Character speaks based on a variable?

[wyverngem]

Question:
Can I make a character have dialogue based on a variable? Such as a True or False or even if they are in a list of names?

For example you have a party made up of different people. You have your main character and they can bring two people with them out of five in the game. I don't want to spend my time coding "if BenInParty" or "if 'Ben' in party_list" show dialogue. Could I put it in there defined character instead?

For example it would look like this.
"You bring Ben and Joe with you. You left Tony, Chris, and Ella behind at camp."

Code would be:

Code: Select all

MC "Is he seriously still on his monologue?"
b "I know right?"
t "Ugh, how much longer will this take?"
j "I don't like what he's saying about us, [mc_name]."
e "Ooh, ooh my nails are dry. Let the guy talk more!"

In-game it would appear (If you had Ben and Joe):

MC "I-I think he's still monologuing."
b "I know right?"
j "I don't like what he's saying about us, Alice."

I'm not sure if I'm putting it in the wrong place or if it's just not possible with an error I always get with Python and screen about a Revertable List.

I tried writing a condition, but I don't think I'm doing it right. The error is below. I'm simply trying to add a condition to the Character Object and using python to check if the person is in the party.

Code: Select all

define party_list = []

init python:
    global party_list
    def inparty(name):
        if name in party_list:
            return True
        else:
            return False

    def add_member(name):
        if name not in party_list:
            party_list.append(name)

    def remove_member(name):
        if name in party_list:
            party_list.remove(name)

define j = Character("James")
define k = Character("Karen", condition=(inparty('Karen')))

label start:
    $ party_list = []
    if inparty('James'):
        j "I'm here."
    else:
        $ party_list.append("James")
        j "Hold up, I'm coming!"
    "Thanks for showing up James."
    j "Not a problem."
    k "You can't see me."
    "I'm testing if I can see if there are people in a party."
    j "Well, let's get going."
    return

Code: Select all

I'm sorry, but an uncaught exception occurred.

I haven't tested it, but the error message itself is telling you that the condition needs to be a string.

Code: Select all

define k = Character("Karen", condition=("inparty('Karen')"))

What is a "code object"? I wrote it as a string and it worked fine. Thank you.

A code object is a python entity compiled in CPython to be further processed (like a kind of "intermediary" translation). Something we never touch on renpy use.
