Dilemma with camera

Unity Engine

Hi!

I have next camera system set up:
CameraPivot game object that has position 0,0,0 in world
MainCamera is a child of CameraPivot that has certain position and rotation. Camera is orthographic.

I have next script for controlling camera:

private void Update()
{
    MoveCamera();
}

private void OnCameraZoom(float amount)
{
    MainCamera.orthographicSize = Mathf.Clamp(MainCamera.orthographicSize - amount * Time.deltaTime, minZoom, maxZoom);
}

private void OnCameraRotation(float side)
{
    iTween.RotateBy(pivot, iTween.Hash("y", yAxisRotationMultiplier * side, "space", "world", "easetype", easeType, "time", rotationTime));
}

private void OnCameraMovement(Vector2 axis)
{
    movementInput = axis;
}

private void MoveCamera()
{
    var horizontalVector = pivot.transform.forward * movementInput.x;
    var verticalVector = pivot.transform.up * movementInput.y;
    pivot.transform.position += horizontalVector + verticalVector;
}

To zoom my camera I use orthographicSize.
To move my camera I move pivot on Y and Z axis of object. That way my camera moves the way I want.
To rotate my camera I rotate pivot on Y axis and here’s a thing - camera doesn’t rotate the way I want. I want my camera to rotate when position of Z axis of pivot is 0, because that way it rotates as I want it to, around what you actually see.

What can I do to achieve this?

Ok, I’ve figured it out. Now I move vertically like this
var verticalVector = (pivot.transform.forward / 2f - pivot.transform.right) * movementInput.y;
On both X and Z axis ignoring Y axis. Kinda what I want.
