Click on the object's trait and the costumes tab.

You can choose a new costume from the scratch library.

You can upload an image from your computer or you can draw your own image.

This video will show drawing a new image.

But you will follow the same steps, no matter how you added the costume.

But you will ad a costume that fits your story.

You can use filled circles and ovals to easily draw many shapes and animals.

Give the costume a name that makes sense for what you drew.

You will use this name later.

Next, add an event, so your new costume can be used in your story.

This project contains starter code that allows the other costumes to be used in your story.

And you should understand this code to add your new costume.

Try clicking an event to see what happens.

Clicking "when I receive sign", makes the store sign appear and move.

When the, when I receive signs tag has clicked, a variable called costume stores the costume name sign.

Next, the create clone block, instructs the computer to create clone or copy of the spray.

And that causes the, "when I start as a clone block" stack to run, which switches the costume to whatever is stored in the variable costume.

In this example, sign.

To add code for your new costume, click on the events menu and drag out a, "when I receive block".

Click on the drop down, select "new message" and enter name that makes sense for the costume you added.

This example uses duck.

Add a set costume to block to the event stack.

Type the exact name of your costume in the set book.

In this example, the costume name is duck.

The name you type must exactly match the name you used for your costume.

If you forget the name, go back to the costumes tab to check it.

Now, click the stack tutorial.

Great, the variable stores the costume name duck.

Click the control menu, add a create clone block to the end of your stack and choose object from the drop down menu.

The costume variable set to duck, a clone is created and it glides across the screen.


Lastly, add your new costume into your story so you can show it off.

Add a broadcast block from the events menu and choose your new costume from the drop down.

Now it's your turn.

Add a new costume to the object's trait.
