I'm still confused about persistent data.
Let's say I have an arraylist in one scene that will control an inventory. If I want to reference that array list in another scene to add/remove objects, how do I do that? I know I can put this information into a loader and it will persist across all scenes, but how do I set up my FSMs to refer to that in development?

Have you tried setting the object your inventoryarray/table is attached to as a global variable, putting the object as "dontdestroyonload" and then referencing the global variable in your FSMs?

For example you have two GameObjects, Object A and B.
Arraylist with a reference "inventory_items" is on Object A.
If both GameObjects are active and Object A will be frequently used, on Object A, in the start state you do a "Get Owner" and store Object A as a global variable. Now on Object B to get that array all you have to do is use any arraylist action, and in the array owner select the Object A global variable, and put reference "inventory_items". Also as marv suggested, to persist a gameobject through scene, you want to make it dontdestroyonload
Now... You don't want to use global variables for every GameObject in the game... So for less important objects u can tag them, and use gameobject.findwithtag, and in playmaker I believe it's Find GameObject, but instead of putting the name in, you put the tag in.
Also an interesting tip: If you want to get a deactivated object, you can use get child instead of find gameobject. In my app I use this quite frequently because it's only one scene, but it has +10,000 levels and if you try to use find game object on a dedicated game object it will simply not find it.

Hi,
Maybe using easySave would be easier, then it would persist both in game when swithching scenes and in dev and when app is shutdown and reopen.
Bye,
