Figure 12-1. Shape Builder and Animator Example sketch
You should play with this sketch some to see what it can do. Besides running the sketch, I
also recommend messing with some of the variable values declared at the top of the
program.
To give you a better understanding, I’ll now go over the sketch a section at a time.
// Shape Builder and Animator Example
float nodeRadius = 5.0;
// holds node coordinate values
float[]nodeXPos = new float[0];
float[]nodeYPos= new float[0];
color initialNode = color(0);
boolean isShapeClosed = false;
//dynamics variables (moves shape)
float gravity = .95;
float jitterRange = 5;
float elasticRangeMin = .75;
float elasticRangeMax = .95;
float friction = .85;
float[]jitter = new float[0];
float[]xSpeed = new float[0];
float[]ySpeed = new float[0];
float[]elasticity = new float[0];
