In this add on, you will hide each scene
so the users can't see what happens next.
The starter project includes a sprite
called screen transition, click it.
In the looks menu, click the show block
to make it appear.
Click the costumes tab and look at the costumes.
Each costume reveals part of the screen.
Begin by setting the first costume.
From the looks menu, drag out a switch costume block.
From the drop-down menu, choose screen transition one.
Click it to test.
Only the first scene shows.
Add a when flag clicked block.
When you added new sprites,
they appeared in front of the screen transition sprite.
Fix this by adding a go to front block from the looks menu.
Place the screen transition sprite
in the center of the screen using a go to x y block,
with values of zero and zero.
Next, change the costume to reveal the next scene.
Drag out another switch costume block
and select screen transition two.
From the events menu, drag out a when I receive block
and attach it above the switch costume block.
Use this same block stack for each scene.
Right-click it and select duplicate.
Change the drop-down in the when I receive blocks
and the set to costume blocks.
Test it out.
Now the users see one part at a time in your story.
(door creaking)
(footsteps pounding)
(wolf howling)
Now it's your turn.
Position the screen transitions sprite correctly
with a go to x y block and a go to front block.
Reveal each new scene when it starts using the
when I receive and switch costume blocks.
