Kingdom Come: Deliverance 2 is a large open-world story-driven historic RPG where the designer's control over the non-playable characters is of paramount importance. However, instead of dealing with tedious details of NPCs' behaviors, the designers are more interested in describing the wanted results instead of a way to get to them.In this session, Matej Marko presents how KCD2 utilizes a combination of Goal Oriented Action Planning and Modular Behavior Trees to implement behaviors of its NPCs. He describes how the state of each NPC is represented and how MBTs are used to specify the desired NPC's state and to trigger a state change process. Within this process, the desired NPC's state is used as a goal for GOAP which finds actions necessary to get NPC from its current state into the desired state.
