Description
This function will draw text to the screen using the foreground spritesheet as the font. Sprite #256 is used for ASCII code 0, #257 for code 1 and so on. The character 'A' has the ASCII code 65 so will be drawn using the sprite with sprite #321 (256+65). See the example below or check out the In-Browser Demo
- To simply print text to the screen using the system font, please see print
- To print to the console, please see trace
Example
-- title: Font Demo
-- author: PaulR
-- desc: Shows the working of font()
-- script: lua
function TIC()
cls()
-- The # character is ascii code 35
-- so the sprite with ID 256+35 (#291)
-- will be used to draw that character
-- A and B have ascii codes 65 and 66.
-- Sprites 256+65 (#321) and 256+66
-- (#322) will be used to draw those
-- letters
font('#AB',20,20,2,9,9,true,3)
-- The above prints '#AB' at position
-- 20,20. The sprites use color 2 as
-- transparency colorkey, are drawn 9
-- pixels apart with fixed width and
-- scaled up by a factor of 3
