making a class for a monster

[Neelke]

hey i was wondering how to make a own custom class for a monster, so he has a different behavior then the other monsters from the game cause i want it to be like amnesia where it will find you easy and not have to take like 5 minutes for it to actually chase you and aswell the noises, like when the brute or something has been spawned in

I suggest you look into how classes work then. It's surely possible to do what you ask for, but it's best learning the basics of classes first in your case then.
