How would you go about centering something in a computer eg:

  print ("center these words")

How would you center the words in the middle of the computer screen?

i think theres something in textutils API that can help you with this!

I am working on a script/API myself :/
I was just wondering if there is some standard lua code that i can use rather than installing a secondary API.

textutils is in LUA.

Come on, this is some pretty simple maths

OK, here's a function that figures out what X coordinate to print a string at so that it's centred.

function findCentre(str)
    local centreX = term.getSize()
    centreX = (centreX - #str) / 2
    if centreX > 0 then
        return centreX+1 -- This +1 is not necessary, it's personal preference.
    else
        return 1
    end
end

Can you figure out how to display your string AT that X coordinate? HINT: http://computercraft...rm.setCursorPos

Note: A string with an even number of characters can't really be centred properly...this MAY set off your OCD as it did mine.

Take a look at my some GUI functions I made.

If you don't understand what the functions do just pm me or ask here

With my funtions just do..

shell.run("GUI")
cPrint ("center these words")

Note the shell cmd may vary...

local function writeC(string)
	local tX, tY = term.getSize()
	local b = string.len(string) / 2
	local x = (tX / 2) - b
	local y = tY / 2
	term.setCursorPos(x, y)
	write(string)
end

This function prints any string in the center of the screen.
