Frame for tetris

[Karina]

Hello everyone
I'm new to pythonista and programming, trying to write tetris
For now i have buttons⬅️⬆️⬇️➡️ and a frame. But yhe frame is to much in the corner and i can't move it
Here's the code

import arrows
from scene import *

colors = ['purple', 'red', 'blue', 'orange', 'yellow', 'green',
'lightblue']
sw = get_screen_size()[0]
sh = get_screen_size()[1]

class Board(ShapeNode):
     def __init__(self, parent=None, *args, **kwargs):
          self.rect_w = sw/2
          self.rect_h = sh-100
          path = ui.Path.rect(0, 0, self.rect_w, self.rect_h)
          path.line_width = 10
          super().__init__(path,
                           fill_color='white',
                           stroke_color='purple',
                           parent=parent,
                           *args, **kwargs)

     def draw_lines(self):
          stroke(0, 0, 0)
          stroke_weight(2)
          line(l*30+50, self.rect_h+50, l*30+50, 50)

class Game(Scene):
     def setup(self):
          self.background_color = 'white'
          Board(parent=self)
          self.add_buttons()

     def add_buttons(self):
          ars = arrows.Main()
          self.present_modal_scene(ars)

if __name__ == '__main__':
     run(Game())

In the line path = ui.Path.rect(0, 0, self.rect_w, self.rect_h) if i change first two args from zero, nothing changes. So what they do? And how i can change pos of the frame?

@ccc with sw sh okay, but what this colors = ‘purple red blue orange yellow green lightblue'.split() gives?

[cvp]

@ccc said:

colors = ‘purple red blue orange yellow green lightblue'.split()

@Karina Try and print colors, you will see

['purple', 'red', 'blue', 'orange', 'yellow', 'green', 'lightblue'] 

Thus what you want 😀

[mikael]

@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, the str.split() version may just be more convenient to type.

[Karina]

@ccc @cvp @mikael I got it with the colors, but to me it’s the same amount of writing
And what means the error ‘ ‘ object has no attr _suspend_updates? When it appears?

[cvp]

@Karina said:

same amount of writing

Not really, with @ccc advice, you don't need to type quotes and comma's

[ccc]

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 that dir(object) does not contain _suspend_updates but some code is assuming that it does. Practice a lot with dir(object) because it will help you to anticipate bugs.

[mikael]

@Karina, _suspend_updates is new to me, but it sounds like it is a scene-internal attribute. In addition to the detective work with dir as @ccc suggested, it is a good idea to look at/share the full traceback.

[Karina]

@ccc @mikael I thought maybe you have met it then I’ll know what to do. And in google I also didn’t found about this error.
And if I see in dir that there is no _suspend_updates how it will help me? I just don’t understand what to do to avoid this bug

[ccc]

1. Give us some code that generates this error --and/or--
2. 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'

[cvp]

@Karina some small errors:

• super without parenthesis
• rect.line_width but rect is not yet defined
• mix of positional and keyword parameters

[cvp]

@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()) 

[Karina]

@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]

@Karina you wrote

super.__init__ 

instead of

super().__init__ 

[Karina]

@cvp what did you change that it works now?

[Karina]

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

def __init__(...

@Karina said:

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)
