python - 我怎样才能让列表中的每一项都有延迟？

Question

我正在尝试制作一个内存游戏，其中有四种颜色，您必须在程序不断向列表中添加 +1 的同时匹配模式。

现在我不知道如何让游戏显示模式。然后等待玩家输入以结束游戏或为图案添加另一种颜色。

这就是我能想到的:

def addlist():
    if playerpattern == pattern:
        pattern.append(random.randint(1, 4)) 

def listcheck():
    if playerpattern == pattern:
        for i in pattern:
            if i == 1:
                topleft.color = (255, 0, 0)
            else:
                topleft.color = (100, 0, 0)
            if i == 2:
                topright.color = (0, 0, 255)
            else:
                topright.color = (0, 0, 175)
            if i == 2:
                bottomleft.color = (0, 255, 0)
            else:
                bottomleft.color = (0, 175, 0)
            if i ==4:
                bottomright.color = (255, 255, 0)
            else:
                bottomright.color = (175, 175, 0)

pattern = []
playerpattern = []
playing = True

while playing:
    clock.tick(10)
    print(pattern)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            playing = False
        if event.type == MOUSEBUTTONDOWN:
            mouseclick()

    mousehover()
    addlist()
    listcheck()
    draw()

pygame.quit()

基本上，当游戏开始时，我希望游戏点亮图案 [0](4 个方 block 之一)。

然后当玩家正确显示 pattern[0]，然后延迟显示 pattern[1]，然后重复直到结束。感谢您的帮助

pygame 具有计时器功能 pygame.time.set_timer() .

定义一个事件id(7只是任意数字，你可以定义这个数字)

myEventID = pygame.USEREVENT+7

以一定的间隔时间启动计时器，例如1 秒(1000 毫秒)

pygame.time.set_timer(myEventID, 1000) # 1000 milliseconds interval

每次时间跨度结束时获取事件通知:

for event in pygame.event.get():

    if event.type == myEventID:
        # [...]

通过将 0 传递给毫秒参数来停止计时器:

pygame.time.set_timer(myEventID, 0)

添加一个游戏状态变量，表示游戏当前的状态，在定时器中修改这个变量。 state是一个整数，有特定的含义e.g.

gameState = 0
while playing: 

    for event in pygame.event.get():

        if event.type == myEventID:
            # change the game state - this is just an example
            if gameState == 0:
                gameState = 1 


    if gameState == 0:

        # do default

    elif gameState == 1:

        # do something else

    elif gameState == 2:

       # do something completely different

    else:

       # another case
