I've been working on a text-based RPG for a while now on-and-off. After a long hiatus, I've come back to the project.

My goal as of right now is to port the game from it's current Print-output version to a version that works in a Pygame window before I add anything else.

Now it's worth mentioning that I'm a complete noob to programming. This is my first project. I'm still pretty uncertain on the proper ways of separating logic/general code architecture.

This being said, here is my code.

Game File (FlubbosMagicForest.py):

from gameworld import *

def main():

 player = Player("Jeff", 100)
 bag = Bag()
 location = Location('introd')

 command = ' '
 while command != "":
 command = input('>>> ')
 if command in location.room.exits:
 location.travel(command, bag)
 elif command == 'look':
 location.room_desc()
 elif command == '':
 print('You have to say what it is you want to do!')
 command = '#'
 elif command == 'search':
 location.search_room()
 elif command.split()[0] == 'Take':
 location.check_take(command.split()[1], bag, location)
 elif command == 'Inventory':
 bag.check_inv()
 else:
 print('Invalid command')


if __name__ == '__main__':
 main()

gameworld.py:

from gameitems import *

 def __init__(self, name, description, exits, actions, roominv, roomkey, lock):

Please let me know if anything is blaringly wrong, I'm sure there is. If anyone has any tips on restructuring the code to prepare it for a Pygame adaptation, that would be much appreciated.

main program:

while command != "":

could be

while command:

but you have to initialize command to non-empty. I'd do:

while True:

then at the end:

 if not command:
 break

gameworld.py:

in Locations.travel, don't use in xxx.keys(). It doesn't matter much in python 3, but python 2 makes that a list, whereas the simplest & universal way is:

if direction not in self.room.exits: # no .keys(), dicts support "in"

In Locations.check_take, don't check if the dict is empty, it's cumbersome:

if self.room.roominv and key in self.room.roominv:

should just be:

if key in self.room.roominv:

In Locations.check_inv:

for item in list(self.inventory):

why forcing iteration on self.inventory? Just do:

for item in self.inventory:

I'd like to add that your initialization of world is clumsy & error prone. You should loop on the items of a dictionary/list of dictionaries contained in a json configuration file instead, so anyone (even not a python coder) can improve the game map.

world['introd'] = Room('introd', "You are in a forest, you can hear wildlife all around you. There seems to be a clearing in the distance.", 'n': "clearing", "Search the ground", "Go North", 'Sword': Sword, None, False)

(and the other entries) could be loaded from a dict containing the key (introd), the description, and the dictionary of directions & contents. This is more complex because you're using an object like Sword as key (so you'd need some kind of evaluation/lookup table to create the object, not a big deal). Think about it.

gameitems.py:

not much, except that this code is redundant:

class DoorKeys(Items):
 def __init__(self, name, info, weight):
 super().__init__(name, info, weight)

could just be:

class DoorKeys(Items):
 pass

at this point, since you're not adding anything specific. So DoorKeys object is probably redundant as well unless you're planning to add specific stuff.

I feel like utilizing classes for some parts but disregarding them for others is throwing the entire thing off.

The massive if/elif/else block in the command file could easily be a list of predefined Command() instances, and a step further, referenced inside of a Commandlist() instance. It might take a little bit more time to code all of the class definitions, but everything would be stored more neatly, and would be easier to reference. As a side note, cmd2 works pretty well for all text-based, has an easy way to define commands, and could be used to test that things are functioning properly.

It would also be fairly easy, and far more organized, to define a World class with various attributes.

class World():
 def __init__(self, rooms, start_id = 1, num_of_rooms = 3):
 self.rooms = _rooms
 self.id = _id
 self.num_of_rooms = _num_of_rooms

You could easily add other attributes to World if needed, and it helps to set up for what @Jean mentioned, which is feeding in data from json files. Surprisingly easy to do, and while the files aren't the prettiest format, it's still much more appealing than scrolling through a wall of code to change a specific room's name because it was hardcoded into a file.

This opens up the possibility for using many other class instances to hold all of your data and storing them within a World() instance for easier access. All you would need is a method to load the data as a dictionary and unpack it to the arguments of an object instance. Note, I'm using pkg_resources with this, so you would need to import pkg_resources or just the specific re

def _build_room(self, id):
 jsontext = resource_string(__name__, 'data/dungeon/room.json'.format(self._id, id))
 d = json.loads(jsontext.decode('utf-8'))
 d['id'] = id
 room = R.Room(**d)
 return room

Of course you would also need a method which utilizes build_room() to create a dictionary of rooms for World.rooms, but that's as easy as...

def _update_rooms(self):
 d = 
 for i in range(self._start_id, self._num_of_rooms + 1):
 try:
 d[i] = self._build_room(i)
 except FileNotFoundError:
 print("File not found. Please check to make sure it exists")
 self._rooms = d

This same principle could be used to create a container for all items in a game, an inventory system, characters, and many other possibilities.

Note that I'm not advocating this as the best way, or even a good way. I'm still a beginner and there are many concepts I'm still fuzzy on. This is just the conclusion I reached from all of my various reading of things other people who seem to actually know what they're talking about have typed out. Also, I'm no help down the road towards GUI, and I have no idea if any of this would muddle an approach towards it or ease it.

I'm actually working on something very similar to this. If you're interested, you can find it all here.
