def render(self, level, x, y, minx, miny, maxx, maxy, fov_map, main_area, *args, **kwargs):
"""
Renders current level.
Takes the level map and draws each tile on it, according to
its properties.
Since the map may be bigger (or smaller) than the screen, it
makes some calculations to center (or try it at best) on the
given (x,y) coordinates.
TODO:
- draw level objects. It just draws the map (and the player
but just in a testing manner)
- instead of drawing from level.mapa, ui.py should call a
draw routing in the wrapper, which should receive the
contents to be drawn in a specific area, without any game
details being revealed here. This would also remove the
previous message() method
Arguments:
level : the world.level with the map to render
(x,y) : the coordinates to be the center of the drawing
(minx,miny) : the minimum coordinates from the map to be drawn
(maxx,maxy) : the maximum coordinates from the map to be drawn
fov_map
main_area : the area where the map is to be drawn
