[Danny Boy]

i don't want to be any near of being rude but i already know that but i just don't how to do it correctly. and plase if you are going to reply don't just say "add a path node" because i already know that too and that lead me to nowere. what i want to know is how do i make a enemy walk to the pathnodeA then pathnodeB, C, D etc... but i don't how because in the way i have done it it does not work well, has i have said before.
