1:34 Skip the Introduction to Lesson 14.4 4:00 Skip scene setup and watch a random number creation. 7:52 Skip to the creation of the set_background method. 19:09 Skip directly to the Lesson 14.4 Challenge Program. Lesson 14.4 continues the introduction of parameters in Alice and introduces the concept of Random Numbers to Alice. While Random Numbers are a large topic in of themselves, their introduction during the parameters lesson will allow you as a programmer to make more interesting programs. In addition, we are very close to moving forward to interactive programming, where parameters and random numbers are a highly important skill. Due to the length of this video, it has been split into 2 parts. Part 1 sets up a small object-parameter based method and sets up the initial scene. Part 2 integrates the inclusion of random numbers into a random scene generator. This is an introductory series of Alice Tutorials. This course, from start to finish, is designed to help someone who has never programmed before learn the basics of coding. Alice is appropriate for all age levels and is taught to new programmers usually from about Junior High School, although there are concepts and features that can be entertaining to even skilled programmers. As this series continues, we examine more advanced Alice techniques, functions, and methods. You can download a copy of Alice 2.4.2 from http://www.alice.org. This series was based on a lack of step by step tutorials available at this point. While good tutorials do exist, they are spread across multiple channels and often times don't have a step-by-step learning process. Following this series of videos should provide solid examples and explanations from very basic to more advanced concepts.
