简单的乒乓球：但是球进入角落并以错误的方式反弹然后它一直循环我该如何解决这个问题？

Question

简单的乒乓球：但是在第 5 次击球时，球进入角球并从 player1 矩形以错误的方式垂直反弹，然后它到达角球中的对手 AI，也以错误的方式从 player1 矩形垂直反弹AI矩形，然后一直循环。我怎样才能解决这个问题？我对 python 和 pygame 很陌生，所以我可能错过了一些明显的东西。我故意让AI速度更快。

import pygame, sys, random

pygame.init()

WIDTH = 1100
HEIGHT = 800

screen = pygame.display.set_mode((WIDTH, HEIGHT))

opponent = pygame.Rect(10, HEIGHT/2 - 50, 10, 100)
player = pygame.Rect(WIDTH - 20, HEIGHT/2 - 50, 10, 100)

ball = pygame.Rect(WIDTH/2 - 15 , HEIGHT/2 - 15,30,30)

clock = pygame.time.Clock()

player_speed = 0
opponent_speed = 15

ball_speed_x = 5
ball_speed_y = 5

score_player = 0
score_ai = 0
score = (score_ai, score_player)

while True:


    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP:
                player_speed -= 9
            if event.key == pygame.K_DOWN:
                player_speed += 9
        if event.type == pygame.KEYUP:
            if event.key == pygame.K_UP:
                player_speed += 9
            if event.key == pygame.K_DOWN:
                player_speed -= 9



#ball movement

    ball.x += ball_speed_x
    ball.y += ball_speed_y
    # ball colliding with ceiling/floor
    if ball.top <= 0:
        ball_speed_y *= -1

    if ball.bottom >= HEIGHT:
        ball_speed_y *= -1

    # if player misses ball
    if ball.left <= 0:
        ball = pygame.Rect(WIDTH/2 - 15 , HEIGHT/2 - 15,30,30)
        ball_speed_x = 5
        ball_speed_y = 5
        score_player += 1
        pygame.time.delay(1000)
        continue

    if ball.right >= WIDTH:
        ball = pygame.Rect(WIDTH / 2 - 15, HEIGHT / 2 - 15, 30, 30)
        ball_speed_x = 5
        ball_speed_y = 5
        score_ai += 1
        pygame.time.delay(1000)
        continue







    # hitting the ball

    if ball.colliderect(opponent):
        ball_speed_x = -10
        ball_speed_x *= -1
        ball_speed_y = -9
        ball_speed_y *= -1
    if ball.colliderect(player):
        ball_speed_x = 10
        ball_speed_x *= -1
        ball_speed_y = 9
        ball_speed_y *= -1





    # AI for opponent, if ball is higher, go up, if ball is lower, go down
    if ball.y <= opponent.centery:
        opponent.y -= opponent_speed
    if ball.y >= opponent.centery:
        opponent.y += opponent_speed



    # don't let the slides go too high
    player.y += player_speed
    if player.top <= 0:
        player.top = 0
    if player.bottom >= HEIGHT:
        player.bottom = HEIGHT
    if opponent.top <= 0:
        opponent.top = 0
    if opponent.bottom >= HEIGHT:
        opponent.bottom = HEIGHT

    screen.fill((0,0,0))
    pygame.draw.rect(screen, (0, 255, 0), player)
    pygame.draw.rect(screen, (255, 0, 0), opponent)
    pygame.draw.ellipse(screen, (255, 255, 255), ball)
    pygame.draw.aaline(screen, (0,0,255), (WIDTH/2, 0), (WIDTH/2, HEIGHT))

    pygame.display.update()
    clock.tick(60)

参见。当球击中球员时，需要沿x-axis反转速度，通过球拍限制球球的位置：

while True:
    # [...]

   if ball.colliderect(opponent):
        ball.left = opponent.right
        ball_speed_x *= -1
    if ball.colliderect(player):
        ball.right = player.left
        ball_speed_x *= -1

Simple pong: but the ball goes into the corner and bounces the wrong way and then it keeps cycling how can I fix this?
