Im wondering how to implement multiple grids below the root grid (top level). Ok lets say you have your beggining root grid on top that represents a world map (default depth 0?). Now lets say we wanted towns as a grid to enter. Also dungeons, gates to other worlds, random chest, etc.
So my question is would it look something like this?:
root grid (world map or whatever you want to call it)- depth 0 (default?)
towns- depth 1
dungeons- depth 2
planar gate- depth 3
chest- depth 4
house- depth 5
etc.- depth 6 and so on...
...even though these some of these grids are connecting on the same depth 0 root grid, some may have entries or connections to other grids. Like chests in dungeons, houses in towns, etc.
Or would they looks something like this?:
root grid- depth 0
towns- depth 1
dungeons- depth 1-50
planar gate- depth 1
chest- depth 1
house- depth 1
etc.- depth 1- (how ever many 'levels' that grid will have)
I hope what Im trying to ask makes sense. Basically does each grid have to have a unique depth or can they share depths, but have separate areas.
