Midterm exam 1 review Sp2006: Make Turtle Boxes
Questions, comments, concerns, answers, concerns about answers?
(Back to Midterm Exam 1 Review Sp2006)
Looks like the little box's corner is in the middle (where the turtle starts) so...
public class MyTurtlePicture {
public static void main(String [] args) {
//FileChooser.setMediaPath("D:/cs1316/MediaSources/");
Picture canvas = new Picture(600,600);
Turtle jenny = new Turtle(canvas);
//Picture lilTurtle = new Picture(FileChooser.getMediaPath("Turtle.jpg"));
for (int i=0; i <=4; i++)
{
jenny.forward(100); //Starts facing up
jenny.turnRight();
}
//Ends at start
jenny.penUp();
jenny.moveTo(jenny.getXPos()-50,jenny.getYPos()+50); //Move 50 left and 50 down
jenny.setHeading(0);
jenny.penDown();
for (int i=0; i <=4; i++)
{
jenny.forward(200); //Starts facing up
jenny.turnRight();
}
canvas.show();
}
}
Yeah. Just used 2 loops. Manabu suggested a 'third box' approach that, in retrospect, seems a lot cooler.
Oh well.
So if I were to make the large box first, could I turn the turtle at a 45 degree angle and have it move forward to start making a smaller box.
Please put your statement in Java code form
| if (I.make(box.larger())) {I.turn(turtle.turn(45)); turtle.forward(box.smaller());}? Is that what you were looking for? :-) (Sorry, just being a smart-aleck...) Mark Guzdial |
