Camera following/looking at aircraft

Still doesn't work.. When I add:

Camera.main.transform.LookAt (transform.position);

The camera doesn't rotate with the aircraft anymore when it rolls..

Oh, I see, when it rolls too. Don't use LookAt, LookAt will make the camera face towards the aircraft from the position that it's in. What you want to do is move the camera to the position as described above, but match the aircraft's angle of rotation, like the code in your original post.

Yeah, but when I do that, the camera looks 'over' the aircraft in s$$anonymous$$d of 'at', because the camera is higher than the aircraft..

Ahhhh okay, I gotcha. Okay, create a new public Vector3 called "RotationOffset" and set it to the additional degrees that you'd want your camera to face; for example, if you want it to face ten degrees down, do new Vector3(10f,0f,0f); or something like that. It's public, so you can play around with it.

Now, add that rotation vector to your current rotation target. So ins$$anonymous$$d of just

 Camera.main.transform.rotation = Quaternion.Lerp(Camera.main.transform.rotation, transform.rotation, 5f * Time.deltaTime);

Try doing

 Quaternion RotationTarget = transform.rotation * Quaternion.Euler(RotationOffset);
 Camera.main.transform.rotation = Quaternion.Lerp(Camera.main.transform.rotation, RotationTarget, 5f * Time.deltaTime);

So you create the RotationTarget by adding the transform.rotation and Quaternion from the Euler of RotationOffset. (Euler is how you convert a Vector3 to a Quaternion. Also, you add two Quaternions by multiplying them together. Math! More info: http://answers.unity3d.com/questions/130510/add-or-substract-two-quaternionsrotations.html )

Hopefully that works!

Great solution! Thank you so much! Have a nice day.
