It can't find a gameobject, but it's right there.

Here, I have absolutely no idea what is wrong. It seems to work for other people, though.

 

You need to tell it exactly what SimpleObject is somewhere. It doesn't automatically find it in your hierarchy. One approach would be declaring it at the top like this:

Code (CSharp):

1. public GameObject SimpleObject;

Then assign it to the component in the inspector.

OR, you could search the hierarchy for it like this:

Code (CSharp):

1. GameObject.Find("SimpleObject").GetComponent<NotHotAudio>().AudioPlayer();

But that's generally not as good for performance and won't tolerate moving things around/renaming/whatever, as well as the first option will.

 

I'm stupid, I should have realized that even as a beginner. I found out myself, though. But I am very pleased and thankful you sent a message about it!
