@Karina, just to be clear, there is nothing wrong with
colors = ['purple', 'red', 'blue', 'orange', 'yellow', 'green', 'lightblue']
– for all-string arrays of this size, thestr.split()
version may just be more convenient to type. -

object has no attr _suspend_updates
https://docs.python.org/3/library/functions.html are cool things to study as you learn Python. One of those is
dir(object)
which lists all the variables and methods of object. The message above means thatdir(object)
does not contain_suspend_updates
but some code is assuming that it does. Practice a lot withdir(object)
because it will help you to anticipate bugs. -

- Give us some code that generates this error --and/or--
- Give us the full multiline error message (stack trace) so we can understand the context of the error.
We do not even know the datatype of
object

Here's the code
from scene import * sw, sh = get_screen_size() rect_w = sw/3 rect_h = sh-100 class Board(ShapeNode): def __init__(self, stroke_color, line_width, parent, *args, **kwargs): self.stroke_color = stroke_color path=ui.Path.rect(0, 0, rect_w, rect_h) path.line_width = line_width self.parent = parent super.__init__(path, fill_color='white', stroke_color=self.stroke_color, parent=parent, *args, **kwargs) class Game(Scene): def setup(self): self.background_color = 'white' grey_rect = Board(stroke_color='grey', line_width=2, parent=self) rect.line_width = 10 board = Board(position=(sw/2, sh/2), stroke_color='purple', path=rect, parent=self) run(Game())
The idea is to create a rect in grey color line_width 2, and draw with it grey lines. Then draw above a purple rect above. I would draw that on paper, but i don't know how to add photos here
And the error - TypeError, 'Board' object has no attribute '_suspend_updates' -
@Karina some small errors:
- super without parenthesis
- rect.line_width but rect is not yet defined
- mix of positional and keyword parameters
-
@Karina not yet fully solved but this (incomplete) script works
from scene import * sw, sh = get_screen_size() rect_w = sw/3 rect_h = sh-100 class Board(ShapeNode): def __init__(self, stroke_color='grey', line_width=1, parent=None, *args, **kwargs): #self.stroke_color = stroke_color path=ui.Path.rect(0, 0, rect_w, rect_h) path.line_width = line_width #self.parent = parent super().__init__(path, fill_color='white', stroke_color=stroke_color, parent=parent, *args, **kwargs) class Game(Scene): def setup(self): self.background_color = 'white' grey_rect = Board(stroke_color='grey', line_width=2, parent=self) #rect.line_width = 10 board = Board(stroke_color='purple', line_width=10, parent=self, position=(sw/2, sh/2)) run(Game())

@cvp what do you mean super without parenthesis?
About rect - I tried different ways to initiate board and forgot to delete rect.line_width -

@cvp what did you change that it works now?

For now it’s like this
from scene import * import arrows sw, sh = get_screen_size() rect_w = sw/3 rect_h = sh-100 class Board(ShapeNode): def __init__(self, stroke_color='grey', line_width=1, parent=None, *args, **kwargs): path = ui.Path.rect(0, 0, rect_w, rect_h) path.line_width = line_width super().__init__(path, fill_color='white', stroke_color=stroke_color, parent=parent, *args, **kwargs) if stroke_color == 'grey': print(stroke_color) d = int(rect_w/30) for l in range(int(rect_w/d)): x = l*d path.move_to(x, 0) path.line_to(x, rect_h) class Game(Scene): def setup(self): self.background_color = 'white' grey_rect = Board(line_width=2, parent=self, position=(sw/2, sh/2)) board = Board(stroke_color='purple', line_width=10, parent=self, position=(sw/3, sh/2)) self.add_buttons() def add_buttons(self): ars = arrows.Main() self.present_modal_scene(ars) run(Game())
I use another pos in grey_rect to see that both are drawn, it shouldn’t be in the end like that
But here there’s no vertical grey lines, though they in init. And it prints ‘grey’, so he gets in that for -

Check the differences in positional/keyword parameters in

Put the draw lines before the super().init....
if stroke_color == 'grey': print(stroke_color) d = int(rect_w/30) for l in range(int(rect_w/d)): x = l*d path.move_to(x, 0) path.line_to(x, rect_h) super().__init__(path, fill_color='white', stroke_color=stroke_color, parent=parent, *args, **kwargs)

@Karina 😥 and a small correction
#grey_rect = Board(line_width=2, parent=self, position=(sw/2, sh/2)) board = Board(stroke_color='purple', line_width=10, parent=self, position=(sw/3, sh/2)) grey_rect = Board(line_width=2, parent=self, position=(sw/3, sh/2))
-
@cvp that correction I can do 😅
It was at the beginning before super, but somehow didn’t work. So I put after. And what changes if it’s after super? -
@cvp By the way do you know how to allow multi_touch? This for another thing that is nearly ready
