Make a triggerzone and rightclick it, in the ifused feild type the name of the enemy
Copy the txt below and save it in "C:\Program Files\The Game Creators\FPS Creator\Files\scriptbank\people" as evil.fpi using notepad.
Quote: ":activated=1,state=0:timerstart,state=1
:timergreater=5000,waypointstate=0:animate=2,waypointstart
:waypointstate=3:animate=2,waypointnext
:waypointstate=4:animate=2,waypointrandom"
Add enemy and change name to what you used in the triggerzone.
Change script to the evil.fpi you just made.

Enjoy.
