That is my program(credit to rondouglas) and I was wondering how to add a title above the menu.

In the picture below, above Open Stairs I wish to have a title but I can't figure out how to do it.
Thank you to whoever can help! />

in

function main()
		while running do
				term.clear()
				term.setCursorPos(1,1) -- added
				print(title) --added
				term.setCursorPos(1,2)
				printMenu(mainMenu)
				event, key = os.pullEvent("key")
				onKeyPressed(key, mainMenu)
		end
end

Marked the added lines. then at the top you can assign a variable to the string you want and voila!

function main()
  while running do
	term.clear()
	term.setCursorPos(1,1)	-- << These two lines
	print("Your Title Here")  -- <<  
	term.setCursorPos(1,2)
	printMenu(mainMenu)
	event, key = os.pullEvent("key")
	onKeyPressed(key, mainMenu)
  end
end

Just one more thing, how would I center the menu and add another line of text on the other side of the screen from the title?
I found out how to center just text but I can't seem to get it working with the menu.

You probably will have to use setCursorPos(x,y)

[Doyle3694]

I don't think I followed the turns there, what exactly are you trying to do? Make another text on the other side but at the same line as the title?

I figured out how to center the menu but I still need help with this.

Help with?

Btw, did you center with term.setCursorPos() or another way, if another way, how do you do it? />

Where it says "TEXT HERE!@" in the picture I wish to do it in computercraft.

and I found this function on google lol and I just added it to where the script prints the menu.

local cPrint = function(text)
	    local x2,y2 = term.getCursorPos()
	    local x,y = term.getSize()
	    term.setCursorPos(math.ceil((x / 2) - (text:len() / 2)), y2)
	   
	    print(text)
end

function printMenu(menu)
for i = 1, #menu do
  if i == selectedItem then
   cPrint("[ "..menu[i].text.." ]")
  else
   cPrint(""..menu[i].text)
  end
end
end

I got it now, think I know how to do it:

function printEnd(text, y)
x = 49-#text
term.setCursorPos(x,y)
write(text)
end

Is my basic idea. going to go test some stuff with it now.

EDIT: It works! />

instead of a constant 49, use x = term.getSize() - #text
Note that getSize() returns x and y, but the y is ignored since it has nowhere to put it.

no because this is for a computer and a computer can have 51 characters on 1 line. this is the eaisets and msot simple way to do it. gives 3 blanksteps free space too.

I'm still having trouble adding that into the program ^.^

[Doyle3694]

just add this function at the top or something, and then call the function after the 2 lines we added before, with the y as 1 and text as whatever you want to print there
