IT 111 Unit 2 Assignment

Unit outcomes: 

  • Use classes, objects, and predefined methods to create a simple movie or animation.
  • Prepare code to implement a given algorithm. 

Course outcome(s) practiced in this unit: 

IT111-1: Recognize the elements of object programming: classes, objects and methods to application development. 

Instructions: 

In this assignment, the objective is to learn how to use the Alice 3 IDE (Interactive Development Environment) to set up an initial scene, and then to add methods (procedures) for adding action to your animation. You are provided a problem and an algorithm to guide your work.

Problem: 

The most famous introductory computing programming problem is known as "Hello, world."  This program appeared in the first edition of a textbook, The C Programming Language, written by Brian Kernighan & Dennis Ritchie in 1972. The "Hello, world" problem has become a traditional way of introducing programming in introductory computer programming courses. Following this tradition, your first programming assignment is to create an animation program where Alice and the White Rabbit greet each other, turn to face the camera, and then Alice waves and says "Hello, world!"

Algorithm: 

  • Do in order
    • Alice turns to face the white rabbit
    • Alice moves forward 4 meters
    • Alice says “Hello Rabbit”
    • Rabbit says “Hello Alice. You are late.”
    • Do together
      • Alice turn to face the camera
      • Rabbit turn to face the camera
    • Alice says “Hello world.” 

Initial Scene: 

1. Use the Scene Editor in creating an outdoor scene where Alice will meet the white rabbit. Objects in this scene are created from models in the Prop package in the gallery. Select the Prop package in the gallery, as shown here:

Then select models from the Prop package. The example shown here will create a pond object.

Add several plants and rocks around the pond to create an initial scene environment that looks something like this (you can be creative here using any trees, shrubs, rocks, or other items you want in your scene):

Now, add Alice and the White Rabbit to the scene. To create an Alice, use the SIMS character builder, found in the Bipeds package. Then, add a WhiteRabbit (also from the Biped package). 

When completed, the initial scene should look something like this (your scene may have different environment objects, but must have Alice and the white rabbit):

Camera Markers

  1. In the scene editor, mark the original camera point of view, using the name camera_originalView. The image below illustrates the steps: 

  1. Use the camera navigation controls (indigo arrows at the lower edge of the scene editor) to move the camera's starting position so that Alice is standing off screen, to the left. Do not move Alice; just move the camera so Alice cannot be seen in the camera's point of view, as shown here:

  1. After completing the scene set up, return to the Code to create program code that implements each step in the algorithm. Your instructor will provide examples of how to add methods (procedures) to the program that allows implementation of an algorithm.
  2. After you have added the methods, go to Window on the Main Menu at the top. Select Programming Language, Java Code. Select Java Code on the Side so that the Java code for your methods is displayed on the right side of the screen.
  3. Save the Alice world as HelloWorld. Alice3 will automatically add a filename extension, .a3p. (Do not type the extension yourself.) Your instructor will provide information regarding saving the world file during Seminar.

Requirements:

    • Add objects to a scene – required objects are Alice and the White Rabbit and any environment props desired.
    • Add code in the code editor to accomplish all lines of the provided algorithm.
    • Save the animation as an a3p file. Submit the Hello World.a3p file to Dropbox. 

HINT:  It is important to save your project every 15 -20 minutes.  Each time you save it, use File/Save As and give the project name a new version number.  For example:  HelloWorldv2, HelloWorldv3, HelloWorldv4. This naming/saving technique, known as version backups, is commonly used by professional programmers to avoid loss of work if something goes wrong during the development process.
