Word Find Game Personalization Tutorial

Yesterday’s Word Find Game Modes of Use Tutorial gave us the means by which we could have multiple players in our “Finding the Word” game, as a number. But many users prefer “names” to “numbers”. And so …

  • 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 …


function notify(what) {
if (what.trim() != '' && anames[0].replace('Player 1','').trim() != '') {
if (what != lastwhat) {
lastwhat=what;
setTimeout(lwn, 8000);
document.getElementById('notif').src='./notifications_ideas.php?scheduledblurb=' + encodeURIComponent(what);
if (trysay) { //alert('HTTP://localhost:8888/macos_say_record.php?andsoonclose=y&docronwork=say%20' + encodeURIComponent(what));
window.open('HTTP://localhost:8888/macos_say_record.php?andsoonclose=y&docronwork=say%20' + encodeURIComponent(what), 'sayif', 'top=50,left=50,width=500,height=500');
}
}
}
return what;
}

Word Find Game Modes of Use Tutorial

Online games often feature …

  • degree of difficulty
  • number of player(s)

… modes of use that the user(s) can control. And so, with this in mind, to improve on yesterday’s Word Find Game Underlay Tutorial we’ve set out providing ways the users can control these two concepts via two new dropdowns …


<h1>Word Find Game <select onchange="restart(this);"><option value="hard">Hard</option><option value="easy">Easy</option><option value="easier">Easier</option><option value="easiest">Easiest</option></select> <span id=curbit>for</span> <select id=numsel onchange='nparrange(this);'><option value=1>1 player</option><option value=2>2 players</option><option value=3>3 players</option><option value=4>4 players</option><option value=5>5 players</option></select></h1>

… along with a span element showing the current player number all within that topmost h1 element, and helped out by two new dropdown (ie. select element) onchange event Javascript logics …

Today’s “Word Find Game” gets its inspirations from two sources …

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

… which can be handled, but in a pretty kludgy way …
