How can I output the value of a variable used in a screen for loop, during an exception?

[henvu50]

My renpy project is throwing an error: An exception has occurred. There are two variables presented that might be the problem, but I have no way of seeing what the value of those variables are.

1) How can I output the value of these variables from the console, to the console, or to a text file, or anywhere it can be seen?
2) Is it possible to use Renpy.say within a screen? Then I can output the value of the variable before it throws an error?
3) Is there a tutorial on how to debug like a pro in Ren'py? For example, how to debug from the console? Something that every Ren'py developer cannot live without?

Not sure how helpful this would be in the long run, but you could certainly output a variable into a portion of the dialogue that happens just before the exception hits. Just enclose the variable name in square brackets within the flow of the text, eg.

Code: Select all

"The exception is about to hit! Variable 1 is currently [variable1name], variable 2 is currently [variable2name]. Click to see the error..."

Well, there are sort of two consoles, the Ren'Py one (Shift + 0) and a Python one that you can launch alongside your game (by doing Launcher > Preferences (Launcher Options) and tick the Console Output checkbox.
If that is ticked all Python print output ($ print("debug message") etc) will be shown in that console.
Note: This console is not for typing stuff in, it is just for outputting messages.
