Ren'Py [Need Help with findinding mistakes and possible sollutions]

[Cyber_V]

Hey guys I am making a game for the first time in ren'py and facing this error when I am defining a new nvl character for the phone chat, I did not face any issues uptil adding mc and two characters:

I'm sorry, but an uncaught exception occurred.

While running game code:

background Frame(message_frame, 23,23,23,23)

Well, like the error message

You must be registered to see the links

, there's no variable, or due to the context, no defined image, named "message_frame"...

Create the variable, with its expected value, or define the image, depending on what you intended to do, and the problem will be solved.

When looking at the Renpy exception messages, you need to understand that the actual error string is at the end of the backtrace.

in this case: NameError: name 'message_frame' is not defined

The start filename/line number of the trace can help you track down where the error is being triggered.
The in-between lines of the trace are not very often helpful, as they often descend into the Renpy internals
The end filename/line number of the trace can help you track down where the error is located.

Unfortunately there are no shortcuts; only experience, understanding and logical thinking will help you find the cause of exceptions.
