Create a new zone type (if none fits your needs) -> create a new zone based on the npc's coordinates on spawn -> add the zone to the manager -> remove the zone from the manager when the npc get killed.
So, quality doesn't matter as long as it works?
I mean requirements like, for example, 1-2-10 years of exp, HTML5, PHP 5.6/7.0/7.1/7.2, Symfony (whatever version), Laravel, Angular 2, etc.
Or such things doesn't matter?
AccessDenied, for 4 months you have 46 posts only... how could you let that happen? You used to be the biggest spammer around as far as I remember... :D
You gonna spend some time, money and effort for nothing. If that is what you want to do, just do it, you gonna fail anyway, even if you do great... my first comment wasn't a joke.
