NPC combat

[skillmaster19]

I have created a NPC that you can kill by slashing it three times, and respawns in a different spot after 5 seconds of dieing(also shows the dead gani.)

However, I am stuck with making the NPC actually fight and kill the player. where are the scripts documented that I would best use to make the NPC follow the player/ walk around, swing its sword, shoot a projectile such as an explosive, etc?
