Multiple Scene Code Example

// Three_Act.pde
// Example code that shows how set up a sketch that has multiple scenes/acts/stages
// 1. declare a variable to remember what scene we are on
// 2. create a seperate function responsible for drawing each scene
// 2. in draw() use if/else to call the function for the current scene

Homework

Next week is the project crit. All three acts of your work should be working.
