Saving the state of multiple sprites

[jallison22]

I am working on an ios 10 app in which users can instantiate new SKSpriteNodes and drag thenm around a view altering several SKSpriteNode properties. What would be the best approach to saving this set of child SKSpriteNodes in such a way that the view can be recreated when the app is re-opened. Ideally it would be great if the user could pick from a thumbnail of the saved view to re-load it. thanks, JA

Hi @jallison22! I’m not too familiar with SceneKit itself however might be able to help with some general tips on the subject

SKSpriteNode objects conform to NSCoding so you might be able to serialise your state using NSKeyedArchiver and NSKeyedUnarchiver. You can find more on this by taking a look at the Apple Docs or our old tutorial

We also have another (again, slightly old) tutorial on saving game data that might be able to help: https://www.raywenderlich.com/63235/how-to-save-your-game-data-tutorial-part-1-of-2

Hope this helps! Let me know if there is anything else I can help with
