a port of the Processing Visualization Language


HLine h1 = new HLine();

float[] speeds = new float[3];

float ypos;

void setup() { 

  size(200, 200);

  speeds[0] = 0.1; 

  speeds[1] = 2.0;

  speeds[2] = 0.5;



void draw() {

  ypos += speeds[int(random(3))]; 

  if (ypos > width) { 

    ypos = 0; 





class HLine { 

  void update(float y) { 

    line(0, y, width, y); 


Description Creates a "new" object. The keyword new is typically used similarly to the applications in the above example. In this example, a new object "h1" of the datatype "HLine" is created. On the following line, a new array of floats called "speeds" is created.
