如何创建跳过功能pygame？

Question

我正在尝试在pygame中创建一种方法，让玩家只需按“转义”即可跳过教程阶段。但是，使用以下命令时，似乎无法正常工作：

                for event in pygame.event.get():
                    if event.type == pygame.K_ESCAPE:
                        brek2 = True
                for event in pygame.event.get():
                    if event.type == pygame.QUIT:
                        run = False
                        run2 = False
                        brek = True
                if brek or brek2:
                    break
                pygame.time.delay(1000)
            if brek:
                break

如果需要，这里是教程阶段的完整循环：

        while run2:
                # intro sequence
                pygame.event.pump()
                fade(screen_width, screen_height, BLACK)
                fade(screen_width, screen_height, WHITE)
                techi = pygame.transform.scale(pygame.image.load("Techi-Joe.gif"), (75, 75))
                bg = pygame.Surface((screen_width, screen_height))
                bg.fill(WHITE)
                win.blit(pygame.transform.scale(bg, (screen_width, screen_height)), (0, 0))
                win.blit(techi, (100, 600))
                pygame.display.update()
                for event in pygame.event.get():
                    if event.type == pygame.QUIT:
                        run = False
                        run2 = False
                pygame.time.delay(1000)
                brek2 = False
                presss = 1
                brek = False
                techi_bubble = pygame.transform.scale(pygame.image.load("techi_speech_bubble.png"), (700, 350))
                techi_font = pygame.font.Font('Consolas.ttf', 25)
                for a in range(len(techi_says)):
                    win.blit(pygame.transform.scale(bg, (screen_width, screen_height)), (0, 0))
                    win.blit(techi_bubble, (175, 300))
                    win.blit(techi, (100, 600))
                    writeLikeCode(techi_says[a], 235, 350, techi_font, 20)
                    for event in pygame.event.get():
                        if event.type == pygame.K_ESCAPE:
                            brek2 = True
                    for event in pygame.event.get():
                        if event.type == pygame.QUIT:
                            run = False
                            run2 = False
                            brek = True
                    if brek or brek2:
                        break
                    pygame.time.delay(1000)
                if brek:
                    break

这里有一些附加代码，称为函数writeLikeCode：

techi_says = ["Hello, User!", "My name is Techi-Joe.", "I'm a programmer,", "and this is my first game:",
          "Dunk the Chief!", "in Dunk the Chief,", "your main objective", "is to dunk any US president", "you choose",
          "in a cold tub of water!", "yay!"]


# writeLikeCode function
def writeLikeCode(string, xpos, ypos, font, fontsize):
    for x in range(len(string)):
        lstring = split(string)
        text = font.render(lstring[x], 1, GREEN)
        win.blit(text, (xpos + (x * fontsize), ypos))
        pygame.time.delay(50)
        pygame.display.update()

这是分割功能：

def split(string):
    return [char for char in string]

pygame.event.get()不仅获取事件，还从事件队列中删除事件。如果您连续两次调用pygame.event.get()，则第一个调用将检索事件，但是第二个调用将返回一个空列表。

pygame.event.get()

如果事件在

for event in pygame.event.get(): # returns the list of events
   # [...]
for event in pygame.event.get(): # returns empty list
   # [...]

的两次调用之间发生，则该事件将作为第二次调用被接收。但这将是一种罕见的情况。

pygame.event.get()不是事件类型（请参见pygame.K_ESCAPE），它是键，请参见（pygame.event）。如果要检测是否按下了ESC，则必须检测pygame.event事件并评估pygame.key属性是否为pygame.key。例如：

KEYDOWN
