Frogger, Page 4

In this page, we will:

• Make a "Level Up" Mini-Splash Screen
• Make a "Frogger Has Died" Mini-Splash Screen
• Make a "Game Over" Full Splash Screen
  (including a "New Game" broadcast)
• Make a "Welcome" Full Splash Screen

Mini-Splash Screen
on "Level Up"

First, click this button to create a new Sprite.

Go ahead and create your "Level Up" mini-splash screen.


Now, to make the code:

1. When we receive the BROADCAST Level Up
   
2. SHOW the splash screen
3. WAIT 2 seconds (or less)
4. HIDE the splash screen

Oh, and while you're at it, you might want to:

• WHEN the green flag is clicked --> HIDE
  and...
• GO TO X __ Y __
  before the SHOW

When you've followed all of these instructions, your "Level Up" mini-splash screen code should look like this:

Mini-Splash Screen
on "Frog Has Died"

Making a second mini-splash screen is almost exactly the same as the first.

Create the object (sprite) and the code is the same except for the broadcast message that is received.

And this means that a broadcast message must be sent at the right place - when the Frogger realizes that it is dead.

Splash Screen
on "Game Over"
(part 1)

The code for
BROADCAST "GameOver" 
has been made before
(to be sent after the last life is gone).

Therefore, all we need is a new object (a splash screen that is full size) and similar code blocks to the ones used for the mini-splash screen.

When drawing, be sure to click the "=" button so that you know your splash screen is the right size!  Watch video if you can't find this button.

Can you figure this all out before the next video?

Splash Screen
on "Game Over"
(part 2)

Two problems:

1. Making the "Game Over" splash screen to appear properly.
2. Allowing the player to play again.

This video solves the first problem, and allows the player to see how many points and levels they achieved.  (The next video will show how to let a player "Play Again".)

Here's the code for this video:

Play Again using
BROADCAST NewGame

Through our code, we have often used: 

• "When the Green Flag is Clicked"
  

Now, we change these to:

• "When I Receive [New Game]"
  

Also, if you add:

• When the Green Flag is clicked,
  then HIDE

Then, you also need to add:

• When I receive [New Game]
  then SHOW

Splash Screen
on "Welcome"

The Welcome splash screen similar but not the same as the GameOver splash screen.

So, duplicate the GameOver object, change the text and colour.  (I chose green.)

Then, you need to fix the code so that the Welcome splash screen appears when the green flag is clicked.

Also, you'll need to change your Frogger code.  
You don't want the Frogger to BROADCAST NewGame when the green flag is clicked. (That's why the cars were changing while the Welcome screen was showing.)
