Fighter AI

**Fighter AI** is an AI type used by a variety of enemies. All Fighter AI enemies are able to open/break down doors, except Zombies, which are only able to do so during a Blood Moon, and the Psycho, who does not interact with doors at all.

## Behavior

An NPC with the Fighter AI exhibits the following behavior:

* Directly chases the player
* Jumps when necessary or if player is above them enough.
* Navigates through platforms

## Tips

* A level piece of land is ideal for battling Fighters. A fast attacking or heavy knockback-inducing weapon is recommended. A magic weapon which can pierce through enemies multiple times (or indefinitely) is most effective when the player has all Fighters lined up.
* As Fighter AI enemies always try to maintain the same height as their target, creating a large pit with a bridge of platforms (and then standing lower than this bridge) will cause Fighter AI enemies to fall right through it.
* Many Fighter AI enemies are exceptionally vulnerable to  Confused debuff, making them walk away from the player.
* Most Fighter AI enemies can only have doors open *away* from them. They cannot open a door if it is obstructed by a background object (e.g. a workbench) on the opposite side.
