""" ==========Task=============== 1. Create two more ball objects (ball2, and ball3) making them different colours and at different locations to ball1 HINT: In order to do this you need to a) Put the line: self.canvas.move(self.id,0,0) #this moves the oval to the specified location in it's own method called "move" b) The method must call the parameters 'self', 'x' and 'y' (x and y are the x and y positions) c) When inside the move method simply use: canvas.move(self.id,x,y) 2. Play around with the size and shape of the "ball" .....this is in the __init__ method """ from tkinter import * import random import time class Ball: #create a ball class def __init__(self,canvas,color): #initiliased with the variables/attributes self, canvas, and color self.canvas=canvas #set the intiial values for the starting attributes self.id=canvas.create_oval(30,30,50,50,fill=color) #starting default values for the ball """ Note: x and y coordinates for top left corner and x and y coordinates for the bottom right corner, and finally the fill colour for the oval """ self.canvas.move(self.id,0,0) #this moves the oval to the specified location def draw(self): #we have created the draw method but it doesn't do anything yet. pass tk=Tk() tk.title("My 21st Century Pong Game") tk.resizable(0,0) tk.wm_attributes("-topmost",1) canvas=Canvas(tk,bg="white",width=500,height=400,bd=0,highlightthickness=0) canvas.pack() tk.update() ball1=Ball(canvas,'green') #here we are creating an object (green ball) of the class Ball
