[SOLVED] Could not find return label

[Kinmoku]

Hello. I've run into an odd error. When I try and finish the game it comes up with this:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 2524, in script
    return
Exception: Could not find return label (.../Documents/Game/One Night Stand/game/script.rpy', 1458288718, 133).

Darwin-14.0.0-x86_64-i386-64bit
Ren'Py 6.99.9.1168
One Night Stand 0.0

and "return" is in the script. I've updated Renpy and deleted my cache/ persistant data. Any ideas?

You've messed up the return stack somehow. No way of knowing how without seeing the whole code, but the chances are that it's your fault

Ah ha, I was afraid of that! What's the easiest way for me to check where I've gone wrong? I've looked over the code briefly and it seems ok to me.

I can only imagine how this happens... you could have messed up the stack by implicitly interfering with it or doing something insane like going out of the games context for no reason (although return should then plainly return you back to games context). I cannot come up with a simple way to do it while following the general coding guidelines for Ren'Py. Last index on call stack returns None for you, I don't know why If I were to try and replicate this, creating a save file while in a called label and then delete the label where the call originated would be a (reasonable) place to start, but you never said anything about loading a save and I am not 100% sure that it'll cause the error to occur.

As I've said, the chances are that you may not even get this error outside of dev mode. If you figure out what it is, please let me know, I'd like to know how that can happen without explicit interference (which I am fairly certain you didn't do, cause it's neither easy, nor is it something you'd randomly do).

Ok, this is so weird. It's stopped doing it now! I swear I haven't changed any of the calls, jumps, returns or updated or anything! That's so weird... But at least it's fixed!

I mostly get that error when I delete the label/a bigger portion of the text where I'm in the game when it automatically reloads.
restarting from main menu/somewhere that still exists is the easiest fix I guess.
Shouldn't happen in a finished game ^^

Ah nice! That explains why it seemed to just fix itself Thanks!

This is a bit technical, but it can help with understanding basic stack principles: http://www.cs.umd.edu/class/sum2003/cms ... stack.html

TL;DR you probably accessed something outside of the part of the code you were in. When calling a function, only globals (that have already been initialized) and stuff from within the function you called works, generally speaking. Editing live code will often bork that up.

Glad it's straightened out.
