dot(5);
Example: Large Dot
Draw a really big dot.
// Draw a really big dot.
dot(150);
Example: Fill the Screen
Draw a huge dot to change the color of the entire screen.
// Draw a huge dot to change the color of the entire screen.
penColor("red");
dot(300);
Example: Mickey Mouse
Draw Mickey Mouse with three dots.
// Draw Mickey Mouse with three dots.
penUp();
dot(100);
moveForward(125);
turnLeft();
moveForward(75);
dot(50);
turnLeft(180);
moveForward(150);
dot(50);
Example: Dalmatian
Draw a lot of random sized dots at random locations.
// Draw a lot of random sized dots at random locations.
penUp();
for (var i = 0; i < 500; i++) {
moveTo(randomNumber(0,320), randomNumber(0,450));
dot(randomNumber(1, 10));
}
