ShapeNode.path.hit_test() mirrored

[dashorty]

I want to test if the user touch (hit) the Shape (triangle) but the path is mirrored. why?
here is my sample code

# coding: utf-8

from scene import *
import sound
import random
import math
from ui import Path
A = Action

class MyScene (Scene):
    def setup(self):
        h = 200  
        w = 300
        p = Path()
        p.line_to(w/2, h)
        p.line_to(-(w/2), h)
        p.close()
        self.s = ShapeNode(p)
        self.s.anchor_point = (0.5, 0)
        self.s.position = (self.size.x/2, self.size.y/2)
        self.add_child(self.s)
        
        ph = Path()
        ph.line_to(self.size.x, 0)
        ph.line_to(self.size.x, 1)
        ph.line_to(0, 1)
        ph.close()
        self.lh = ShapeNode(ph)
        self.lh.fill_color = 'red'
        self.lh.position = (self.size.x/2, self.size.y/2)
        self.add_child(self.lh)
        
        pv = Path()
        pv.line_to(0, self.size.y)
        pv.line_to(1, self.size.y)
        pv.line_to(1, 0)
        pv.close()
        self.lv = ShapeNode(pv)
        self.lv.fill_color = 'red'
        self.lv.position = (self.size.x/2, self.size.y/2)
        self.add_child(self.lv)
        
    def did_change_size(self):
        pass
    
    def update(self):
        pass
    
    def touch_began(self, touch):
        pass
    
    def touch_moved(self, touch):
        
        node_x, node_y = self.s.point_from_scene(touch.location)
        self.lh.position = (self.lh.position.x, touch.location.y)
        self.lv.position = (touch.location.x, self.lv.position.y)
        if self.s.path.hit_test(node_x, node_y):
            self.s.fill_color = 'green'
        else:
            self.s.fill_color = 'white'
    
    def touch_ended(self, touch):
        pass

if __name__ == '__main__':
    run(MyScene(), show_fps=False)

The ui and scene modules have different coordinate systems. In ui, the origin (0, 0) is the top-left corner, in scene, it's the bottom-left (i.e. the y axis is flipped).

As a simple fix in your case, you could flip the node_y value back:

  # ...
  def touch_moved(self, touch):
    node_x, node_y = self.s.point_from_scene(touch.location)
    node_y = self.s.frame.h - node_y
    # ...
