screen action Show() choosing one from a list of screens?

[searchwindows]

I'd be thankful if someone could lead me in the right direction with this.

I have a clickable phone display; screen phone_home: with an imagebutton "change_phone_bg".

I'd like to be able to click on that imagebutton to change the background image of the phone from a list of let's say, 5 background images. [bg1,bg2,bg3,bg4,bg5]

I also need the chosen bg to stay as the bg on all phone screens, like on phone_settings screen and phone_messages screen. Then if I were to change the bg again, I need the change to be implemented to other phone screens as well.

This is how I have it set up:

Code: Select all

1 screen phone_home:
2	add "bg0"    ### So I need this line to change to bg1,bg2,bg3,bg4 or bg5 when I change the bg with imagebutton on line 12.

4	imagebutton auto "images/phone/message_icon.png":
5	focus_mask True 
6	action Show("message")
7	
8	imagebutton auto "images/phone/settings_icon.png":
9	focus_mask True 
10	action Show("settings")
11
12	imagebutton auto "images/phone/change_phone_bg.png":
13	focus_mask True
14	action(?????) ## How to make it so that bg1~bg5 is shown one by one so the player can choose.

define backgrounds = ["bg0", "bg1", "bg2", "bg3", "bg4", "bg5"]
default bg_index = 0

init python:
    def next_background:
        store.bg_index += 1
        if store.bg_index == len(store.backgrounds):
            store.bg_index = 0

screen phone_home():
    add backgrounds[bg_index]

    imagematton auto "..." action Function(next_background)

screen phone_home():
    add backgrounds[bg_index]

    imagematton auto "..." action Function(next_background)

thank you! But I'm getting invalid syntax error on

Code: Select all

def next_background:

Oh, my bad, it should be def next_background():

Thank you!
Everything works as intended but the bg image resets back to bg0 after saving and loading back.
How can I make it stay the one you've chosen?

It should not do that. Did you make any changes to code? Especially notice that both define and default are used.

The only changes I made are the name of the variables to my liking.

This is what I have:

Code: Select all

screen phone_home():
    modal True
    add phone_bgs[bg_index]
    ##Settings button
    imagebutton auto "images/phone/settings_%s.png":
         focus_mask True
         action [Show("phone_settings"), Hide("phone_home")]
         
define phone_bgs = ["bg0","sbg1", "sbg2", "ebg1", "ebg2", "kbg1"]
default bg_index = 0
init python:
    def next_bg():
        store.bg_index += 1
        if store.bg_index == len(store.phone_bgs):
            store.bg_index = 0

screen phone_settings():
    add phone_bgs[bg_index]
	## button for bg change
    imagebutton auto "images/phone/settings_bgchoose_%s.png":
        focus_mask True
        action Function(next_bg)
        ##button to return back to phone home screen. 
    imagebutton auto "images/phone/return1_%s.png":
         focus_mask True
         action [Show("phone_home"), Hide("phone_settings")]

So, what are you doing exactly?

My assumption is that you open your phone, click "next background" several times, immideately save then load.
In that case the problem you have is that RenPy saves state on checkpoints. For example, if you were to close your phone screen and advance dialogue, then it will save, since you hit a checkpoint.
Depending on how your game is structured, you might need to use retain_after_load or checkpoint

You're right. It saved after a dialogue. I think that's plenty enough. Thanks as always
