Nope, I think i explained it badly.
The player object obviously moves around, I have set up a Line of sight behaviour, so that when the player is near the enemy it starts chasing it. If I use the pathfinder behaviour the bad guy moves greatly but it stops when it reaches the position where the player was at the start of the pathfinding. If I use bullet + rotation it moves diagonally, the thing I don't want it to do.
However, you got the concept of the movement. I can't figure out how to do it.
