You have three options for map scrolling:
The first is possibly the easiest since you don't need to use a ScrollingManager layer. You simple call map.set_view(x, y, w, h) on your map layer giving the bottom-left corner coordinates and the dimensions to display. This could be as simple as:
map.set_view(0, 0, map.px_width, map.px_height)
If you wish to have the map scroll around in response to player movement the ScrollingManager from the cocos.scrolling module may be used.
