c# - Unity 3D scripts move multiple objects -

i have problem. i'm doing project in unity 3d (c#), 3d worlds editor. problem want move multiple objects selecting them. managed move 1 mouse cursor, multiple failed :d code move 1 :

public class clickanddrag : monobehaviour {     private raycasthit raycasthit;     private gameobject gobj;     private float distance;     private vector3 objposition;     private bool bobj;      // use initialization     void start() {     }      // update called once per frame     void update() {         if (input.getmousebutton (0)) {             var ray = getcomponent<camera> ().screenpointtoray (input.mouseposition);             var hit = physics.raycast (ray.origin, ray.direction, out raycasthit);              if (hit && !bobj) {                 gobj = raycasthit.collider.gameobject;                 distance = raycasthit.distance;                 debug.log (gobj.name);             }              bobj = true;             objposition = ray.origin + distance * ray.direction;             gobj.transform.position = new vector3 (objposition.x, objposition.y, objposition.z);         } else {             bobj = false;             gobj = null;         }            } } 

thanks help!

private gameobject gobj; variable single gameobject. reformat private list<gameobject> objects; , instead of gobj.transform.position = new vector3 (objposition.x, objposition.y, objposition.z) this:

foreach (gameobject item in objects) {     item.transform.position = new vector3 (objposition.x, objposition.y, objposition.z) } 

edit: in case aren't sure how manipulate list, list<t> has set of built in functions make easy. can call objects.add(newobject); add object, , objects.remove(oldobject); remove object.
