Services in Game Worlds: A Semantic Approach to Improve Object Interaction

The primary objective of this research is to address the lack of functional depth in virtual game environments by introducing a semantic framework for object interaction. While modern games often excel in visual fidelity, they frequently struggle with objects that lack meaningful behavior beyond simple decoration or scripted events. The proposed solution defines "services"—the capacity of an entity to perform an action subject to specific requirements—to allow objects to behave in ways that align with player expectations, thereby enhancing immersion and gameplay complexity.

The methodology employs a three-phased approach to integrate these semantics: a specification phase for building a library of generic classes, a customization phase for tailoring these classes to specific project needs, and an instantiation phase for placing objects into the game world. By utilizing the WordNet database to populate generic libraries and applying inheritance-based ontologies, the system promotes reusability and consistency across development projects. A prototype system was developed to validate this workflow, demonstrating that objects aware of their own services can facilitate more intuitive and varied interactions.

Key findings indicate that this semantic approach effectively bridges the gap between static geometric models and functional, interactive entities. By treating services as a core component of object design, developers can create environments where objects possess inherent behaviors, such as a vending machine that requires currency to dispense items or a heater that modifies the temperature of surrounding entities. The research concludes that while this framework significantly improves object interaction, it remains a tool to support, rather than replace, the creative judgment of game designers, who must balance realism with gameplay flow to avoid unnecessary complexity.
