UPDATE:
The instructions below are for the older Scratch 2.
For the newer Scratch 3 instructions, click here.



Frogger, Page 3

In this page, we will:
  • Create a separate finish area and then code Frogger to "Level Up" when it gets there
  • Keep track of points
  • Keep track of lives
  • Set speed to increase on level up

You must complete

before starting here!

New to Scratch 2?

If you haven't used Scratch 2 before, check out:
  • Introduction to Coding
  • How to use Scratch 2
  • Introduction to Scratch 2 (with exercises)

Create a Separate Finish Area.
Then Make "Level Up"

First, remove the red "Finish" area from the Stage (Background).

Second, create a new red "Finish" object that looks just like what we erased.  However, now that the Finish area is an object, the Frogger can SENSE it!  So, inside the Frogger code, we need:
IF TOUCHING "FINISH"
--- do a celebration!!

In the celebration" code area, we can make a sound effect, GLIDE back to the START area.
Then, and most important, we want to Level Up!

So, third, create a VARIABLE called "Level".  We must keep track of levels, so we can make the game harder has the levels go up!  So, into our celebration code, we want to add "CHANGE LEVEL BY 1".

Keeping Track of Points

Now that we're this far, adding Points is super easy!

  1. Create a Variable called Points!
  2. Start the game with zero points.
  3. Add some points in the celebration area.
  4. Take away points in the "Frog is dead" area.
And you get to choose how many points are added or taken away!


And remember negative numbers from Math class?
Here's another time that we need them!
Don't know what code blocks to use? Here they are!
(Watch the video if you need help knowing where they go.)

Keeping Track of Lives

Familiar with making variables now?  Great!

So here's your task:
  1. Create a variable called "Lives".
  2. Start the game with some lives.  (I did "3".)
  3. In the "Frog is Dead" area, take away a life. (Same as with points.)
  4. Right after taking away a life, you need to check if there are fewer than one life!  If yes, then BROADCAST "GameOver" and 
    STOP This Script.
    (BROADCAST is under the "Events" palette and
    STOP is under the "Control" palette.)
Again, here are the code blocks, and you can watch the video to see where they go.

Set the Speed to Increase on "Level Up"

Now, life starts to get complicated!

What should we do to make different levels harder?

Let's increase the speed of the cars, but only every 3rd level.  (Yikes!!!)

  1. Create a variable called Speed.
  2. Start the game with a slow speed (I use 3.)
  3. Every 3rd level, increase the speed by 1.
    (Use MOD to do this.)


Then, just to make our lives easier later (but more complicated now), let's add a BROADCAST "Level Up" every time we celebrate touching the Finish area!

(Remember, MOD is under the "Operators" palette and
BROADCAST is under the "Events" palette.)

Again, here are the code blocks, and you can watch the video to see where they go.
