Translate. The translate() function allows objects to be moved to any location within the window. The first parameter sets the x-axis offset and the second parameter sets the y-axis offset. 

  
   
  float x, y;
  float size = 40.0;
  
  void setup() 
  {
    size(200,200);
    noStroke();
    frameRate(30);
  }
  
  void draw() 
  {
    background(102);
    
    x = x + 0.8;
    
    if (x > width + size) {
      x = -size;
    } 
    
    translate(x, height/2-size/2);
    fill(255);
    rect(-size/2, -size/2, size, size);
    
    // Transforms accumulate.
    // Notice how this rect moves twice
    // as fast as the other, but it has
    // the same parameter for the x-axis value
    translate(x, size);
    fill(0);
    rect(-size/2, -size/2, size, size);
  }
