Unreal Engine includes game AI systems such as behavior trees, blackboards, navigation, and the Environment Query System. EQS can score candidate locations or actors to inform decisions. These systems commonly implement authored decision logic; they do not imply an embedded language model or reinforcement-learning pipeline.
Build a small scene in which an agent must reach a target, find cover, and recover when a path is blocked. Inspect blackboard values and query results while debugging. Test missing targets and unreachable locations so the agent has deliberate failure behavior.
No. This guide covers built-in game decision and navigation systems. A generative model would require a separately evaluated integration.
Use it when a decision requires scoring candidates in the environment, such as cover locations, then inspect the query results while testing the behavior.
