Losing the Game

You may have noticed that the lose My blocks block on the Player Character sprite is empty. You’re going to fill this in and set up all the pieces needed for a nice ‘Game over’ screen.

First, find the lose block and complete it with the following code:

definelosestopother scripts in spritebroadcastgame overgotox:0y:0sayGame over!for2secondssayIt's pretty much impossible to catch all the methane, right?for5secondssayIt would be better to reduce the amount produced in the first place.for6secondssayBy considering the consequences of how we produce food...for5secondssay...we can do it in a more sustainable way that's better for everyone.for6secondsstopall

What does the code do?

Whenever the lose block runs, what it does is:

  1. Stop the physics and other game scripts on the Player Character
  2. Tell all the other sprites that the game is over by broadcasting a message so they can change based on that
  3. Move the Player Character to the centre of the screen and have them tell the player that the game is over
  4. Stop all scripts in the game

Now you need to make sure all the sprites know what to do when the game is over, and how to reset themselves when the player starts a new game. Don’t forget that any new sprites you add also might need code for this!

Hiding the platforms and edges

Start with the basics: The Platforms and Edges sprites both need code for appearing when the game starts and disappearing at ‘Game over’, so add this to each of them:

whenIreceivegame over hide
whenclickedshow

Stopping the farts

Now, for something a little more tricky! If you look at the code for the Collectable sprite, you’ll see it works by cloning itself. That is, it makes copies of itself that follow the special when I start as a clone instructions.

We’ll talk more about what makes clones special when we get to the card about making new and different collectables. For now, what you need to know is that clones can do almost everything a normal sprite can, including receiving broadcast messages.

Look at how the Collectable sprite works. See if you can understand some of its code:

whenclickedsetsizeto35%hidesetcollectable-valueto1setcollectable-speedto1setcollectable-frequencyto1setcreate-collectablestotruesetcollectable-typeto1repeatuntilnotcreate-collectables=truewaitcollectable-frequencysecondsgotox:pickrandom-240to240y:-179createcloneofmyself
  1. First it makes the original collectable invisible.
  2. Then it sets up the control variables. We’ll come back to these later.
  3. The create-collectables variable is the on/off switch for cloning: the loop creates clones if create-collectables is true, and does nothing if it’s not.

Now set up a block on the Collectable sprite so that it reacts to the game over broadcast:

whenIreceivegame overhidesetcreate-collectablestofalse

This code is similar to the code controlling the Edges and Platforms sprites. The only difference is that you’re also setting the create-collectables variable to false so that no new clones are created when it’s ‘Game over’.

Note that you can use this variable to pass messages from one part of your code to another!
