1 - Create a new Scratch project
Create a new Scratch project and delete the cat sprite.
In this game there will be 3 sprites
- a diver that you will control with your mouse
- starfish that will appear in a random position and you will collect
- a shark that will slowly follow and try and catch you
Go to the Scratch website using the link below and click on the 'Create' link in the blue bar at the top.
By default, each new project starts with the cat sprite already added. To delete the cat click on the x in the blue circle beside the cat in the sprite list.
2 - Add the Underwater 1 backdrop
Add the Underwater 1 backdrop to the project.
To add a backdrop from the backdrop library follow these steps:
- Put your mouse over the Choose a Backdrop button
- Click on the magnifying glass
- Find the backdrop you want in the library
- Click on your chosen backdrop
You can use search box or the filter links (Fantasy, Music, Sports etc) to locate your backdrop.
3 - Add and program the Diver1 sprite
Add the Diver1 sprite from the sprite library. We are going to program the diver to always point towards your mouse pointer and move towards it. This is how you will control where the diver swims to.
Add the following code to the Diver1 sprite.
when green flag clicked
go to x (150) y (0)
set size to (50) %
forever
point towards (mouse-pointer v)
move (4) steps
end
To add a sprite from the sprite library follow these steps:
- Put your mouse over the Choose a Sprite button
- Click on the magnifying glass
- Find the sprite you want in the library
- Click on your chosen sprite
You can use search box or the filter links (Animals, People, Fantasy etc) to locate your sprite.
4 - Add the Starfish sprite
Now add the Starfish sprite to your project.
To add a sprite from the sprite library follow these steps:

5 - Hide the Starfish and create a clone
At the start of the game the starfish will appear in a random position and each time you catch a starfish a new one will appear somewhere else.
Add the following code to the Starfish sprite to change it's size, hide it and create a copy of it.
when green flag clicked
set size to (30) %
hide
create clone of (myself v)
We will program what to do when it's copied in the next step.
