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

[darkely]

I've been reading about him in threads, or YouTube so I finally decided to play the game for myself. To be completely honest it was not very scary at all. However I was wondering how the Slenderman finds the player... like how does the game determine where to place him and such?

From what I've observed he acts like this...

L1 ~ [Game] Note(s) Collected: [if 0 than revert to line 1]
L2 ~ [Game] Note(s) Collected: [if 1 or or more continue to line 3]
L3 ~ [Game / Slenderman] Appear randomly (in front of player but not directly)
