Just mess around with:


local w,h = term.getSize()
local text = "SomeRandomString"
term.setCursorPos(w-20,h-10)
print(text)
term.setCursorPos(1,1)

Change how much it's taking off of the width and height until you get it centered.

It's easier to take the lenght of the screen to make it always center, so you don't have to try and change the value until it gets centered.
Try something like this:


function PrintCentered(sText)
    local w, h = term.getSize()
    local x, y = term.getCursorPos()
    x = math.max(math.floor((w / 2) - (#sText / 2)), 0)
    term.setCursorPos(x, y)
    print(sText)
end

This prints the text centered, but only the first line. So if you give it a string longer than the screen width, it prints like the normal print.

Try something like this:

	x = math.max(math.floor((w / 2) - (#sText / 2)), 0)
	term.setCursorPos(x, y)
	print(sText)
end

here is what i have so far


local function PrintCenter(msg)
local msgLen = string.len(msg)
local screenWidth,_ = term.getSize()
local xCoords = tonumber(math.ceil((screenWidth / 2) - (msgLen / 2)))
local _,termY = term.getCursorPos()
term.setCursorPos(xCoords,termY)
print(msg)
return xCoords
end

You can already create this yourself, so it is moot implementing it in an API.

dont worry i made the API :P/>/>
Heres the api file
(Just add this to a txt document named center and than remove the .txt and place in .minecraft/mods/computercraft/lua/apis and on computers use center.PrintCenter " " In your code)

CODE


function PrintCenter(msg)
msgLen = string.len(msg)
screenWidth,_ = term.getSize()
xCoords = tonumber(math.ceil((screenWidth / 2) - (msgLen / 2)))
_,termY = term.getCursorPos()
term.setCursorPos(xCoords,termY)
print(msg)
return xCoords
end

Awsome code works great. Two questions how can have the print out move a bit to the left or right. Also how can I get this to show off a monitor try some things did not work.

Never mind I got it.

function PrintCentered(sText)
local w, h = mon.getSize()
local x, y = mon.getCursorPos()
x = math.max(math.floor((w / 2) - (#sText / 2)), 0)
mon.setCursorPos(x, y)
mon.write(sText)
end

Mods, now that this is solved, shouldn't it be moved to general or programs?

Or you could just do this


function printCen(msg)
  w, h = term.getSize()
  term.setCursorPos(w/2, h/2)
  write(msg)
end

Always prints in the center of the screen
If you want to print in the center of a line then


function printCen(msg, ycord)
  w, h = term.getSize()
  term.setCursorPos(w/2, ycord)
  write(msg)
end

If you'd actually tried either of those, you'd know they don't work properly as they always print the message to the right of the centre.
You should also have seen that this thread is 4 months old.
