Doodles often animate letters to make them move.
In this video,
you will animate a sprite to make it look like its bouncing.
To do this, you will program it to move
up and down repeatedly.
To start, select a sprite to program
This example uses the G,
but use any sprite you'd like.
Next, program the sprite to move up.
Select the motion menu.
Click, hold and drag out a change y by block.
Click the block to see what it does.
Each click moves the letter up.
Next, program the sprite to move down.
Drag out another change y by block.
Change the value to negative 10.
Click the block.
Each click moves the sprite down.
If you click these blocks repeatedly,
the sprite looks like its bouncing.
Next, program the computer to run these blocks in order.
Attach the blocks and click to run.
The computer runs these blocks so quickly,
you can't see the sprite move.
To fix this, program the computer to wait between actions.
Select the control menu and add a wait block
between the two change y by blocks.
Click to try it out.
The letter bounces once.
Next, program the computer to repeat this action.
Select the control menu.
Click, hold and drag out a repeat block.
Place it around the block stack and click to run.
The sprite bounces,
but not so smoothly.
Add a wait block after the change y by negative 10 block
to make the sprite wait between moving up and moving down.
To change how the sprite bounces,
tinker with the values in these code blocks.
For example, to make the sprite bounce faster
change the value in the wait block to a smaller number.
To make it bounce higher,
change the values in the change y by blocks.
To make it bounce more,
change the value in the repeat block.
Add an event to tell the computer when to run this code.
This example uses a when this sprite clicked block.
But you can use any event you like for your project.
You could run this code when you press a key for example,
or click the flag.
To copy this code to other sprites,
click, drag and drop the code on another sprite.
Click the sprite to check that it copied correctly
and run the code.
Copy this code to as many sprites as you like.
Now it's your turn.
Select a sprite to program
Add change y by 10 wait
and change y by negative 10 blocks.
Add a repeat block around this stack.
Add an event like when this sprite clicked.
Copy this code to as many sprites as you'd like.
Once you've finished these steps,
return to this page to select another video.
