PROFILE

Derek Simpson

Over a three-month period, contributed to the GDACollab/Well-Witches repository by architecting and implementing a scalable enemy and boss AI system using Unity and C#. Developed a modular state machine framework to streamline enemy behavior prototyping, enabling rapid iteration and extensibility for new archetypes and boss encounters. Integrated assets and prefabs to support testing workflows, while refactoring legacy systems to improve maintainability and reduce merge conflicts. Enhanced combat mechanics by introducing phased boss logic, attack indicators, and refined damage timing, laying groundwork for future content. Focused on clean scene management and collaborative code integration, emphasizing robust, data-driven AI and gameplay systems.

January 2025 monthly summary for GDACollab/Well-Witches: Focused on building a scalable AI testing framework using a state-machine architecture to accelerate enemy behavior development and evaluation. Delivered core AIController with State and Transition structures and provided test assets and scene configuration to enable rapid iteration. Implemented placeholder enemy PNG and prefab to bootstrap testing. Prototyped core behaviors with AttackState, PatrolState, and IdleState, establishing a repeatable pattern for adding new states. Completed a stability fix to the AI prototype to improve reliability in testing scenarios. Updated the AIPrototypeScene.unity to align with the new framework and testing workflow. These deliverables enable faster QA cycles, better tuning of enemy behavior, and a foundation for data-driven AI improvements.
