Hello my name is Dcleondc and im here to show you some functions/code that can help you make your next GUI.

if you are using these functions in your code make sure you put this code at the top


x, y = term.getSize()

Print Center-This function does just what it says, it will print the text that you pass it in the center of the screen
Usage-

 printC("Put any text here", and put what line you want it on here)

Code

Spoiler


function printC( text, ypos )
  term.setCursorPos(x/2 - #text/2, ypos)
  term.write(text)
end

Print Right- This function prints the text that you pass it in the center of the right section of the screen.
Usage-

 printR("Put any text here", and put what line you want it on here)

Code

Spoiler


function printR( text, ypos )
	xpos1 = x/2
	xpos2 = xpos1/2
	xpos3 = xpos2+xpos1
	xpos = xpos3-#text/2
	term.setCursorPos(xpos,ypos)
	term.write(text)
end

Print Left- This function prints the text that you pass it in the center of the left section of the screen.
Usage-

 printL("Put any text here", and put what line you want it on here)

Code

Spoiler


function printL( text, ypos )
	xpos1 = x/2
	xpos2 = xpos1/2
	xpos = xpos2 - #text/2
	term.setCursorPos(xpos,ypos)
	term.write(text)
end

Print menu- this function will print a border around screen.
Usage-

 menu(x,y)

Code

Spoiler


function menu(x1,y1)
	clear()
	for i=1, x1-1 do
		setPos(i,1)
		write("#")
	end
	for i=1, x1-1 do
		setPos(i,y1)
		write("#")
	end
	for i=1, y1-1 do
		setPos(1,i)
		write("#")
	end
	for i=1, y1-1 do
		setPos(x-1,i)
		write("#")
	end
end

setPos - faster the typing out term.setCursorPos(x,y)
usage- setPos(x,y)
code

Spoiler


function setPos(x,y)
  setCursorPos(x,y)
end

~~Your right print function is a bit weird, you don't need all the extra info.~~
Nvm
Good job, I still don't get the printR function though.
Print right of the center of the screen?

~~Where does the variable x come from?~~ ← Ignore this, I was just being derpy…

And in your printR() function you could just do

function printR( text, ypos )
	xpos = (x/2+(x/2)/2)-#text/2
	term.setCursorPos(xpos, ypos)
	term.write(text)
end

Or you know, get rid of the xpos variable entirely

function printR( text, ypos )
	term.setCursorPos((x/2+(x/2)/2)-#text/2, ypos)
	term.write(text)
end

EDIT: Also what is your setPos() function?
Either you misspelled term.setCursorPos() or you got a function like this

function setPos(x,y)
	term.setCursorPos(x,y)
end

Or if you go a bit more fancy like this

function setPos(x,y)
	x = tonumber(x)
	y = tonumber(y)
	if not x then x = 1 end
	if not y then y = 1 end
	term.setCursorPos(x,y)
end

Var x comes from the second sentence.
