Ren'Py won't recognize array index variable as integer

[Ayutac]

First off I'm sorry if this problem is easy to find with the search because it won't really work with me. (Fixing in progress.)

But now to the problem: The error looks like this:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/girlNavData.rpy", line 118, in script

The code fragment is the following:

Code: Select all

init python:
    [...]
    girlsname = ["Misty", "Saphire", "Cynthia"]
    girlsnameS = [ # the genitive
        "'s", ## Misty
        "'s", ## Saphire
        "'s"] ## Cynthia
[...]
label meetMisty:
    $ girl = 0
    show misty normal at right
    jump meetGirl
[...]
label meetGirl:
    if girllist[girl].hasChanged() == True:
        "Congratulation, now you are [girlsname[girl]][girlnameS[girl]] [girllist[girl].MilestoneName]!"
    menu:
        "HP: [prota.HealthPoints]\nRelation: [girllist[girl].MilestoneName]\nExperience: [girllist[girl].Exp]"
        
        "speak":
            jump speakGirl
        [...]

girllist is a array with (self-created) girl-objects in it. The line in question is line 118, which is the line with "menu:". I strongly believe the error comes from the line after it, since it didn't appear after I removed the array-properties and since the choice in line 116 returns False for the moment, so line 117 is not entered.

I solved the problem by doing a trick literally just now:

Code: Select all

label meetGirl:
    $ GIQ = girllist[girl] ## short for "girl in question"
    $ GNIQ = girlsname[girl] + girlsnameS[girl] ## short for "girl's name in question"
    if girllist[girl].hasChanged() == True:
        "Congratulation, now you are [GNIQ] [GIQ.MilestoneName]!"
    menu:
        "HP: [prota.HealthPoints]\nRelation: [GIQ.MilestoneName]\nExperience: [GIQ.Exp]"

But I would really like to know what went wrong before. It seems the Character's say-Statement can't really use array properties or what?

I just toyed with some code and I hopefully can shed some light on your question. In the line of code:

Code: Select all

"HP: [prota.HealthPoints]\nRelation: [girllist[girl].MilestoneName]\nExperience: [girllist[girl].Exp]"

You are trying to display 'girllist[girl].MilestoneName'. The code has an error because the index is not looked at as a variable that results in its contained value. If you edit this line of code with hard values such as:

Code: Select all

"HP: [prota.HealthPoints]\nRelation: [girllist[0].MilestoneName]\nExperience: [girllist[0].Exp]"

Then you shouldn't get an error. I understand how this isn't desirable and the fix you posted solves this probably by avoiding using a variable index within the say statement.

Another possibility that came to mind is to use python's .format() function by turning your statement into a python statement. For example:

Code: Select all

   $ narrator("HP: {0}\nRelation: {1}\nExperience: {2}".format(prota.HealthPoints, girllist[girl].MilestoneName, girllist[girl].Exp))

The above code doesn't look all that pretty, but it should also work!

Ah, this should work just fine. I thought about how to insert the whole stuff into the string in Python but didn't thought it had to have a format function. So, thank you very much. I would be still curious how it would work in Ren'Py mode :D
