"$ sin_points += 1" not working

[Rinzamakani]

Hello. Lately, I've tried to add a sin or kill meter to my game. But when I defined it, I got this error:

Code: Select all

[code]
I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/killshadow.rpy", line 4, in script
    $ sin_points += 1
  File "game/killshadow.rpy", line 4, in <module>
    $ sin_points += 1
NameError: name 'sin_points' is not defined

-- Full Traceback ------------------------------------------------------------

Full traceback:
  File "game/killshadow.rpy", line 4, in script
    $ sin_points += 1

However, a person who checked my script said that everything was fine.
here's the code I used in my files:

In Script.rpy...

Code: Select all

default sin_points = 0

**This is above the label start**

And in the part where it's supposed to change the value within the story, after the label start:

Code: Select all

label killshadow:
   stop music fadeout 1.0
   play music "underwater.mp3"
   $ sin_points += 1

This works for a character of mine but I'm not sure why it isn't working for this. I even tried to define "sin" as a character but no luck.

It appears that you are doing things correctly...
As such I can only guess that perhaps persistent data (especially if running from a previous save) might be the cause. Does it still glitch if you delete persistent and start from the start?

That seemed to be the problem. Since I was playing the game from a previous save file that didn't have the code. Thanks.

The problem has to be with something you aren't showing in your code examples. A good way to deal with an issue is to try to isolate the problem entirely to determine if your core code is working. Then you can steadily eliminate possibilities. Try creating a new project with the entire script as follows:

Code: Select all

default sin_points = 0

label start:

    $ sin_points += 1
    "Sin Points = [sin_points]"
    jump start


    return

If you put this in a new project of your own and run it, you can verify that your sin_points are incrementing correctly. Thus, you know that the problem isn't in the syntax for the sin_points itself.

Without seeing more of your code, it is unclear why you are getting your error. However, the "+=" is triggering an error because python is looking for an existing variable of that name to which to add 1. That variable must already exist and be 'visible' to python at this location in the script. That means your original declaration is *not* visible for some reason...

If you post more code, perhaps someone will spot why your original declaration is not working.

LOL. I posted right after you... disregard!
