how do you use persistent data? (solved)

[BreathingColors]

Code: Select all

label start:
    
    $ persistent.gasterend = 0
    $ persistent.Freshend = None
    $ persistent.killerend = None
    
    if persistent.gasterend == True:
        menu:
            "Reset":
                $ persistent.Freshend = False
                $ persistent.killerend = False
                return
            "return":
                return
    else:
        jump start_2
        
    
label start_2:
    scene bg room
    show GF 1

    GF"Hello, world."
    show GF 2
    GF"You've created a new Ren'Py game."
    GF"Once you add a story, pictures, and music, you can release it to the world!"
    
    if persistent.freshend == True and persistent.killerend == True:
        jump c
    else:
        jump b
label b:
    menu:
        "fresh end":
            $ persistent.freshend = True
            $ renpy.save_persistent()
            jump freshending
        "killer end":
            $ persistent.killerend = True
            $ renpy.save_persistent()
            jump freshending
label c:
    menu:
        "gaster end":
            $ persistent.gasterend += 1
            $ renpy.save_persistent()
            if persistent.gasterend == 1:
                jump gasterending
            if persistent.gasterend > 1
                jump gasterending2
        "fresh end":
            $ persistent.freshend = True
            jump freshending
        "killer end":
            $ persistent.killerend = True
            jump freshending
            
label gasterending:
    "gaster end"
    return
label gasterending2:
    "gaster end2"
    return
label freshending:
    "fresh/killer end"
    return 

So what I'm trying to do is once you get all the endings you have the option to choose gasters end, once you get gasters end you can do a restart except for gaster, gasters ending cannot be reset

I recommend against it being a once view only route, no reset, but anyway:

Code: Select all

# Define all variables before the start label with default

default persistent.gasterend = 0
default persistent.Freshend = None
default persistent.killerend = None

label start:

The rest of your code is too difficult to read on a mobile device.

Also, use code not c when pasting your code.
c is for one liners

Please note, while regular variables are divines using default, persistent variables are declared using define.

So:

Code: Select all

# Define all variables before the start label with default

define persistent.gasterend = 0
define persistent.Freshend = None
define persistent.killerend = None

label start:

Woops, did I write default? Guess I did.
Another case of just-woke-up -I-shouldn't-be-on-the-computer.

[PyTom]

Persistents work the same way with default and define, so both are correct. I think "default" is probably the better one to use, since it's semantically closer to what's happening.

[trooper6]

Thanks for the info PyTom, the Changelog seemed to imply that persistent variables should use define...knowing that I can use default for everything makes my life easier. The difference between default and define isn't very clearly articulated in the documentation.

[PyTom]

It's possible it's an older changelog. Define came first, and default second.

Generally, nowadays, if something can change, use default. If something can't (a character or constant), use define. In fact, changing something that's been defined can lead to problems, as Ren'Py is willing to optimize variables set using define.
