How to instantiate an object?

The cube successfully instantiates once, which makes me think there is something happening between the first and second iteration that wipes the GameObject from memory.

That is a PERFECT place to begin your next investigations. Here’s a sample of the thought process:

Why do my Music ignore the Sliders ?

Let me take you step by step through it. You see the error line, line 35? The only possible thing that could be null in that line is audio_BGMusic So that’s part 1. That’s what’s null. We identified it. Part 2… WHY is it null? Well, first we start with “who is supposed to make it not null?” Looking up further I see line 19 sets it, with this construct: audio_BGMusic = ObjectMusic.GetComponent<AudioSource>(); So lets take that apart. How can that fail? We have to suppose it DID fail, so we…

Step by step, break it down, find the problem.

@tim394

it looks like he might have a slightly different problem

The NullRef “problem” doesn’t actually change. It’s ALWAYS the same, no matter where it happens, in your code, in Unity’s code, in someone else’s code.

Therefore the answer really is ALWAYS the same. I’m not kidding. There’s never a NullRef that is fixed by any other way.
