How to rotate an SKSpriteNode around the node's Y-axis?

Question

I\'m trying to rotate an SKSpriteNode node around it\'s Y-axis. I know there\'s the zRotation property and that will rotate the node clockwise or counter-clockwise; however,

Answer 1

SpriteNode *spriteNode = [SKSpriteNode spriteNodeWithImageNamed@"Sprite"];
spriteNode.position = position;

SKAction *action = [SKAction repeatActionForever:[SKAction customActionWithDuration:duration actionBlock:^(SKNode *node, CGFloat elapsedTime) {
    node.xScale = sin(2 * M_PI * elapsedTime / duration);
}]];

[self addChild:spriteNode];

However, the sprite looks like having no thickness.
