Ren'Py Questions

The secret (and by that, I mean it's poorly documented) to fading into the main menu is to use the renpy.transition() function. This function will cause a transition to occur during the next interaction, regardless of what causes that interaction. So if you do something like:

Code: Select all

label main_menu:
    $ renpy.transition(dissolve)
 
    jump _library_main_menu

The dissolve will occur during the next interaction, which occurs during the _library_main_menu code.

Cool Didn't know that ^^

About music/sound : yes, you can use any format supported by Ren'Py. I think you could even use MOD files for sound effects, if needed .

Unfortunately, I used this code verbatim and it crashes the game with the error

Code: Select all

JumpOutException: start

The last script statement executed was on line 65 of common/mainmenu.rpy.

The traceback is nice and long and lovely, but it ends with something about ui.rpy having an exception with jumpsoutofcontext. I didn't want to tinker around with mainmenu.rpy and figure out what was causing it, so I decided to report it. (I'm on a Mac OS X 10.4.3 PPC G4, if it helps. Maybe it's just me...)

However, the same function can be used to do the same thing if it's called a the end of the splashscreen label:

Code: Select all

label splashscreen:
    ...
    $ renpy.transition(dissolve)

It's a nice effect. It's a shame that it doesn't work going out of the menu, though...

I just tried the same code

Code: Select all

label main_menu:
    $ renpy.transition(dissolve)
 
    jump _library_main_menu 

...in the demo on my linux workstation, and it doesn't crash, although neither does it provide the intended fade-in effect when starting the game, only when jumping to the main menu from the game menu, or at the end of the game.

The traceback is nice and long and lovely, but it ends with something about ui.rpy having an exception with jumpsoutofcontext.

It's also chock-full of information that helps me debug the problem.

If you could send me the traceback, and perhaps a game script that demonstrates the problem, I'd appreciate it.

Re: dissolving in the menu, and why it isn't happening for shaja... I think it may be because it's the first screen of the game, and we've never set anything to dissolve from:

Try something like:

Code: Select all

label main_menu:
    with None
    $ renpy.transition(dissolve)
 
    jump _library_main_menu

And see if that makes it work.

[shaja]

Code: Select all

label main_menu:
    with None
    $ renpy.transition(dissolve)
 
    jump _library_main_menu

Works as intended.

It stands to reason this 13 year old thread would have out-of-date information in it, but I can't get the most recent code example listed immediately above to work.

When I try this:

Code: Select all

label quitToMenu:

    pause

    $ quick_menu = False

    with None
    $ renpy.transition(pixellate)
    jump _library_main_menu

...this results in the below exception, I'm assuming because _library_main_menu is no longer what the main menu screen is referred to as.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 198, in script
    jump _library_main_menu
ScriptError: could not find label '_library_main_menu'.

Full traceback:

And when I try this:

Code: Select all

label quitToMenu:

    pause

    $ quick_menu = False

    with None
    $ renpy.transition(pixellate)
    return

...nothing happens, the game just immediately cuts to the main menu.

[duck-and-wolf]

Also, these do the exact same as using return (meaning, nothing at all, the game does return to the main menu but without any sort of transition):

Code: Select all

label quitToMenu:

    pause

    $ quick_menu = False

    with None
    $ renpy.transition(pixellate)
    $ MainMenu(confirm=False)()

Code: Select all

label quitToMenu:

    pause

    $ quick_menu = False

    with None
    $ renpy.transition(pixellate)
    $ renpy.full_restart()

I have re-asked this question in its own thread here: viewtopic.php?f=8&t=56907
