By putting the pen down, you are getting ready for your Sprite to draw. A line will be drawn from the Sprite's current location to a next location that the Sprite moved. The lines will continue to be drawn as the Sprite moves around the stage until the pen is positioned up.
- Click on the Actions toolkit
- Scroll down to the Drawing section
- Drag the Pen Down block into the editor
- Move the Sprite to a new location to draw a line
- Use the Pen Upblock to move the sprite without drawing
