Not sure if this is too improtant;

but this COULD be wrong, im not sure at all. Just posting this. If its not wrong, please tell me. I didnt know you could combine these...

term.clear() term.setCursorPos(1,1)

[Cranium]

This is great! I'm gonna try it now...

here is a link to a basic menu generator I made a few days ago, turns out it didn't help the guy asking for help but you are welcome to use and adapt it

http://www.computerc...-advanced-menu/

please read to the end of the thread though so you can get the correct version

Nice useful code, but a quick suggestion, it's generally good practice to name your variables something meaningful. Just because you know what they are, doesn't mean other people do!

But still, very useful code!

[KaoS]

yeah, I've made a much better one since then though: runs better and can run in any area of the screen with customizable delimiters etc

I feel quite stupid asking this, but where do I put this part of the code

local options={
"option1",
"option2",
"option3"
}
local n=CUI(options)
print(n)

into this?

function CUI(m)
n=1
l=#m
while true do
term.clear()
term.setCursorPos(1,2)
for i=1, l, 1 do
if i==n then print(i, " ["..m[i].."]") else print(i, " ", m[i]) end
end
print("Select a number[arrow up/arrow down]")
a, b= os.pullEventRaw()
if a == "key" then
if b==200 and n>1 then n=n-1 end
if b==208 and n<=l then n=n+1 end
if b==28 then break end
end
end
term.clear() term.setCursorPos(1,1)
return n
end

Because, when I put it just above it all, it gives an "attempt to call nil"-error at line

local n=CUI(options)

Put it below the function

How do I make a border for my menu? I tried asking in Ask a Pro forum section, and they said to come here.
Also, my options looke like this:
1
2
3
When I want them to look like this:
1 2 3
Any help?
Here's the code:

function clear()
term.clear()
term.setCursorPos(1,1)
end
function one()
sleep(.5)
clear()
print("Hello")
end
function two()
sleep(.5)
clear()
print("Hey")
end
function three()
sleep(.5)
clear()
print("Hi")
end
local menuOptions = {"1", "2", "3"}
local termX, termY = term.getSize()
local selected = 1
function centerText(text, termY)
term.setCursorPos(termX/2-#text/2,termY)
term.write(text)
return true
end
function start()
while true do
term.clear()
for i,v in ipairs(menuOptions) do
  if i == selected then
	   centerText("["..v.."]", i)
else
	centerText(v,i)
end
   end
   local id, key = os.pullEvent()
   if key == 208 and selected < #menuOptions then
	selected = selected + 1
   elseif key == 200 and selected > 1 then
	selected = selected - 1
   elseif key == 28 then
	return selected
   end
end
end
x = start()
print()
if selected == 1 then
one()
end
if selected == 2 then
two()
end
if selected == 3 then
three()
end

@EmTeaKay thanks, it works now.
I'm also trying to figure out how i get the options in one line. I didn't found any solutions yet...

[EmTeaKay]

Well, if you find a way to do it, would you please PM me how?

[KaoS]

I took a look at your code and made it put all the choices on the same line, it is still set to use the up and down arrow keys to navigate, that should be easy to change

[Bansheebandit]

Im trying to make a menu that highlights different options in my Nuclear Powerplants OS. Ive currently been using the simple menu that requests the user to type an option but think its time for an upgrade. Could you help me?

[KaoS]

sure, try making an option based menu like above, once you have that it is easy to upgrade. if you have problems let us know

[88theturbo]

Hmm. When I try to run it it says bios:337: [string "menu"] :17: 'then' expected
When I check it. there is a then... Can someone help?

[KaoS]

How did you know what codes were equivalent to the keys?

http://www.minecraft.../wiki/Key_Codes

You can also open up the lua prompt and do this

 while true do
     print(os.pullEvent())
 end

That's much quicker I think..

[DerDuden]

Thanks man really good work =)
