Hey There Everyone,
I'm following an example in a book and I can't find the error that's
preventing this program from running. It's just an example of how to get a
sprite moving. The images are all in the right folder. I can run the program
and get a stationary sprite to appear. The trouble seems to come up when I add
"dx" and "dy" Here's the code.
from livewires import games
SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480
class Pizza(games.Sprite):
"""A falling pizza."""
def __init__(self, screen, x, y, image, dx, dy):
"""Initialize pizza object."""
self.init_sprite(screen = screen, x = x, y = y, image = image,
dx = dx, dy = dy)
#main
my_screen = games.Screen(SCREEN_WIDTH, SCREEN_HEIGHT)
wall_image = games.load_image("skywall.png", transparent = False)
my_screen.set_background(wall_image)
pizza_image = games.load_image("pizza.png")
Pizza(screen = my_screen, x = SCREEN_WIDTH/2, y = SCREEN_HEIGHT/2,
image = pizza_image, dx = 0, dy = 1)
my_screen.mainloop()
___________
Here's the error message:
Traceback (most recent call last):
File "C:/Python25/Chapter 11/movingsprite.py", line 25, in <module>
image = pizza_image, dx = 0, dy =1)
File "C:/Python25/Chapter 11/movingsprite.py", line 15, in __init__
dx = dx, dy = dy)
TypeError: init_sprite() got an unexpected keyword argument 'dx'
Thanks in advance for any help you can give me. :-)
