I've looked through the scripting guide, and I'm not sure what function I want for this. Vector3.Angle sounded like it was the one, but it doesn't behave as I was expecting. I'm making a game on a 2D plane, using C#. I have an enemy missile object that should check in what direction the player is from it, compare that with the direction the missile is facing, if the player is to the left, turn left, if the player is to the right, turn right. It's just the bit about finding the direction from the missile to the player I'm unsure about. Thanks for any help you can give.
