I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. However, I keep getting the error: "Cannot have more than on Screen object", which I can find no references to online really, and I can't make sense of it. I want to eventually make the game more complicated, but I need to make it work first. Help please! Here's the code so far:
from livewires import games
games.init(screen_width=640, screen_height=480, fps=50)
class Paddle(games.Sprite):
image=games.load_image("paddle.bmp")
def __init__(self):
super(Paddle, self).__init__(image=Paddle.image,
y=games.mouse.y,
left=0)
self.score=games.Text(value=0, size=25, top=5, right=games.screen.width-10)
games.screen.add(self.score)
def update(self):
self.y=games.mouse.y
self.check_collide()
def check_collide(self):
for ball in self.overlapping_sprites:
self.score.value+=1
self.score.right=games.screen.width-10
ball.handle_collide()
class Ball(games.Sprite):
image=games.load_image("ball.bmp")
speed=1
def __init__(self, x, y=90):
super(Ball, self).__init__(image=Ball.image,
x=x, y=y,
dx=Ball.speed, dy=Ball.speed)
def update(self):
if self.left<0:
self.end_game()
self.destroy()
def handle_collide(self):
if self.right>games.screen.width:
self.dx=-self.dx
if self.bottom>games.screen.height or self.top<0:
self.dy=-self.dy
def ball_destroy(self):
self.destroy()
def main():
background_image=games.load_image("background.bmp", transparent=False)
games.screen.background=background_image
the_ball=Ball()
games.screen.add(the_ball)
the_paddle=Paddle()
games.screen.add(the_paddle)
games.mouse.is_visible=False
games.screen.event_grab=True
games.screen.mainloop()
main()
