Question by daviddickball · Jun 27, 2015 at 10:04 AM · canvasimagenullreferenceexceptionfind

Trying to find() an image in canvas & getting NullReferenceException

I've created a canvas with an image inside, and I want to programatically disable the image. Here's my script: 

 GameObject.Find("AvatarDefault").SetActive(false);

But this returns an error - NullReferenceException: Object reference not set to an instance of an object. Not sure why, because the object is definitely there, and named correctly.

I have been facing similar issues. If I tried to debug whether the parent canvas was found, that was also null!! Worked around by attaching the child gameobjects through the inspector.

If it's a child object maybe try referencing the pathway to it. Something like GameObject.Find("Canvas/AvatarDefault") to reference the image as a child of the canvas If that doesn't work, then I'd say digzou's idea of attaching it through the inspector is the best bet.

I've solved this problem a different way now doing something different, but yeah, crazy that you can't just disable an image the same way as a normal gameobject!

Hey there. If you have an image in a canvas, then you won't be bale to setActive. Images as UI elements only responde to enable = true/false. I don't know why it is like that, but that is how it works
