Looks like the order of your scene objects needs fixing. The objects are drawn in the order in which they are listed in the scene tab.
Try pressing the button with the two yellow arrows to arrange the objects in the correct order corresponding to the object center. That should do it.
Thanks for the input, Esmeralda.
I'm not really having trouble with objects overlapping incorrectly. My character used to walk in front of the objects. I designated a walk to position for objects. That's when the playable character began slipping behind onscreen objects before crossing the object center.
I don't think object drawing order has anything to do with character alignment. Character alignment is decided by the animation center you select for your character and the position on the Y axis that the character walks to opposite any object center.
My character appears behind the tree when his center has not crossed the object center.
Thanks again for any further insight!
