Buttons in draggable vpgrid ignore drag attempts

[strayerror]

The setup:

- Picture a large grid of buttons, let's say for example 10x10, 100 buttons.
- There's space enough screen space to show a 5x4 subset.
- It's the basis for a puzzle where the goal is to find the "correct" button.
- I would like to be able to use draggable True on the vpgrid.
- All the buttons should have a hover effect.

The problem:

- Seemingly the only way to have a button respect hover is to assign an action, an alternative action is not enough.
- Indeed without action the alternate setting doesn't even function.
- With an action assigned (even a NullAction()), the mouse events that would cause the drag get swallowed and it's not possible to drag except by grabbing part of the grid between buttons. Which isn't viable without causing massive player confusion.

The code:

Code: Select all

screen the_grid():
    default goal = renpy.random.randint(0, 99)

    vpgrid:
        rows 10
        cols 10
        draggable True

    vpgrid:
        rows 10
        cols 10
        draggable True

        for i in xrange(0, 100):
            textbutton '[i]':
                action NullAction() # commenting this makes it draggable but disables the buttons
                alternate If(i == goal, Return('you win'), NullAction())
                background ('#fcc' if i == goal else '#ccc')
                hover_background '#cfc'
                text_color '000'
                xysize (config.screen_width / 5, config.screen_height / 4)

Thanks for reading!

you want use this one if I have read your post right that you want to drag something from the left to the right

Unfortunately I don't believe drags behave differently in this regard. The button would still swallow the drag attempt. Additionally as drags unconditionally render all content it would also incur a hefty performance cost when compared to the vpgrid which renders only children that will appear on screen to allow for smoother performance. Appreciate the suggestion though.
