The name of the tilemap, used to set the name on the MapData.
The Weltmeister JSON object.
Controls how empty tiles, tiles with an index of -1, in the map
data are handled. If true, empty locations will get a value of null. If false, empty
location will get a Tile object with an index of -1. If you've a large sparsely populated map and
the tile data doesn't need to change then setting this value to true will help with memory
consumption. However if your map is small or you need to update the tiles dynamically, then leave
the default value set.
Parses a Weltmeister JSON object into a new MapData object.
