class LevelState(GameState):
"""
This state is where the player will move the hero around the map
interacting with npcs, other players, objects, etc.
Expects to load a specially formatted TMX map created with Tiled.
Layers:
Control Tiles
Upper Partial Tiles
Lower Partial Tiles
Lower Full Tiles
The control layer is where objects and boundries are placed. It will not
be rendered. Your map must not have any spaces that are open. Each space
must have a tile in it. Blank spaces will not be rendered properly and
will leave annoying trails on the map.
The control layer must be created with the utility included with lib2d. It
contains metadata that lib2d can use to layout and position objects
correctly.
