Stop an object in motion with events

**Stop an object in motion with events -** 09-26-2010, 02:30 PM

I'm going through the 'Starting out with Alice' textbook and reach an exercise where I have make the a car go around a circular track when you click a button, then stop in its place when you click a different button. However, I can't figure out to make the car stop

Anyone know a way to do this? I've read the Alice book through and through but can't find anything on it. I'm thinking I missed soething.

Thank you

Use boolean variables to control that.

Basically,
Events
When <key> is typed
--<world.variable> set value to <true>
When <other key> is typed
--<world.variable> set value to <false>
Method
While <world.variable>
--car.move

Upload the world as an attachment and I'll show you more specifically.
