我一直在重复代码，想知道是否有办法简化这些 if 语句

Question

我创建的代码在 pygame 中用于突出显示我悬停在上面的按钮，当点击时将触发它们相应的功能

if singleplayer_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), singleplayer_button)
    WIN.blit(singleplayer_button_text, (295, 400))
    if click:
        singleplayer()
else:
    pygame.draw.rect(WIN, RED, singleplayer_button)
    WIN.blit(singleplayer_button_text, (295, 400))

if multiplayer_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), multiplayer_button)
    WIN.blit(multiplayer_button_text, (727, 400))
    if click:
        multiplayer1()
else:
    pygame.draw.rect(WIN, RED, multiplayer_button)
    WIN.blit(multiplayer_button_text, (727, 400))

if leaderboard_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), leaderboard_button)
    WIN.blit(leaderboard_button_text, (291, 550))
    if click:
        leaderboard()
else:
    pygame.draw.rect(WIN, RED, leaderboard_button)
    WIN.blit(leaderboard_button_text, (291, 550))

if credit_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), credit_button)
    WIN.blit(credits_button_text, (774, 550))
    if click:
        credit()
else:
    pygame.draw.rect(WIN, RED, credit_button)
    WIN.blit(credits_button_text, (774, 550))

if register_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), register_button)
    WIN.blit(register_button_text, (300, 700))
    if click:
        register()
else:
    pygame.draw.rect(WIN, RED, register_button)
    WIN.blit(register_button_text, (300, 700))

if exit_button.collidepoint(mx, my):
    pygame.draw.rect(WIN, (180, 0, 0), exit_button)
    WIN.blit(exit_button_text, (737, 700))
    if click:
        exit_window()
else:
    pygame.draw.rect(WIN, RED, exit_button)
    WIN.blit(exit_button_text, (737, 700))

####_button 是一个矩形

####_button_text 是在矩形顶部 blitted 的文本

读一读 Classes。

创建 Button class:

class Button():
    def __init__(self, rect, text, action):
        self.rect = rect
        self.text = text
        self.action = action
    def draw(self, win):
        pygame.draw.rect(win, (180, 0, 0), self.rect)
        WIN.blit(self.text, self.text.get_rect(center = self.rect.center))
    def click(self, mx, my, click):
        if self.rect.collidepoint(mx, my) and click:
            self.action()

创建 Botton 个对象的列表：

buttons = [
    Button(singleplayer_button, singleplayer_button_text, singleplayer),
    Button(multiplayer_button,  multiplayer_button_text,  multiplayer1),
    Button(leaderboard_button,  leaderboard_button_text,  leaderboard),
    Button(credit_button,       credits_button_text,      credit),
    Button(register_button,     register_button_text,     register),
    Button(exit_button,         exit_button_text,         exit_window)
]

循环绘制按钮：

for button in buttons:
    button.draw(WIN)

在循环中进行点击检测：

for button in buttons:
    button.click(mx, my, click)

I'm continuously repeating code and wondering if there's a way to simplify these if statements

python
