I think the one with the arrows is Restore Purchases and the one with the colorful circles is for GameCenter. And yes, both can be done in Buildbox 2, I guess in Buildbox 3 as well...
Thanks, but how can I implement them? I have searched for them in Buildbox 2 interface editor but haven't found.
It's easy, go to the world UI, and from the left panel under "Buttons" there is a navigation one, drag and drop it into the scene, and from the right panel, there is "Function" click on it and choose "Restore purchase".
