spriteNodeWithColor not appearing in SKScene

I experienced a possibly related problem during the "Intro to SpriteKit" stage of the "Build a Game wit SpriteKit" course. I am also using Xcode 6.0.1. I put the following code into GameScene.m but the green square did not show up in the iOS emulator:

-(void)didMoveToView:(SKView *)view {
    /* Setup your scene here */
    SKSpriteNode *greenNode = [SKSpriteNode spriteNodeWithColor:[SKColor greenColor]
                                                           size:CGSizeMake(100, 100)];    
    [self addChild:greenNode];
}

Then I realized that it does show up once I rotate the iOS emulator into landscape mode. So the green square is there, but simply out of view in portrait mode. The scene's dimensions must be wrong.

This can be fixed by changing line 45 in GameViewController.m from this:

    GameScene *scene = [GameScene unarchiveFromFile:@"GameScene"];

to this:

    GameScene *scene = [GameScene sceneWithSize:skView.bounds.size];

I hope this helps some people to work through the course in Xcode 6.

Hi Aaron,

Thanks for the help with this. I finally managed to get this sorted. I removed the background image I'd set, after that I could see the green square. I did some googling and found it may be the layer ordering. I'm not sure why green sknode wasn't visible as it is the last item added to the scene, however it appears to be getting pushed behind my background image

I fixed this by adding the line for zPosition for the ground node, as below. Apparently this moves the image up the layer hierarchy manually. The documentation I followed is here, from around halfway down the page where the helicopter example is: https://developer.apple.com/library/ios/documentation/GraphicsAnimation/Conceptual/SpriteKit_PG/Nodes/Nodes.html

GroundNode *ground = [GroundNode groundWithSize:CGSizeMake(self.frame.size.width, 22)];
ground.zPosition = +1;
[self addChild:ground];

Hello Lee,

I noticed that you have size:size

Did you define this size somewhere? If not try adding CGSizeMake(100,100)

//Your Code now:
GroundNode *ground = [self spriteNodeWithColor:[SKColor greenColor] size:size];


//example: (Change the size to CGSizeMake(100,100)

SKSpriteNode *greenNode = [SKSpriteNode spriteNodeWithColor:[SKColor greenColor] size:CGSizeMake(100, 100)];

Thanks for the help Aaron, will do.

I wont be able to do this until later this evening (around 7 - 8 hours from now) but will pop a link up once its done

Also, I'm not sure why I have to do this in my project, yet in the sample project from Amit it works without this line. I'm wondering if it is the way the SpriteKit template is in Xcode 6

Thank you Sebastien for this Fix :) I got the same issue .

I was running into the same exact issue as Lee Hardy has described. I found that in GameViewController.m, changing skView.ignoresSiblingOrder from YES to NO solved the issue for me (running Xcode 6.1). YES was the default value from the Xcode template.

Thank you Lee Hardy I had the same issue and your fix worked for me :).
