Question

playerOnePosition = (WINDOWHEIGHT - PADDLESIZE) /2

y = 0
moveY = 0

#Creates Rectangles for ball and paddles.
paddle1 = pygame.Rect(PADDLEOFFSET,(playerOnePosition,(y)), LINETHICKNESS,PADDLESIZE)

drawPaddle(paddle2)

clock = pygame.time.Clock()

while True: #main game loop
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        # mouse movement commands
        if (event.type == pygame.KEYDOWN):
            if(event.key == pygame.K_DOWN):
                moveY = -5
            if (event.key == pygame.K_UP):
                moveY = 5
        if (event.type == pygame.UP):
            if(event.key == pygame.K_DOWN):
                moveY = 0
            if (event.key == pygame.K_UP):
                moveY = 0
    y += moveY

    clock.tick(50)

我的代码中的这部分工作不正常，我试图设置按键使拍板上下移动，但我无法弄清楚我的代码有什么问题。

错误是：Argument must be rect style object

Answer 1

不起作用的一行就是这一行：

paddle1 = pygame.Rect(PADDLEOFFSET,(playerOnePosition, (y)), LINETHICKNESS,PADDLESIZE)

Rect expects four (or two, or one) parameters:

class pygame.Rect
  用于存储直角坐标的pygame对象
  Rect(left, top, width, height) -> Rect
  Rect((left, top), (width, height)) -> Rect
  Rect(object) -> Rect

所以PADDLEOFFSET为left，LINETHICKNESS为width，PADDLESIZE为height。

但对于top，您有(playerOnePosition, (y))，这是一个元组，而不是Rect所期望的整数。将其更改为整数，它将起作用。

Argument must be rect style object是Rect类在参数类型错误时引发的一般错误消息。

参数必须是rect样式对象
