L5: A Processing Library in Lua

NoCanvas

noWindow()

Removes the default canvas.

By default, a 800×600 pixels canvas is created without needing to call createCanvas(). noWindow() removes the default canvas for sketches that don't need it. No graphics can be drawn.

Important: No code in draw can continue to run without a window. To have code continue to execute, you must add a update() function and place your code there.

To stop a continuosly updating program from running you may have to figure out another way to quit your program. If launched from the terminal, you can use control-C to cancel/quit.

Examples

require("L5")

function setup()
  noWindow()
end

function update()
  print("running headless")
end
