Lemma Soft Forums

Hey folks - ages back I released a game, and in looking at it for a possible update, I was slammed by two bugs I had no idea how to fix, that never appeared in my own playthroughs.

#1 good ol "unsupported operand type(s) for +=: 'NoneType' and 'int'" (using the same scripting += I have dozens of times in the game with no issues

#2 dag-nasty "IOError: Couldn't find file '[NONSENSE]'" (and then CHAOS with rendering)

Looking through the clipboard output of each of these, I've no earthly idea what's causing them - my only advantage here is knowing how to trigger them. (And that ain't much)

I know the idea of helping sort through a codedump output is hardly exciting, but from what I can tell in searching for "unsupported operand" issues like this, there are solutions that seem easy, but a lot of posts like "NM I fixed it" or "do this" without showing HOW or WHY. If any kind soul is feeling up for helping me squash these bugs, I'm in your debt on the real!

Can you post the tracebacks?

I'm sorry, but an uncaught exception occurred.

That's the main one, I'll ferret out the other.

Have you asked them to download it again, maybe their download got corrupted, that's what this looks like to me.

Theme_glow doesn't exist in a released game by default. You can add the theme data back with:

Oh cool! Also, odd that popped up... I made this a while back but I don't recall it being that long since editions, but eyyyy I am ok with being wrong!

Whereabouts should I add that line?

Add it anywhere as long as it isn't indented or inside another block.

I'd suggest just dump it at the end of options.rpy or somewhere in there (don't forget to add a comment so you know what it does for future reference)

Weird - put it at the end of options and got this:

```
I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.

Whew, got another issue - good news is I managed to fix the previous ones, bad news is this jerk popped up again:

I'm sorry, but an uncaught exception occurred.

That doesn't look like an issue with Ren'Py. What is line 1118 of endings.rpy? Are the variables there set all the time?

The "persistent.end_any +=1" is the line what offends. But that's kind of bonkers because 1) that kind of behavior happens EVERYWHERE and 2) it doesn't break in the slightest when running it in RenPy, only in the resulting build.

So, the problem is on a new game, the persistent file is empty. When you do:
it's None, so you can't add to it. You could repeat the problem locally by using the launcher to delete persistent.

What you probably want is a line:
To initialize it to 0, which should fix things.

AHA! That would make a difference for real... I thought the persistents didn't need to be initialized in the same way.
I have a file that loads all the triggers at the start, I imagine I should hit up the "default persistent.end_any = 0" then, and it wouldn't rewrite it on each restart...?

OK. Yeesh this has become a saga.

I have the "define build.include_old_themes = True" in screens. I have my 000_variables file properly dropping the "default persistent(blah) = False" to round things off.

Now I have this fun fun fun error when I try to start:
The offending chunk of lines in screens.rpy:
