[Solved] Preview of latest save

[JungTaco]

On the main menu I want to show an image that represents a preview of the chapter where the game was last saved (but not a screenshot like in the save slots). I’m not sure how to do this.
I started something, but it doesn’t seem like a proper solution.

I save the current label in a json whenever the game is saved

Code: Select all

def label_callback(name, abnormal):
    if name.startswith("_"): return
        store.current_label = name
config.label_callback = label_callback

def save_chapter_name(d):
    d["chapter"] = current_label
config.save_json_callbacks.append(save_chapter_name)

I take the name of the newest slot and use it to get the label name from the json

Code: Select all

def newest_slot_tuple():
    newest = renpy.newest_slot()
    if newest is not None:
        page, name = newest.split("-")
        return (page, name)

def last_chapter_saved():
        newest_page, newest_name = newest_slot_tuple()
        return FileJson(newest_name, "chapter")

Depending on what the label is, I decide what chapter the game was saved at last

Code: Select all

def continue_image_button():
    if last_chapter_saved() == "chapter1" or last_chapter_saved() == "ch1_story":
        ...

But I'd have to check for every label in a chapter in order to do this and it doesn't seem like a good solution. Unless there's a way to automatically add all those labels in a list for each chapter.

Well, if this is just about some chapter preview image, it's really simple.

Whenever the game starts entering the new chapter, just save the current chapter inside a variable. In the main menu just read out this variable and show the preview image. You could even name the images according to the string you save.

Code: Select all

default last_chapter = None

label start:
   call chapter_one
   call chapter_two
   return

label chapter_one:
   $ last_chapter = "chapter1"
   ...
   return

label chapter_two:
   $ last_chapter = "chapter2"
   ...
   return

screen preview:
   if last_chapter is not None:
      # images should be named "chapter1.jpg" or "chapter2.png" etc.
      add "[last_chapter]"

I tried it and the last_chapter variable is always None when I start the game.

But I saved the variable in a json instead of the current label and it worked, so thanks anyway!
