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,timepygame.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 += 1number = 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()
