In this add on, you will
showcase various fashion trends
by allowing the user to press the one
and two keys to select different models.
To switch between models, click the model sprite
and select the costumes tab to see the different models.
Drag out a switch costume block from the looks menu
and choose a different costume in the drop down menu.
Try it out!
Nice!
Add a when key pressed event above this block
and select one from the drop down menu.
Duplicate this block stack and repeat
the steps for the second model.
Change the when key pressed event
to the number two and the value
in the switch costume block to a different costume.
To switch to more models duplicate
the when key pressed block stack
and change the values in the when key pressed event
and switch costume block.
Click the flag to test.
When the one and two keys are pressed
the program changes models, but wait, there's a bug!
The same description shows up for different models.
To fix that, click the lens sprite.
Drag out an if then condition from the control menu
and place it around the if then block
that checks which sprite is being touched.
Place an equals block from the operators menu
inside the if then block.
Next, add an attribute of block from
the sensing menu to the first block.
An attribute of block says X position of stage,
but it can be changed to describe many parts of any sprite.
Change the attribute of block
to costume name and the item to model.
Type the sprite's costume name after the equals sign.
Test it out.
Different models no longer show the same description.
Great!
To describe a different model,
reuse the code that you made for the first model.
Computer scientists often reuse code to save time.
Click the lens sprite, select the scripts tab
and duplicate the if then condition
containing the attribute of block.
Place the block stack below the if then block
that checks which sprite is being touched.
Change the costume name.
Wait!
The program describes the first model's
fashion innovation again!
To fix this, create code that reacts only
when the correct colors are touched for the second model.
Click the stop sign so the lens stops following your mouse.
Click the color inside the touching color block.
The mouse-pointer becomes a selection hand.
Use the hand to click on the second model's outfit.
Type text in the say blocks that describe
the fashion innovation for each piece of clothing.
To describe other pieces of the outfit,
change the touching color block to another color
and change the text in the say blocks
to describe the new part of the outfit.
Do these steps for every part
of the outfit you want to describe.
Test the program.
Awesome!
Tell the user how to switch between different models.
Click on the model sprite, drag out a say block
and place it below the other say blocks.
Run the program.
When the one or two keys are pressed,
the program changes models and showcases
how each fashion innovation is unique.

Now it's your turn.
Use switch costume and when key pressed blocks
to switch between different models.
Use if then, equals, and attribute of blocks
to describe a specific model.
