選項4退出而不程序做預期功能

Question

我在computercraft寫一個程序的Minecraft國防部，每當我嘗試選擇4退出程序而不做任何事情：

os.pullEvent = os.pullEventRaw 
while true do 
term.clear() 
term.setCursorPos(1,1) 
print ("Welcome to F-SecOS") 
print ("1)initialize") 
print ("2)shutdown") 
print ("3)power control") 
print ("4)rednet control") 

input = io.read() 



if input == "1" then 
term.clear() 
term.setCursorPos(1,1) 
print ("intitializing 10%") 
print ("|") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("initializing 25%") 
print("/") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("initializing 50%") 
print("--") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("initializing 75%") 
print(".\.") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("initializing 90%") 
print("|") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("initializing 100%") 
print("/") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("F_sec initialized") 
sleep(1) 
term.clear() 
term.setCursorPos(1,1) 
print("F_SecOS V1.8") 
break 
end 

if input == "2" then 
os.shutdown() 
end 

if input == "4" then 
break 
    end 

if input == "3" then 
while true do 
term.clear() 
term.setCursorPos(1,1) 
print("1)open outer door") 
print("2)close outer door") 
print("3)open inner door") 
print("4)close inner door") 
print("5)open middle door") 
print("6)close middle door") 
print("q)exit") 
CI = io.read() 
if CI == "1" then 
    rs.setOutput("left",true) 
    end 

if CI == "2" then 
    rs.setOutput("left",false) 
    end 

if CI == "3" then 
    rs.setOutput("right",true) 
    end 

if CI == "4" then 
    rs.setOutput("right",false) 
    end 

if CI == "5" then 
    rs.setOutput("bottom",true) 
    end 

if CI == "6" then 
    rs.setOutput("bottom",false) 
    end 



if CI == "Q" or CI == "q" then 
    break 
    end 


    if input == "4" then 
term.clear() 
term.setCursorPos(1,1) 
print ("1)open ports") 
print ("2)close ports") 
print ("3)send message") 
print ("4)unused function") 
print ("5)unused function") 
print ("q)exit") 
RI = io.read() 


    if RI == "1" then 
    rednet.open ("top") 
    end 

    if RI == "2" then 
    rednet.close ("top") 
    end 

    if RI == "q" or RI == "Q" then 
    end 
    end 
end 
end 
end 

問題是紅網控制是不工作我輸入4，程序結束時沒有做任何事情沒有清除屏幕或打印文本，我試過我知道的一切來修復它但同樣的問題不斷髮生或我得到一個錯誤信息

順便說一下，在rednet controll中，沒有一個真正的做法是因爲引發了一整套新問題

你在中間這一大塊代碼：

if input == "4" then 
break 
    end 

輸入2和3之間，所以它在這裏捕捉輸入和停止它得到的代碼的末尾，你也有另外if input == "4"前與你想要做的事情的實際邏輯。
