Xu et al.: Promoting Game Mechanics to Coordinates to Generate Solvable Levels — Fukai Reads
A PCG (level generation) paper by Xu and Verbrugge of McGill University. Against geometry-first prior methods, it proposes HDPCG, which runs pathfinding on a dimensional-expanded graph that promotes mechanics such as gravity inversion and moving platforms to a coordinate, guaranteeing solvability during generation, and reproduces playable levels in Unity.
