How to do camera scrolling?

I would like to make a 2D scrollable map using camera scrolling, however I have no idea on how should I go about doing it. Can anyone help me with this? Thanks.

Doing some tutorials will be very helpful for you if you have no idea how to at least do it.

I assume your map is on the x,z plane.

float pan_speed = 10.0f;

function Awake(){
camera.y = 100; //put the camera above the world
camera.Rotate(transform.right, 90); // transform the camera on
}

function Update(){
if(Input.GetKey("up"))
  camera.Translate(Vector3.forward * Time.deltaTime * pan_speed, Space.World);
if(Input.GetKey("down"))
  camera.Translate(-Vector3.forward * Time.deltaTime * pan_speed, Space.World);

if(Input.GetKey("left"))
  camera.Translate(-Vector3.right * Time.deltaTime * pan_speed, Space.World);
if(Input.GetKey("right"))
  camera.Translate(Vector3.right * Time.deltaTime * pan_speed, Space.World);
}

Thanks a bunch, @LyanApps ! I changed a little bit of the codes for the "up" key and "down" key and placed them inside void OnGUI() though and it works (: void OnGUI () { if ( Input.GetKey("up") ) { Camera.main.transform.Translate( Vector3.up * Time.deltaTime * scrollSpeed, Space.World ); } if ( Input.GetKey("down") ) { Camera.main.transform.Translate( Vector3.down * Time.deltaTime * scrollSpeed, Space.World ); } }

Is it possible to set a limit as to how much the camera can be scrolled? And how do I go about doing it?
