Just a quick update. Qiso now includes 3 new functions: getCameraPanRange(), setCameraPanRange(), and releaseCameraPanRange(). Using setCameraPanRange() you can now define the northern most and southern most tiles of a rectangular region within the map, and camera panning will be restricted to within this zone. Useful for creating restricted play areas within larger maps, so that the scenery can go off beyond the screen edges and give the illusion of a bigger world.

This has literally just been pushed live so allow for an hour or so before Corona’s build servers synchronise.
