Built in Functions

• We need to tell Processing we want to use functions by first using it's own built in functions

• Processing has 2 built in functions to break up the drawing commands into two areas: setup and draw

• • setup() :
  • • called only once when the program is started
    • used to define initial settings (screen size, background, etc)
    • variables inside cannot be accessed from other functions
    • there can be only one setup function
