I'm learning SpriteKit and as an example I tried to add few SKSpriteNodes on the scene each with a label. Here is how my node graph should look (code sample is below):
Scene
|
+-- SpriteNode1
| |
| +-- SpriteNode2
| +-- LabelNode1
|
+-- SpriteNode2
|
+-- SpriteNode3
+-- LabelNode2
According to the documentation from Apple SpriteKit should render SpriteNode1, then its children, then SpriteNode2 then its children. However the rendering result that I got clearly shows that SKLabelNodes are rendered after the other elements, so the label in the SpriteNode1 overlap label in SpriteNode2.
What I tried to achieve is to draw a simple playing card with text on it.
Here is what rendering result looks like:
Here is a code snippet:
-(void)didMoveToView:(SKView *)view {
[self addDummyNodeAt: CGPointMake(500, 500)];
[self addDummyNodeAt: CGPointMake(550, 520)];
}
-(void)addDummyNodeAt: (CGPoint) point {
// Create a sprite
SKSpriteNode* sprite = [[SKSpriteNode alloc] initWithColor:[self getRandomColor] size:CGSizeMake(165, 220)];
sprite.position = point;
[self addChild:sprite];
// Add another color rectangle as a node to a sprite
SKSpriteNode * testNode = [[SKSpriteNode alloc] initWithColor:[self getRandomColor] size:CGSizeMake(120, 50)];
testNode.position = CGPointMake(0, 0);
[sprite addChild: testNode];
// Add a text
SKLabelNode *cardLabel = [SKLabelNode labelNodeWithFontNamed:@"Tahoma"];
cardLabel.text = @"This is a text";
cardLabel.fontColor = [SKColor blackColor];
cardLabel.fontSize = 12;
cardLabel.position = CGPointMake(-22, -70);
[sprite addChild: cardLabel];
}
-(UIColor*) getRandomColor {
CGFloat hue = ( arc4random() % 256 / 256.0 );
CGFloat saturation = ( arc4random() % 128 / 256.0 ) + 0.5;
CGFloat brightness = ( arc4random() % 128 / 256.0 ) + 0.5;
return [UIColor colorWithHue:hue saturation:saturation brightness:brightness alpha:1];
}
