7) SetDirection and SetPosition

Sometimes you don't want to worry about what direction you need to go or how far it is. bob.setPosition(x,y) will take you directly to a location. Rember that the turtle draws when its tail is down so pull it up if you don't want to draw while you reposition your turtle.

Turtle bob = new Turtle();

bob.setPosition(100,100);

bob.setPosition(100,-100);

bob.setPosition(-100,-100);

bob.setPosition(-100,100);

bob.home();

In the same vein, sometimes you don't want to figure out what direction you are facing and calculate the angle you have to turn to go in the direction you want. bob.setDirection(angle) will point you in the right direction. (Right is angle=0. Up is angle=90.)

Turtle bob = new Turtle();

bob.forward(200);

bob.home();

bob.setDirection(120);

bob.forward(200);

bob.home();

bob.setDirection(240);

bob.forward(200);
