void Start()

Is it possible using the void Start() function to position the camera location and rotation so I could just drag 'n drop the C# script onto the camera asset so when I click run it positions the camera at the correct location?

Do you mean while the game is running?

Yes, I would like the camera to shift from the default location to the new updated location in the void Start() function while the game is running.

Maybe use a if statement in the update funktion in your camera script. And add a button with void onGui. If you push the button a bool variable = true and if its true the position and rotation will change.

I’d like to know how to change the camera location and rotation in the void Start() function

Change the transform.position and the transform.rotation

That’s what I’m trying to figure out how to do.

If you already know the position and rotation you want it to have, you literally just say

transform.position = myDesiredPosition;
transform.rotation = myDesiredRotation;

If you’re trying to figure out how to calculate the appropriate position and rotation, then it depends what you are trying to accomplish

If you know that the desired camera position isn’t going to change in the future, then your simplest option is probably to position a camera manually in edit mode and use the camera preview to align it exactly where you want it, then just copy the position and rotation values from the inspector into your code.

If you’re trying to position it automatically according to some rules (like “focus on the player”), then you will have to formalize those rules and translate them into code so that the computer can follow them.

position is a Vector3, you gotta give it a x, y, z coordinate.
so transform.position = new Vector3(x, y, z) or someGameObject.transform.position

rotation is a Quaternion, but if you use Quaternion.Euler you can give it an x, y, z rotation as well.
so transform.position = new Quaternion.Euler(x, y, z) or someGameObject.transform.rotation.

all you need is a location you want to place the camera on. you can make this either a gameobject in the scene or a vector3 variable. same thing for the orientation.
