An Open-Source Visual Tool for Modeling, Validating, and Exporting Decision Trees for Game Development
Resumo
This work presents VisNeed, an open-source visual tool for modeling, validating, and exporting Decision Trees for interactive applications. Beyond simple visualization, it supports rapid prototyping of business logic, narrative flows, and interaction rules. Aimed at digital games, embedded systems, and educational platforms, it aligns with model-driven development, user-centered design, and agile workflows. Validated trees are exported in JSON format compatible with game engines and runtime systems, enabling seamless integration. VisNeed is designed to support collaboration between technical and non-technical stakeholders through clearer documentation, traceability, and shared understanding—making it a valuable asset in multidisciplinary projects.
