MindCraft AI

MindCraft AI is a powerful GOAP (Goal-Oriented Action Planning) system for Unreal Engine 5.5, built in C++ for maximum efficiency. Designed to seamlessly integrate with MetaHuman technology, it enables your human-like NPCs to think, plan, and act naturally, making them behave with lifelike intelligence and adaptability. Whether it's decision-making, tactical planning, or dynamic responses to the environment, MindCraft AI brings unparalleled realism to your NPCs.

GOAP is not just for games—similar goal-driven AI systems power real-world autonomous space exploration vehicles like NASA’s Curiosity rover and lunar landers. These spacecraft analyze objectives, plan sequences of actions, and adapt to unexpected challenges—just like MindCraft AI enables NPCs to do. By leveraging GOAP’s dynamic action selection and replanning capabilities, your NPCs will respond intelligently to changing conditions, prioritize objectives, and operate with the same kind of autonomy seen in cutting-edge robotics and space technology.

Goal-Oriented Action Planning is planning architecture designed for real-time control of autonomous character behavior in games. Originally implemented GOAP for F.E.A.R. This A.I. architecture simultaneously powered Monolith's Condemned: Criminal Origins.

A Finite State Machine (FSM) dictates exactly how an AI should behave in every situation, following predefined rules and transitions. In contrast, a planning system like GOAP (Goal-Oriented Action Planning) provides the AI with goals and available actions, allowing it to dynamically determine the best sequence of actions to achieve those goals.

FSMs are procedural, requiring explicit state transitions for every possible scenario, whereas GOAP is declarative, enabling AI to evaluate, plan, and adapt in real-time. This flexibility allows for the emergence of complex, human-like behaviors in NPCs, making them more intelligent, unpredictable, and lifelike.

R.E.A.C.T.O.R System

R.E.A.C.T.O.R. is the ultimate enhancement for GOAP-driven AI, bringing NPCs to life with dynamic personality-driven decision-making. Unlike traditional AI systems that rely solely on logic and pre-scripted behaviors, R.E.A.C.T.O.R. introduces Reflexes, Endurance, Accuracy, Courage, Temperament, Observation, and Resolve, creating NPCs that think, adapt, and react realistically. Each attribute dynamically influences GOAP action planning, allowing NPCs to make choices based on their physical and psychological state—a cautious scout may avoid combat, while a fearless soldier charges forward. Integrated seamlessly with GOAP, R.E.A.C.T.O.R. ensures that NPCs are not just goal-driven but also personality-driven, leading to organic, emergent behaviors where no two AI characters act exactly the same. This makes AI encounters feel fresh, challenging, and deeply immersive, perfect for next-generation gaming experiences.
