我一直在使用 Python 的 Pygame 通过 Livewires 编写一个简单的乒乓球游戏。我已经发布了这个问题和一个运行完美的类似示例游戏代码,因为这里的每个人都不会精通 livewires 和/或 pygame。
这是有错误的代码。发生的情况是窗口打开,并且“Ball”对象运行良好并且从屏幕上掉下来(它应该是不完整的),并且“Slab”对象被卡在鼠标最初所在的位置。这里是:
from livewires import games, color
games.init (screen_width = 640, screen_height = 480, fps = 50)
class Ball (games.Sprite):
def iMove (self):
self.dx = -self.dx
self.dy = -self.dy
class Slab (games.Sprite):
def mouse_moves (self):
self.x = games.mouse.x
self.y = games.mouse.y
self.iCollide()
def iCollide (self):
for Ball in overlapping_sprites:
Ball.iMove()
def main():
#Backgrounds
pingpongbackground = games.load_image ("pingpongbackground.jpg", transparent = False)
games.screen.background = pingpongbackground
#Ball: Initializing object and setting speed.
ballimage = games.load_image ("pingpongball.jpg")
theball = Ball (image = ballimage,
x = 320,
y = 240,
dx = 2,
dy = 2)
games.screen.add(theball)
#Paddle: Initializing ping pong object and setting initial poisition to the initial mouse position
slabimage = games.load_image ("pingpongpaddle.jpg")
theslab = Slab (image = slabimage,
x = games.mouse.x,
y = games.mouse.y)
games.screen.add(theslab)
games.mouse.is_visible = False
games.screen.event_grab = True
games.screen.mainloop()
main ()
这是一段类似的功能代码:
# Slippery Pizza Program
# Demonstrates testing for sprite collisions
from livewires import games
import random
games.init(screen_width = 640, screen_height = 480, fps = 50)
class Pan(games.Sprite):
"""" A pan controlled by the mouse. """
def update(self):
""" Move to mouse position. """
self.x = games.mouse.x
self.y = games.mouse.y
self.check_collide()
def check_collide(self):
""" Check for collision with pizza. """
for pizza in self.overlapping_sprites:
pizza.handle_collide()
class Pizza(games.Sprite):
"""" A slippery pizza. """
def handle_collide(self):
""" Move to a random screen location. """
self.x = random.randrange(games.screen.width)
self.y = random.randrange(games.screen.height)
def main():
wall_image = games.load_image("wall.jpg", transparent = False)
games.screen.background = wall_image
pizza_image = games.load_image("pizza.bmp")
pizza_x = random.randrange(games.screen.width)
pizza_y = random.randrange(games.screen.height)
the_pizza = Pizza(image = pizza_image, x = pizza_x, y = pizza_y)
games.screen.add(the_pizza)
pan_image = games.load_image("pan.bmp")
the_pan = Pan(image = pan_image,
x = games.mouse.x,
y = games.mouse.y)
games.screen.add(the_pan)
games.mouse.is_visible = False
games.screen.event_grab = True
games.screen.mainloop()
# kick it off!
main()
任何见解都将不胜感激!
