Morning MWG/MCC Forum:

Now, since I have found out 'Pokemon' is programmed in C, I am just waiting for a friend on a forum to reply & help me for some starters. (http://www.cplusplus.com/forum/) In the mean time while I am waiting. I Would just like to know some information on a modification& what it does/whatdoesthisemans/whyisthatfaster? Etc.

Code by SHAD / Click >> Here << for the link

 

print' Throw a grenade ';
$query=mysql_query("SELECT `inv_itemid` FROM `inventory` where `inv_itemid` = $gid && `inv_userid` = $userid");$i=mysql_fetch_array($query); // How is this including the performance? 
if(!$i['inv_itemid'] == $gid) // What does (!$i) mean?{print "Invalid Item";exit;}
if(!isset($_POST['ID'])) {print "User id: 
";
} else {
$_POST['ID'] = abs(floatval($_POST['ID'])); // Does (abs) mean absent?  :P 
$maxMembs = $db->fetch_row($db->query("SELECT COUNT(`userid`) AS `u` FROM `users`")); if($_POST['ID'] > $maxMembs['u']) // What's the (['u']) for?{echo "Invalid user!";$h->endpage();}$ht = mt_rand($mintime,$maxtime);mysql_query("UPDATE `users` SET `hp` = 1, `will` = 0, `hospital` = {$hosptime}, `hospreason` = 'Bombed by {$ir['username']}' WHERE `userid` = {$_POST['ID']}"); event_add($_POST['ID'],"{$ir['username']} [{$ir['userid']}] threw a grenade at you, causing some severe effects. ",$c); // What's ($c) mean? Config?
item_remove($userid, $gid, 1);print" You have successfully threw your grenade .";}$h->endpage();?>

 

Sorry about the code. I Sorted it out 4 times, but It won't code up neatly. :S

$i = mysql_fetch_array($query)

returns as an array,

http://www.php.net/array

abs() = absolute

http://www.php.net/abs

$c = the connection identifier

If I missed anything sorry I don't function well at 2:30am :O

Cheers, Djkanna. You missed something out, but not everyone is a coffee chonga. :D

And I'm surprised you didn't give me links to Wikipedia. Lol

[Djkanna]

:D sorry I just gave the code a quick scan :O

Um.. Wikipedia is usefull but PHP's manual is more usefull when it comes to PHP :O
