How does the Slenderman's AI (if that) work?

[JeadDovah]

I've Played it for a few times but i've seen many vids abot and i think i know how it works

-the slenderman spawn in X-distance from you by starting the game
- slender man has a specal range in that he can spawn For example: he can once in X seconds spawn
X meters
- the Range and/or the spawnrate grow with any page you pick up
- light (flaschlight) generates a Kind of shaddow how the slenderman can see
- he follows you
-if youre Standing still he overtake you and
- he recording specal ticks of you ( For exemple: if you loocking often for him he teleports in your back)

(sorry for my bad englisch)
