我正在为 Computercraft 开发 Windows 8 模拟操作系统,但我的登录系统无法正常工作。在过去的一个小时左右,我一直在试图弄清楚,这真的很令人沮丧。
这是登录代码:
-- Log-in and User Definition Service
--- Variables
userExists = fs.exists("/Users/.config/userConfig.cfg")
termx, termy = term.getSize()
halfx = math.floor(termx*0.5)
halfy = math.floor(termy*0.5)
prompt = "Welcome"
uprompt = "Username: "
pprompt = "Password: "
userConfig = fs.open("/Users/.config/userConfig.cfg", "r")
edituserConfig = fs.open("/Users/.config/userConfig.cfg", "w")
--- Functions
function login(user)
if user == "admin" then
term.setCursorPos(1,1)
term.setTextColor(256)
print (user)
elseif user == "guest" then
print (user)
else
print ("nil")
end
end
function userCheck()
if userExists == true then
term.clear()
term.setBackgroundColor(8)
term.setCursorPos(halfx-0.5*#prompt, halfy - 4)
term.clear()
print (prompt)
term.setCursorPos((halfx-#uprompt), (halfy - 2))
write (uprompt)
term.setCursorPos((halfx-#uprompt), (halfy - 1))
write (pprompt)
term.setCursorPos((halfx), (halfy - 2))
upin = read()
term.setCursorPos((halfx), (halfy - 1))
ppin = read("*")
if upin == userConfig.readLine(21) and ppin == userConfig.readLine(24) then
print ("ADMIN")
elseif upin == userConfig.readLine(33) and ppin == userConfig.readLine(36) then
login("guest")
end
elseif userExists == false then
elseif userExists == nil then
end
end
--- Main
userCheck()
用户配置.cfg:
