In this section we will:

• keep track of the number of frogger's Lives
• stop all cars when the frogger dies.
• start all cars when frogger is alive.
• stop all cars when the finish area is reached (Level up!)
• change the costume of the dead frogger
  (and change back when frogger is alive again!)
• have cars change costumes with every teleport
• add more cars on levels 3 and 6

This video shows a new way to communicate between scripts using:

We haven't made a "broadcast" before, so, you'll need to get them from the Control palette.

Everyone knows that the game should stop when the frogger dies.  So, let's make that happen.

We've already created a broadcast called "Died".

Now, let's go to first car (Blue Car) and include a stopping script.

When you've got the Blue Car working, why not just drag that piece of script onto the other cars!

Well, we thought this was a great idea to have the cars stop when the frogger died.

But now, we've created another problem.

The best part is that our solution is simple and will save us work later!

If the cars can stop moving when the frogger dies, shouldn't they also stop when the frogger reaches the finish area?

What does a dead frogger look like?

Hmmmmm....

Add a new costume.

Switch to the right costume at the right time.

If the frogger can change costumes, then why can't the cars?

If the car changes costume when it's teleporting, then we can pretend that there's lots more cars on the road.

I've had a number of questions about adding more cars.  Well, it's time!

Duplicate a car in the slow lane.

Then, when the green flag is clicked, choose "HIDE".

Then, when the Level is right, choose "SHOW".

Sounds simple, right?
