Meet Freddy and the Gang

Understand the AI levels and movement patterns of Freddy, Bonnie, Chica, and Foxy in Five Nights at Freddy's: Sister Location. Learn how their AI affects their behavior each night.

In the world of Freddy Fazbear's Pizza, you'll face four primary adversaries: Bonnie the Bunny, Chica the Chicken, Foxy the Pirate Fox, and Freddy Fazbear himself. While each has unique personalities and attack methods, they share a core logic for movement around the restaurant.

On the Subject of AI Levels and Animatronic Movement

Completing Night 6 unlocks a Custom Night where you can set each antagonist's AI level from 0 to 20, with higher values increasing difficulty. These levels directly influence enemy movement.

Each enemy has a specific time interval for a "movement chance":

• Freddy: Every 3.02 seconds
• Chica: Every 4.98 seconds
• Bonnie: Every 4.97 seconds
• Foxy: Every 5.01 seconds

At these intervals, a random number between 1 and 20 is generated. If this number is equal to or greater than the enemy's AI level, their movement "succeeds." If it's lower, the movement "fails." Each AI level increase equates to a 5% greater probability of movement, from 0% at level 0 to 100% at level 20.

The game uses pre-set AI levels for each night, essentially pre-configuring the Custom Night parameters:

*On Night 4, Freddy's AI level has a 50% chance of being 1 or 2.

While AI level 0 suggests no movement, enemies do move on Night 1 due to AI level increments that ramp up the challenge:

• At 2 AM: Bonnie increases by 1.
• At 3 AM: Bonnie, Chica, and Foxy increase by 1.
• At 4 AM: Bonnie, Chica, and Foxy increase by 1 again.

For example, Night 1 starts at 0-0-0-0, becomes 0-1-0-0 at 2 AM, then 0-2-1-1 at 3 AM, and finally 0-3-2-2 at 4 AM, remaining at these levels for the rest of the night.

This forms the core movement logic for all enemies, with individual AI specifics to be discussed next.
