我是pygame的初学者。最近我编写了一个import pygame, sys, time,math
from pygame.locals import *
# User-defined functions
def main():
# Initialize pygame
pygame.init()
# Set window size and title, and frame delay
surfaceSize = (500, 400) # window size
windowTitle = 'Pong' #window title
frameDelay = 0.005 # smaller is faster game
# Create the window
pygame.key.set_repeat(20, 20)
surface = pygame.display.set_mode(surfaceSize, 0, 0)
pygame.display.set_caption(windowTitle)
# create and initialize red dot and blue dot
gameOver = False
color1=pygame.Color('white')
center1 = [250, 200]

score=[0, 0]

size=(5, 100)
position1=(0,0)
position2=(350,0)
rect1=pygame.Rect(location1,size)
rect2=pygame.Rect(location2,size)
# Draw objects
pygame.draw.circle(surface, color1, center1, radius1, 0)
# Refresh the display
pygame.display.update()
# Loop forever
while True:

for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()

eraseColor=pygame.Color('Black')
surface.fill(eraseColor)
moveDot(surface,center1,radius1,speed1,score,position1,position2)
pygame.draw.circle(surface,color1,center1,radius1,0)

#Moves the ball by changing the center of the ball by its speed
#If dots hits left edge, top edge, right edge or bottom edge
#of the window, the then the ball bounces
size=surface.get_size()
for coord in range(0,2):
center[coord]=center[coord]+speed[coord]

游戏。
然而，当我按下键盘上的某些键时，我无法移动拨片。有人可以帮助我检查代码。我想也许我在给桨位的新位置时遇到了一些问题。但我无法解决它。希望能给我一些提示。
谢谢！
以下代码：

您总是使用rects rect1和rect2绘制您的拨片。但要更新其排名，请尝试更改列表location1和location2中的值。
停止它。只是改变rects。最简单的方法是使用move_ip更改适当的位置。
另外，如果你想在玩家按住移动键的同时保持你的拨片移动，请使用pygame.key.get_pressed获取所有按键的列表（因为按一个键只会生成一个KEYDOWN事件，除非你弄乱pygame.key.set_repeat，你不应该这样做。
所以你的代码应该是这样的：
...
while True:
# Handle events
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
pressed = pygame.key.get_pressed()
if pressed[pygame.K_q]: rect1.move_ip(0, -1)
if pressed[pygame.K_a]: rect1.move_ip(0, 1)
if pressed[pygame.K_p]: rect2.move_ip(0, -1)
if pressed[pygame.K_i]: rect2.move_ip(0, 1)
gameOver = ...
