1 - Introduction

Welcome to our exciting coding adventure! Today, we are going to create a fun game called 'Shark Attack'. In this game, you will control a character who needs to avoid the enemies that are chasing them. We will be using a platform called MakeCode Arcade to build our game. Don't worry if you haven't coded before, we will guide you through each step. Let's get started!

2 - Create a new Arcade project

3 - Create your player sprite

Next, you will create your player sprite. This is the character that you will control in the game. Add the following code:

let mySprite = sprites.create(img`...`, SpriteKind.Player)

Then click on the grey box and choose a sprite character from the gallery.

let mySprite = sprites.create(img`

4 - Move the sprite

Now, let's make your sprite move using the joystick (or the arrow keys on your keyboard).

Add the following new code:

let mySprite = sprites.create(img`
    . . . . . . f f f f . . . . . . 
    . . . . f f f 2 2 f f f . . . . 
    . . . f f f 2 2 2 2 f f f . . .

    . . . . . f f . . f f . . . . . 
    `, SpriteKind.Player)
controller.moveSprite(mySprite)

Once you've added the new code, test that you can move your player sprite with the joystick or your keyboard arrow keys.

5 - Make it stay on the screen

You may have noticed that you can move your sprite off the screen. To stop your sprite from moving off the screen, add the following new code:

let mySprite = sprites.create(img`
    . . . . . . f f f f . . . . . . 
    . . . . f f f 2 2 f f f . . . . 
    . . . f f f 2 2 2 2 f f f . . . 
    . . f f f e e e e e e f f f . . 
    . . f f e 2 2 2 2 2 2 e e f . . 
    . . f e 2 f f f f f f 2 e f . . 
    . . f f f f e e e e f f f f . . 
    . f f e f b f 4 4 f b f e f f . 
    . f e e 4 1 f d d f 1 4 e e f . 
    . . f e e d d d d d d e e f . . 
    . . . f e e 4 4 4 4 e e f . . . 
    . . e 4 f 2 2 2 2 2 2 f 4 e . . 
    . . 4 d f 2 2 2 2 2 2 f d 4 . . 
    . . 4 4 f 4 4 5 5 4 4 f 4 4 . . 
    . . . . . f f f f f f . . . . . 
    . . . . . f f . . f f . . . . . 
    `, SpriteKind.Player)
controller.moveSprite(mySprite)
mySprite.setStayInScreen(true)

Now check that you can't move your player sprite off the screen edges.
