The print command

You can print text to the screen using the print command.

The ask command

Now that you can use the print command, you are ready to learn the next command: ask. With the ask command, you can ask a question. Check it out:

Create your own online pet parrot that will copy you!

In level 1 you can start with a rock, paper, scissors game.

With ask you can make a choice, and with echo you can repeat that choice.

In this adventure you are working towards making a game in which you have to escape from a haunted house by picking the correct door. If you pick the right door you'll survive, but if not a terrible monster might...

In level 1 we start our haunted house game by making up a scary story and ask the player what monster they'll see in the haunted house.

In level 1 you can make a story with a different main character that you enter yourself.

In the first line, use ask and ask who the main character of the story will be.

After that first line, start with print if the sentence needs to be printed. You use echo if you want your main character to be at the end of the sentence.

In this level you'll learn how to use the play command to play a tune!

Type play followed by the note you want to play. The scale goes C-D-E-F-G-A-B. As you can see there are 7 different letters, but we can play more than just 7 notes. Type a number between 0 and 9 behind the letter to choose the scale, for example after B4 comes C5. C0 is the lowest note you can play, B9 is the highest.

Exercise

Try out the example code and then play around with it! Can you create your own melody? In the next level you'll learn how to play some existing songs.

You can also use Hedy to draw. By combining turns and lines, you can make a square or stairs!

Using forward you draw a line forwards. The number behind it determines how far the turtle will walk. turn right turns a quarter turn in clockwise direction, turn left turns counter clockwise.

If you want to go backwards, you use the forward command but with a negative number. So for example forward -100

Have you ever been to a carnival and had your future predicted by a fortune teller? Or have you ever played with a magic eight ball? Then you probably know that they can't really predict your future, but it's still fun to play!

In the upcoming levels you can learn how to create your own fortune telling machine! In level 1 you can start off easy by letting Hedy introduce herself as a fortune teller and let her echo the players' answers. Like this:

Welcome to a debugging adventure. Debugging a code means getting rid of mistakes in the code. That means that in these debugging adventures, we will show you code that does not work yet. You will have to figure out what's wrong and correct the mistakes.
