python - 在 pygame 上更新和显示图像

Question

我正在尝试在 pygame 中编写代码，使用语音识别和不同的图像。代码应按如下方式运行:用户将看到不同的动物图像，并且必须说出他们看到的是什么。之后，语音识别将获取用户的输入并将其转换为字符串，并将其与显示图像相关联的字符串进行比较。并判断答案是否正确，然后移动到另一张图片。

我现在遇到的困难是每次用户提供答案时上传和更新图像

Answer 1

创建图像列表，而不是文件名列表:

image_list = []
for filename in glob.glob('MG/*.jpg'):
    image_list.append(pygame.image.load(filename))

创建一个名称列表。名称列表必须对应于图像列表:

name_list = ['dog', 'cat', 'rat']

在 name_list 中找到与 text 匹配的元素的索引。有不同的方法可以做到这一点。参见 Finding the index of an item in a list .例如:

try:
    index = name_list.index(text)
except ValueError:
    index = -1

---

例子:

image_list = []
for filename in glob.glob('MG/*.jpg'):
    image_list.append(pygame.image.load(filename))

name_list = ['dog', 'cat', 'rat'] 

text = r.recognize_google(audio)

try:
    index = name_list.index(text)
except ValueError:
    index = -1

gameDisplay.fill(white)
if 0 <= index <= len(image_list): 
    gameDisplay.blit(image_list[index], (130,0))
pygame.display.update()

if index > 0:
    message_display('good job')
else:
    message_display('wrong')
