Acto State component

is there a component which helps you track down the actor state as in : idle, attacking, searching, chasing etc. ? I dont want to create boolean variables for all possible states a character can have.

Unless your character can be in more than one state at once, create your own enumerator.

thanks for your reply but enums are reallly basic. I want functionality with states. I would like to have events when the transition starts or ends.

Gameplay Tags could work for that.

can you explain a bit ?
