Scene_drawing help!

[amharder]

I am trying to use scene_drawing to create a chessboard, and it is not going well at all, no matter what coordinates I put in for each square, it outlines the entire scene, please help! First post, should I enter my code or should I not?

scene_drawing is sort of deprecated. Use ShapeNode Here is an example to display chessboard grid You can tap a square to place a queen.

# coding: utf-8
import scene, ui

class Block(scene.ShapeNode):
    def __init__(self, x, y, w, h,
        fill_color='black', parent=None):
        path = ui.Path.rect(0, 0, w, h)
        self.label = None
        self.root = parent        
        super(Block, self).__init__(path=path,
            fill_color=fill_color,
            position=(x, y),
            parent=parent)
            
    def touch_began(self, touch):
        if not self.label:
            self.label = scene.LabelNode('♛', 
            font=('Helvetica', 40),
            color='green', parent=self.root)
            self.add_child(self.label)
           
class MyScene (scene.Scene):        
    def setup(self):
        self.background_color = 'gray'
        colorlist = ['black', 'lightyellow']
        m, n = 8, 8
        w, h = 64, 64
        start_x, start_y = self.size[0]/2-n/2*w, self.size[1]/2 - m/2*h
        self.grid = {}
        for i in range(m):
            for j in range(n):
                x, y = start_x+i*w, start_y+j*h
                self.grid[i,j] = Block(x, y, w, h,
                    fill_color=colorlist[(i+j)%2],
                    parent=self)

    def touch_began(self, touch):
        for i, j in self.grid:
            if (touch.location in (self.grid[i, j].frame)):
                self.grid[i,j].touch_began(touch)
                return
        
scene.run(MyScene(), show_fps=True)
