Freddy: He will slowly move towards you in intervals. Moving away from him is the best course of action.

Bonnie/Chica: They will search for you, don't step in their lights or else you'll most likely die. Bonnie can hear sounds made by the player, Chica can not.

Foxy: Shine your light at the right time or else you will die a horrible death.

Hopefully this helps those who might not understand how to deal with the AIs.
