well i see the WRAP feature:
The Wrap behaviour simply repositions an object to the opposite side of the layout or viewport if it leaves the area. It has no conditions, actions or expressions. The Wrap to property allows you to choose whether to wrap the object when it leaves the layout area, or when it leaves the visible viewport.
The object only wraps once it is fully outside the area, i.e. no part of its bounding box is in the layout or viewport area.
But as you can see it doesnt allow tile or entity to be in two places at once : take a look at the demo at the bottom of this page and you ll see what i mean, but id need that functionality for entities, pickup, platforms and backgrounds :( (the player remains in the center of the screen)
Good news is id only need wrap in the x not the y too :-D
cvp demo is under the title : THe wrapping (near bottom of page)
