Solar System<\/span><\/h1>\n

Core Concept<\/h3>\n

This prototype is intended to be a visualization of\u00a0Classes and Objects<\/strong> in object-oriented programming.<\/p>\n

Why?<\/h4>\n

Classes and objects are fundamental to object-oriented programming languages like Java. Object-oriented programming is often difficult for students who are only familiar with sequential programming because code is more fragmented. We wanted this prototype to give students a chance to experience classes and objects in action without the need to worry about syntax.\"\"<\/p>\n

The Pitch<\/h3>\n

Learn how classes and objects work in space! Store planet classes in an inventory around your left hand (unique to virtual reality) and use them to create full-scale planets to fill your solar system.<\/p>\n

The Actual Experience<\/h3>\n

Build your own custom solar system by designing model planets and using them to build unique planets.<\/p>\n

\"\"Key Interactions:<\/h4>\n
    \n
  1. Design model planets by selecting different sets of features, like size, color, rings, and moons.<\/li>\n
  2. Use the models to create unique individual planets, then set them loose to orbit your sun.<\/li>\n<\/ol>\n

    \"\"Key\u00a0Lessons:<\/h4>\n
      \n
    1. Classes act as templates for objects and define which attributes an object will have. (Model planets act as templates for planets in orbit and each model has a particular set of attributes.)<\/li>\n
    2. Objects are initialized with specific values for their attributes and then instantiated. (Individual planets are customized by setting the values for each of their features and then sent to orbit.)<\/li>\n
    3. Many objects can be created from the same class. (A planet model can be used to create many individual planets.)<\/li>\n
    4. Attributes are defined within the class and set when an object is initialized. (Features for a type of planet are selected to make the model, then those features are customized when an individual planet is being created.)<\/li>\n<\/ol>\n
