<body class='hmmessage'><div dir='ltr'>That Chapter covers quit a bit of material including lists and poses. The Tips and Techniques should give you several useful options to accomplish this task.<BR> <BR>1) Create a parallel set of poses for each character that perform the wave. Each unique pose for a character in a set should have the same name as the parallel poses for the other characters.<BR> <BR>2) Create a list of character objects.<BR> A "for all in order" loop should be a piece if cake using set poses for the list items.<BR> <BR>Another alternative would be to create a complete "wave" method for each character. The catch here is that there is no direct way to create method call for a list item. You can, however, use "if" statements that compare the current list item with each object, and call the appropriate object method it there is a match.<BR> <BR>Programming Fun, <BR> <BR>Mike Owen <BR> <BR><br>> We're using the Dann, Cooper, Pausch "Learning to Program with Alice" 3rd Edition, Prentice Hall, 2012 textbook in our Computer Programming class.<br>> <br>> Chapter 9, page 280, Exercise 9-1 has an interesting real-world problem: In Alice practice processing a List (in order) where each of four persons executes "the wave" (a popular cheer in football or basketball games).<br>> <br>> The problem suggests using four people: coach, student1, skaterGirl, and randomGuy2. However two of these objects articulate their arms differently than the others. It is very difficult for students to re-position the arms of coach and student1. I tried myself for more than an hour, finally giving up.<br><BR> </div></body>
