first person rpg sword

i am working on a first person rpg. the player will have a sword. i have made the sword and the animation but how do i get it to swing and deal damage i do not already have bots added but i am thinking of downloading scripts to use from the unity resouces page. if you know of any preprogramed bots to use in my game that would also be helpful note i have no experrience in codeing but have used a game engine called "gamemaker" from "yoyo games"
