3 - Set Up Game Elements

Let's set up the game elements. We will create a player sprite and a target sprite.

Add the following code and design your player and target sprites:

let mySprite = sprites.create(img`
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5

    `, SpriteKind.Food)

Make sure you select Food as the kind of sprite for your target sprite.

You can design the player and target sprites however you wish, or choose characters from he gallery. In our example we are using a yellow square as the player and a red X as the target.

4 - Move the Player

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`
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5

    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    `, SpriteKind.Player)
controller.moveSprite(mySprite)
let mySprite2 = sprites.create(img`

    . 2 . . . . . . . . . . . . 2 . 
    2 . . . . . . . . . . . . . . 2 
    `, SpriteKind.Food)

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

5 - Move the Target

Now let's add code to move the target to a random place at the start of the game.

Add the following new code:

let mySprite = sprites.create(img`
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 . . . . . . . . . . 5 5 5

    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 
    `, SpriteKind.Player)
controller.moveSprite(mySprite)
let mySprite2 = sprites.create(img`
    2 . . . . . . . . . . . . . . 2 
    . 2 . . . . . . . . . . . . 2 . 
    . . 2 . . . . . . . . . . 2 . . 
    . . . 2 . . . . . . . . 2 . . . 
    . . . . 2 . . . . . . 2 . . . . 
    . . . . . 2 . . . . 2 . . . . .

    2 . . . . . . . . . . . . . . 2 
    `, SpriteKind.Food)
mySprite2.setPosition(randint(0, 160), randint(0, 120))

Make sure you select MySprite2 in the set position block.

In the pick random blocks put in the values 0 to 160 for X and 0 to 120 for Y. The screen is 160 in width and 120 in height so these values ensure that the food sprites can appear anywhere on the screen, from the very top to the very bottom, and from the far left to the far right.

Now at the start of the game, the target should go to a random position on the screen.
