Persistent Data for Multiple Playthroughs

[Taylor]

Essentially, I'm looking for a way to activate a "switch" (I'm using true/false statements) in the first playthrough of my game that will be effect the game the second time it is loaded and played from the main menu.

I want to add in a bonus ending that is only available after all other endings have been found.

I have seen it in practice in the game DeIz, so I know it's possible, I just haven't found any info on it.

Thanks in advance!

There are a lot of ways to do this,

Using true/false statements is one way of doing it,
you could also create a variable that would change its value depending on what ending you finished

There is no correct way of doing it.

Also by your statement it sounds like you have the solution so may i ask what it is exactly that you haven't figured out yet?

You can use persistent variables that remain when the game is closed.
At the end of an ending:

Code: Select all

$ persistent.ending_1 = True

when you want to check:

Code: Select all

if persistent.ending_1:
    jump bonus_content

or if you want to present it when every end has been played:

Code: Select all

if persistent.ending_1 and persistent.ending_2 and ...more endings...:
    jump bonus

That's the method I tried. I keep coming up with this error whenever it reaches the "If" line (114):

File "game\script.rpy", line 114, in script
File "game\script.rpy", line 114, in python
NameError: name 'end01' is not defined

Lines 114-115 are:

Code: Select all

    if end01:
        jump bonus_ending

I have "$ end01 = True" during one of the endings.

It seems like the problem is that once the game reaches the If statement, it has an error because 'end01' isn't defined yet. I can't pre-define it, because then it'd just reset every time a new game started. Is it necessary to name it 'persistent.ending'?

[Tsapas]

Yeah, persistent variables need to be declared as such. It should be

Code: Select all

    if persistent.end01:
        jump bonus_ending

and

Code: Select all

$ persistent.end01 = True

I just made the edit and everything seems to be working fine now. Thanks!
