Screen that's modal or not based on its parameters

[jackmcbarn]

I have a screen like this:

Code: Select all

screen my_screen(should_be_modal):
    modal should_be_modal
    text "Hello World"

If I do show screen my_screen(False), I get NameError: name 'should_be_modal' is not defined. What do I have to do to make a screen that's modal sometimes, depending on its parameters?

You could try

Code: Select all

default should_be_modal=False

screen my_screen(should_be_modal):
    modal should_be_modal
    text "Hello World"

The way above doesn't appear to work for me, throws an error that the parameter has no value and if I try to forcefully give it a value within the screen itself it returns

Code: Select all

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.

File "game/script.rpy", line 98: a non-constant keyword argument like 'modal should_be_modal' is not allowed after a python block.
    modal should_be_modal
                         ^

A simpler approach, would be to use show screen for when you want the screen non-modal and call screen when you want the screen to be modal.

Based on the errors, it seems that modal is "processed" at initialization, thus it can be only constant.
I also tried this:

Code: Select all

screen my_screen(should_be_modal):
    if should_be_modal:
        modal True
    text "Hello World"

No errors this way, but the screen is not modal even if should_be_modal = True.

Using show statements with modal True still make the screen modal and you won't be able to interact with other displayable or dialogues.
You can try using two identical screens (one modal, the other is not). However, it is better to find another approach to do what you want.

The method with default should_be_modal outside of the screen seems to work, but you can't use it as argument to the screen.

Code: Select all

default should_be_modal = True  
  
screen my_screen():
    
    modal should_be_modal
    textbutton "Return" action [Hide('my_screen'), Return()]

label start:

    show screen my_screen()

    "Right now the screen is modal."

    "Right now the screen is hidden." # if you pressed the Return button

    "Let's set should_be_modal to False and try again."
   
    $ should_be_modal = False

    show screen my_screen()
    
    "Now it's not modal."
