Query Question (Energy)


Recommended Posts

How do i make it so it takes away 10% energy from a user, this query just

$db->query("UPDATE users SET energy=maxenergy-10 WHERE userid=$userid");

$db->query("UPDATE users SET energy=maxenergy WHERE energy>maxenergy");

and also how do i make it so it dies if its less then 10% energy

if($ir['energy'] < 1)


die("Sorry, it costs 10 energy to bust someone. You only have {$ir['energy']} energy. Come back later.");

Re: Query Question (Energy)

Maybe somethign like this...


$percent = $ir['maxenergy'] / 10;

//Takes 10% from them
$update = sprintf("UPDATE users SET energy = energy - '%u' WHERE userid = '%u' ",

//This stops energy below "0"
$check = sprintf("UPDATE users SET energy = '%d' WHERE energy < '%d' AND userid = '%u' ",

if($ir['energy'] < $percent)
