Making a "Lock Save" action

[GreyWolfXx]

How could I make an action in the Load/Save menu so that players could lock a game state? Meaning that they can't delete it or overwrite these locked saves.

We can't do this - but it's a good idea. I'll look at what it will take to add something like this.

Oh really? Alright, thank you!

I did something like that with a persistent list variable (persistent.locked). I had an imagebutton that called one of two functions based on whether the save was locked or unlocked (unlockSave or lockSave) that either appended or removed the filename to persistent.locked. Then under the button actions for the save screen I had an if statement that would check to see if the filename was in persistent.locked. If it was, I'd have the action be nothing. Otherwise it'd do the FileSave() action. I actually have it a lot more complicated than that because I tried adding a bunch of additional features and also use an imagemap, but just for locking a save that seemed to work.

So in options.rpy I had:

Code: Select all

init -1 python hide:

    if persistent.locked is None:
        persistent.locked = []

the functions were thrown in a specific file I had for definitions, but it could be in any file I believe:

Code: Select all

init python:
            
    def lockSave(slotname):
        persistent.locked.append(slotname)
        if persistent.locked is None:
            persistent.locked = []
        
    def unlockSave(slotname):
        persistent.locked.remove(slotname)
        if persistent.locked is None:
            persistent.locked = []

(the "if persistent.locked is None: persistent.locked = []" parts for the functions were just because it was throwing weird errors and that seemed to fix it, your code may work without it)

Since the game I have locked saves for uses imagemap and the button code I'm getting from another game doesn't have locked saves, my code is much different than the default save/load code. So you might need to mess around with it for it to work, but maybe try

Code: Select all

screen file_picker():

    frame:
        style "file_picker_frame"

        has vbox

        # The buttons at the top allow the user to pick a
        # page of files.
        hbox:
            style_group "file_picker_nav"

            textbutton _("Previous"):
                action FilePagePrevious()

            textbutton _("Auto"):
                action FilePage("auto")

            textbutton _("Quick"):
                action FilePage("quick")

            for i in range(1, 9):
                textbutton str(i):
                    action FilePage(i)

            textbutton _("Next"):
                action FilePageNext()

        $ columns = 2
        $ rows = 5

        # Display a grid of file slots.
        grid columns rows:
            transpose True
            xfill True
            style_group "file_picker"

            # Display ten file slots, numbered 1 - 10.
            for i in range(1, columns * rows + 1):

                # Each file slot is a button.
                button:
                    $ file_name = FileSlotName(i, columns * rows)
                    $ file_time = FileTime(i, empty=_("Empty Slot."))
                    $ save_name = FileSaveName(i)
                    if(file_name in persistent.locked):
                        action None
                    else:
                        action FileAction(i)
                    xfill True

                    has hbox

                    # Add the screenshot.
                    add FileScreenshot(i)

                    text "[file_name]. [file_time!t]\n[save_name!t]"

                    if(file_name in persistent.locked):
                        if file_time != "Empty Slot.":
                            imagebutton:
                                idle "lock_close.png"
                                hover "lock_open.png"
                                action [Function(unlockSave, file_name)]
                    else:
                        if file_time != "Empty Slot":
                            imagebutton:
                                idle "lock_open.png"
                                hover "lock_close.png"
                                action [Function(lockSave, file_name)]

                    if(file_name not in persistent.locked):
                        key "K_DELETE" action [FileDelete(i)]

in whatever file you have the save/load screen code. Like I said, I kind of had to piece the two together so some of the code might be wrong. But that's the general gist of what I did to get locked saves to work for my game.

And here's what it looks like on mine*:

Save is unlocked and delete icon is clickable

and

Save is locked and delete icon unclickable

*Trashcan code not included

edit: also you might want to add a little blurb so it only makes the save button have no action when locked if it's on the save screen. Otherwise no one can load their locked saves. My code has the load and save screens as separate so I didn't have to figure out how to differentiate between the two, so I don't know how to help there.

Thanks, 15nick, this is really helpful! I think I'll be able to do it now . I'll post any further questions here.
