SIMwagi

SIMwagi is a free and open-source simulation game engine designed for educational purposes, particularly in teaching programming and game development concepts. Created by the University of Wisconsin–Madison, it was originally developed as a tool for introductory computer science courses to help students learn object-oriented programming through game creation. The engine is written in Java and is distributed under the GNU General Public License (GPL), allowing for widespread use and modification.

The name "SIMwagi" combines "simulation" with "wagi," a reference to the WAGI (Wisconsin Advanced Game Initiative) project, which was the precursor to the engine. SIMwagi provides a simplified, two-dimensional game environment where users can create games by manipulating objects, defining behaviors, and implementing interactions. It includes a built-in editor for designing game worlds, setting up objects, and writing scripts in Java, making it accessible for beginners while still offering flexibility for more advanced users.

One of the key features of SIMwagi is its focus on modularity and reusability, encouraging students to experiment with code snippets and object-oriented principles. The engine supports collision detection, physics simulations, and basic artificial intelligence, allowing for a wide range of educational projects. It has been used in various academic settings to teach programming fundamentals, game design, and computational thinking.

While SIMwagi is no longer actively maintained as of recent years, it remains a valuable resource for educators and enthusiasts interested in introductory game development and programming education. Its simplicity and educational focus make it a useful alternative to more complex game engines for teaching purposes. The engine’s documentation and community support, though limited, provide guidance for users seeking to implement or extend its functionality.
