print

print(text, [x=0], [y=0], [color=15], [fixed=false], [scale=1], [smallfont=false]) -> text width

Parameters

text : any string to be printed to the screen
x, y : coordinates for printing the text
color : the color to use to draw the text to the screen
fixed : a flag indicating whether fixed width printing is required
scale : font scaling
smallfont : use small font if true

Returns

text width : returns the width of the text in pixels.

Description

This will simply print text to the screen using the font defined in config. When set to true, the fixed width option ensures that each character will be printed in a 'box' of the same size, so the character 'i' will occupy the same width as the character 'w' for example. When fixed width is false, there will be a single space between each character. Refer to the example for an illustration.

To use a custom rastered font, check out font.
To print to the console, check out trace.

-- author: Vadim
-- desc:   print text perfectly centered
-- script: lua
-- input:  gamepad

cls()
local string="my perfectly centered text"
local width=print(string,0,-6)
print(string,(240-width)//2,(136-6)//2)

function TIC()end

--Prints text where x is the center of text.
function printc(s,x,y,c)
    local w=print(s,0,-8)
    print(s,x-(w/2),y,c or 15)
end

Extended print function

Extended print function that automatically go to line, align text in various ways, allow to use special characters, etc. Translation tools and extended print are independent.
