Here is the simple logic that @Everynone suggested once to me that gets the enemy player to seek your player. It works pretty good. The problem is it seems it is only good for the first life of the player and possibly other things and then the players stop walking, and stop attacking.
Since this is a Beat Em Up template, here is the logic to make the enemy player instantly turn left and right like most Beat Em Up games.
And when I stopped it I was getting accessed none and pending kill errors.
