Question

if语句没有意识到car1num和car2num正在改变，只是忽略了它们中断了汽车的切换和转向

在game\u loop（）下面的代码中，它说“car2num=2”和“car1num=1”，然后它说

    for event in pygame.event.get():
        if crashed == 0:
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RCTRL:
                    car2num += 1
                    if car2num == 4:
                        car2num = 1
                if event.key == pygame.K_LCTRL:
                    car1num += 1
                    if car1num == 4:
                        car1num = 1

因此，每次按RCRTL car2num都会上升，每次按LCRTL car1num都会上升，甚至更晚（对于car1num和car2num都有一个）

        if car2num == 1:
            car2IMG = pygame.image.load('textures\car1.png')
        if car2num == 2:
            car2IMG = pygame.image.load('textures\car2.png')
        if car2num == 3:
            car2IMG = pygame.image.load('textures\car3.png')

所以车的数量1/2num决定了车

但它将始终保持原来设置为“car2num=2”和“car1num=1”的汽车状态

谢谢你提前帮忙，也很抱歉没组织好
