Question

我一直在和Pygame合作，我遇到了这个问题。我制作了2个动画列表。一个叫rightImages，其中包含我的角色走向右边的图像，还有一个叫做leftImages的图像是相反的。当我按下D键（我的程序的控件是A，左边是D，右边等）时，动画可以正常工作，但是当我按住它时，动画不会运行。希望你理解，如果你不理解请运行程序，那么也许你会得到我说的。这是我的代码：

def Main():


    x_change = 0
    y_change = 0
    x = 400
    y = 400
    counter = 0
    counter2 = 0
    player = pygame.image.load('knight_left.png')

    while True:

        rightImages = ['knight_right.png','knight_right1.png','knight_right2.png']
        leftImages =['knight_left.png', 'knight_left1.png', 'knight_left2.png']
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_d:
                    x_change += 5
                    counter += 1
                    if counter >= len(rightImages):
                        counter = 0
                    player = pygame.image.load(rightImages[counter])

                elif event.key == pygame.K_a:
                    x_change -= 5
                    counter2 += 1
                    if counter2 >= len(leftImages):
                        counter2 = 0
                    player = pygame.image.load(leftImages[counter2])
                elif event.key == pygame.K_w:
                    y_change -= 5
                elif event.key == pygame.K_s:
                    y_change += 5
            elif event.type == pygame.KEYUP:
                x_change = 0
                y_change = 0


        x = x+x_change
        y = y+y_change

        gameDisplay.fill(white)
        gameDisplay.blit(player,(x,y))
        pygame.display.update()

        clock.tick(30)

Main()

这是在向右走时通过动画循环运行的代码。

counter += 1
if counter >= len(rightImages):
    counter = 0
player = pygame.image.load(rightImages[counter])

这是向左走的时候。

counter2 += 1
if counter2 >= len(rightImages):
    counter2 = 0
player = pygame.image.load(rightImages[counter2])

如果你能告诉我如何循环播放动画列表，即使按下按键也很棒！

请尝试以下代码。

def Main():
    x = 400
    y = 400
    counter = 0
    counter2 = 0
    player = pygame.image.load('knight_left.png')
    rightImages = ['knight_right.png','knight_right1.png','knight_right2.png']
    leftImages =['knight_left.png', 'knight_left1.png', 'knight_left2.png']
    while True:
        x_change = 0
        y_change = 0
        keys = pygame.key.get_pressed()  #checking pressed keys
        if keys[pygame.K_d]:
            x_change += 5
            counter += 1
            if counter >= len(rightImages):
                counter = 0
            player = pygame.image.load(rightImages[counter])
        if keys[pygame.K_a]:
            x_change -= 5
            counter2 += 1
            if counter2 >= len(leftImages):
                counter2 = 0
            player = pygame.image.load(leftImages[counter2])


        x = x+x_change

        gameDisplay.fill(white)
        gameDisplay.blit(player,(x,y))
        pygame.display.update()

        clock.tick(30)

Main()

我通常会做类似的事情：首先在主循环开始之前加载图像，因为从硬盘读取速度很慢。

将当前选定的图像分配给变量active_images，如果玩家按下某个键，则将其换出，例如active_images = right_images。

在主循环中，你只需检查玩家是否移动然后递增counter（或timer变量）并将当前图像分配给player变量：{ {1}}。

player = active_images[counter]

按住按钮时动画循环不起作用
