Question by Fat_Tony_Productions · Oct 24, 2015 at 09:52 PM · c#gameobjectlight

Can't add game object to script

I am brand new to C#. I am currently doing the tutorial at: https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/coding-for-the-absolute-beginner . For some reason I cannot drag the directional light to the script, nor add it manually by clicking the dot next to "My Light." Any help is appreciated. Here is the current script that I am using:

 using UnityEngine;
 
 using System.Collections;
 
 public class Light : MonoBehaviour {
     
     public Light myLight;
     
     void Update () {
         if (Input.GetKeyDown ("space")) {
             myLight.enabled = !myLight.enabled;
         }
     }
 }

I can't get the quotes to work right.... Sorry

Well the problem is that you have called your script the same name as the Light type.

I'd recommend you rename your script.

  using UnityEngine;
  using System.Collections;

  // Rename script, problem solved. Rename your file to LightToggle also.
  public class LightToggle : MonoBehaviour {
      
      public Light myLight;
      
      void Update () {
          if (Input.GetKeyDown ("space")) {
              myLight.enabled = !myLight.enabled;
          }
      }
  }

Or, if you really, really want to go down that dark path, you need to fully qualify the Light type or it will think you want a reference of your script instead of a Unity light.

  using UnityEngine;
  using System.Collections;
  
  public class Light : MonoBehaviour {
      
      // You can fully qualify Light, BUT, 
      // I HIGHLY recommend you rename your script instead.
      public UnityEngine.Light myLight;
      
      void Update () {
          if (Input.GetKeyDown ("space")) {
              myLight.enabled = !myLight.enabled;
          }
      }
  }
