In this add-on, you will program the sprite to have other costumes and expressions.

You can either create a completely new set of expressions, or you can add to an animation that already exists.

This example will add to the Happy costume.

To start, duplicate an Android costume that is similar to the one you want to design.

You may have to drag it to the appropriate spot.

Great, next, edit this costume.

If you don't like something you did or made a mistake, use the undo button.

Play around with the paint editor tools to make something you like.

Feel free to add more than one costume to make cool and unique animations.

Once you have something you like, click back to the Code editor.

If you're adding to an animation, change the animate action block value to reflect the new costumes you added.

If you created a new animated action, make a new block like you did before.

And give it a name that reflects the new animation.

Then add a switch costume block, and set the first costume of the animation.

Next, add an animate action block, and change the value to the number of times the animation needs to change its costume.

Then add the new animated block to the Android's main script to make it part of your story.

Now, it's your turn.

Duplicate an Android costume, then use the vector paint editor to manipulate your Android and further animate a costume or create a new animation.

Edit your code to cycle through more costumes or to create a new animation altogether.
