Starting Your Adventure (5mins)

First, you'll need to learn 3 magical commands.

Join your class in PaperLand at https://dojo.paperland.sg/welcome.

Enter your name and press the enter.

On the left side of your magical screen, you'll see ancient text. Select it all and banish it with the delete key.

On the right side, you'll discover your Command Deck with powerful commands!

Cast your first command by clicking fw to move your arrowhead forward.

Watch as your arrowhead moves forward 50 units through the darkness!

In the left code editor, change fw 50 to fw 100 and observe the more powerful magic!

Now, cast your second command called rt to pivot your arrowhead to the right.

Your arrowhead will turn 30 degrees clockwise!

Try changing rt 30 to rt 120 for an even sharper turn!

<aside> 💡

You can also type these magic commands instead of just clicking.

Press the "enter" key on the left code editor to create a new line for your next command.

Type fw 100 to command your arrow to move forward again.

</aside>

Finally, master the third command called lt.

Click lt in your Command Deck to make your arrowhead turn left by 30 degrees.

Armed with these 3 commands, now you're ready for your first quest! 🧙‍♂️✨
