printToScreen()

Displays print() text output in the running program window.

printToScreen() is a helper function to enable viewing print() output without requiring running L5 from the console or an IDE. This allows, for example, a program to be run simply by dragging its project folder onto the Love application file.

Each call to print() will produce a new line of text in the window. It is particularly useful for debugging.

By default the print size is 16 but a font size can optionally be specified as an argument to the function.

printToScreen() runs continuously overlaying on top of the drawn graphics. Calling print() within the draw() function will cause printed commands to scroll the text output continuously.

Examples

printToScreen example 1

require("L5")

function setup()
  size(100, 100)

  print('hello, world')

  printToScreen()

  describe("prints Hello, World to the screen and console.")
end

printToScreen example 2

require("L5")

function setup()
  size(400, 400)

  printToScreen()

  describe("prints the frameCount, increasing and scrolling the text output.")
end

function draw()
  print(frameCount)
end
