well, you may use my own script. it was my first try to write an AI-script. i copied it from my old project and set comments. I dont know how experienced you are in programming c-script in general, so just ask if you have a question about this^^
the action guard will let the npc turn towards the player if he steps into his field of sight, and stop before him, attack until the player runs out of sigth or one of them dies. i also included some effects, like a random choice out of 6 different deathscreams, so the guards arent all the same. you must include 6 sounds for this or erase the part of the script about the deathscreams.
in addition to this, a music will start playing at low volume when the npc starts following you and become louder; if the guard dies the music decreases its volume and stops.
but before you can use this script, you will have to define everything, like variables, the skills for speed, health and damage and the sounds. i defined all this in another script and didnt want to do the work to write this again just for posting it here. the script should work fine like it is posted (hopefully), after you defined everything.
if a project using this AI goes public, i want to know and be credited^^

i used the animated version of the guard.mdl the gamestudio offers, so the animations are specially prepared for this modell.
i hope it works as claimed^^
