Switch between parents - SpriteKit

Question

In my game I have two SKNodes called "Center" rotating. I have several objects as the child of Center (the SKNode). I did this so I could let these objects orbit around Center. Although at certain points I want to switch to other SKNodes - "Center2". In this I have named one of the objects "Onject", which switched between parents I need to attach and detach at certain points in my game. I have tried, after doing self.addChild(Object) then doing Center.addChild(Object). My game crashed.

How do I switch between parents for objects?

Answer 1

there is a method called move(toParent:SKNode) to do exactly what you want, it will also fix the coordinates for you.

Answer 2

If you call self.addChild(Object) and then Center.addChild(Object) your game will crash, because the object will then have two parents. You cant add the object twice as a child for different nodes.

If you want to switch the parent, you have to remove it first from its parent, so the flow will be as follows:

• self.addChild(Object) (then just perform your game logic)

once its time to switch the parent, follow these steps:

• Object.removeFromParent()
• Center.addChild(Object)

Then your object has a new parent
