Question

我试图选择键盘输入1和2来选择图库1或2，这是要在屏幕上加载的图像列表它与一个具有此代码的图库一起工作正常

import pygame


WIDTH = 1366
HEIGHT = 768

pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT), pygame.NOFRAME)
clock = pygame.time.Clock()  # Needed to limit the frame rate.
pygame.display.set_caption('Katso')
# Put the images into a list.
images = [
    pygame.image.load('assets/download.png').convert(),
    pygame.image.load('assets/mickey.jpg').convert(),
    pygame.image.load('assets/cat.jpg').convert(),
    pygame.image.load('assets/flavours.jpg').convert(),
    pygame.image.load('assets/hallway.jpg').convert(),
    ]
image_index = 0
image = images[image_index]  # The current image.

x = 0  # x coordnate of image
y = 0  # y coordinate of image

running = True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                image_index -= 1  # Decrement the index.
            elif event.key == pygame.K_RIGHT:
                image_index += 1  # Increment the index.

            # Keep the index in the valid range.
            image_index %= len(images)
            # Switch the image.
            image = images[image_index]

    screen.fill((30, 30, 30))
    # Blit the current image.
    screen.blit(image, (x, y))

    pygame.display.update()
    clock.tick(30)  # Limit the frame rate to 30 fps.

pygame.quit()

但是尝试添加更多列表并被选中只是没有用。我尝试在不同的循环和相同的循环中选择图库，但没有任何工作。

import pygame


WIDTH = 1366
HEIGHT = 768

pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT), pygame.NOFRAME)
clock = pygame.time.Clock()  # Needed to limit the frame rate.
pygame.display.set_caption('Katso')
# Put the images into a list.
gallery1 = [
    pygame.image.load('assets/download.png').convert(),
    pygame.image.load('assets/mickey.jpg').convert(),
    pygame.image.load('assets/cat.jpg').convert(),
    pygame.image.load('assets/flavours.jpg').convert(),
    pygame.image.load('assets/hallway.jpg').convert(),
    ]

gallery2 = [
    pygame.image.load('assets/adv.jpg').convert(),
    pygame.image.load('assets/star.jpg').convert(),
    pygame.image.load('assets/images.jpeg').convert(),
    pygame.image.load('assets/tile.png').convert(),
    ]

x = 0  # x coordnate of image
y = 0  # y coordinate of image

running = True
gallery = gallery1 #set the default gallery

image_index = 0
image = gallery[image_index]  # The current image.

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_1:
                gallery = gallery1
            elif event.key == pygame.K_2:
                gallery = gallery2            
            elif event.key == pygame.K_LEFT:
                image_index -= 1  # Decrement the index.
            elif event.key == pygame.K_RIGHT:
                image_index += 1  # Increment the index.

            # Keep the index in the valid range.
            image_index %= len(gallery)
            # Switch the image.
            image = gallery[image_index]

    screen.fill((30, 30, 30))
    # Blit the current image.
    screen.blit(image, (x, y))

    pygame.display.update()
    clock.tick(30)  # Limit the frame rate to 30 fps.

pygame.quit()

我在发布问题后终于开始工作了我很高兴看到任何暗示或想法来改善该计划的运作方式。

import pygame


WIDTH = 1366
HEIGHT = 768

pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT), pygame.NOFRAME)
clock = pygame.time.Clock()  # Needed to limit the frame rate.
pygame.display.set_caption('Katso')
# Put the images into a list.
gallery1 = [
    pygame.image.load('assets/download.png').convert(),
    pygame.image.load('assets/mickey.jpg').convert(),
    pygame.image.load('assets/cat.jpg').convert(),
    pygame.image.load('assets/flavours.jpg').convert(),
    pygame.image.load('assets/hallway.jpg').convert(),
    ]

gallery2 = [
    pygame.image.load('assets/adv.jpg').convert(),
    pygame.image.load('assets/star.jpg').convert(),
    pygame.image.load('assets/images.jpeg').convert(),
    pygame.image.load('assets/tile.png').convert(),
    ]

x = 0  # x coordnate of image
y = 0  # y coordinate of image

running = True
gallery = gallery1 #set the default gallery

image_index = 0
image = gallery[image_index]  # The current image.

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_1:
                gallery = gallery1
            elif event.key == pygame.K_2:
                gallery = gallery2                      
            elif event.key == pygame.K_LEFT:
                image_index -= 1  # Decrement the index.
            elif event.key == pygame.K_RIGHT:
                image_index += 1  # Increment the index.

            # Keep the index in the valid range.
            image_index %= len(gallery)
            # Switch the image.
            image = gallery[image_index]

    screen.fill((30, 30, 30))
    # Blit the current image.
    screen.blit(image, (x, y))

    pygame.display.update()
    clock.tick(30)  # Limit the frame rate to 30 fps.

pygame.quit()
