Problems making a smash bros like camera

Questions & Answers
1

I am trying to make a camera that acts like the camera in super smash bros.

It will keep all players on screen by moving horizontally and vertically, and by zooming in and out.

(edited for brevity. click the history button if you need to see it for some reason)

Any help would be appreciated. Thank you in advance.

My suggestion : You need to do tutorials provided by unity http://unity3d.com/learn/tutorials

public bool canFocus = true ;
//You could play with the zoomValue in inspector in play mode
[Range(1f , 100f)]
public float zoomValue ;

private Camera _camera ;

void Start()
{
    if (!_camera)
        _camera = Camera.main ;
}

void Update()
{
    if (canFocus)
    {
        //call the function from below as per your camera ;
    }
}

//Orthographic projection is used for 2D games
void FocusInOrthographicView()
{
    //See your Main Camera setting If the projection is set to Orthographic use this
    _camera.orthographicSize = zoomValue ;
     
}

//Perspective projection is used for 3D games

void FocusInPerspectiveView()
{
    //Is the projection is set to Perspective use this
    _camera.fieldofView = zoomValue ;
}

The Tanks tutorial has exactly this type of camera, you should be able to adapt it to your needs quite easily.
