Help me fix my game, please!

OK this is my Dungeon game, I wish I can do it by myself but it took me a week and also still not done yet, so I think I need help! The plan is after a certain move, a new monster will appear, so you have to find the door quickly before you get stuck. The problem with my game is after a new monster appears, they didn't move! The only one keeps moving is the first one. So anyone here can help me? I also hope Kenneth Love can teach me more about this game :grin:

Can you describe the bug you are seeing? Some items I noticed:

  • "A" is moving Left, "D" is moving right. This differs from directions
  • On my screen, the map characters are wider for the icons vs the grid. I added a temp space to the grid to fix the spacing.
  • Some functions return values, but the calling statement makes no use of the return value.
  • valid_monster_moves assigned by not used
  • in get_moves_player use if and not elif because if in a corner, only one of the two into-a-wall moves is removed.
  • as monster moves, the old position of the monster doesn't seem to get removed from the monster locations

Hope these help as a start. Good luck!

Thanks for the answer, Sir. My problem is when a new monster appears, it just stands still, only first monster keep moving. And when I play for a while, the first one disappears! I've tested many time but still didn't find the error. Anyway, your answer helps me a lot :smiley:

I found two additional errors.

  • It looks like the return statement in monster_location_update(), line 319, is indented too far making the update loop stop after the first monster.
  • In monster_moves_update(), the global ALL_VALID_MONSTER_MOVES gets new monster moves appended but the old moves are not removed. This makes the list grow very long, but only the unchanging moves at the beginning of the list are repeatedly used. Try adding the line:
    ALL_VALID_MONSTER_MOVES = []

I've fixed and tested these things alone. The monster_moves_update seems like doesn't work. I expect the ALL_VALID_MONSTER_MOVES will change after the function is called, but it doesn't, although ALL_MONSTERS was changed. Is there something I've done wrong Sir?

It seems to be working ok. I added a few more print statements and got the following result:

print(ALL_MONSTERS)
print(monster_moves_update(custom_cells))
print(monsters_location_update())
print(monster_moves_update(custom_cells))
print(monsters_location_update())
print(monster_moves_update(custom_cells))
print(monsters_location_update())
