Hey there.

I 've been trying to create the Pong Game in Pythonista.
I have created the game in my PC using python's tkinter module.

However, I am having a difficulty in which library to use. Scene? Ui?

Till now I have tried:

import scene


class TutoScene1(scene.Scene):
    def setup(self):
        self.background_color = 'green'
        self.item = scene.ShapeNode(scene.rect(0,0,0,0), color = 'red', position = (self.size.w / 2, self.size.h / 2), anchor_point = (0.5, 0.5), parent = self)

    def update(self):
        max_speed = 5
        x, y, z = scene.gravity()
        pos = self.item.position
        pos.x = self.item.position.x + x * max_speed
        pos.y = self.item.position.y + y * max_speed
        self.item.position = pos


scene.run(TutoScene1(), scene.PORTRAIT)

And:

import scene
import ui


class TutoScene2(scene.Scene):
    def setup(self):
        self.background_color = 'black'
        self.paddle = ui.Path.rect(0, 0, 200, 50)
        self.ball = ui.Path.oval(100, 100, 400, 200)


scene.run(TutoScene2(), scene.PORTRAIT)

In the first example dimensions don't work as they should (I get the same Rect no matter the x, y, width, height and in the 2nd example I don't know how to make things slow up (like give them colors etc)

Here is an example pong program. I hope it helps. (It is not well tested. It is just for illustration.)
