No Module Named 'Characters'

[Literally Mom]

Hey! So I'm having a blast going through the tutorials and getting a feel of this absolutely awesome engine, but I came upon an issue when trying the 'aggressive NPC' tutorial.

When I go into the rooms.py file and add this: 

# mygame/typeclasses/rooms.py

from evennia import utils
from characters import Character
from npc import Npc

    # ... inside your Room typeclass ...
    def at_object_receive(self, obj, source_location):
        if utils.inherits_from(obj, 'Npc'): # An NPC has entered
            pass
        else:
            if utils.inherits_from(obj, 'Character'): 
                # A PC has entered, NPC is caught above.
                # Cause the character to look around
                obj.execute_cmd('look')
                for item in self.contents:
                    if utils.inherits_from(item, 'Npc'): 
                        # An NPC is in the room
                        item.at_char_entered(obj)

I get an error: 

The characters module definitely exists. I've tried everything, but I just can't seem to figure it out. I'd love some help.. ALSO, maybe I'm missing something super simple, but could I get a rough explanation of how to construct a storage item? Like a box or a backpack or jug of water, whatever. I'm sure I'll figure it out pretty quick from there. I did make a couple simple objects with self.db attributes, but I feel like a container needs some sort of dictionary list or something? Somewhere to store the data of what is in there, and then edit it when the item is removed or emptied?

I think you just need to specify the full python module name for your import: 

from typeclasses.characters import Character

wrt container objects, every Object has a .contents field which is a list of stuff inside it. E.g., things inside a room, or stuff your character is carrying. So, a box/backpack/chest/whatever could just be an Object subclass with .contents representing the objects inside it. If the you don't want the container object itself to be pick-up-able, you can restrict who can lock get() access. The tutorial world in evennia/contrib/tutorial_world does this for a barrel object: https://github.com/evennia/evennia/blob/10a6685fdf56c25c3e175df6753506af12f40d11/evennia/contrib/tutorial_world/build.ev#L442

hth,

*restrict who can get it (pick it up) by locking get() access.

Try to change the import to:

from typeclasses import characters.Character

or it might me

from typeclasses.characters import Character

I forget which and I'm on mobile at the moment.


As far as storing items in things, all objects are containers, you just have to search that object for the object inside of it and use move_to.

I wrote an explanation for this to someone else in chat, so I'll just link you to that spot in the chat log.

It might also be that you've indented the line :

def at_object_receive (blah blah)
everything else

It should be in-line with the line above it :

from evennia import DefaultRoom

I'm no expert, but I know that it goes bananas if the indentations are wrong.
Good luck.
