a timer as in timer like?

PHP код:

task twosecondtimer[2000]()
{
    //all your functions here.
} 


That's unethical in a way because you could just trigger a function on OnPlayerDeath that checks the achievements.
just like what X337 said

{
       CheckPlayerKills(killerid); //but you'll still need codes inside this to make it work. No way around it
       return 1;
} 


simplifying it would need to use switch-case
