[SOLVED]Centering text to screen

Post by veethree » Fri Mar 09, 2012 6:13 am

Hey guys. quick question. Is it possible to center text displayed with love.graphics.print? I know the "formula" to center stuff to the screen but for that i'd need something that would return the width of said thing. And i've looked through the wiki and didn't find any function or something that would do that. Perhaps there is one, But i'm just blind/stupid.
Thanks in advance.

You could use a fixed width font which would allow you to calculate the width easily

Don't know if this is the formula you referring but can't you use printf instead of print? Only need to know the screen width (so usually a fixed var) and not always getting object/text size
w = love.graphics.getWidth()
love.graphics.printf(text,0,0,w)

I completely forgot about printf, Haven't fully tested it, But it appears to work if i do what you did and set the alignment to "center". Thanks :D


Oh and the formula i was referring to is setting the X position of an object to the center then subtracting half of it's width. (not sure if that makes sense, just look at the code. lol)

something like this:

Code: Select all

w = love.graphics.getWidth()
	love.graphics.rectangle("fill", w/2 - 50, 10, 100, 100)
