I have a question.

[nevon]

Doesn't Font:getWidth() require a string as an argument?

[kikito]

You are completely right - I've corrected my post.

[com_1]

Code: Select all

function love.load()
  scrx = 640; scry = 480; zx = (scrx/2); zy = (scry/2); zi=200; 
  love.graphics.setMode(scrx, scry, false, true, 0);
  font = love.graphics.newFont("courbi.ttf", 15); --changed 'setFont' to 'newFont'
  height = font:getHeight();
end

function love.draw()
  love.graphics.line(zx - zi, zy, zx + zi, zy); love.graphics.line(zx, zy - zi, zx, zy + zi);
  love.graphics.setFont(font); -- invoked setFont here
  i = "Thanks people";
  width = font:getWidth(i); -- moved getWidth here and added the string
  love.graphics.print(i, zx - (width/2), zy + (height/5));
end

com_1, do take a look at love.graphics.printf(). It's very handy when you're just trying to center text. Saves you the trouble of having to do a bunch of getWidth()/getHeight().

local myStr="Hi there"
love.graphics.print(myStr,myX-myFont:getWidth(myStr)/2,myY)

I'm afraid that love.graphics.draw (for images) has the 'cx,cy' params, but print/printf don't - unless the wiki is incomplete.

You don't need them. love.graphics.printf( text, x, y, limit, align )

So to center text between x=100 and x=300, at y=400, do:

Code: Select all

love.graphics.printf("Our text", 100, 400, 200, "center")

[com_1]

Code: Select all

//With
love.graphics.printf("Thanks people", 320, 240, 0, "center")
//or
love.graphics.printf("Thanks"..(" ")..("people"), 320, 240, 0, "center")
//Not possible

This image with PRINTF.

Code: Select all

//With
love.graphics.printf("Thanks people", 320, 240, 0, "center")
//or
love.graphics.printf("Thanks"..(" ")..("people"), 320, 240, 0, "center")
//Not possible

Why the second one, may I ask?

[zac352]

Code: Select all

love.graphics.printf("Thanks"..(" ")..("people"), 320, 240, 0, "center")

I don't understand why that wouldn't work.
"Thanks" "people" of course wouldn't, unless you set the metatable of strings to automatically concatenate when __call is used.
