MOO is a text-based virtual reality system that incorporates an object-oriented programming language, evolving from the MUD (Multi-User Dungeon) concept to offer more intricate environments and richer interactions. It includes features like classes, inheritance, polymorphism, and data abstraction similar to traditional object-oriented languages. This platform has become popular for online social interactions and distance learning activities due to its rich world-building capabilities.
Created by Stephen White at Xerox PARC in 1990, MOO was intended to extend the original MUD's capabilities by integrating object-oriented programming features into a text-based virtual reality system. This development allowed for a more sophisticated user experience where participants could engage deeply with the environment through enhanced interactive elements.
MOO competes with other text-based virtual reality systems such as MUSH (Multi-User Shared Hallucination) and MUCK (Multi-User Created Kingdom). While offering similar interactive experiences, each platform has unique features that attract different user bases. The robust object-oriented programming language of MOO provides users with powerful tools for creating complex environments, setting it apart in terms of customization and interactivity. This makes it particularly appealing to those interested in sophisticated world-building activities and immersive online experiences within educational or social contexts.
