I have the exact same code as Kenneth and yet I'm still able to see the 'X'. What am I doing wrong? I've tried running the code on other text editors and it's the same result. Calling game.log shows me that locations for monster, door, and player are logged, but has no affect in hiding it when the code is run.
import logging
import random
logging.basicConfig(filename='game.log', level=logging.DEBUG)
player = {'location': None, 'path': []}
cells = [(0, 0), (0, 1), (0, 2),
(1, 0), (1, 1), (1, 2),
(2, 0), (2, 1), (2, 2)]
def get_locations():
monster = random.choice(cells)
door = random.choice(cells)
start = random.choice(cells)
if monster == door or monster == start or door == start:
monster, door, start = get_locations()
return monster, door, start
def get_moves(player):
moves = ['LEFT', 'RIGHT', 'UP', 'DOWN']
if player in [(0, 0), (1, 0), (2, 0)]:
moves.remove('LEFT')
if player in [(0, 0), (0, 1), (0, 2)]:
moves.remove('UP')
if player in [(0, 2), (1, 2), (2, 2)]:
moves.remove('RIGHT')
if player in [(2, 0), (2, 1), (2, 2)]:
moves.remove('DOWN')
return moves
def move_player(player, move):
x, y = player['location']
player['path'].append((x, y))
if move == 'LEFT':
player['location'] = x, y - 1
elif move == 'UP':
player['location'] = x - 1, y
elif move == 'RIGHT':
player['location'] = x, y + 1
elif move == 'DOWN':
player['location'] = x + 1, y
return player
def draw_map():
print(' _ _ _')
tile = '|{}'
for idx, cell in enumerate(cells):
if idx in [0, 1, 3, 4, 6, 7]:
if cell == player['location']:
print(tile.format('X'), end='')
elif cell in player['path']:
print(tile.format('.'), end='')
else:
print(tile.format('_'), end='')
else:
if cell == player['location']:
print(tile.format('X|'))
elif cell in player['path']:
print(tile.format('.|'))
else:
print(tile.format('_|'))
monster, door, player['location'] = get_locations()
logging.info('monster: {}; door: {}; player: {}'.format(
monster, door, player['location']))
while True:
moves = get_moves(player['location'])
print("Welcome to the dungeon!")
print("You're currently in room {}".format(player['location']))
draw_map()
print("\nYou can move {}".format(', '.join(moves)))
print("Enter QUIT to quit")
move = input("> ")
move = move.upper()
if move == 'QUIT':
break
if not move in moves:
print("\n** Walls are hard! Stop running into them! **\n")
continue
player = move_player(player, move)
if player['location'] == door:
print("\n** You escaped! **\n")
break
elif player['location'] == monster:
print("\n** You got eaten! **\n")
break
else:
continue

TL;DR: Logging works, your code is fine. Kenneth's code in video has a bug (bad if
comparison)
In the video code, there is a bug in the draw_map
function. The blocks of code under the if
and else
sections are not the same. The if
block uses:
if cell == player['location']:
the else
block uses:
if cell == player:
The latter comparison will always fail because cell
is a tuple
and player
is a dict
.
In copying the code, you used the correct comparison to player['location']
.
Post back if you have more questions. Good luck!!
