Colouring In Drag and Drop Mobile Journey Game Tutorial

We needed to considerably change yesterday’s Colouring In Drag and Drop Pseudo Element Content Tutorial “Journey Game” logic to work with mobile platforms, to do with …

  • for “easy” Journey Game options we change size of “mytable” table and hide any bottom 💣 bomb emoji display …

    var mapcontext=null;

    function canvasize() {

    //document.getElementById('xmwr').innerHTML+='<sty' + 'le> tr { height: 1vh; } </sty' + 'le>';
    if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) {
    document.getElementById('xmwr').innerHTML+='<sty' + 'le> td { overflow: hidden !important; } </sty' + 'le>';
    }

    var tryimg=document.createElement('img');
    tryimg.onload=function(e){
    var trrectis=null;
    var divvs=document.getElementById('mytable');
    newcanvas=document.getElementById('mymobilecanvas');

    //newcanvas.height=Math.round(tryimg.height * eval(('' + divvs.style.width).replace('px','')) / tryimg.width);
    newcanvas.width=eval(('' + divvs.style.width).replace('px',''));
    newcanvas.height=eval(0.5 * eval(('' + divvs.style.width).replace('px','')));

    mapcontext=newcanvas.getContext('2d');
    mapcontext.drawImage(tryimg, 0, 0, tryimg.width, tryimg.height, 0, 0, newcanvas.width, newcanvas.height);

    document.getElementById('mytbody').style.height='' + eval(0.5 * newcanvas.width) + 'px';
    document.getElementById('mytable').style.height='' + eval(0.5 * newcanvas.width) + 'px';

    //newcanvas.style.display='block';
    var divvsr=document.getElementById('mytable').getBoundingClientRect();
    var trls=document.getElementsByTagName('tr');
    for (var itrls=0; itrls<trls.length; itrls++) {
    if (('' + trls[itrls].id + ' ').substring(0,2) == 'tr') {
    trrectis=trls[itrls].getBoundingClientRect();
    if (('' + trls[itrls].id) != ('tr' + (across == 3 ? 99 : across)) && eval(eval('' + trrectis.top) - eval('' + divvsr.top)) > eval('' + eval(0.5 * newcanvas.width))) {
    trls[itrls].style.display='none';
    //alert('here ' + trls[itrls].id);
    } //else {
    //document.title='' + eval('' + trrectis.top) + ' - ' + eval('' + divvsr.top) + ' <= ' + eval('' + eval(0.5 * newcanvas.width));

    }
    }
    };

  • mobile tr (ie. table row) element heights were not constrained … but now are via directing mobile emoji content to cell itself …

Colouring In Drag and Drop Hazardous Journey Game Tutorial

Back to thinking about Drag and Drop, a lot of the way it works, favours web application game development. You don’t even have to involve the “drop” part of the concept. Just using the “drag” part, and the “ondragover” event, in particular, can be interesting, as we hope you’ve picked up from the work of our current focus, our Colouring In web application.

Long way from just “Colouring In” by now. In actuality it could be “The Drag Show”, but we all know we don’t have the “realia pizzazz” for that title?!

Today, another Reveal option has been added onto the progress of yesterday’s Colouring In Drag and Drop Browse Button CSS Tutorial, which you could call …


Hazardous Journey Game

It involves …

  • map of the world background image … like the other Reveal quizzes and games … and …
  • hidden (like in the minesweeper game) table cells that stop the user in their tracks should they land on them … and …
  • the user can try to start at one World Map edge and try to get to another (over a long enough distance) … following …
  • colour coded Colouring In of table cells (the redder the more imminently dangerous) … as well as …
  • a “hint” system in the “easy” category of play showing these dangerous cells (being as, nobody here is saying anything about this game being easy … but Life Wasn’t Meant to be Easy)

In the PHP parent we capitalize the IDs of dangerous cells …

<?php

for ($thisrow=1; $thisrow<=$across; $thisrow++) {
$cthisrow='0000000000' . $thisrow;
//$rowsofar='<tr id=svgtr' . $thisrow . ' onclick=textbthis(event); style="width:100%;" id=tr' . substr($cthisrow, -$iacross, $iacross) . '></tr>';
$rowsofar='<tr id=tr' . ltrim(substr($cthisrow, -$iacross, $iacross),'0') . ' onclick=textbthis(event); style="width:100%;"></tr>';
//$rowsofar='<tr id=svgtr' . $thisrow . ' style="width:100%;"></tr>';
$ynftone='youllneverfindthis';
$ynfttwo='youllneverfindthis';
$yynftone='youllneverfindthis';
$yynfttwo='youllneverfindthis';
$thistdid='td' . substr($cthisrow, -$iacross, $iacross) . '_';
for ($thiscol=1; $thiscol<=$across; $thiscol++) {
$ynftone='youllneverfindthis';
$ynfttwo='youllneverfindthis';
$yynftone='youllneverfindthis';
$yynfttwo='youllneverfindthis';
$ibv=rand(0, $across);
if ($ibv < ($across / 11) && (isset($_GET['journey']) || isset($_POST['journey']))) {
$ynftone='td';
$ynfttwo='TD';
$yynftone='one';
$yynfttwo='two';
}
$cthiscol='0000000000' . $thiscol;
$thistdidsuffix='' . substr($cthiscol, -$iacross, $iacross) . '';
$rowsofar=str_replace('></tr>', '><td class="td' . str_replace($yynftone, $yynfttwo, 'one') . '" id=' . str_replace($ynftone, $ynfttwo, $thistdid) . $thistdidsuffix . ' style=text-align:center; data-answer=' . $ttcnt . '></td></tr>', $rowsofar);
}
$newih=str_replace('</tbody>', $rowsofar . '</tbody>', $newih);
}

?>

… and this is used in some new HTML and Javascript basis functionality …

Colouring In Drag and Drop Browse Button CSS Tutorial

Some HTML features that interface to the underlying operating system, you may have noticed yourself, are more restricted regarding how you can style them, than the usual HTML element catalogue. One which is always coming up, in this regard, for us is …


input type=file browsing (from underlying operating system files) button

The thing is, as an improvement on yesterday’s Colouring In Drag and Drop Mobile Postcard Tutorial we’re butting up against this issue, because we wanted to make it more obvious for our mobile platform users of our Colouring In web application, that the way in to the functionality whereby they can create and share personalized (online) postcards is via them clicking that input type=file browsing button. And so we went looking for advice and came across this excellent link’s advice that got us to set up the scenario …

Colouring In Drag and Drop Mobile Postcard Tutorial

Yesterday’s Colouring In Drag and Drop Postcard Tutorial mentioned two issues with its Postcard creation functionalities that needed further attention …

We have more work to do regarding data limits (even with hashtagging) using mobile platforms and the Take Photo idea, and we have some text positioning to fix also …

… and today we look into that a bit more.

Regarding “We have more work to do regarding data limits (even with hashtagging) using mobile platforms” we were finding the “Take Photo” iOS Camera app functionality was producing images of more than 3000×4000 and as such, though amazingly it can still work in non-mobile, we were not surprised it didn’t work when shaping to create the mainly hashtagged email link required to share a Postcard with an emailee (ie. email recipient). So we did some pruning …

And regarding “we have some text positioning to fix”, our hunch about the offset needed to fix being the (opposite of the) amount to the top of the imagery in a normal Colouring In webpage, panned out …
