Kommandos
Gib etwas mit print aus.
Frage etwas mit ask.
Wiederhole etwas mit echo.
Willkommen bei Hedy! In Level 1 kannst du die Befehle print, ask und echo verwenden.
Hedy benutzt englische Wörter für Befehle wie die meisten Programmiersprachen. print bedeutet drucken oder auf den Bildschirm ausgeben, ask bedeutet fragen und echo bedeutet wiederholen.
Auf der linken Seite deines Bildschirms befinden sich alle Befehle des Level 1.
Drücke den blauen Knopf und der Code wird für dich ausgegeben!
Probiere den Code selbst mit der grünen Schaltfläche 'Code ausführen' unter dem linken Programmierfeld aus.

Make a story
In level 1 you can make a story with a different main character that you enter yourself.
As the first line, use this code:
ask who is the star in your story?
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.
Example Hedy code
ask The main character of this story is
print The main character is now going to walk in the forest
echo He's a bit scared,
print He hears crazy noises everywhere
print He's afraid this is a haunted forest
Let's draw
In level 1 you can also use Hedy to draw. By combining turns and lines, you can make a square or a stair!
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.
This is the start of some little stairs. Can you make it to 5 steps?
Example Hedy code
forward 50
turn left
forward 50
turn right
Rock, paper, scissors
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.
Example Hedy code
print what do you choose?
ask choose from rock, paper or scissors
echo so your choice was:
Restaurant
In level 1 you can make your own virtual restaurant and take your guests' orders.
Example Hedy code
print Welcome to Hedy's restaurant
ask What would you like to order?
echo So you would like to order...
print Thanks you for your order!
print It's on its way!
Challenge
Can you think of more lines to add to your restaurant code? For example, can you ask the guests what they'd like to drink, tell them the price, or wish them a pleasant meal?
Fortune Teller
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:
Example Hedy code
print Hello, I'm Hedy the fortune teller!
ask Who are you?
print Let me take a look in my crystall ball
print I see... I see...
echo Your name is...
Challenge
Hedy now only tells you your name. Can you expand the code so that Hedy can predict more things about you?
Obviously, Hedy isn't a very good fortune teller yet, as she can only repeat the answers that were given by the players! Take a look in level 2 to improve your fortune teller.
Haunted house game
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.
Example Hedy code
print How did i get here?
print I remember my friend telling me to go into the old mansion...
print and suddenly everything went black.
print But how did I end up on the floor...?
print My head hurts like Ive been hit by a baseball bat!
print What's that sound?
print Oh no! I feel like Im not alone in this house!
print I need to get out of here!
print There are 3 doors in front of me..
ask Which door should i pick?
echo I choose door...
print ...?
Challenge
Can you finish the scary story? Or make up your own haunted house story?
What's next?
Congratulations! You've reached the end of level 1. Hopefully you've already made some awesome codes, but Hedy has a lot more to discover.
In the first level you might've notice that the echo command can only save one bit of information at a time.
For example in the restaurant adventure, you could echo what the costumer wanted to eat, or what they wanted to drink, but not both in one sentence.
print Welcome at Hedy's
ask What would you like to eat?
echo So you want...
ask what would you like to drink?
echo So you want...
If the player types a hamburger and coke, you can't say so you woudl like a hamburger and coke, but you have to make two seperate line.
Also, the echo command only echoes the word at the end of the sentence. So you can't say your hamburger is coming right up!.
That changes in level 2. In level 2 you'll learn to work with variables, that allow you to save multiple pieces of information and print them in any place you want.
Besides, you'll learn how to work with the at random command, that you can use to make games.
So let's go to the next level!
