Question by navadeep2011 · Apr 30, 2013 at 12:38 PM · raycastmouse

how can i Find an object height, while click on that object?

Hi All,

In a scene i have 3 different objects. my task is if i click an object i just want to print the height of an object.

i wrote code like this:

   var point: Vector3;
   var duration: float;
   var object: GameObject;
   private var startTime: float = 0;

    function Update(){
 if (Input.GetMouseButtonDown(0)){
     var hit: RaycastHit;
     var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     if (Physics.Raycast(ray, hit)){
         startTime = Time.time;
         point = hit.point;
         object = hit.transform.gameObject;
         
         print(object.name);
         
        print(object.size.y);
           }
 }
  }

After saving it is shows there is no errors but when ever i am clicking the gameobject that is showing an exception.

Object reference not set to an instance of an object

Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.String cacheKeyName, System.Type[] cacheKeyTypes, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.Object[] args, System.String cacheKeyName, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.GetProperty (System.Object target, System.String name) UnityScript.Lang.UnityRuntimeServices.GetProperty (System.Object target, System.String name) NewBehaviourScript.Update () (at Assets/NewBehaviourScript.js:17)

Can i get any help

Thanks in advance

Navadeep

Avoid using reserved keyword, I would think object is reserved and you are doing somehtin wrong with it.

Try using obj instead

EDIT and try

 obj = hit.collider.gameObject;

still, avoid object.

Ok, thanks @fafase. I just modified my code as
