1. Draw costumes

In this practice we are going to program a game that consists of drawing different characters on the screen applying effects such as rotation or resize.

1. We start the Scratch editor.

   
   

2. Press the language button in the top bar and choose English.

   
   

3. We add a new extension with the button add extension down left.

   We select the Pencil extension to be able to draw.

   

   A new icon will appear in the code bar, the Pencil , with dark green instructions.

   
   

4. In the costumes tab , we delete one of the cat's costumes and add several more characters that we like.

   

   
   

5. Now in the code tab , we are going to add a small program that is executed when the flag is clicked.

   

   
   

6. Press the green flag to test the operation of the program.

   Pressing the flag will clear the entire screen and moving the mouse will cause the cat to move across the screen.

   
   

7. We will complete the program with functions for pressing various keys.

   

   
   

   

   
   

8. Press the green flag to test the operation of the program.

   Pressing the arrow keys now makes the costume increase and decrease in size and rotate from right to left.

   With the space key you will change the costume.

   Clicking on the screen will seal the costume.
