Default Driving Test - 04-12-2010, 12:43 AM

Hello. I am having trouble with project 3 in chapter 6. I can get the car to move freely but not sure how to stop the car and have text appear when I touch a cone. Help would be much appreciated. Thanks!

Unfortunately, I have no idea what you mean by "project 3 in chapter 6," probably because I don't have any of the Alice textbooks.

I have to maneuver a car around some cones and if the car hits a cone the car stops and text appears. I have created three methods for the car movements forward, left and right using the while ... is pressed. I'm not sure how to make the car stop and the text appear when I hit a cone.

Are you able to post your current world? I'll take a look and see what I can suggest.

Ok I would suggest having a Boolean variable to see whether you can move or not, then have each of the "while [key] is pressed do" include an "if" statement to test whether the car can be moved.

Then you can do what shaydon suggested, only include at the beginning of the method a statement that changes the variable value.
