I am using Alice 2 and need assistance with exercise 7 in chapter 7 which reads as Choose a ride object other than the carousel from the Amusement Park gallery that moves is a circular pattern. Circular pattern means that it moves in a round-and-round manner (e.g., the Ferris Wheel). Create a method that performs an animation appropriate for the ride object selected. Then, create a way to start and stop the ride using the While is true event. For example, you could add a switch to your world that could be clicked to start and stop the ride. I unfortunately cannot get my program to stop.
