[Solved] Extras gallery button not defined

[Ayael]

Hello, I tried to follow, this EXCELLENT tutorial (viewtopic.php?f=51&t=50040&p=511085#p511085) to create my own CG gallery, but, even so I didn't touch a single line of the code he gives, I have this error :

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:

Error, I really doesn't understand, since the cg_gallery01 it is definitely define in the code :

Code: Select all

g = Gallery()
    g.button("cg_gallery01")
    g.image("image1")
    g.unlock("image1")

(Plus I was wandering how the "line 330" can have an error on it considering, there is only 290 lines in the code... )

As always, thank you very much for your help!

Could you please paste your code here onto the site? You said its from the tutorial, but specifically to find the issue in your code, we need to see your whole code to find out what the problem exactly is.

But i think the issue is the part you posted, it should be like this:

Code: Select all

init python:
    g = Gallery()
    g.button("cg_gallery01")
    g.image("image1")
    g.unlock("image1")

Anyways, first fix that and afterwards, if the problem still persists, paste your code. I hope that solves the issue though (:

Hi, thank you to look at my problem !
Sure, but as I said, I didn't change anything from it, so it must be the same than the file we can download.

Anyway, here it is :

Code: Select all

Hmm thats weird, it should recognize it. Can you try deleting your persistent data maybe?

EDIT: Also, did you copy/paste it into your screen.rpy at the end or where in your files is that part? Nvm, i just cant read xD

Thank you again for your help !

I try to remove all persistent data from my game (script + extras) it didn't change anything.

BUT, I noticed, when I try to reload the game, I have this error, maybe it's linked ?

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "renpy/common/00start.rpy", line 203, in script call
    call _load_reload_game from _call__load_reload_game_1

Exception: Couldn't find a place to stop rolling back. Perhaps the script changed in an incompatible way?

I think that error appears when you reload the game when it open and the script changes in a way not able to roll back. Usually re-opening help!

Another thing you could try is copy/paste the whole code from the rpy file into the screens.rpy (at the very end) and to declare the images used in the gallery. Did you do that?
Example:

Code: Select all

image image1 = "images/image1.png"
image image2 = "images/image2.png"
## and so on

init python:    
    g = Gallery()
    g.button("cg_gallery01")
    g.image("image1")
    g.unlock("image1")

I FOUND THE PROBLEM. I did many try with gallery earlier, and there is one other files I didn't delete on the game folder with gallery statement. I tried to remove it, and suddenly, it worked perfectly ! (Sometimes there is really stupid thing that bother us)

Thank you, your last saying enlighted me !
