Diver Game

In this game you dive underwater to collect starfish but be careful of the shark chasing you!

1 - Create a new Scratch project

Create a new Scratch project and delete the cat sprite.

In this game there will be 3 sprites

  1. a diver that you will control with your mouse
  2. starfish that will appear in a random position and you will collect
  3. a shark that will slowly follow and try and catch you

2 - Add the Underwater 1 backdrop

Add the Underwater 1 backdrop to the project.

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

4 - Add the Starfish sprite

Now add the Starfish sprite to your project.

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.
