is there a entity to make a npc look were you want?

is there an entity that i can use to make my npc's eyes look were i want (at the character or at the camera?)

I suggest you look at the tool in the sourceSDK called Faceposer.

This tool allows you to do a lot of extra things with npc's, including making them look at entities.
