[PyGame] finding local area in dictionary

[deanhystad]

You could use dict.get(key, value). This returns a special value (default is None) when the dictionary lookup fails. Here I make a list of all possible near tiles, then remove all missing tiles.

def find_local(self):
    x = self.rect.centerx // self.game.level.tilesize
    y = self.rect.centery // self.game.level.tilesize
    tiles = self.game.level.tile_dict
    return [t for t in [tiles.get((i, j)) for i in range(x-3, x+3) for j in range(y-3, y+3)] if t]
