Tilemap wrapping

Hello,
Is it possible to wrap a tilemap? For example, for a horizontal scroller with random generated level, use fixed size tilemap for background, and update only one column of the map during scroll ? I’m going to port old game project, which was built using my own tilemap engine, with such feature (map was accessed by a fetcher where map cell offset index was calculated modulo map bounds) . The other solution for is to copy all the columns of whole visible area every time when new column must be added on the side, but something easier/automatic would be better.

You can access and set individual tiles in a tilemap from script. Check out http://www.defold.com/ref/tilemap
