Changing ShowMenu transitions for certain screens

[Arowana]

Hey, all! I was wondering if there is any way to switch the transitions used by ShowMenu for specific screens.

As far as I can tell, the transitions used by ShowMenu are controlled by config.enter_transition and config.exit_transition, so any screens called by ShowMenu can only be shown with the same "default" transitions (in my case, "fade"). But I want certain screens to have different transitions (e.g. "None") when they are shown/replaced.

I tried switching the default transition with [SetField(config,"enter_transition", None), SetField(config,"exit_transition", None)] when I enter the screen, then resetting the default transition with [SetField(config,"enter_transition", fade), SetField(config,"exit_transition", fade)] when I exit the screen. Resetting the exit transition while leaving the screen, however, causes the screen to exit with "fade," rather than "None" as I want. Not sure how I get around this. Surely there must be a better way to switch the transitions for a particular screen?

Take a look at 00screens.rpy. You should figure out how to do this.
Hint: compare Show(action) and ShowMenu(action).

Cool, thanks for the tip - I managed to get it working the way I want, e.g. I can now use ShowMenu(“myscreen”, transition = fade) to have “myscreen” appear/exit with the fade transition rather than the default. I’ll record my solution here in case anyone else is interested. It requires modification of both 00screen.rpy and 00library.rpy.

In 00screen.rpy, modify several lines of the ShowMenu class:

Code: Select all

class ShowMenu(Action):
    def __init__(self, screen=None, transition=None):
        self.screen = screen
        self.transition = transition
         (…)
        else: # if not in game menu (e.g. showing screen from game)
            renpy.call_in_new_context("_game_menu", _game_menu_screen=screen, transition=self.transition)
         (…)

In 00library, modify the contents of the “_game_menu” label to use the transition given by ShowMenu, instead of the default enter and exit transitions:

Code: Select all

# Entry points from the game into menu-space.
label _game_menu(_game_menu_screen=_game_menu_screen, transition=None):
    if not _game_menu_screen:
        return
    
    call _enter_game_menu(transition) from _call__enter_game_menu_0  # use the transition when entering game menu
    
    if renpy.has_label("game_menu"):
        jump expression "game_menu"

    if renpy.has_screen(_game_menu_screen): # this is the part we’re interested in, because we’re using ShowMenu on a screen
        $ renpy.show_screen(_game_menu_screen)
        $ ui.interact()
        
        if transition is not None: # if we have a transition we want to use
            #copy of _noisy_return (not sure how to pass arguments to jump ^^;)
            $ renpy.play(config.exit_sound)
            
            #copy of _return
            if renpy.context()._main_menu:
                $ renpy.transition(config.game_main_transition)
                jump _main_menu_screen

            if transition == "none": # no transition case
                pass
            else:
                $ renpy.transition(transition) # specified transition

            return
            
        else: # no transition specified, use default
            jump _noisy_return
        
    jump expression _game_menu_screen

The "_enter_game_menu" label is also slightly modified to:

Code: Select all

label _enter_game_menu(transition=None):
    $ _enter_menu()

    if transition == "none": # no transition case
        pass
    elif transition is not None:
        $ renpy.transition(transition)
    else:
        $ renpy.transition(config.enter_transition)

    if renpy.has_label("enter_game_menu"):
        call expression "enter_game_menu" from _call_enter_game_menu_1

    if config.game_menu_music:
        $ renpy.music.play(config.game_menu_music, if_changed=True)

    return

Modifying the common Renpy files makes me a bit nervous, but at least it works for now... xD
