Python Pygame-按钮渲染问题

基本上，我想用pygame创建一个按钮并在上面写下文本，我成功了

但当光标位于按钮上时，最后一个按钮（名为LeadboardButton）不会将图像更改为“/image/mouseOnButton.png”

我真想知道为什么会这样。按钮的其余部分很好

FPS = 60
clock = pygame.time.Clock()
screen = pygame.display.set_mode((800, 700))
screen.fill((255, 255, 255))

pygame.init()

class Button():
    def __init__(self, msg, font, x , y, w, h, color):
        self.msg = msg
        self.font = font
        self.x = x
        self.y = y
        self.w = w
        self.h = h
        self.color = color

    def createButton(self):
        (mouseX, mouseY) = pygame.mouse.get_pos()
        if((mouseX >= self.x and mouseY <= self.x + self.w) and (mouseY >= self.y and mouseY <= self.y + self.h)):
            button = pygame.image.load("./image/mouseOnButton.png")
        else:
            button = pygame.image.load("./image/button.png")
        screen.blit(button, (self.x, self.y))
        text = pygame.font.SysFont(self.font, 32)
        textSurface = text.render(self.msg.encode("utf-8"), True, self.color)
        screen.blit(textSurface, (self.x + self.w / len(self.msg), self.y + self.h / 2))

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:

            if(event.key == pygame.K_F4 and pygame.KMOD_ALT):
                sys.exit()

    localButton = Button("Local Play", "./font/NanumSquareRoundEB.ttf", 325, 200, 150, 75, (255, 255, 255)).createButton()

    howtoButton = Button("How to Play", "./font/NanumSquareRoundEB.ttf", 325, 450, 150, 75, (255, 255, 255)).createButton()
    leaderboardButton = Button("Leaderboard", "./font/NanumSquareRoundEB.ttf", 325, 575, 150, 75, (255, 255, 255)).createButton()
    pygame.display.update()
    clock.tick(FPS)

我能理解你的代码，但我仍然不知道问题出在哪里。这是因为优化还是什么？哦，看起来这只是

（mouseX>=self.x和mouseY我太笨了…谢谢你的好意和额外的提示！我能理解你的代码，但我仍然不知道问题出在哪里。这是因为优化还是什么？哦，这似乎只是
