如何在PyGame中每次显示新问题时保存用户输入至列表？

我是编程新手，花了两个月写这段PyGame代码。需求是：每次屏幕显示新问题时，把用户输入的user_text存入answers列表（比如3个问题对应答案列表是[1,4,3]）。但现在遇到三个问题：

• 列表为空，完全存不住输入
• 只能保存单个答案，没法存所有输入
• current_dialogue_index混乱，导致问题跳过

需要易懂的基础解决方案，之后要根据答案总分做后续逻辑。

原代码 #

#Dialogue
messages = ["Hello and welcome to Dr. Collins' office. (Press the 'Enter' key to continue).",
            "I presume you have an appointment with us today?",
            "To use our tele-health system click on the input box below when prompted.",
            "When the input box is green, you may begin to type your response.",
            "Now, please hold a moment. Dr. Collins will be with you shortly."
            ]
intro = ["Hello there, my name is Dr. Collins. What is your name?",
             "Hello",
             ]
questions =  ["On a scale of 1 to 5, 1 being not at all and 5 being all the time: Are you experiencing any pain?",
             "On a scale of 1 to 5, 1 being not at all and 5 being all the time: Have you ever contimplated suicide?",
             "On a scale of 1 to 5, 1 being not at all and 5 being all the time: Do you ever have trouble sleeping?",
             "On a scale of 1 to 5, 1 being not at all and 5 being all the time: Do you ever have trouble concentrating?",
             "On a scale of 1 to 5, 1 being not at all and 5 being all the time: Do you struggle with poor appetite or overeating?"
             ]

Final_Messages = ["Thank you for you time today.",
                  "I'm going to review your questions.",
                  "Your prescription will print shortly.",
                  "When you received your prescription, you may click the 'Finish' button."

解决方案 #

问题根源是答案保存时机错误+索引重复修改，以下是分步修正：

1. 声明全局answers列表

函数内默认会创建局部变量，导致外部的answers始终为空。在game_loop开头加：

global answers

2. 修复答案保存逻辑

只有在问题列表（questions）提交输入时，才把user_text加入answers，同时清空输入框准备下一题。

3. 移除重复的索引修改代码

原代码末尾的if active:块会额外累加current_dialogue_index，直接导致问题跳过，必须删掉。

修正后的回车事件核心逻辑

替换原代码中回车事件的处理部分：

if event.key == pygame.K_RETURN:
    if current_list == messages and current_dialogue_index == len(current_list) - 1:
        current_list = intro
        current_dialogue_index = 0
        doctor_mode = True
    elif current_list == intro and current_dialogue_index == len(current_list) - 1:
        current_list = questions
        current_dialogue_index = 0
    elif current_list == intro and current_dialogue_index == 0 and not save_name:
        name = user_text
        save_name = True
        user_text = ''  # 保存名字后清空输入
    elif current_list == questions:
        # 保存当前问题的答案
        answers.append(user_text)
        user_text = ''
        # 切换到下一题或结束问题环节
        if current_dialogue_index == len(current_list) - 1:
            current_list = Final_Messages
            current_dialogue_index = 0
        else:
            current_dialogue_index += 1
    elif current_list == Final_Messages and current_dialogue_index == len(current_list) - 1:
        screen.fill((0,0,0))
    else:
        current_dialogue_index += 1
        if current_dialogue_index >= len(current_list):
            done = True
            break

验证效果 #

• 每个问题提交后，answers会自动添加输入的数字，最终会得到完整的答案列表
• current_dialogue_index只会在正确时机+1，不会跳步
• 之后可以用sum(answers)计算总分，或遍历列表实现后续逻辑
