pygame 添加的比它应该添加的多 [duplicate]

问：

我正在制作一个简单的游戏，但 pygame 无法正常工作。 代码如下：

import pygame
from sys import exit
from debug15 import debug15

pygame.init()
CROSIRCLE = 1


def layoutdraw():
    pygame.draw.line(screen, White, (233, 0), (233, 700), 7)
    pygame.draw.line(screen, White, (0, 233), (700, 233), 7)
    pygame.draw.line(screen, White, (467, 0), (467, 700), 7)
    pygame.draw.line(screen, White, (0, 467), (700, 467), 7)


def xoadder(x, y, determiner):
    if determiner == 1:
        screen.blit(CROSS, (x, y))
    if determiner == 2:
        screen.blit(CIRCLE, (x, y))


def xoadduserfo(x, y, z, d, a):
    global CROSIRCLE
    if x <= mx <= y and d <= my <= z and CROSIRCLE % 2 == 1 and event.type == pygame.MOUSEBUTTONDOWN:
        xoadder(x, d, 1)
        CROSIRCLE = CROSIRCLE + a


def xoadduserfe(x, y, d, z, a):
    global CROSIRCLE
    if x <= mx <= y and d <= my <= z and CROSIRCLE % 2 == 0 and event.type == pygame.MOUSEBUTTONDOWN:
        xoadder(x, d, 2)
        CROSIRCLE = CROSIRCLE + a


def xoadduser(x, y, z, d, a):
    global CROSIRCLE
    if x <= mx <= y and d <= my <= z and CROSIRCLE % 2 == 1 and event.type == pygame.MOUSEBUTTONDOWN:
        xoadder(x, d, 1)
        CROSIRCLE = CROSIRCLE + 1
    if x <= mx <= y and d <= my <= z and CROSIRCLE % 2 == 0 and event.type == pygame.MOUSEBUTTONDOWN:
        xoadder(x, d, 2)
        CROSIRCLE = CROSIRCLE + 1


screenHI = 700
screenWID = 700
screen = pygame.display.set_mode((screenWID, screenHI))
pygame.display.set_caption("TicTacToe")
clock = pygame.time.Clock()
screen.fill((132, 132, 132))

# vars
White = pygame.Color(255, 255, 255)

running = True
CROSS = pygame.image.load("CROSS.png")
CIRCLE = pygame.image.load("CIRCLE.png")
while running:
    for event in pygame.event.get():
        # quit
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
            CROSIRCLE = 1
        mx, my = pygame.mouse.get_pos()
        # cross and circle
        xoadduser(0, 233, 233, 0, 1)
    # layout
    layoutdraw()

    # debugging and updating display and fps
    debug15(CROSIRCLE, 0, 0, True)
    debug15(CROSIRCLE % 2, 0, 50, True)
    print(pygame.mouse.get_pos())
    clock.tick(60)
    pygame.display.update()

当我在该位置单击一次时，CROSIRCLE 值变为 3 xoaddusefo 和 xoadduserfe 函数是我正在试验的东西。 我希望它转到 2。 [请不要用井字游戏来回答这个问题。 只用我的问题的解决方案来回答这个问题。我把这个游戏做成一个编码练习。
