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,

          #rect.line_width = 10
          board = Board(stroke_color='purple', line_width=10, parent=self, position=(sw/2, sh/2))

@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

@Karina said:

Check the differences in positional/keyword parameters in

def __init__(...

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)

cvp

@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))

Karina

@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?

Karina

@cvp By the way do you know how to allow multi_touch? This for another thing that is nearly ready

cvp

@Karina said:

And what changes if it’s after super?

If you do "after super().init..", you already have passed the path to node creation and all lines are added to the object path but not to the path of the node it-self

cvp

@Karina said:

how to allow multi_touch?

A "must have" of @mikael : gestures

mikael

@Karina, is this recent thread relevant to your multi-touch question?

Karina

@mikael yes, I want to do smth like that. I’ll also look in github, but I didn’t use it before

Karina

@cvp @mikael sorry, I have another problem. I still can’t writing smth by myself🙂

I tried here to add a block on the board, but it doesn’t show it. But prints the position

from scene import *
import random
import arrows

sw, sh = get_screen_size()
rect_w = sw/3  #343.33
rect_h = sh-100  #668
side = int(rect_w/10)
colors = ['red']

class Board(ShapeNode):
	def __init__(self, stroke_color='lightgrey', line_width=1, parent=None, *args, **kwargs):
			path = ui.Path.rect(0, 0, rect_w, rect_h)
			path.line_width = line_width
			
			if stroke_color == 'lightgrey':
				d = int(rect_w/10)
				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)
		


class Game(Scene):
	def setup(self):
		self.background_color = 'white'
		grey_rect = Board(line_width=2, parent=self, position=(sw/3, sh/2), z_position=0)
		self.board = Board(stroke_color='purple', line_width=15, parent=self, position=(sw/3, sh/2), 	z_position=-1)
		self.add_buttons()
		self.add_figure()
		
	def add_buttons(self):
		ars = arrows.Main()
		self.present_modal_scene(ars)
		
	def add_figure(self):
		x = random.choice(range(10)) * side
		y = rect_h
		block = SpriteNode('pzl:Yellow7', (x, y), z_position=1, size=Size(side, side), parent=self.board)
		print(block.position)


run(Game())  ```

cvp

@Karina try the gray_rect as parent for yours blocks because it is above the board

        self.grey_rect = Board(line_width=2, parent=self, position=(sw/3, sh/2), z_position=0)

and don't forget child position is versus the center of the parent node

    def add_figure(self):
        r = random.choice(range(10)) 
        x = r * side - rect_w/2 + side/2
        y = rect_h/2 - side/2
        block = SpriteNode('pzl:Yellow7', position=(x, y), size=Size(side, side), parent=self.grey_rect)
        
        #print(block.position)

cvp

@Karina Here, if you let self.board as parent and use r = 10, you can see that your block is partially hidden by the grid

        r = 10
        x = r * side - rect_w/2 + side/2
        y = rect_h/2 - side/2
        block = SpriteNode('pzl:Yellow7', position=(x, y), size=Size(side, side), parent=self.board)#self.grey_rect)
