I need to constrain the scrolling, so that the scrolling of the map stops when the edges of the viewport’s reaches the background edge. So that the background becomes the perimeter of the map, and the user never sees beyond its edges.
On the image the light green area represent the background element, the dark green the viewport. I need to constrain the viewport so that it only can move around in the background area.
Is this possible?
Thx
