Preface

This module is one in a collection of modules designed primarily for teaching GAME 1343 Game and Simulation Programming I at Austin Community College in Austin, TX. These modules are intended tosupplement and not to replace the textbook.

An earlier module titled Getting Started provided information on how to get started programming with Microsoft's XNA Game Studio.

Object-oriented programs exhibit three main characteristics:

  • Encapsulation
  • Inheritance
  • Polymorphism

I have explained encapsulation, inheritance, and compile-time polymorphism in earlier modules. Before I can explain runtime polymorphism, however, I need tostep back and explain some concepts involving type conversion, casting, and assignment compatibility.

General background information

Type conversion

This module explains type conversion for both primitive and reference types.

Assignment compatibility

A value of a particular type may be assignment-compatible with a variable of another type. If so, the value can be assigned directly to the variable.
