Ren'Py Where Is Ren’Py Rollback Length Defined?

[Monstrous Moonshine]

I've been trying to increase the rollback length but I cannot find the file within which the variables are supposedly defined. I was under the impression it was defined in options.rpy (which I cannot find at all), has this been changed in recent versions?

config.py, but I wouldn't edit it from there. It's better to edit it from within your project, along the rest of the config settings.

Hmm, I guess that he was more interested by "in what variable"

And the answer is

You must be registered to see the links

Alas, that did not work. Thank you though, kind stranger.

My bad, I am still sleepy so I answered the question literally x) also misread, and was under the impression that he knew already, but didn't find it anymore.

It should be both:
config.rollback_length
config.hard_rollback_limit

Both accepting an int as value, I wouldn't set it higher than 50, which shouldn't be too different from the default of 40 if I recall correctly.
The more you increase this value, the bigger save files will get.

I'm guessing the required data has been "trimmed", if I'm reading this correctly? Sad.

It works, changing the config.hard_rollback_limit really and effectively change the rollback length.
And I'm not saying "it's what the doc say", but "it's what happened when I tried right after you wrote your message".
Assumed that you don't go further than the 128 that is the full maximal length (see below).

It should be both:
config.rollback_length
config.hard_rollback_limit

Yes and no.
config.rollback_length is more specific, and generally larger than config.hard_rollback_limit. It's use to limit the size of the rollback stack, more than the number of step you can rollback too ; but well, also a yes since its value need to be at least equal to config.hard_rollback_limit.

[...] I wouldn't set it higher than 50, which shouldn't be too different from the default of 40 if I recall correctly.

It's been a long time (at least the version 7.0.0) that the default value have been passed to 100 (and 128 for rollback_length).

Oh wow, can't say I agree with that change. 100 is a lot.
Normally you'd be using rollback as a convenient way to undo a mistake if you forgot to save during a choice, or didn't think it was meaningful, so around 50 rollbacks are more than enough for that.
For all the rest there's a log system, so I can't imagine why anyone would want more than around 50, let alone more than 100.

Totally agree with you.

[...] so around 50 rollbacks are more than enough for that.

The default was 30 for a long time, and there's still many games that still have it even while using now a 7.5.x or 8.x version, because they started before the change. And honestly I rarely felt limited by that.
I mean, if you need more than 30 steps to understand that it's not the choice you wanted to pick, then the game isn't good enough and personally I don't play it.
