pathfinding.

hi all . i'm working on some IA for the monster of a TopDownShooter.

i would like to use pathfinding to make the monster go away from the player, but i dont know how.

how i can tell "find a way to a point 400 pixel away from player.x;player.y " for example.

anyway i would take any advice on how to use pathfinding in advanced manneers.

because all i can do know is pretty much go toward the player.

;

i used a random variable to make the monster go near the player instead on directly on him but that all.

if you have some ideas, be sure i will be interested.

thanks
