基于Pygame的打字游戏用户输入无响应问题修复请求

问题描述

我正在开发一款打字游戏，通关条件为用户输入指定提示文本且打字速度≥35WPM。先完成了控制台运行版本，后续基于Pygame开发GUI版本，但GUI版本中用户输入文本后，代码未执行文本匹配与通关判断逻辑。我怀疑是if user_text == displayprompt:判断失效，尝试调整缩进、用列表存储字符对比等方法仍未解决，请求修复代码错误。

控制台版本代码

from time import time

def typingErrors(prompt):
    global iwords

    words = prompt.split()
    errors = 0

    for i in range(len(iwords)):
        if i in (0, len(iwords)-1):
            if iwords[i] == words[i]:
                continue
            else:
                errors +=1
        else:
            if iwords[i] == words[i]:
                if (iwords[i+1] == words[i+1]) & (iwords[i-1] == words[i-1]):
                    continue
                else:
                    errors += 1
            else:
                errors += 1
    return errors

def typingSpeed(iprompt, stime, etime):
    global time
    global iwords

    iwords = iprompt.split()
    twords = len(iwords)
    speed = twords / time

    return speed

def timeElapsed(stime, etime):
    time = etime - stime

    return time

def GeneratePrompt():
    with open(r"C:\Users\adarshrsm\Desktop\prompts.txt", 'r') as file:
        prompts=file.readlines()
        for i in prompts:
            if len(i)>=10 and len(i)<30:
                try:
                    index = randint(0,(len(prompts)))
                    finalprompt=prompts[index]
                except IndexError:
                    GeneratePrompt()
    return finalprompt


if __name__ == '__main__':
    #prompt = input("Enter Prompt: ")
    prompt=GeneratePrompt()
    print("Type this to open the chest:- '", prompt, "'")
    input("press ENTER when you are ready!")
    stime = time()
    iprompt = input()
    etime = time()
    time = round(timeElapsed(stime, etime), 2)
    speed = typingSpeed(iprompt, stime, etime)
    errors = typingErrors(prompt)
    accuracy = ((len(iwords)-errors)/len(iwords))*100
    wpm = round(speed,2)*60

    if accuracy == 100 and wpm >= 35:
        print("You have passed")
    else:
        print("You have failed")

问题分析与修复代码

核心问题点

事件队列重复处理：主循环中存在两个pygame.event.get()调用，第一个会取走所有QUIT事件，第二个可能无法获取完整的键盘输入事件，导致stime未正确记录、用户输入不完整。
提示文本换行符问题：readlines()读取的每行文本末尾包含\n换行符，用户输入不会包含该字符，直接对比永远不相等。
通关逻辑缩进错误：胜利/失败的判断逻辑缩进错误，导致失败分支永远不会执行；结果文本渲染仅执行一次，无法显示动画效果。
未初始化计时变量：若用户未按Enter就输入文本，stime未定义会引发报错。
提示文本生成逻辑缺陷：原函数可能选中不符合长度要求的文本，递归调用未返回结果。

关键修改说明

合并事件处理：将所有事件处理放在一个for event in pygame.event.get()循环中，确保所有输入事件被正确捕获。
处理换行符：在GeneratePrompt中用rstrip('\n')去掉文本末尾的换行符，同时过滤掉空行和不符合长度的文本。
修复计时逻辑：初始化stime为None，仅在第一次按Enter时开始计时，避免未计时就触发判断。
重构结果渲染：将结果动画逻辑移到主循环中，确保每一帧都更新渲染状态，显示完整的打字动画。
变量名冲突修复：将原speed变量重命名为text_speed，避免和打字速度计算的speed变量冲突。
优化提示文本生成：先过滤有效提示再随机选择，避免选中不符合要求的文本，同时移除无效的递归调用。
