DSE Error

[Nemo009]

Hey, total newbie question which, I'm sure, has an easy answer.

I tried using the stat system from the DSE as an add-on the visual novel I'm creating. I defined the stats (Intelligence and Charm) and launched the game. But when it came time to display the stats, the game crashed and I got this traceback:

Note: I've abbreviated the file locations for privacy, but the full line is completely necessary, I'll post it.

Code: Select all

I'm sorry, but an exception occured while executing your Ren'Py
script.

AttributeError: 'module' object has no attribute 'charm'

The lines of code in the game was just:

Code: Select all

$ display_stats()

For easy reference, here are the lines of code (apparently) being referenced (Taken from the stats):

Code: Select all

def normalize_stats():
        for s in __dse_stats:

            v = getattr(store, s.var)

            if v > s.max:
                v = s.max
            if v < 0:
                v = 0

            setattr(store, s.var, v)


    def display_stats(name=True, bar=True, value=True, max=True):

       [b] normalize_stats()[/b]
        
        ui.window(style=style.stats_frame)
        ui.vbox(style=style.stats_vbox)
            
        layout.label("Statistics", "stats")
        
        for s in __dse_stats:
            [b]v = getattr(store, s.var)[/b]

            ui.side(['l', 'r', 'c'], style=style.stat_side)

            if name:
                layout.label(s.name, "stat")
            else:
                ui.nul()

            if value and max:
                layout.label("%d/%d" % (v, s.max), "stat_value")
            elif value:
                layout.label("%d" % (v,), "stat_value")
            elif max:
                layout.label("%d" % (max,), "stat_value")
            else:
                ui.null()

            if bar:
                ui.bar(s.max, v, style=style.stat_bar)
            else:
                ui.null()

            ui.close()
                
        ui.close()

If anyone here needs anything else, please let me know. And sorry if the answer is obvious - I'm really stumped and searching this forum didn't shed any light. Thanks!

Why are there tags around some of that code? Or is that just from jedit or something?
Um, could you post the bit where you define the charm stat?

[Nemo009]

Whoops, sorry about that! The tags were meant to highlight the lines of code listed in the traceback, (that is, line 39 and line 51), but I guess it failed. (Which is bizarre, since those lines appeared bold in the previews... oh well.)

Here is where I defined the stats. Sorry, I guess these WOULD be kind of important too.

These were taken directly from the script.rpy file at the very top.

Code: Select all

    init:
        # Declare images below this line, using the image statement.
        # eg. image eileen happy = "eileen_happy.png"
        image bg city = "city.jpg"
  
        # Declare characters used by this game.

        $ s = Character('Stephanie', color="#66ff99")
        $ c = Character('Chaos', color="#3366ff")
            
    init python:
        register_stat("Charm", "charm", 10, 100)
        register_stat("Intelligence", "intelligence", 10, 100)

    
    # The game starts here.
    label start:
        

Since I'm really inexperienced with Python (all I know are HTML and some entry-level C++), I wouldn't catch any but the most obvious errors. Sorry if the answer is clear and I'm just not seeing it.

[Showsni]

I'm not too savvy on Python, but I think that the "has no attribute" bit means that somewhere it's getting something like module.charm where the module object doensn't have anything defined for having a charm there. I don't know if the actual word module appears anywhere in your script, or if that's referring to something else or something... I guess you could look through your script for module and charm and see everywhere they occur. I don't think there's anything wrong with the code you've posted; hm, unless...

Ah, that might be the problem. The stat engine uses the letter s as a variable (or something); you're also using the letter s to refer to a character. See if changing that letter s referring to Stephanie (like, $ st = Character('Stephanie', color="#66ff99")) makes a difference.

You know, that was a good thought. I'd honestly never have thought of something like that... Oddly enough, though, it didn't work.

I took that 'stats.rpy' file from the dse Framework, since all I wanted were stats (as in, without the day planner aspect). However, I take it that at least one thing in that must need SOMETHING that I'm just not giving it. Do you (or does anyone else) have any advice?

[Nemo009]

...actually, you're not going to believe this, but it seems there was a big misunderstanding with file management. I had never thought of starting a NEW game save-file - I'd just been reloading from the part of the story where the game first displays the stat values. Of course it had crashed - that file hadn't had the stats defined yet. I started a new file and made my way back to that particular place; since the stats were now defined, that fixed everything!

Sorry for that. And thank you for all your help!
