SKSpriteNode think's it is (null) after initialization
I have a SKSpriteNode that I initialized with this code
//viewDidLoad
bullet = [SKSpriteNode spriteNodeWithImageNamed:@"missile2"];
bullet.xScale = 1;
bullet.yScale = 1;
bullet.position = CGPointMake(67, 148);
bullet.zRotation = M_PI;
[self addChild:bullet];
In a previous question, I asked why I can't set it's position, we determined it was because the sprite was null, when I logged NSLog(@"bullet is %@",bullet);
Here is a link to that question.
Sprite position not working in Objective C, Xcode
My question is, why does Xcode think this sprite is null when I am initializing it in viewDidLoad?

I guess you are just invoking
NSLog(@"bullet is %@",bullet);
before the bullet property is initialized.
Maybe you put the NSLog line inside the init right? That would be an explanation since init does happen before viewDidLoad.

I don't completely understand what happened, but I got it to work. It turns out I was calling a method from another file the wrong way, I must have been initializing it again, because all my variables were set to 0. I called the method a different way and it worked.
