有没有人能帮我写一个切换按钮的pygame代码？

Question

def box_button(x,y, colour, action=None):
    toggle = False
    pos = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()

    if click[0] == 1 and (x + 10) + 30 > pos[0] > (x + 10) and (y + 10) + 30 > pos[1] > (y + 10):
        if toggle == True:
            toggle = False
            colour = red
        else:
            toggle = True
            colour = green
    pygame.draw.rect(window, white, (x, y, 50, 50))
    pygame.draw.rect(window, colour, (x + 10, y+10, 30, 30))
    return colour

有没有人能帮我把按钮从红色切换到绿色？每次我点击这个代码的按钮时，它就会变成绿色，但是当我松开点击的时候，它又变成了红色，我想让它永久保持绿色吗？谢谢

您必须实现MOUSEBUTTONDOWN事件。

获取主应用程序循环中的事件列表：

events = pygame.event.get()
for event in events:
    if event.type == pygame.QUIT:
        # [...]

向box_button添加一个events参数，并将事件列表传递给函数：

box_button(events, .....)

def box_button(events, x, y, colour, action=None):
    toggle = False

    for event in events:
        if event.type == pygame.MOUSEBUTTONDOWN:
            button_rect = pygame.Rect(x + 10, y+10, 30, 30)
            if event.button == 1 and button_rect.collidepoint(event.pos):
                toggle = not toggle
                colour = green if toggle else red

    pygame.draw.rect(window, white, (x, y, 50, 50))
    pygame.draw.rect(window, colour, (x + 10, y+10, 30, 30))
    return colour
