Doodle Draw

This is a basic implementation of a program to draw doodles, using random colors.

It demonstrates:

  • working with colors
  • random RGB color selection
  • input and event handling
  • current and previous frame mouse positioning

From here, you can add additional features such as:

  • buttons to select different colors and brush sizes
  • draw with stamps or photos
  • the ability to save one's drawing to the computer
  • a reset button to clear the screen
  • randomly selected prompts that suggest what to draw
  • a symmetrical drawing mode
  • more experimental features!

Various doodle lines of different colors are drawin in the window

require("L5")

function setup()
  size(800,600)
  windowTitle("Drawing software")

  background("midnightblue")

  describe("A drawing program in a midnight blue window producing random colors each time you draw.")
end

function mouseDragged()
  line(mouseX, mouseY, pmouseX, pmouseY)
end

function mousePressed()
  stroke(random(255),random(255),random(255))
