Question by pigaroos · Mar 30, 2019 at 04:11 PM · animatorgetcomponent

GetComponent returning null

I have the following:

 void Start()
     {
         anim = GetComponent<Animator>();
         Debug.Log(anim);
     }

But "anim" returns null. The component is on the same object(s) as the script. I've also tried:

     void Start()
         {
             anim = gameObject.GetComponent<Animator>();
             Debug.Log(anim);
         }

But this also seems to be the same. Any advice would be great!

If the component is on the sam object as the script, there is absolutely no reason GetComponent would return null. You may have attached the script on the wrong gameObject.


Use the following line to print in the console more information. When you will click on the message, the gameObject with the script attached will be highlighted. Click on the gameObject and you will find out whether you have really attached the component.

 Debug.LogFormat(gameObject, "Does {0} have the Animator component? {1}", gameObject.name, anim != null);

I figured it out! for some reason, the GetComponent was being called before the component itself was spawned, as your LogFormat suggested. So I added it to update

     bool gotAnim = false;
 
     void Update()
     {
         if(gotAnim == false)
         {
             anim = GetComponent<Animator>();
             //Debug.LogFormat(gameObject, "Does {0} have the Animator component? {1}", gameObject.name, anim != null);
             gotAnim = true;
         }
     }

and that did the trick. Thanks man!

Components don't spawn after a start function, assigning components can be done at anytime. Have you tried assigning the variable in the inspector ins$$anonymous$$d of doing it within the script?
