arrow_back Grow and Shrink


Here, you will make a letter grow and shrink when it is clicked and add a sound to go with your animation.

The letter in the name will look like it is coming close to the screen, then moving backwards again.

This adds excitement to your animation.

To start, add a new sprite to your project from the Scratch library.

Scroll through the sprites to find the letter you need.

Click on the sprite to add it to your project.

This example uses the letter “A,” but you will add a sprite for the name you are animating.

Next, code the sprite to change size.

Click the scripts tab, and select the “looks” menu.

Click, hold, and drag out a “change size by” block.

Click the block to see what happens.

With each click, the sprite gets larger!

Now that your sprite grows, add code to make it shrink.

Drag out another “change size by” block from the “looks” menu.

Don’t connect your two code blocks together.

The first “change size by” block contains a positive number, and it makes the sprite grow larger.

To make the sprite get smaller, change the value in the second “change size by” block to a negative number.

Click the block to test it.

The sprite shrinks!

To make the sprite grow then shrink, choose the “control” menu, and drag out a “repeat” block.

This type of block is called a “loop.”

It fits around other code blocks to make the blocks inside it run repeatedly.

Place a “repeat” block around each “change size by” block.

Then, connect the two block stacks together.

Click the block stack.

The sprite gets bigger, then smaller.

Nice work!

Next, add a sound that goes with the way your sprite moves.

In an animation, a sound often plays when the character performs an action, like when your sprite grows and shrinks.

To start, click the Sounds tab.

Then choose a sound.

Find a sound you like in the Scratch library. Click the play button to hear the sound.

Select the sound you want to add to your project and click OK.

After you choose a sound, return to the scripts tab.

Select the sound menu.

Click, hold, and drag out a “start sound” block, and attach it to the top of your block stack.

Choose the sound you added from the dropdown menu.

Click the block stack.

The sound you selected plays as the sprite grows and shrinks!

Next, make your animation run when the sprite is clicked.

From the events menu, drag out a “when this sprite clicked” block, and snap it to the top of your block stack.

Click the sprite.

The sprite grows and shrinks, and your sound plays.

Now someone can use the code you created simply by clicking the letter in your name.

Now, it’s your turn: Add a sprite to your project.

Add two “change size by” blocks, one with a positive value and one with a negative.

Add a “repeat” block around each “change size by” block.

Choose a sound from the library.

Add a “start sound” block, and choose your new sound from the dropdown.

And add a “when this sprite clicked” event.
