Question by M0n5t3r · Apr 03, 2015 at 01:23 PM · valuemethodtypegroupexpression

Expression denotes a `method group', where a `variable', `value' or `type' was expected

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class Truster : MonoBehaviour {
 
 
     void Update() {
 
         if (Input.GetKey (KeyCode.LeftControl)){
             GameObject.Find("sphere 2").GetComponent.AddRelativeForce(Vector3.down * 2);
         }
 
     }
 }


Why do I get this error? Expression denotes a method group', where a variable', value' or type' was expected

NullReferenceException: Object reference not set to an instance of an object Truster.Update () (at Assets/Scripts/Thruster Scripts/Truster.cs:11)

The problem is, that the thruster cannot have rigidbody. Since if I do that, the whole thing would like "explode" and fly away.

But my sphere is not allowed to get a rigidBody, because than it would explode.

Should I maybe use Angles. And add force to one of the angle's of the white block?

If your sphere doesn't have a Rigidbody on it, then why are you trying to gain access to a component of type Rigidbody on it?

If a GameObject has a rigidbody, then you should isolate your Find/GetComponent to that part of the gameobject(s). If there isn't a Rigidbody whatsoever, then this will never work for all the obvious reasons. It's impossible to start a car without a car, it's no possible to AddRelativeForce to an object that doesn't have the corresponding component.

I think your call of GetComponent is wrong.

try like this :

GameObject.Find("sphere 2").GetComponent().AddRelativeForce(Vector3.down * 2);
