how to make the camera follow the mouse cursor just like crosshair in counter-strike?

Unity Engine

can someone give me hints about getting the mouse cursor coordinates then gives in to the center of the camera or a gameobject that is centered in the camera will accept the coordinates?

uhh… why Rect?

because we need to get coordiantes of the center of screen.You can do it with raycast too Unity - Scripting API: Camera.ScreenPointToRay

var positionn : Rect; 
var crosshairTexture : Texture2D;
function Update() {
Screen.lockCursor = true;
}

function OnGUI () {
      //this line generates the mouse pos
    positionn = Rect( Input.mousePosition.x - (crosshairTexture.width / 2), (Screen.height - Input.mousePosition.y) - (crosshairTexture.height / 2), crosshairTexture.width , crosshairTexture.height );
   //draws the texture to mouse pos
    GUI.DrawTexture( positionn , crosshairTexture );

}
