In the for loop they use a hardcoded set form 0-3 this set could be an iterator to improve memory usage.

The code below is a good example of how this code is well documented but not well commented. There is no explanation as to how the danger score is being used. While I appreciate the headers in cases like this they don't help the reviewer understand why things are the way they are.
## Returns an integer score in range 0 - 100 for given file (100 = good, 0 = bad).
def rate_tile(self, tile_coordinates):
danger = self.game_map.get_danger_value(tile_coordinates)
if danger == 0:
return 0
score = 0
if danger < 1000:
score = 20
elif danger < 2500:
score = 40
else:
score = 60
tile_item = self.game_map.get_tile_at(tile_coordinates).item
if tile_item != None:
if tile_item != GameMap.ITEM_DISEASE:
score += 20
else:
score -= 10
top = (tile_coordinates[0],tile_coordinates[1] - 1)
right = (tile_coordinates[0] + 1,tile_coordinates[1])
down = (tile_coordinates[0],tile_coordinates[1] + 1)
left = (tile_coordinates[0] - 1,tile_coordinates[1])
if self.game_map.tile_has_lava(top) or self.game_map.tile_has_lava(right) or self.game_map.tile_has_lava(down) or self.game_map.tile_has_lava(left):
score -= 5 # don't go near lava
if self.game_map.tile_has_bomb(tile_coordinates):
if not self.player.can_box():
score -= 5
return score
In the below code a static mapping of cardinal directions appears again. Considering it's a static type and used in a number of locations it should be defined as other elements of the code are.
def number_of_blocks_next_to_tile(self, tile_coordinates):
count = 0
for tile_offset in ((0,-1),(1,0),(0,1),(-1,0)): # for each neigbour file
helper_tile = self.game_map.get_tile_at((tile_coordinates[0] + tile_offset[0],tile_coordinates[1] + tile_offset[1]))
if helper_tile != None and helper_tile.kind == MapTile.TILE_BLOCK:
count += 1
return count
This is an odd choice rather than deleting the AI player object it continues to live and waste CPU cycles.
line 4738
def play(self):
if self.do_nothing or self.player.is_dead():
return []
........
Again in the below an iterator could be used instead of a static array.
for direction in (0,1,2,3):
score = self.rate_tile((current_tile[0] + tile_increment[direction][0],current_tile[1] + tile_increment[direction][1]))
........
At this point, I should mention in the play function each action choice has a section of code associated with it. Each one of these sections could be split off into another function. This isn't necessary but rather a stylistic choice.
In the below code range should be xrange() as to not generate and store a set but to rather use an iterator.

if not self.game_map.tile_is_walkable(current_tile) or not self.game_map.tile_is_withing_map(current_tile):

This is a long function that could be decomposed into smaller actions. process_inputs

This if statement is really wordy and has a lot of repetition. Would make sense to create a helper method for min(len(...))

This is a great example of a large class code smell, in order to instantiate a Player class, 32 different fields need to be accounted for. This could be refactored or extracted to a subclass in order to make the code more readable.

This method has a lot of glaring issues, first and foremost, this method has the inappropriate intimacy code smell written all over it. In constantly calls the methods of the map class, meaning that any changes made to either class is going require major refactoring within the other.
Line 556
Utilizing a huge wall of switch statements like this makes the code much harder to read and will cause considerable trouble to refactor. Extracting this to sub-method that handles the logic would help considerably.
