c# - How to make enemies follow the player all around the screen in XNA? -


okay, i've got code make enemies follow player in xna game, follow player until player in front of them. if player moves past enemy, stop moving towards him. instead continuously move , down player.

the code i've used this:

         vector2 direction = player.position - goblins[i].position;          direction.normalize();          vector2 velocity = direction * goblins[i].enemymovespeed;          goblins[i].position += velocity;

(ignore goblins bit, i've replaced graphics)

not entirely sure go it, ideas?
