Stop an object in motion with events
 
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 :confused:

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

[SIZE="2"]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

I apologize for this response benig so late. I understood what you were saying and got it working thanks to you. The help was much appreciated! I hope you can excuse my delay though. I run on a rather busy schedule so late in the year and just now got time to get back around to this forum.


Thank you!
