PHP Code:
if( victim == killer )
{
return PLUGIN_CONTINUE
}
if(victim)
PDEADS[victim]++
if(killer)
PFRAGS[killer]++
check_level(killer)
where it is ++ you need to make another way to add +2 or +3 .... and not ++ because ++ equal (+1) about the headshot you need to use that function get_user_wstats to check Which part of the body The Killer Hit .... and then make a function like ... if (the killer hits head){get +5}else return... All of this it is just for example purposes ...
