基于Roblox Talking NPC的聊天机器人输入hello崩溃的解决方法

错误原因分析 #

报错信息显示TypeError: can only concatenate str (not "int") to str，根源在于变量名冲突：

• 初始定义sys4 = 0作为记录"hello"输入次数的整数计数器
• 但在while循环内，执行sys4 = random.choice(["...", ...])将sys4重新赋值为字符串类型的回复内容
• 后续执行sys4 += 1时，试图把字符串和整数相加，触发类型错误

修复方案 #

1. 分离变量职责 #

将计数器变量和随机回复变量分开命名，避免类型覆盖：

• 保留sys4作为整数计数器
• 新增sys4_reply存储针对重复hello的随机回复内容
• 同理修复sys2的变量冲突问题，新增sys2_reply存储对应回复

2. 补充缺失的模块导入 #

代码中使用了time.sleep()但未导入time模块，需添加导入语句。

修改后的完整代码 #

import random
import time  # 补充缺失的time模块导入

print(" AI created by MThien \n")

sys = input(" [ System ]: My name is: ")

sys2 = 0  # 记录911呼叫次数的计数器
sys4 = 0  # 记录hello输入次数的计数器

while True:
    user  = input(" [ " + str(sys) + " ]: ")
    
    sys1 = random.choice(["Hello!", "Hello there", "Hello " + str(sys), "Sup!", "Howdy!", "Wassup!"])
    sys2_reply = random.choice(["Wrong number, sorry.", "Apologize, my visitor is just having a mental breakdown."])
    sys3 = random.choice(["What?", "?", "Sorry?", "I don't understand", "I don't get it.", "Sry my English is bad.", "Sry my IQ is still low."])
    sys4_reply = random.choice(["...", "Stop it.", "You've already said hello to me several times.", "That's enough for greeting me."])

    if user == "hello":
        print(" [ AI ]: " + str(sys1))
        sys4 += 1
        if sys4 >= 5:
            print(" [ AI ]: "+ sys4_reply)
    elif user == "/call":
        print(" [ Telephone ] : *dialing*")
        time.sleep(2)
        print(" [ Telephone ] : The number you're calling isn't registered.")
        time.sleep(1)
        print(" [ Telephone ] : *call ended*")
    elif user == "/call 911":
        print(" [ Telephone ] : *dialing*")
        time.sleep(2)
        print(" [ Telephone ] : 911, what's your emergency?")
        time.sleep(1)
        print(" [ AI ]: "+ str(sys1))
        time.sleep(1)
        print(" [ Telephone ] : *call ended*")
        sys2 += 1
        if sys2 == 3:
            time.sleep(3)
            print(" [ FBI ] : FBI, OPEN UP!")
            time.sleep(5)
            print(" [ System ]: You were kicked from this experience: You got arrested!")
            break
    else:
        print(" [ AI ]: " + str(sys3))

关键修改点说明 #

• 拆分了计数器变量与回复内容变量，确保计数器始终为整数类型，避免类型冲突
• 补充import time语句，解决time.sleep()未定义的报错
• 修正了原代码中sys2同样存在的变量覆盖问题
