Pong Game Score Keeping in Pygame - function

Question

Here is the code segment from my program which controls the score keeping. The problem is that it adds 1 to the score each time it touches the right wall as well as the left paddle, and it also subtracts a point whenever it touches the left wall. When all it should be doing is adding one every time it touches the right wall.
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))

Answer 1

The checkscore function was resetting the score, not subtracting it. It is also explicitly adding one when you hit it with the paddle.
I've modified the function to only add when hitting the right wall and not subtracting upon hitting the left:
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
just substitute this function with the current checkscore() and everything should work
I'm assuming you've copied at least a large majority of this, make sure you read through everything thoroughly and try to understand each bit.
