Resolved UnassignedReferenceException

Hello again. I keep having many other problems, i'm so stressed and i'm thinking about giving up. So please, help me! I know i'm stupid, i don't know anything about C# programming.

 

It literally tells you what's the problem. So open/select the game object has the gun script and drag and drop the bullet game object onto the proper field in the inspector.

 

Yeah, i've read it, now i put the [Resolved] prefix to it, because i don't know how do i delete a thread. I'm gonna do this with the other threads.

 

You cannot delete threads (by design, we preserve them for people come after you), so it is completely okay to tag them resolved.
