A Boolean value that indicates whether parent-child and sibling relationships affect the rendering order of nodes in the scene.
- iOS 7.0+
- macOS 10.9+
- tvOS 9.0+
The default value is
false, which means that when multiple nodes share the same z position, those nodes are sorted and rendered in a deterministic order. Parents are rendered before their children, and siblings are rendered in array order. When this property is set to
true, the position of the nodes in the tree is ignored when determining the rendering order. The rendering order of nodes at the same z position is arbitrary and may change every time a new frame is rendered. When sibling and parent order is ignored, SpriteKit applies additional optimizations to improve rendering performance. If you need nodes to be rendered in a specific and deterministic order, you must set the z position of those nodes.
