Question

以下是我的程序中控制得分的代码段。问题在于，每次触及右侧墙壁和左侧平底板时，它会在分数上加1，并且每当触及左侧墙壁时，它也会减去一个点。当它应该做的只是每次触及右墙时添加一个。

    FRAMECLOCK = pygame.time.Clock() #set frame rate
    SURFACEDISPLAY = pygame.display.set_mode((WIDTH,HEIGHT)) #Clear the surface on refresh
    pygame.display.set_caption ('Pong') #title of window 

    ballX = WIDTH/2 - PLACEMENTMARKER/2 #ball position on X axis at the start
    ballY = HEIGHT/2 - PLACEMENTMARKER/2 #ball position on Y axis at the start
    playerOnePosition = (HEIGHT - PADDLESIZE) /2 #paddle one position at the start
    playerTwoPosition = (HEIGHT - PADDLESIZE) /2 #paddle two position at the start
    score = 0

    #Sets starting position movement
    ballDirX = -1 #-1 = left 1 = right
    ballDirY = -1 # -1 = up 1 = down

    paddle1 = pygame.Rect(PADDLEDISTANCE,playerOnePosition, PLACEMENTMARKER,PADDLESIZE) #paddle one drawing 
    paddle2 = pygame.Rect(WIDTH - PADDLEDISTANCE - PLACEMENTMARKER, playerTwoPosition, PLACEMENTMARKER,PADDLESIZE) #paddle two drawing 
    ball = pygame.Rect(ballX, ballY, PLACEMENTMARKER, PLACEMENTMARKER)#ball drawing

    Pong() #calling the game surface in main function
    paddles(paddle1) #calling paddle 1 main function
    paddles(paddle2) #calling paddle 2 in main function
    pongball(ball) #calling ball in main function 

    while True: #game Loop
        for event in pygame.event.get(): #Checks to see if program is quit
            if event.type == QUIT:
                pygame.quit()
                sys.exit() #system quit

        Pong() #Otherwise it performs these functions 
        paddles(paddle1)
        paddles(paddle2)
        pongball(ball)

        displayScore(str(score))

checkscore功能正在重置分数，而不是减去分数。当你用桨击它时，它也明确地加了一个。

我已将此功能修改为仅在击中右墙时添加，而不是在击中左侧时减去：

let IP = "192.168.2.255"
let PORT:UInt16 = 6454
var socket:GCDAsyncUdpSocket!

func sendPacket(){
    socket = GCDAsyncUdpSocket(delegate: self, delegateQueue: dispatch_get_main_queue())
    let message = "test"
    let data = message.dataUsingEncoding(NSUTF8StringEncoding)
    socket.sendData(data, toHost: IP, port: PORT, withTimeout: 2, tag: 0)
}

只需用当前def checkscore (paddle1, ball, score, ballDirX): #this is where the program resets after a point is scored if ball.right == WIDTH - PLACEMENTMARKER: score += 1 return score #no points scored, return score unchanged else: return score替换此函数，一切都可以正常工作

我假设你至少复制了大部分内容，请确保彻底阅读所有内容并尝试理解每一点。

Pong比赛得分保持在Pygame
