Sorry for english.
use gridgraph for 2D game.
In some case, i need to change the map's scale. like to (2,2). in order to fit the unwalkable zone. i also changed the graphupdatescenes' scale to (2,2,2) too. The editor shows the unwalkable zone i made by graphupdatescenes scaled very well. However the result after scanning is totally wrong. It seems the gridgraph only recorgnize part of the zones.
