Post Help with tutorial (basic) - 03-02-2012, 01:22 PM

My project is to create an environment where a coach, girl, and scientist are supposed to listen to the evil ninja when he commands them to kick (Tutorial 7-2 of the Starting Out With Alice 2e book). This is to be accomplished by using a list and the For All Together command. I got the ninja to give the command, but cannot get the group to respond. I attached my error message, and I would greatly appreciate any help with this dilemma. The actual problem reads:

The evil ninja has started teaching karate classes to his three students. Create a world that shows the ninja commanding his students to practice kicking. Each time the ninja says "Kick!" the students will simultaneously kick with their right legs. The ninja commands them to kick five times.









Error during simulation.




Alice version: 2.2 12/01/2011



Throwable that caused the error:

It is an error with the December version. Use the previous version or this http://www.cs.purdue.edu/homes/aik_min/. If you are using the new version, after download, you will need to update the software using "Alice update" menu in "help" menu.
