How do you make a part rotate with a characters rotation?

For example, if I wanted to make a mirror script, and a player in first person rotates while staying still, and a cloned NPC in front of that player will also rotate and copy his rotation. How can I do this?

There is a mirror tutorial in Lua Learning, however if you are looking for an all around thing, I wouldn’t know.

Okay, thanks, i’ll check it out
