Baddies 2.8–Map

The map is just a list of lists, holding all the tiles in a matrix. The only thing it has special is the fact that it holds the tileset image, with all the images of the tiles, as well as other extra graphics used for other drawing modes (for example the grid). When the map wants to draw the tiles (be it as the actual tiles, or the grid, or the collision) it passes the corresponding graphic to the tiles in their draw function.


The map tiles are not nodes because of the need to access them easily with a 2D coordinate system, and the special operations that we need to do with them. It’s one of the cases where efficiency is more important than following the tree structure.
