statemachine.cs

// Example of a simple state machine.
// The script has 3 states for different actions it might be performing.  It transitions between the states based on user input.
// State "start" does nothing; state "slowcube" makes the object named "cube" slow down; state "spiralsphere" makes the sphere object spiral outward.
// It can transition from "start" to "slowcube" OR "spiralsphere" depending on what button is hit.
// After that, it can transition from "slowcube" to "spiralsphere" or from "spiralsphere" to "slowcube" when fire1 is hit.
