from Tkinter import *
window = Tk()
canvas = Canvas(window, width=500, height=500, background="green")
canvas.pack()
def move_ball(speed_x, speed_y):
box = canvas.bbox("ball")
x1 = box[0]
y1 = box[1]
x2 = box[2]
y2 = box[3]
if x1 <= 0:
speed_x = 0
speed_y = 0
canvas.move("ball", speed_x, speed_y)
canvas.after(30, move_ball, speed_x, speed_y)
canvas.create_oval(225, 225, 275, 275, fill="blue", tags="ball")
move_ball(-10, 7)
mainloop()
where in the code should i change to make the ball bounce around forever. is
it the x and y?
