How to use python functions with imagebuttons?

[tmp0000]

Hi all. Can't understand why my code is not working.

I have an array with items and function to lose it.

Code: Select all

$ items = [("coin", "Lucky coin")];

python:
    def lose(search_item):
        global items
        for item in items:
            if (item[0] == search_item):
                items.remove(item)
                return True
        return False

If I use it in console or in dialog like so: $ lose('coin'), all seem to be okay.

But. When I try to use this function as an imagebutton action, strange things happen. I've googled and tried many variants (see comments before action string), and there were different errors. Function doesn't work or coin is losed but after that gameplay jumps somethere I can't control etc.

Code: Select all

screen inventory:
    zorder 111
    default tt = Tooltip(" ")
    frame:
        xalign 1.0
        background Solid("#0000")
        xmaximum 130
        ymaximum 450
        xfill True
        vbox:
            imagebutton auto "inventory/bag_%s.png" action SetVariable("invent", not invent)
            if invent:
                text tt.value
                hbox:
                    viewport id "box":
                        yinitial 9999
                        xmaximum 0.9
                        mousewheel True
                        draggable True
                        vbox:
                            for i in range(0, len(items)):
                                imagebutton:
                                    idle Image(GetFN(i))
                                    hover Image(GetFN(i))
                                    hovered tt.Action(GetHint(i))
                                    # tried Lose
                                    # Lose = renpy.curry(lose)
                                    # tried renpy.restart_interaction()
                                    action lose(items[i][0])

I don't understand what is going on and why. Spent a lot of time with no success. Please help.

Code: Select all

action Function(lose, items[i][0])

The same thing. Items seems to be losed, but one of the current dialog variants is clicked, and inventory screen doesn't update.

Try adding print(search_item) at the start of your function, then use Shift-O to bring up console after clicking the button - it'll either tell you whether the button is calling the function, or what is being passed into the function. We may be able to figure it out from there.

Also, I know I don't know how far down development you are, but you may want to change your items into objects instead of tuples, it may get more complicated if you want to associate other information such as price, long description, item type, even special properties with them later.

Thank you a lot. I did it another way.

I am quite skilled programmer, but in renpy all my skills are zero. I wroted a lot of classes, but these objects didn't save and then I rewrited them.
