Quests are a fundamental storytelling mechanism used by computer role-playing games to engage players in the game's narrative. Although role-playing games have evolved in many different ways in the last years, their basic narrative structure is still based on static plots manually created by game designers. In research project, we present a method for the generation of dynamic quests based on hierarchical task decomposition and planning under non-determinism. The proposed approach combines planning, execution, and monitoring to efficiently handle nondeterministic events and support quests with multiple endings that affect the game's narrative and create interactive and dynamic story plots. These plots are directly or indirectly affected by player's actions and decisions.

Prototype Application:

In order to validate the proposed methods for the dynamic generation of quests, we developed a prototype 2D RPG using the proposed architecture to dynamically generate and control the entire narrative of the game. The narrative pertains to a zombie survival genre and tells the story of a family that lives in a world dominated by a zombie plague. The player controls the brave husband John through several nondeterministic quests to protect his family and save his own life.
