A Dungeon Demon map contains one or more layers of graphical objects.
Every layer contains a single kind of graphical object. Graphical objects include stamped objects (sprites),
tiled objects (floors), wall objects, polygonal objects, numeric legend items and icon legend items. You can
have more than one layer of a kind, for example you might have stamped atmosphere objects like clouds and smoke
as your last layer but you can also have an objects layer below it that contains chests or other dungeon objects.
You might be asking why would you have more than one layer of the same kind? The answer is to control render order.
An example of this is that you would want dungeon objects (like chests and treasure) to be on top of the dungeon floor
so dungeon objects would be on a higher layer than the dungeon floor and smoke and fog would naturally be on a higher
level still so that those effects would be on top of all of the other objects. NOTE: when you create a new map Dungeon
Demon will automatically create the most common default layers in the most common order, ie. floors, walls, objects, numeric
legend and atmosphere.
The Edit Layers menu tab gives you options for controlling each layer including creation, deletion, renaming, clearing,
moving layers back and forth between each other (to control render order), individual layer grid controls,
edge effects, wall parameters and stamp shadows. These last four options are a bit complicated and will receive their own
help pages to details how they work.
