how to create a draggroup in a python function?

[Sevlac]

Hi, I try to make a cross math minigame that should look like this.

but right now it look like this.

So, my problem is that the drags don't go on the correct position and they are not draggable.
What should I change?

(I tried to change the position of my drags after adding draggroup in the screen but it does nothing.)

Here is my code

Code: Select all

init python:
    level1field = [["0","+","7","=","17","n","n","n","n"],["+","n","+","n","n","n","n","n","n"],["0","n","0","n","0","+","3","=","0"],["=","n","=","n","-","n","n","n","n"],["19","-","0","=","7","n","n","n","n"],["n","n","n","n","=","n","n","n","n"],["n","n","n","n","10","n","n","n","n"],["n","n","n","n","n","n","n","n","n"],["n","n","n","n","n","n","n","n","n"]]
    level1answers = ["10","9","5","17","20","12"]
    square_list = []
    square_answer_list = []
    blank_square_list = []

    class square_info:
        def __init__(self, name, xposition, yposition, value, ison=None):
            self.name = name
            self.xposition = xposition
            self.yposition = yposition
            self.value = value
            self.ison = ison

    def create_draggroup(levelfield,levelanswers):
        square_answer_list.clear()
        blank_square_list.clear()
        for truc in square_list:
            my_draggroup.remove(my_draggroup.get_child_by_name(truc.name))
        square_list.clear()
        #gap between each square
        gap = 48

        top_gap = 200
        left_gap = 50
        xsquare_pos = left_gap
        ysquare_pos = top_gap
        answer = 0
        cpt = 0
        for line in levelfield:
            for case in line:
                if case != "n":
                    # case with 0 value is a blank square
                    if case != "0":
                        my_draggroup.add(Drag(d = Fixed("square.png",Text(case, color = "#000000ff", size = 25, align=(0.5, 0.5))), drag_name = cpt, draggable = False, droppable = False, xypos = (xsquare_pos,ysquare_pos))) 
                        tmp_square = square_info(name = cpt, xposition=xsquare_pos, yposition=ysquare_pos, value=case)
                        square_list.append(tmp_square) 
                    else:

            xsquare_pos = left_gap
        xsquare_pos = 500
        ysquare_pos = 500
        for square_answer in levelanswers:
