Dots and Boxes Game Parameterization Tutorial

Dots and Boxes Game Parameterization Tutorial

We quite like …

• substitutional approaches to coding
• interpretive approaches to coding
• take a hardcoded string and either …
  1. parameterize it
  2. repurpose it

… and with the “Dots and Boxes Game” web application of yesterday’s Dots and Boxes Game Primer Tutorial it’s a case of parameterizing the table …

• number of “span” cells across (used to be 100)
• number of “span” cells down (used to be 20)

… as per the device width dependant …


var xacross=Math.min(100,Math.round(eval('' + screen.width) / 14.40)); //100;
var ydown=Math.round(eval(xacross / 5)); //20;


… teamed with changes to 100 and 20 and “near to” Javascript code hardcodings changed into forms of “xacross” and “ydown” variables above.

And then there is the hardcoding “Score” we wanted to repurpose so as to allow the user control of whether …

• notifications
• “say” audio
• “toast” message box

… are persisted with, via “toggling code” as per …


var snotifications_on=true;
var osay_on=((('' + navigator.platform.toUpperCase()).indexOf('MAC') >= 0) ? true : false);
var etoast_on=(navigator.userAgent.match(/Android|BlackBerry|iPhone|iPod|Opera Mini|IEMobile/i) ? true : false);

function pse(insc, istoast) { // insc is "Score "
var outsc=insc;
if (outsc.indexOf('Score') == 0) {
outsc=outsc.replace('e', '<a title="Toggle toast show status ' + ('' + etoast_on) + '" onclick="etoast_on=!etoast_on; this.title+=String.fromCharCode(32) + etoast_on;" style="cursor:pointer;text-decoration:none;color:' + (istoast ? 'magenta' : 'magenta') + ';">e</a>');

Dots and Boxes Game Primer Tutorial

Today, do you fancy …

… onto yesterday’s SOS Game Primer Tutorial with our new “Dots and Boxes” game?

Yes, that’s it for us today, simply because the “morphed into” is a lot like “the end result”, our new Dots and Boxes Game. After all, both are …

• online games
• on a board
• with span cells
• containing onclick logic
• ideally for 2 or more players

And as for the onclick logic Javascript logic? We can’t remember relying on the outerHTML (ie. the entire HTML element expressed as HTML) of an HTML (span) element for the (onclick event) logic basis, as per (the plug in code different to (and the same as) yesterday’s code) …

SOS Game Primer Tutorial

Even though it took too long to get to yesterday’s Word Find Game Viewport Tutorial‘s Word Find Game’s level of satisfaction, for us, it was always going to be worth it, because when you overengineer it can mean cloning off that into another useful web application is a “paring down” exercise, more than anything, and this is infinitely easier than “a reinvention of the wheel” scenario, especially where it comes to “cross platform” game usage “user experience” issues.

The fun bit of such an approach, in thinking about what we end up with today is the thought that a …

• Word Find Game … could be cloned or morphed into a …
• SOS Game

… we remember from our days at high school, in less than a day. The memory of the SOS Game did not extend to the detail, and so we thank How to Play – SOS for reminders about the status of diagonality, while up versus down and forwards versus backwards concerns were a bit “per se” regarding “SOS”!

It was the confluence of one “onclick” type event to cover, regarding span elements set out in a grid initialized to a non-breaking space ( ie.   ) …

• fill in contents as “S”
• fill in contents as “O”

… that set us to determining for the span “cell” click, was it positioned …

• in the top half means “S” … or …
• in the bottom half means “O”

? This had us converging on changes to the “clicks” mode onclick event Javascript logic …

• we start asking for an optional (comma separated) user name list … that if used …
• starts looking for Notifications API functionality to keep the players informed about proceedings … and …
• if underlying Navigator API navigator.platform points at an underlying macOS operating system, also offer the user the chance to turn notification wording to audio commentary, as well

… as per Javascript …

• remembering those word find games you might find in the Sunday newspapers … and as a coding basis …
• textarea and Selection API user interface you can prepare for by reading yesterday’s Selection API and Clipboard API Tutorial

Today we just do the “proof of concept” first draft word_find_game.html, because the Selection API highlighting really suits …

• horizontal forwards
• horizontal backwards

… word finding in the game, but we also want to allow for …

• vertical down
• vertical up
• diagonal right down
• diagonal right up
• diagonal left down
• diagonal left up
