Draws text on screen. If no Font is set, one will be created and set (once) if needed.

As of LOVE 0.7.1, when using translation and scaling functions while drawing text, this function assumes the scale occurs first. If you don't script with this in mind, the text won't be in the right position, or possibly even on screen.

Function

Synopsis

love.graphics.print( text, x, y, r, sx, sy )

Arguments

string text
The text to draw.
number x
The position to draw the object (x-axis).
number y
The position to draw the object (y-axis).
number r (0)
Orientation (radians).
number sx (1)
Scale factor (x-axis).
number sy (sx)
Scale factor (y-axis).

Returns

Nothing.

Examples

A lame example

function love.draw()
    love.graphics.print("This is a pretty lame example.", 10, 200)
    love.graphics.print("This lame example is twice as big.", 10, 250, 0, 2, 2)
    love.graphics.print("This example is lamely vertical.", 300, 30, math.pi/2)
end

Notes

love.graphics.print stops at the first '\0' (null) character. This can bite you if you are appending keystrokes to form your string, as some of those are multi-byte unicode characters which will likely contain null bytes.
