Code:// drawing 2 lines, using one variable
int y = 50;
line(0, y, 100, y); // this line is drawn in black (the default stroke color)
stroke(255, 0, 0); // stroke color is set to red
line(0, y + 10, 100, y + 10); |

Code:// drawing 2 lines, using one variable
// result is similar to the previous example, but the technique used is different
// (the value of the variable is changing at some point)
int y = 50;
line(0, y, 100, y); // this line is drawn in black (the default stroke color)
stroke(255, 0, 0); // stroke color is set to red
y = y + 10;
line(0, y, 100, y); |

Code:// creating concentric circles using one variable and multiplication
ellipseMode(CENTER_RADIUS);
noFill();
int radius = 10;
ellipse(50, 50, radius, radius); // the radius variable holds 10
radius = radius * 2;
ellipse(50, 50, radius, radius); // the radius variable holds 20
radius = radius * 2;
ellipse(50, 50, radius, radius); // the radius variable holds 40 |

Code:// using variables to control colors
// Creating (Homage to Albers)
// by REAS <http://www.groupc.net>
noStroke();
color inside = color(204, 102, 0);
color middle = color(204, 153, 0);
color outside = color(153, 51, 0);
// These statements are equivalent to the statements above.
// Programmers may use the format they prefer.
// color inside = #CC6600;
// color middle = #CC9900;
// color outside = #993300;
fill(outside);
rect(0, 0, 100, 100);
fill(middle);
rect(20, 30, 60, 60);
fill(inside);
rect(30, 45, 40, 40); |

Code:// using float variables and demonstrating why they're useful
float x = 20;
line(x, 0, x, 100); // x is 20
x = x * 1.5;
line(x, 0, x, 100); // x is 30
x = x * 1.5;
line(x, 0, x, 100); // x is 45
x = x * 1.5;
line(x, 0, x, 100); // x is 67.5 |

Code:// some more arithmetics: drawing a disc that is filling almost all of the upper-right corner of the screen
float screen_size = 100;
float x = (screen_size / 4) * 3;
float y = screen_size / 4;
float radius = (screen_size / 4) - 5;
ellipseMode(CENTER_RADIUS);
ellipse(x, y, radius, radius); |

Code:// using predefined variables ("width" and "height"), and doing some more arithmetics...
ellipseMode(CENTER_RADIUS);
ellipse(width / 2, height / 2, (width / 2) - 10, (height / 2) - 10);
line(width / 2, height / 2, width, height); |

Code:// drawing in a "grid-like" fashion, using one variable...
background(0);
noFill();
fill(255, 0, 0);
int gs = 20; // this variable is holding the grid-size
ellipse(1 * gs, 1 * gs, 16, 16);
ellipse(2 * gs, 1 * gs, 16, 16);
ellipse(2 * gs, 2 * gs, 16, 16);
ellipse(2 * gs, 3 * gs, 16, 16);
ellipse(1 * gs, 4 * gs, 16, 16);
ellipse(2 * gs, 4 * gs, 16, 16);
ellipse(3 * gs, 4 * gs, 16, 16); |
