regarding Containers, the doc I see here: scirra.com/manual/150/containers seems to say that each object has a Container property, to which I can link more objects.
So I could have a background object that in its Container holds multiple cards
I want to have a Behavior that shuffles the locations of the linked items (not of the parent item that has the Container property), with a property to do it in a time interval and also be able to invoke the behavior on-demand.
Of course, if there is no API currently to enumerate items in a container, it would be nice to have that, since one could use Containers for more stuff then (like for making logical graphs). In fact containers could have an option on whether they treat all objects as one (as they do now), or if they're just a logical grouping (used in EventSheets by enumerating linked objects or used by behaviors)
btw, what I found on the forums was code to shuffle arrays, don't want to do that, want to have the simplest way to shuffle objects around in the layout (this is more of a design goal, to make a reusable thing for such games, I know myself how to shuffle stuff in code)
