FPS Controller Confusion...
Hello, I am currently following this tutorial about FPS controller movement. I am a beginner. https://www.youtube.com/watch?v=DzO270DH0tk
For the function LookRotation() , where it says Quaternion camTargetRotation and Quaternion bodyTargetRotation; why do we put -camRotationY on the X Axis of the Vector3? Same with bodyRotationX, why do we put it on the Y Axis of the vector3? Wouldn't it make sense for them to be put on their corresponding vector3? I'm a beginner so I don't really understand why this is happening.
Thank you.

//Hides cursor when game entered
Cursor.visible = false;
Cursor.lockState = CursorLockMode.Locked;
//Get camera and body rotational values
bodyRotationX += Input.GetAxis("Mouse X") * camRotationSpeed;
camRotationY += Input.GetAxis("Mouse Y") * camRotationSpeed;
//Stop our camera from rotating 360 degrees when looking up and down
camRotationY = Mathf.Clamp(camRotationY, cameraMinimumY, cameraMaximumY);
//Create rotation target and handle rotations of the body and camera
Quaternion camTargetRotation = Quaternion.Euler(-camRotationY, 0, 0);
Quaternion bodyTargetRotation = Quaternion.Euler(0, bodyRotationX, 0);
//Handles rotation
transform.rotation = Quaternion.Lerp(transform.rotation, bodyTargetRotation, Time.deltaTime * rotationSmoothSpeed);
cam.localRotation = Quaternion.Lerp(cam.localRotation, camTargetRotation, Time.deltaTime * rotationSmoothSpeed);
}
