Scrolling background - Sprite Kit

Question

So I tried to create an infinite scrolling background by using this post\'s solution (Sprite kit side scrolling). However, I would want to make the image repeatable. As you

Answer 1

The original logic that has a for loop works fine with minor changes:

for (int i = 0; i < 2; i++) {
        SKSpriteNode * bg = [SKSpriteNode spriteNodeWithImageNamed:@"bgimage"];
        bg.anchorPoint = CGPointZero;
        bg.position = CGPointMake(i*bg.size.width, 0);
        bg.name = @"snow1";
        [self addChild:bg];
    }

And in the update method:

[self enumerateChildNodesWithName:@"snow1" usingBlock: ^(SKNode *node, BOOL *stop) {
SKSpriteNode *bg = (SKSpriteNode *) node;

bg.position = CGPointMake(bg.position.x - 5, bg.position.y);

if (bg.position.x <= -bg.size.width) {
    bg.position = CGPointMake(bg.position.x + bg.size.width * 2, bg.position.y);
}
}];
