #qnum=67 style of hashtag) questions are the same for the originator as the recipient

Encryption wise the simplest to share is alpha data and here it is with this. Country ISO-2 character code sharing needs no delimitation, just for us, looping through two characters (also used, along with function orflag below to make the draggable element into a Country flag emoji) at a time!

• it has intelligence regarding a “pen” type emoji element being dragged over a table full of cells
• it can handle background images
• it can involve text
• it can colour table cell background colours (and/or border part(s))

… and this is functionality allowing us to add a new “pen” drag type called “World Reveal” where a semi-transparent Mercator projection World Map image is underlayed beneath semi-transparent table cells, creating a “cloudy world effect”. The user is asked to reveal a country of choice to score in the game, those table cells dragged over becoming fully transparent, showing “uncloudy world” beneath …

If you think in terms of …


Annotation functionalities


… available to the user of our current interest, the Colouring In web application, up until today, we relied on user scribbling means to involve any “textual feeling” in this project.

But, today?! Well! That’s another kettle of fish! We’re happy to say …

We’re involving real text into the mix.

… regarding the ways you creatives out there want to express themselves.

And so, onto yesterday’s Colouring In Drag and Drop Animated Background Images Tutorial we have some new involvement of …

• tr (table row) elements given a new id attribute arrangement and some new event onclick logic … and also …
• tbody (table body) element used as the creator’s palette (as far as positioning goes, though, as we go to air, we’re still using the tbody for co-ordinate positioning (and we wanted svg+xml text background imagery at first) but now overlay span element text over the table)

Sad about the full involvement of tbody svg+xml background image text idea not happening, but we feel that we will return to this, on paper, satisfying, and cute, idea. We have successfully applied svg+xml text ideas to tailored cursors, but we do remember a struggle and size limitations?! The attempt is there in the code for another person to do better with, if they wish.

Colouring In Drag and Drop Multiple Background Image Tutorial

The ability to add multiple background images in HTML and using CSS can be very useful. We’ve done this in the past, and knew the important CSS properties to fill in were …

• background-image
• background-repeat
• background-size
• background-position

… which should be given comma separated list values for each background-image set member.

Below, we drill down a bit …

• background-image … comma separated list of data-URIs and/or image URLs (and perhaps, optionally, the one linear gradient prefixing opacity measure)
• background-repeat … easy … no-repeat comma separated list
• background-size … if one you might use contain but from there on, today we use a width percentage value and auto for the height component (eg. 33% auto)
• background-position … top left, bottom right, top right, bottom left, center center, top center, bottom center, left center, right center … in rotation (and order is today’s thinking) … beyond 9 there will be overlaying (and maybe even before then, depending)

Despite us having precedents to turn to regarding …


establishing a layer of keyboard onkeydown event logic for a non-textbox HTML element


… we’ve had to look up so many websites for advice, thanks, that it must have been that “day of discovery” you should persevere with, for reference points into the future.

Alas, little of it can be used on mobile platforms. Their setup precludes these keyboard independency possibilities we really like about non-mobile keyboard event functionality. It can set up a “whole new woooorrrrllllddd” for your web application designs!

What was the motivation for our interest? Well, we have a mouse with a mouse wheel, and it occurred to us how useful the wheel could be when dragging and some content is below the fold, and rather than lose the dragging, you can use the mouse wheel to navigate to those areas of the webpage, still dragging your draggable element, with our Colouring In web application.

And so, onto yesterday’s Colouring In Drag and Drop Mixed Platform Collaboration Tutorial …

var defemail='';
var defsms='', snum=null, sparewes=null;
var prefixnickchar='.';
var prefixfor='<td class="tdone" id="';
var suffixnickchar='-';
var suffixfor='" class="tdone" style="text-align:center;" data-answer="1"></td>';


… and for those untouched cells you’re saving more than (because of encryption) the length difference between the “nickchars” above and their “fixfor” counterparts for each “boring” table cell encountered. And all this eases our mind somewhat, as a design, realized, on the way to the emailee or smsee this way …

Colouring In Drag and Drop Settings Tutorial

Onto the start for our Colouring In web application via yesterday’s Colouring In Canvas Clone of Numbers Guessing Game Tutorial we’re starting to enhance, on top of that “clone level” functionality, via two new settings with two approaches to the management of data, regarding, those being …

• number of table cells across (that programmatically is made to be the same number of cells, as down) … we deal with via a get ? (or &) address line URL arrangement … whereas …
• pen “width” can be 1 or 2 (where 2 colours in the 1+8=9 surrounding cells of a dragged over cell) … we deal with via a hashtag arrangement

Why the difference in approach? Let’s start with hashtag methodologies. This arrangement can leave everything about a webpage, in place, regarding the user actions on a webpage, while the Javascript can detect that change in …


location.hash


… dynamically. In other words some dragging canvas drawings with pen “width” 2 can be combined with some using pen “width” 1 in the same user creation.

But when the data management involves get ? (or &) address line URL arrangements, this involves navigation to a new incarnation of the webpage creation logic, effectively wiping the webpage slate clean. This is apt for the “number of table cells across” data item, because the HTML content of the table element is not just affected, but is totally structured, according to this user setting.

Lately, more and more, we’ve been hashtagging data to dynamically created “a” link “mailto:” email or “sms:” SMS communication body webpage URL links. An email link or SMS link, from the recipient’s point of view is a “brand new start” that can address either or both of these data conduit arrangements, we’re getting happier and happier to discover …

Today we’re honing in on …

• drag and drop methodology …
• dragover event … value adding where …
• drop element(s) are cells of an HTML table element (also a drop element)

… as our interest. We scouted around for the best “design match” and came up with the arrangements existing when we presented Numbers Guessing Game Tutorial some time ago now.

And if we succeed with some form of value adding here, we have another idea for the ideas we’re presenting today. Spoiler alert! Yes, it can be made to be useful.

As such we’ve …

Added toggleable “show where contemplated” value added border where dragover logic
<?php $templategame=file_get_contents('./experimental_drag_and_drop.htm'); if (isset($_GET['notice'])) { $templategame=str_replace('>-</span>', '><a style="text-decoration:none;cursor:pointer;" title="Stop showing where contemplated as well." onclick="location.href=' .

Tweaked dragover logic
target.addEventListener("dragover", (ev) => { if (lastbco) { lastbco.style.backgroundColor='white'; lastbco=null; } if (ev.target.outerHTML.indexOf('<table') != 0 && ev.target.outerHTML.indexOf(' data-piece="') != -1) { if (ev.target.outerHTML.split(' data-piece="')[1].substring(0,1) == (itisthiscmove + ev.target.outerHTML.split(' data-piece="')[1].substring(0,1)).substring(0,1)) { lohfulloh=ev.target.outerHTML; console.log("LOHfulloh=" + lohfulloh); } } //console.log("dragOver " + ev.target.id + ' ' + ('' + ev.target.style.backgroundColor).replace('white','') + ' ' + document.body.innerHTML.indexOf('tab' + 'lece' + 'llb' + 'c')); //if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) { // document.title='ev.preventDefault(); //4'; //} ev.preventDefault(); if (('' + ev.target.id).indexOf('td') == 0 && ('' + ev.target.style.backgroundColor).trim().replace('white','') == '' && document.body.innerHTML.indexOf('Numbe' + 'rs Guessi' + 'ng Ga' + 'me') != -1) { //document.getElementById(sourceid).style.opacity='0.6'; lastbco=ev.target; ev.target.style.backgroundColor='pink'; if (document.getElementById('mybut')) { if (document.getElementById('mybut').innerHTML.indexOf(' ..

Flag any continued “show where contemplated” interest
var secsmore=''; if (('' + document.URL + decodeURIComponent('' + location.hash)).indexOf('notice=') != -1 && ('' + decodeURIComponent('' + location.hash)).indexOf('no_tice=') == -1) { secsmore='¬ice=y'; } if (document.URL.indexOf('rjmprogramming-com-au.translate.goog') != -1) { location.href=document.URL.split('&score=')[0] + '&score=' + score + '&secs=' + secs + secsmore; } else { location.href=document.getElementById('callback').value + '?score=' + score + '&secs=' + secs + secsmore; }

… to, as the user requests, add some table cell border enhancements (as our “value adding“) to our tweaked third draft PHP game (helped out by the changed experimental_drag_and_drop.htm Experimental Drag and Drop clientside HTML and Javascript basis), as the user drags the draggable element over the table droppable element and its cohort table cell elements.

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 …

Enneagram Type Game Tutorial

A lot of us wonder what goes towards making up our personalities. We remember doing a Myers-Briggs test for some job as part of the vetting process. We thought we’d write another experimental drag and drop game, like yesterday’s Australian Street Type Game Tutorial, regarding …

Enneagram Types

… of human personalities, and we found a webpage linking these categorizations to Hollywood Movie Stars for you to get the gist of the ideas. We also thank Wikipedia as our source for Movie Star images.

It being a topic …

1. beyond our ken
2. outside our usual subject matter

… you may be wondering how we stumbled upon the idea? We let Google autocomplete our …


nine types of


… search textbox typing, fully expecting “Carol”_? to be at the top of the list when we saw …


nine types of enneagram


… to flesh out a family of “game interest”, we hope?!

Our first draft PHP game is also playable below …

Australian Street Type Game Tutorial

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?!

To make this happen we wrote some PHP, which leans on a changed experimental_drag_and_drop.html HTML and Javascript and CSS game web application basis, or template, to mould and bend towards our purpose … nga ha ha!

Our first draft PHP game is also playable below …

Experimental Drag and Drop Game Tutorial

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?!

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.

… to get us going with our “proof of concept” web application (also shown below) using these techniques, about which we think some of you readers will be interested?!
