Hello I've written a little plugin with a blaze rod and cooldown but the cooldown doesnt work
Here is the file while I dont know where the error is

I can't fix it but here's another way to post your code!

PHP:

$startTime = time();
// More code...
if((time() - $startTime) <= $integer)
{

  // Do stuff...

}
else
{

  // Do stuff...

}


You can use PHP tags, instead of CODE tags.
