Hey aLL!!
So... (f*ck i always start a post with So... -.-)
Im still making my browser game
(yayyy) and i got the construction system working properly (double yayyy)!
And now.. i face the biggest problem of my life... nahh just kidding.. well im kinda trying to make a system or something that allows me to display how much time left to build the building. like: HOUR:MINUTES:SECONDS or just MINUTES:SECONDS.
My time system its that one
i store the seconds that passed from 1970 i think till now plus the build time and then keep checking how much is left to the actual time(); become bigger than the other.
And till now i got a display in seconds
Any ideas?

Well i'll tell you the way I do it..
I store the time it will finish the building in teh db
column: time_to_finish
type: datetime
then if the player gets on the page at any time before the building finishes.
Code: Select all
$query=mysql_query("SELECT `time_to_finish` FROM `table` WHERE `building`='$building_id'") or die();
$result=mysql_fetch_assoc($query);
$sec_to_finish=strtotime($result['time_to_finish']) - time(); // time_to_finish is in the future so it's greater than current time.
if($sec_to_finish <= 0){
// the building has finished
}
else{
// echo the *countdown
}
I have a countdown at
this post which you can display the H:M:S left until the building finishes.

Found this:
http://pure-essence.net/2005/05/05/time ... -function/
Code: Select all
$currentTime = time();
$futureTime = time() + 12348234;
$difference = timeleft( $currentTime, $futureTime );
foreach( $difference as $key => $amount )
{
echo ( $key > 0 ? ':' : '' ) . $amount;
}

Code: Select all
$currenttime = time();
$futuretime = $tempoc;
$difference = timeleft($currenttime, $futuretime);
echo "<center>" . $lang['Construindo'][$language] . " ";
foreach($difference as $key => $amount)
{
echo ($key > 0 ? ':' : '') . $amount;
}
echo "</h4>";
its working properly
just want to refresh the time every second (just the time
)

You'll need JavaScript to do this.
My suggestion would be to calculate the time change in JavaScript aswell.
Try this:
Code: Select all
<span id="timer">
</span>
<script type="text/javascript">
var currentTime = <?php echo time(); ?>,
futureTime = <?php echo $tempoc; ?>,
timerSpan = document.getElementById('timer');
function timeLeft(current, end)
{
var days = 0,
hours = 0,
minutes = 0,
seconds = 0,
left = end - current;
if( left > 0 )
{
days = Math.floor(left / 86400);
left -= days*86400;
hours = Math.floor(left / 3600);
left -= hours*3600;
minutes = Math.floor(left/60);
seconds = left - minutes * 60;
}
return days + ':' + hours + ':' + minutes + ':' + seconds;
}
setInterval( function()
{
currentTime++;
timerSpan.innerHTML = timeLeft(currentTime, futureTime);
}, 1000 ); // loop every second
</script>

The script shows the time left inside the element with the id "timer", in my previous example I used a span tag. I noticed you are closing a h4 in your code so my guess is you want to achieve this (note this isn't the ideal means of achieving this):
Code: Select all
echo '<h4 style="text-align: center">' . $lang['Construindo'][$language] . "</h4>";
echo '<h4 id="timer"></h4>';
?>
<script type="text/javascript">
var currentTime = <?php echo time(); ?>,
futureTime = <?php echo $tempoc; ?>,
timer = document.getElementById('timer');
function timeLeft(current, end)
{
var days = 0,
hours = 0,
minutes = 0,
seconds = 0,
left = end - current;
if( left > 0 )
{
days = Math.floor(left / 86400);
left -= days*86400;
hours = Math.floor(left / 3600);
left -= hours*3600;
minutes = Math.floor(left/60);
seconds = left - minutes * 60;
}
return days + ':' + hours + ':' + minutes + ':' + seconds;
}
setInterval( function()
{
currentTime++;
timer.innerHTML = timeLeft(currentTime, futureTime);
}, 1000 ); // loop every second
</script>
<?php
// continue php script
