How to return deleted objects DragGroup?

[Pronax]

Hi
I have a code in which when dragging a thing to a certain place, this thing, to hide itself from the screen, is removed across .remove(child) from DragGroup()

Code: Select all

    def fruit(drags, drop):
        global karzina_pl, karzina_srav, prav_list, p


        if not drop:

            drags[0].snap(pos_f[int(drags[0].drag_name.split("-")[0])][0], pos_f[int(drags[0].drag_name.split("-")[0])][1], delay=0.1)
            return
        
        else:
            print (karzina_pl, karzina_srav, prav_list)

            if str(drags[0].drag_name.split("-")[1]) in prav_list:
                stall.remove(drags[0])

                karzina_pl.append(drags[0].drag_name.split("-")[2]) 
                karzina_srav.append(drags[0].drag_name.split("-")[1]) 


                for k in karzina_srav:

                    if (k in prav_list) and (len(karzina_srav) == len(prav_list)):
                        remove_drags()

                        karzina_srav = []
                        prav_list = []
                        p = 1

                        stall.add(apple)
                        # stall.add(pear)
                        # stall.add(banana)
                        # stall.add(melon)
                        stall.add(cherry)
                        stall.add(basket)


                        return True
            else:
                p += 1

                if p >= p_max:
                    renpy.jump("noob")
                else: 
                    return 

There is also a function by which is determined what exactly should be dragging and therefore retire, when I start it, I have to add all the elements to the screen using across .add (child)

Code: Select all

    def add_drags():
        global spis, stall

        stall.add(apple)
        stall.add(pear)
        stall.add(banana)
        stall.add(melon)
        stall.add(cherry)
        stall.add(basket)


    def zapros(item1=None, item2=None, item3=None, item4=None, item5=None):
        global prav_list, vsego_slovar, spis_func, stall           
        prav_list = []

        spis_func = [item1, item2, item3, item4, item5] 

        for i in spis_func: 
            if i != None:               
                for what in vsego_slovar.keys():          
                    if i.title() == what.title(): ## Compare the entered values with a common dictionary
                        prav_list.append(vsego_slovar[i]) ## Add our items to the final customer list
                        print (vsego_slovar[i])

        add_drags()

When I first call this function everything works fine, but when I try to call the function a again I get this error:

• Code: Select all

  I'm sorry, but an uncaught exception occurred.

I declared variables like this:

Code: Select all

stall = DragGroup()

    apple = Drag(
        drag_name = "0-apple-Apple",
        d = "apple.png",
        droppable = False,
        dragged = fruit,
        pos = (pos_f[0][0], pos_f[0][1])
    )

    pear = Drag(
        drag_name = "1-pear-Pear",
        d = "pear.png",
        droppable = False,
        dragged = fruit,
        xpos =pos_f[1][0],
        ypos =pos_f[1][1]
    )

    banana = Drag(
        drag_name ="2-banana-Banana",
        d = "banana.png",
        droppable =False,
        dragged =fruit,
        xpos =pos_f[2][0], 
        ypos =pos_f[2][1]
    )

    melon = Drag(
        drag_name ="3-melon-Melon",
        d = "melon.png",
        droppable =False,
        dragged= fruit,
        xpos =pos_f[3][0], 
        ypos= pos_f[3][1]
    )

    cherry = Drag(
        drag_name= "4-cherry-cherry",
        d = "cherry.png",
        droppable= False,
        dragged= fruit,
        xpos= pos_f[4][0],
        ypos =pos_f[4][1]
    )

    ## Dropped
    basket = Drag(
        drag_name ="basket",
        d =  "basket.png",
        draggable = False,
        xpos= 450,
        ypos =140
    )

And I call this:

Code: Select all

screen producti:
    add "menu.jpg"

    add stall

label start:

    $ zapros("Pear", "Banana", "Melon")

    "[prav_list]" ## We check that we set everything correctly

    call screen producti 
    $ karzz = " ".join(karzina_pl) ## Displaying list items
    "In our basket [karzz]."

    $ zapros("Pear", "Banana", "Melon")
    call screen producti

And she gets out only on those items that were previously removed.
How to fix this problem? In the Internet there is nothing on this subject(

P.S.
Forgive me for my English - this is not my native language.

A quick workaround (untested guesswork)

Amend
if not drop:
... drags[0].snap( ...

to
if not drop and drags[0].x:
... drags[0].snap( ...

If that doesn't work you may need to adjust the child.target_at after doing the remove

[Pronax]

Your method does not work, alas.
But thank you very much for the hint with the child.target_at!
Inserting this simple block before return True:

Code: Select all

apple.snap(pos_f[0][0], pos_f[0][1])
pear.snap(pos_f[1][0], pos_f[1][1])
banana.snap(pos_f[2][0], pos_f[2][1])
melon.snap  (pos_f[3][0], pos_f[3][1])
cherry.snap(pos_f[4][0], pos_f[4][1])

apple.target_at = 0
pear.target_at = 0
banana.target_at = 0
melon.target_at = 0
cherry.target_at = 0

It all worked for me!
Thanks again.

Nicely done
