pygame按钮单击

Question

我在pygame中制作了用于单击事件的按钮，但是存在问题。当我单击鼠标按钮并在按钮边界之间移动鼠标时，单击事件会重复发生。我只想单击一下，直到释放鼠标按钮。我怎样才能做到这一点？

import pygame,time

pygame.init()

x,y = (200,300)

pencere = pygame.display.set_mode((x,y))

pygame.display.set_caption("Click")

white = (255,255,255)

black = (0,0,0)

black2 = (30,30,30)

class Counter:

    count = 0

    def click(self):

        self.count += 1

number = Counter()

def text_objects(text, font, color):

    textSurface = font.render(text, True, color)

    return textSurface, textSurface.get_rect()

def button(msg,x,y,w,h,c,ic,action=None):

    mouse = pygame.mouse.get_pos()

    click = pygame.mouse.get_pressed()

    pygame.draw.rect(pencere, c,(x,y,w,h))

    smallText = pygame.font.Font("freesansbold.ttf",20)

    textSurf, textRect = text_objects(msg, smallText, white)

    textRect.center = ( (x+(w/2)), (y+(h/2)) )

    pencere.blit(textSurf, textRect)

    if x+w > mouse[0] > x and y+h > mouse[1] > y:

        pygame.draw.rect(pencere, ic,(x,y,w,h))

        if click[0] == 1 != None:

            action()

        smallText = pygame.font.Font("freesansbold.ttf",20)

        textSurf, textRect = text_objects(msg, smallText, white)

        textRect.center = ( (x+(w/2)), (y+(h/2)) )

        pencere.blit(textSurf, textRect)

def loop():

    cikis = False

    while not cikis:

        for event in pygame.event.get():

            if event.type == pygame.QUIT:

                cikis = True

                pygame.quit()

                quit()

            pencere.fill(white)

            smallText = pygame.font.Font("freesansbold.ttf",50)

            textSurf, textRect = text_objects(str(number.count), smallText, black)

            textRect.center = ((x/2)), (30)

            pencere.blit(textSurf, textRect)

            button("Click",0,100,200,200,black,black2,number.click)

            pygame.display.update()

loop()

pygame.quit()

quit()
