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?

cvp

@Karina try this

          Board(position=(sw/2,sh/2), parent=self)

Karina

@cvp 👍 and what 2 first args do in ui.Path.rect()?
Thanks for help🤗

cvp

@Karina I think that as used here in ShapeNode path, x and y are not used, only width and height. If you draw an ui.path in general, x and y set path position, but not here.

Karina

@cvp Thank you now the frame where it needs to be.
Then I need to draw vertical lines in the frame, but it doesn’t work. And if change z_position - nothing.

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, 
						 z_position=-1,
						 fill_color='white',
						 stroke_color='purple',
						 parent=parent,
						 *args, **kwargs)
	
	
	
	def draw_lines(self):
		fill(0, 0, 0)
		stroke_weight(2)
		rect(sw-200, sh/2, 100, 100)
		for l in range(int(self.rect_w/30)):
			line_path = ui.Path.rect(sw/3 - self.rect_w/2 + 30*l, sh/2 + self.rect_h/2, 
									 self.rect_w, self.rect_h)
			
		
			

class Game(Scene):
	def setup(self):
		self.background_color = 'white'
		self.board = Board(position=(sw/3, sh/2), parent=self)
		self.add_buttons()
		
	
	
	def draw(self):
		self.board.draw_lines()
		
		
	def add_buttons(self):
		ars = arrows.Main()
		self.present_modal_scene(ars)



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

But beyond the purple frame I can draw😐

cvp

@Karina sincerely, not sure this is what you want. If not, sorry and forget quickly this post

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 = 2
        d = int(self.rect_w/30)
        for l in range(int(self.rect_w/d)):
            x = l*d
            path.move_to(x,0)
            path.line_to(x,self.rect_h) 
.
.
.

Comment temporarily your draw_lines process, to watch the result

Karina

@cvp It’s nearly what I need, I just want it in grey color. But when I put it into the draw_lines and not Board’s init, it doesn’t work. And I don’t want to overload init

cvp

@Karina it does not work because you pass the path to super.init and thus when you draw the lines, the path is already built

This is not really an overload

cvp

@Karina please read some @jonB explanations in this topic

@Karina said:

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

colors = ‘purple red blue orange yellow green lightblue'.split()
sw, sh = get_screen_size()

@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

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.
